When I first got my license at age 16, my Father gave me a good piece of advise. When the first Canadian snowfall hits, head to an open parking lot to pull a few donuts and intentional slides. Slam on the brakes and get used to the slide to re-acquaint your brain with recovery from slides and spin-outs using your steering, brakes or accelerator. Been doing it for 53 winters now and it's a great refresher for safe winter driving. Driving and surprises don't work well together.
I have provided the same advice to my 4 daughters - get a good understanding how the vehicle behaves in a safe area first. Then respect its limits. They all carry jumper cables and basic tools in their trunks, just in case.
I didn’t wait for snow. I used to do that in open parking lots anytime I got a higher performance car. I do slides and doughnuts etc. just to get a feel for the vehicle dynamics. Then I’d go join a track day and ask for an instructor
@@grejen711 yes I dad that too, a driving instructor I had made me do it as well (yes, real driving instruction). Now that I am really old, I still go there whenever there is snow and do donuts etc, lifelong good fun
During the summer, when the 4-wheel drive system isn't usually in use, whenever there is a heavy rain, take your truck on the interstate or other high speed roadway and, when on a straight section, engage the auto/4-wheel drive. The wet roadway with higher speeds will allow the tires to slip a little when engaged. Switch back to 2-wheel if you get to a bend or the rain slows down, so you don't chance damage on grippy surface. Auto can of course be used more readily with any rain or loose/slick surface and doesn't need to be disengaged.
@@CodyLynn100 Dude whenever in dought, read the owners manual. hard surfaces are a NO-NO. Yes, the rain will cause wheel slippage, but at what cost? Having an accident is not good for anyone. Besides if you own a 4x4 and don't take in the dirt there is little point in having it. I can always find some dirt, sand, etc. to exercise my transfer case. It's not worth the risk for me, but hey, you do you.
@@gunnersecuador7515 As long as you are driving STRAIGHT you will be fine. Even on a hard surface like concrete. Just make sure to turn it back to 2wd before you make any turns.
I have a 2003 Chevy 2500 and I typically use my drive modes exactly as your suggestions in your video. When I got the truck and noticed the Auto 4WD feature, first thing I did was look at the owner's manual, and it said exactly the same thing. 2WD for normal driving conditions, Auto 4WD for intermittent traction situations, especially typical highway driving in winter conditions, 4 High for more extreme traction, but at speeds between 15mph and 50mph, and 4 Low for low speed situations to get out of a stuck situation. I have only used 4 Low a couple of times ever. I've used 4 High a few times here & there. Auto 4WD, I have used frequently almost every winter, as driving conditions dictated.
I live in the Upper Peninsula of Michigan. Winters are up to 5 months long with easily over 200” of snow yearly. I had a 2002 Chevy Avalanche with the Auto 4x4 feature along with 4 high and low settings. From the first snows, I would put it in the Auto setting and pretty much leave it until spring time. I had the Avalanche for 17 years before selling it. Probably the must reliable 4x4 I ever owned.
@@Freedomwarriors0 : The rust on the 02 Avalanche was almost nonexistent. The frame got rusty underneath. The plastic body panels really protected the sheet metal underneath the panels. My 2014 Silverado is 10 years old and rust everywhere. Rocker panels really bad. Rear fenders lots of rust but no holes.
4 auto is a nice feature I wish I had too. but for the most part, I just put it in 4h and go till I see conditions are good enough to turn it off. that jerking you feel is the binding of the gear in the case. if I feel that. I know conditions are not quite right for 4h. but when you don't feel it doing that, you might feel it slipping a bit on the wheels. that's intentional, its the gears binding enough to put power out and spin freely to avoid damaging itself.
even if off road, 4x4 high can be used if you need speed and momentum, like getting through snow/mud or up a hill. 4x4 low is when are stuck you need slow speed modulation, like 0.5-5 miles per hour to get over obstacles, and also important to read your manual, most trucks have special traction control modes for off road that are usually some combination of 4x4 low + traction control system disabled, and then some kind of brake lock differential will activate for off road mode.
The added benefit of using 4 high is when letting off the gas on slippery conditions, the transmission help slow down the front wheels in addition to the rear.
I'm not sure about the GM trucks, but I know with Ram in 4auto, when you let off the gas, it engages the front diff, and when you hit the brakes, it engages it more.
Just picked up my 24 Colorado z71 today. Searched about 2wd 4hi 4l since im a truck newbie and im glad that I saw your video. Well explained exactly what i needed to know! Thank you for educating me the basic sir!
I drive in Calgary the conditions on the roads are poor at best. I keep my truck in Auto until the roads are cleared. There are patches of black ice underneath some snow patches.
I used to visit the High Desert area in Southern California quite a bit. I found that driving on those sandy roads is a great way to learn to control a vehicle while it is sliding. I taught a number of teenagers to drive, and if I could I took them out to that area initially to teach them how to handle a car.
Thank you. Those are some nice comments. For all my kids (4); I had them practice in a snowy parking lot to figure out how their vehicles would behave. Smash that like button and share!
Thank you for this video. This is a start. I've driven dozens of vehicles over 32 years of holding a driver's license through mild climates like WA state to blizzard climates cold enough to freeze gas and propane lines. I've driven through silver thaws, etc. My dad was lovingly brutal about teaching me to drive. Driving, professionally, runs in my paternal family. I do not drive professionally, but could. It... is.... CRUCIAL... to KNOW the vehicle you're driving. Front wheel drive, rear wheel drive, all wheel drive, open differential, limited slip differential, locked diff, etc.. Knowing how to gear down and how to use throttle play(or not), as opposed to applying brakes, is critical. Knowing which wheels are locked by parking brake and how it is engaged and released for emergency(it just fun in open parking lot) benefit, whether by handle or by foot. MANY things to know. The afore mentioned info doesn't even start to take into account the tires/pressures on the vehicle. There are many reasons so many people, nowadays, end up in collisions or ditches in bad weather even though we have SO MANY modern luxuries and tech in our cars/trucks. I like to be the one in FULL CONTROL of the vehicle I'm driving.
I need to cancel my warranty claim now. I was running my truck in 4Hi due to the snow, but I didn't understand why my truck was jerking while turning the wheel. I thought I was having an engine problem. What a relief this is for me. Thank you so much for explaining this. This has helped me tremendously.
Hi Don, thank you for a great video! I have new Bridgestone Bizzaks on my 2022 Elevation and find I'm always slipping and sliding. Any recommendations?
@@colleenkirkpatrick670 you’re welcome. If you are on a lot of snow and ice, you could lower the pressure in your tires about 10% of their recommended pressure. Keep in mind they will grip better but also wear down a bit faster on dry roads. Especially at high speed. Blizzacks are great tires. If they have the ability for studs, you could get those added too.
Traction control working in the background for 4Auto is a good point. For on-road snow driving, 4Auto (and off-road mode if available) is the way to go. 4H & 4L are specialized for real off road conditions.
4H is also useful on the road when there is significant accumulation that hasn't been plowed. Also, in Michigan many counties like to spread salt on 4+ inches of snow even before plowing. This ALWAYS makes driving worse and 4H is the medicine. One thing he didn't mention was when NOT to use 4H or 4L... When the roads are clear of snow and ice or there are many patches of clear pavement, don't use 4H or 4L. In 4 wheel drive, your front wheels needs to slip intermittently when you turn. If they can't slip because you're on dry pavement, you can damage your driveline $$$.
I’m not an english speaker but I was so impressed with your clear accent while watching. I could understand every single word that you spoke. Thanks for sharing useful tips for driving 4wd.
Very important to note that when ESC is disengaged, it will automatically reengage at 35mph. Ask the guys who were doing high speed drifts and nearly flipped their truck when it kicked back in and applied braking. Love the videos Don, great content all around.
Very true! As far as I'm aware, only the ZR2 trim allows you to leave ESC off above 30km/h through the use of off road mode. Makes the truck much more fun.
FYI to beginners, it wasn’t really mentioned that there is absolutely nothing wrong leaving your vehicle in AWD during any type of road conditions that limit your traction, any rain, slush, snow, ice, mud including intermittent such as the possibility of hitting black ice etc. the reason there is AWD is because it is safe for the vehicle to stay in AWD even on dry pavement. So when in doubt, you are more safe in AWD than 2WD.
I was just going to ask about that. I have a 22 GMC Sierra and this is the first truck I have owned with 4 wheel auto. I was going to ask if you could use it on the open highway. My work commute is 40 miles of highway with a speed limit of 55 mph. I have to be to work on some days by 6am. There have been mornings where the plows haven’t had a chance to get the highway completely clean or they have and the next morning it’s windy and the snow we got from the day before is blowing across the highway in certain areas.
Totally agree with the use of AWD with vehicles like this. If you aren’t sure, it might be better to keep it on. The intent of the video was to share some basic functionality. Tires, tire inflation, weight distribution, acceleration habits, driver experience, etc can all influence the vehicle’s behavior.
Thank you for this comment. I was worried it would damage the transfer case or transmission. The vehicle stays in the mode you select and one time I went a few weeks on auto 4WD until I finally noticed and switched it back to 2WD. The truck runs and feels just fine. Hard to noticed the difference on dry pavement.
@@killer2600 4 Auto is exactly the same as AWD in fact the 4 auto system in my Infiniti was pulled straight from a Nissan sports car. There are lots of different AWD systems. 4 auto works like a lot of high performance sports cars do where they start off in RWD as use a clutch pack to give you variable amounts of traction to the front, which is exactly how this works
I just came out of an 05’ Sierra Denali AWD, and now have a new Silverado with auto 4x4. I also like to use the auto in heavier rains. You explained your points very well, and it all makes sense. Thank you for sharing!
I had a 2002 Chevy Avalanche. I sold it in 2019. I live in Michigan’s Upper Peninsula where it is common to have snow for 5 months every winter. It had the setting for Auto 4x4 along with 2WD, 4H, and 4L. I would leave it in the Auto setting all winter long. The truck only got stuck a couple of times and that was during the late spring heavy wet snows when snow that would build up under the truck. In the 17 years, I changed the oil every 4 months and the trans fluids every two or three years. Best truck I ever owned. I sold it at 240,000 and the only issues were electric motors in power windows were weak as well as power seats. Rust was very minimal as the plastic body panels really worked to protect the truck. The Auto setting worked flawlessly and was instant in kicking in. On our rural road, which took a awhile for plows to clear, occasionally I would use the other 4x4 settings.
I have a 21 Sierra SLT 4x4. I built an H shaped frame of 2x4’s for between the wheel wells, then placed 6 60# sand bags between. Makes a huge difference in slick conditions
Trucks today especially have no weight on the rear wheels any weight in the back helps incredibly. Different tires make a huge difference too. Anytime I can I but BF Goodrich all terrain at . Best tires for the money I believe, on a truck atleast.
I have a 2020 Colorado and use auto quite often and especially in rainy conditions. Auto provides better grip and stability in wet, snowy and even in multiple curved roads.
We live in Florida, it rains a lot here. Me and my wife each drive four-wheel-drive trucks. On rainy days we use auto four-wheel-drive because the roads get slippery. Here in Florida all the roads flood very quickly. You need a truck that sits a little higher than cars. We feel much safer in a four-wheel-drive vehicle.
Thanks for making this video. I purchased a Tahoe with similar features you are demonstrating and was curious when to use them. Perfect timing as Winter weather is starting to hit the eastern United States. Thanks again!
Great video. The best video with accurate information. I watched many videos and they all had wrong information, to the extent I just went and took time to read my manual. And found out, all the other videos were not accurate, but yours is. Thanks again..
Good advice. 2wd most of the time Auto 4wd when you might slip 4wd when you know you will slip 4 low. Off road when you need more control and will be moving slow. With a 10 speed transmission I am not sure how necessary 4 low really is.
Take the opportunity during the snow season and put it through the numbers. Make sure all the 4WD modes work. Don't wait til the last minute to see how or if it works. Give it a work out and for myself anyway, I keep it in 4WD "Auto" during the snow season and if I'm pulling cars from the snow banks, I put it in 4WD High or Low and if I'm buried (one time I was buried so deep, I had to open the windows to get out) I go with 4WD Low. Thanks for the video!
Good video. I got a Pathfinder with the Auto function, LE trim, hoping I could use it for just this reason. Very glad I did. Already used it in intermittent snow and rain recently as I remembered this video as I was driving.
yep, I used 4 wheel auto on my vehicle during winter and also in heavy rain when I would pull out in traffic where there was a higher speed limit. My limited slip had a habit of fishtailing no matter what tires I had on it when in 2 wheel drive. I have a lead foot, lol.
On my Raptor, I love using the power distribution screen when it looks scketchy. I always use 2H until ice or snow hits. Then its time to engage 4A and pull up the power distribution screen. It will show me how much power is being distributed to each wheel. As soon as the bars start to balance from the rear to the front.....esp. if I am on the highways, it is time to lay off the gas and let the truck settle down. I am able to run around with zero concern if I am being too aggressive just by being able to monitor when power is being transferred to front wheels and by how much to each wheel. It shows me before I can even feel it. I agree....I have hardly ever used 4H and don't know if I ever used 4L. (pulling a big boat off steep wet ramp would be my only situation I can think of). I agree with 100% of your post.....besides the GMC part. LOL
Just bought my first truck, used 2015 Chevy Silverado 1500. Thank you for this video. I knew that it had 4x4, I really wanted it for adventuring and winter (had to park my CRV in a field till the neighborhood go plowed last year); but I did not know how to use it. Very excited for the future.
Michigan guy I've only used auto a handful of times. I mostly do 55 or 70 not much in town driving. The times I've used auto where was when the roads have just started to melt and make slush but there are patches of only wet pavement if they are covered in snow and ice I'll keep it in 4h especially since I'm not making hard turns if that's the case I'll put it in 2wd. It really boils down to experience I have rarely maybe 2 times decided 4 low was appropriate. Lots of variables though tires and condition are the biggest. It is important for young drivers or people not used to driving in snow and if someone has bought a new vehicle to pick a parking lot and see how it handles as well.
The jerky movements on the wheels in 4x4 are the u-joints "kinking" up. I was always told only use half your full turning capacity in 4x4 so as not to destination your u-joints.
I've had a few vehicles over the years with a couple different auto settings. My Explorer is in 4Auto all the time, but I have the ability to select 4hi part time and 4lo if needed. My 1st Jeep Grand Cherokee had full time 4WD with a viscous coupler in the transfer case that split power 48/52 typically during normal driving conditions, but had the capability to send full power to the front or rear if needed for traction....I also could select 4Lo if needed, but I had no 2WD option and no part time 4WD option other than low range. My 2nd Jeep Grand Cherokee had the upgraded 4WD system (Selec-Trac) which gave me 2WD, and both full time and part time 4WD high range, and low range as well. No fancy sensors or electronics...just a fully mechanical 4WD system, but I did have a rear limited slip differential in that one. I haven't had a pickup with a 4Auto or full time 4WD setting, all of my 4x4 pickups have only had 4hi and 4lo as well as 2WD....and most were manually shifted with manual locking hubs, lock the hubs the first snow of the season, usually September or October depending on if I went hunting or not, and then shift in and out of 4WD with the lever as needed, then usually I'd forget to unlock the hubs till around May or June LOL.
Well done! People need this education. Two very important points you illustrated. 1. Ice doesn't care what you drive, stopping is really difficult. People need to slow down. (30 car pileup last year in southern Quebec. Oops, I mean Vermont I-89.) 2. 4wd does not handle/steer the same as AWD. Larger turning radius and "jerky" response. At no time, is an AWD/4WD an excuse to drive fast on bad road conditions. I just got a 2024 1500 myself. It's not a mid-life crisis, nor for beating to death off-road. It's for handling everyday driving in the great white north.
Using auto all the time is a good way to get a $4500.dollar bill from the dealership for a warn out transfer case , I never use Auto , Only if I’m worried about black ice occasionally over bridges. If it’s used all the time it goes in out in out and wears out the clutches in the transfer case
Hi Don, thaks for the video. I just got a new 2024 Silverado similar to yours and was wondering how to use these fetures. Now I know and will be prepared for the first serious snow!
Great video. Just bought my 1st truck this yr, 14 Frontier Pro4X(doesn’t have auto). Had some idea about 4x4, but not enough. I was especially surprised by the speed limit in 4wd. I thought all the truck barrelling up the QE2 or out to the ski hills at 130 in January were in 4wd. Added better AT tires, some weight over the axel and now seem to get around most of Calgary winter in 2wd no problem. Thanks again.
No problem, You can drive at high speed in 4High. 4Low is limited by design. If you stay in 4High often, you’ll want to keep up on your inspections and fluid maintenance intervals.
Thanks for the video. I understand now i should be in 2WD 95% of the time.I live in Northern Michigan in Boyne City. We get some good snow and ice here. I just got a 2008 Nissan Titan for a work truck. 265,000 miles. It could use a good look at the transfer case, so I am trying to baby it. This vid helped a lot.
Don i lived by aspen ridge right beside your neighborhood 3 mins away I also have a 2023 tahoe rst diesel...when I watched this video the first minute I was like ,wait I know those streets and and schools..by the way good job on showing us how to use 4x4's helps me a lot specially for a beginner like me..keep it up don..stay warm out there. I'm your new subscriber..
@12:02...my Ford Expedition did the same thing; it was jerky. However, my Toyota Sequoia does not do this; it drives pretty smoothly in the same situation.
My best recommendation is studded tires, I had an AWD wagon and i had hakkapeliitta 10 studded tires and I was able to stop on a "dime" and take off very quickly. the best part was turning, I was able to make a 90⁰ turn going 50 with no tire slip (on a lake with pylons to mimic an intersection). Long story short car was costing too much with premium gas and imported parts and being 20 years old so I decided to get a 4x4 truck and it came with top of the line non studded tires. With 2wd going 20km/h around a 90⁰ turn with just slight throttle I was accidentally drifting corners, with 4wd auto I was able to go 30km/h with less than 25% throttle with no slip. God damn do I miss studded tires they have saved my ass more times than there are wires in both of my cars together.
I wish I had 4-Auto in my Jeep, but most of them didn't come with it (it was an option) and I got my Jeep off the lot so it came as-is. But that's okay, I have other "off-road & inclement weather" capabilities so it's no big deal. The tires are OEM/factory (33" Falken Wildpeak AT3W) and they seem to do well in the snow. Never had an occasion (serious) where I needed 4L (not into the hard-core 4x4ing scene), but I do use it occasionally on dirt/gravel forest/fire roads just to "exercise" it even if 4L isn't needed on them -- AND drive very slowly....not to mention avoiding sharp turns (or turning at all) to avoid crow-hopping (and excessive drive-train wear or possible drive-train damage). However, PUTTING it in 4 low is kind of an art...not at all easy like a push-button and sometimes several tries are needed (could be just me though even following Jeep's instructions). So most of the time I'm in 2H, and when it snows -- and covers the road or there's only occasional pavement -- I put it in 4H just for a bit more traction for safety/stability. But I NEVER drive very fast in 4H, so keep it slow & steady, especially in a white-out blizzards Colorado sometimes get and I'm caught in one while out & about. BTW, nice house & neighborhood there (Canada). "Jeep Wave" ...even though you don't have a Jeep. ;-) -- BR
I have to have my pickup in 4WD just to get up our private road and into our garage every winter. I only use my 4WD when I have to. We’re 5 miles from town and our county road is the last one to get plowed, so we’re always in 4WD usually until we get into town. Sometimes during heavy snow fall the plows can’t keep up so everyone drives slowly on the highway so I’m usually in 4WD during those times as well. I never switch into 4WD on dry pavement.
Crazy I came across your video. Was looking for some extra clarity for driving my 4WD truck properly after these heavy snowfalls. Surprised to see the exact same streets that I drive through Saskatoon (University Heights / Evergreen)! Cheers!
Great video my friend. I just bought a 2023 Yukon XL, 4x4. I'm from Southern CA. Obviously, we never get snow. That said, we do plan on traveling to the snow. My question is, when do you need snow chains? Also, what tires would you apply the chains to? Thanks for the video, it answered many of my questions
Snow chains can usually fit most tires and you’d potentially want them on severe in severe ice/snow conditions and grades when your tires aren’t gripping.
I love 4 auto because I can tell my wife when she takes the truck in winter of course just put it in auto and then I have piece of mind that she will get where she is going. Also I'm not afraid to use it at highway speeds just incase of ice or slush in the middle or passing lanes. Like I said piece of mind.
In North Dakota, we had probably similar weather as to what hit Edmondton, we got a lot of snow over a couple days and it was a couple days until the streets in my hometown in SWND were cleared. We got well around 12 inches of snowfall the first night, or 30cm. My 99 Silverado has basically the same 4X4 system as the new GMC/Chevrolet pickups have. I believe the 99 Silverado/Sierra was the first year this system was offered with the Auto 4X4 engage. However the 6.2L wasn't available at that time, mine is the 5.3L. It's also an extended cab long box so it may be slightly longer wheel base than this truck. I was able to get out both days of the storm and my wife and I did make it to work with the pickup, but I had just left it in 4X4 High, I didn't engage Auto 4X4. But being it was as cold as it was, I did start out in 4X4 Low just to maintain slow speeds. When I was out on the streets after driving for a few minutes, I did switch to 4X4 High to complete the drive to work, and we got around just fine. I'd have no concerns about using Auto 4X4 but due to the conditions, I decided to just run 4X4. We usually don't get a huge amount of snow this early in the season, but sometimes it does happen. I guess it was just our turn this year. Great explanation of how and when to use the system. Too bad you didn't have some deep snow to drive it through to more accurately demonstrate how to use the system and why depending on conditions.
Auto is two wheel when you don’t need it the truck decides based on traction. Feel free to leave it on Auto for the winter. Rest a sure you will be in two wheel more than 90 percent of the time just like your normal.
Auto FWD is helpful for those icy overpasses that catch you off guard especially when pulling a trailer. The wobbling in the front end is the ujoints binding up from the extreme turning angle.
The wobble is from a locked differential. Both wheels are trying to spin at the same speed. The outside tire cannot spin at the same speed as the inside tire though a sharp turn when the diff is locked. Has nothing to do with the u-joints. If this was the case my FWD Prius, and every FWD vehicle would have binding issues with tight turns. Also, it's Auto 4WD not Auto FWD
Always use 2H on dry pavement. When the vehicle is engaged in 4wd，the front wheels rotate faster than rear wheels while turning despite the power output is 50:50 on both axels in order to generate a pulling force to maneuver the vehicle through low traction surfaces. If force the vehicle to be driven on good traction surfaces， what happens is the front and rear axels play tug n war against each other with the drive shaft as the rope，and can damage the drive shaft by twisting it as the twisting force generated by the difference in rotation speed of each axel cannot be released on the ground with good traction.
What mode you are in does in fact effect your ability to stop as well. It puts drag onto the drivetrain as well as removeing the forward passive drive of the vehicle and also can effect the slip or non slip of the differential case. Depending on what you have.
Good day from Ontario. I had 2013 gm 4 wheel lever manual. Bought 2019 & it has buttons like yours. That auto is good art corners but on straight away, I think it is fooling you, by staying in 2 drive u are alittle more aware of road conditions. Thanks good video.
This is a great video! I recently got my first truck (2018 Silverado LTZ Z71) and took it out with the recent snow storm in upstate NY. Most of this info regarding the transfer case was unbeknownst to me, but i assumed 4H was for fast speeds and 4L is for low speed situations. Well I was using 4H and turning felt super jerky, truck was also very noisy. Well the roads i were driving on were mostly down to the pavement and there wasn’t much snow/ice. I did some research because i thought something was wrong with the truck.. came across your video and i have to say thanks for a simple informative explanation. I will now just stay in 2wd or use auto when coming across these situations. I was using 4H when the roads had too much transaction, causing a bit of a binding in the drivetrain.
Glad there was some useful info there! Auto is okay too if you need to leave it on for intermittent periods throughout the day. You just wouldn’t want to leave it on when 2wd would be perfectly safe
I drove up in Canada in the winter down hills. Wheels, wheels my friends matter most then the transfer case. 4x4 helps going up hills. Take care ya hosers!
Thank you very much for such an informative video. I have a 2020 1 ton GMC Denali that i bought when i lived in So. Calif. Asked the salesman to explain the whens and when nots about 4wd and auto modes. He wasn't sure because it never snows where we lived at the beach. Now I live in northern Utah and we recently had our first snow of the season. I put it in 4H to get out of my driveway and drove around town like that. Thanks to your excellent video I will now use the AUTO function . Great job!!!
You have helped me out a lot , I just bought a 2002 Chevy avalanche and it has the Auto 4 wheel drive and the 4 high and the 4 low and it also has the 2 high and I was wondering when I should shift into the 4 high , you have helped me out a lot so I really do appreciate your videos and your doing such a great job 👍👍👍👍 Thank you very much 👍👍👍👍
Here in Iowa we get huge drifts from the constant wind. The roads may be clear but you randomly run into drifts up to 5 feet deep. I stay in 4 high so I can speed up and bust through them
Very helpful video. I too live in a very cold & icy place but in the mountains. 2 questions- • Is there a limit to your speed when switching from 2WD to 4A? How about when switching from 4A to 4H & back? • Is there a speed you should not be driving over when in 4H or 4L? I’m thinking about steep icy inclines or icy mountain passes with a steep grade in blizzard conditions.
Thanks for watching the video! You can double check the owner's manual but shifting from 2WD to Auto4WD or 4High is usually recommended below speeds of 60mph. I also make sure I am driving in a straight line during any changes is settings. 4High doesn't have a set speed once you are in that setting, but I would recommend no more than the speed limit. As for 4Low, it is usually to be kept under 10mph.
Don, I enjoyed your video. One thing I would clarify. You mentioned 4L having "better traction", while driving through deep snow. That is a myth, obviously gear selection cannot affect tire friction with the road surface, and in fact there are some times when selecting a higher gear can decrease the chance of tires slipping. If you are trying to climb a hill, get going from a start, etc., with very limited traction (lots of power and torque are not needed), the key is to apply very smooth and consistent power to each wheel. Internal combustion engines do not produce very smooth and consistent power, think more like impact gun than electric motor. However, the fluid coupling of the torque converter can help smooth that power out. If the vehicle is in 4H you will have to use more engine RPM to initiate movement and with that higher RPM more smoothing will take place. Also, as torque spikes come though the transmission and into the transfer case/driveline they will be less likely to break tire traction in the higher range. Try this the next time you have to get started on a very steep and slippery hill. Put it in 4L and slowly and gently apply throttle until movement is achieved, test how easy it is to not break traction and get moving. Then switch to 4H and try again, slow and smooth throttle pressure. It will be much easier to control in 4H and you will be able to get speed more quickly without breaking traction. As long as you did not overheat the trans fluid you didn't hurt anything or cause wear, you just made better use of your torque converter. The same thing can be achieved in a manual transmission to a lesser degree, use 2nd or third to limit torque spikes. Often better than 1st at getting un-stuck. Maybe not the best to do to a manual trans clutch, but if a gentle start in 2nd gets you out when 1st would not, hopefully not a significant clutch wear event. In addition, I tell drivers to be careful with those "4 auto" settings because whatever clutch or engagement device is being used to connect the front axle when rear axle slippage is detected is subject to wear or breakage. Auto 4WD is better than 4H or 4L for driving at speed around curves on slippery surfaces, because those 4H and 4L settings force the front and rear driveshafts to turn the same speed, even though the front tires travel further on a curve. That results in forced tire slippage in 4H and 4L on curves (the choppy turning you demonstrated), and could cause a vehicle to loose control on a curve in 4H or 4L that it could have successfully negotiated at the same speed in 4 auto or 2WD. But, if 4 auto is being used and the rear driveshaft very quickly increases speed (heavy throttle on ice) and then the front axle is engaged a lot of force is put on those engaging components to very quickly bring the front axle up to the same speed (possible big bang and broken parts).
Thank Russ. It was a tricky video to make while keeping it accessible to people that have never used these options, but have had them for some time. I agree with your statements too. It reminded all the times in my youth getting started in deep snow with a manual tran. Depending on the vehicle, sometimes a 3rd gear start was the smoothest way to get out.
This amount of snow and ice is considered summer up on the North where I live in. People usually roam around with little clothings on a 120hp or less 2wd vehicle if the snow is only this much. We only choose to drive less than 30Mph when there's a Blizzard going over us for 2 days or more and there's like 3 feet or more snow on the road. 4wd is only reserved when you get buried with snow in the parking lot.
I used to own an 03 Tahoe and the only time I ever had to put it in 4x4 was when I was playing in the mud or deep snow for fun. Otherwise 2wd was all I ever needed to get around in winter. The Goodyear Duratrac tires definitely helped too lol
@@Terk131 I have no idea. I bought the truck used and the seller didn’t know much about it. It had auto 4wd and a locking rear diff that I can tell you.
You can probably google a free VIN search and find out some of those details. The G80 Locker has been around for quite awhile and does work pretty good.
@@Donslife I sold it 4 years ago cause it was developing some electrical gremlins. Rear heater fan would randomly turn on by itself, drivers door would go dead (nothing worked) randomly. The list goes on. I got rid of it before it became a lawn ornament lol
One thing to note. Most trucks even new one don't have auto mode. It's just 2 hi 4 hi N or 4 lo. If my wheels were spinning on normal acceleration. I put it in 4 hi but where I live there are steep hills and mountain passes to drive through. I usually only used 4 lo off road and not very often even then. The last time I used 4 lo was to pull out fence posts on a property we bought. The time before that was to pull my friends large trailer from behind his house where he stored it off season. The grass was wet and his truck was only 2 wheel drive. I'm actually to the point I want to find a 4 wheel drive truck from the late 60s to early 70s and fix it up. What little electronics it has are up high and wading through streams I don't need to worry.
Watching this on 2x playback speed is absolutely terrifying. As others mentioned, 4 Low is not for snow or mud. It's generally for terrain that is so rough that you cannot go slow enough in high range to avoid bouncing all over the place. Most people never need to worry about using it.
Last January we had a big snow storm (3ft in 10 hours). We already had 2 ft on the ground, so I had to dig down to open the door on my pickup. I put it in 4 low and literally pushed the snow with my bumper and tailgate to get out so I could wait for the road to be plowed to get to town. I was surprised that my Ranger was able to do it. But I suppose that’s why we’re on our 4th Ranger. Their just good durable mid sized pickup’s. That was the only time I had it in 4low
Our pickup is a 2011 and it doesn’t have automatic 4WD. I have to manually put it in 4WD or manually take it out. Thankfully it’s just a switch on the dashboard. I do miss manually locking front hubs. They tend to last longer than auto locking.
Please correct me if I'm wrong but ... my understanding is that "auto" 4WD relies on the vehicle's computer to detect slippage before it engages. It is useful at low-speed applications like parking lots, local side streets and driveways. If you're traveling at highway speeds using auto mode, you need to remember that "auto" 4WD is intermittent by design and may not engage quickly enough to give you the traction you need, when you need it. In contrast, if you select 4WD Hi mode for highway speeds, it is engaged at all times ... until you deliberately disengage it. That makes it more predictable because you don't have to wait for the computer to detect slippage before it kicks in (which, depending on the conditions, may be too late). 4W high ultimately provides full-time control at higher speeds. One caveat is, that if you're needing four-wheel high at higher speeds, then chances are the conditions are poor enough that you probably wouldn't be traveling at the full speed limit anyway. At least you shouldn't be. Just remember, 4 wheel drive does not mean4 wheel stop!
Very helpful 💯❤️ I purchased a 2013 Chevy Silverado 1500 4x4 with no owners manual unfortunately. I knew my 2000 Ford Expo like the back of my hand but this Chevy has tons of bells n whistles I'm not familiar with! This was helpful for this old school locking hubs kinda girl!
This is an excellent video, I’m very familiar with the four-wheel-drive selections, especially in the GMC family. Very good explanation in the different 4-wheel Drive settings.
I don’t know why I wasted 20 min as I already know this stuff, But that’s a testament to your ability to present the information well. Great video for folks who don’t know these things and nice truck. Cheers!
Have been driving OH/PA winters for almost 40yrs. The ONLY times i use 4wd in my trucks over the years were at stop lights on inclines. Maybe 4-5-6 times a winter. Maybe another 5-6 times driving during/after major snowstorms. And really probably haven't needed it the last handful of winters around here. Not like winters back in the 70's into the 80s.
Great video. Found it very informative I bought a 2018 sierra n the 4 wheel drive is something I was unsure about. I heard you need to stop and put it in park to engage 4 high or low.
Excellent video. I live here in New Zealand, slightly different from Canada. Agree with you with the driving experience. Through winter in the south island here is very similar to Canada's winter. We do have a number of un tarsealed (gravel) roads in country areas which would suit 4 auto in summer. Possibly 4 high Through winter. I personally would leave vehicle in 4 auto for new or learner drivers through winter.
Hello New Zealand! Visited your paradise in early 2000. Took me a while to get used to wrong side drive, and the one at a time single lane bridges were totally new to me. Nicest people I've ever met, in the most beautiful country in the world. Rotorua is amazing.
@@kenbearsley8322 being the most volcanically active place in the world(at the time) the sulfur smell was pungent. I rented a car and did both islands. I don't remember the name of the hotel, but I remember a free drink every night at the pig and whistle. I met a couple from Norway on the first stop of my round the globe trip, in Tahiti, then picked them up again in NZ. I enjoyed every aspect of the country thoroughly, including Rotorua. Paddled down the river thru Christchurch, and rented a house on the beach in Wellington for a couple nights. The world cup yacht race was going on. NZ is spectacular. One of my fondest memories.
I put some weight in the bed of my 2wd pick up truck and get around very good on paved or maintained gravel or dirt roads during winter conditions. However I’m very conservative and don’t attempt to do anything stupid. There are so many people that think they must have four-wheel-drive. I owned four-wheel-drive vehicles before and rarely ever engaged the transfer case. I found myself engaging the transfer case just to keep everything lubricated.
My daily work vehicle is a 93 ranger 2wd. I have studded winter tires and have never got stuck in the 13 years I've had it. With a few concrete blocks and my snowblower in the bed it's impressive! It does have limited slip which does help! I leave my 4+4 pavement princess in the garage to stay salt free!!! Lol
Thank don very informative I have a 2021 slt with all the bells and whistles. I keep it in 2 wheel Drive. But you just gave me some good advice. All your videos and upgrades are very helpful. I wish I could give you a 💯
Actually 4 high has been proven to shorten you stopping distance in slippery conditions because unlike 4 auto 4 high still locks your axles together when braking, evening out the braking distribution
Absolutely because when you're slowing down you're not just swollen using the back wheels. Just like in my Camaro when I was young I downshift too fast let the clutch out and lock up the back wheels
Well done. Good video. Just remember to turn off Auto when the pavement dries up. An old mechanic friend from a Chevy dealership reminded me that Auto is not AWD. When Auto is on the truck is actually in 4WD and the transaxles will wear prematurely on dry pavement.

When I first got my license at age 16, my Father gave me a good piece of advise. When the first Canadian snowfall hits, head to an open parking lot to pull a few donuts and intentional slides. Slam on the brakes and get used to the slide to re-acquaint your brain with recovery from slides and spin-outs using your steering, brakes or accelerator. Been doing it for 53 winters now and it's a great refresher for safe winter driving. Driving and surprises don't work well together.
:) used to do that when I was a kid too. Didn't need any encouragement from dad though!
I have provided the same advice to my 4 daughters - get a good understanding how the vehicle behaves in a safe area first. Then respect its limits. They all carry jumper cables and basic tools in their trunks, just in case.
I didn’t wait for snow. I used to do that in open parking lots anytime I got a higher performance car. I do slides and doughnuts etc. just to get a feel for the vehicle dynamics. Then I’d go join a track day and ask for an instructor
@@grejen711 yes I dad that too, a driving instructor I had made me do it as well (yes, real driving instruction). Now that I am really old, I still go there whenever there is snow and do donuts etc, lifelong good fun
@@grejen711 that last part was not needed
Very informative video.
I have to say , I love drifting in the snow. I'm 64 years old but still like to be a kid myself.
Kids don't drive
It's also a good idea to exercise both axles periodically, to keep the valves working and the fluid moving in the transfer case.
Certainly!
During the summer, when the 4-wheel drive system isn't usually in use, whenever there is a heavy rain, take your truck on the interstate or other high speed roadway and, when on a straight section, engage the auto/4-wheel drive. The wet roadway with higher speeds will allow the tires to slip a little when engaged. Switch back to 2-wheel if you get to a bend or the rain slows down, so you don't chance damage on grippy surface. Auto can of course be used more readily with any rain or loose/slick surface and doesn't need to be disengaged.
@@CodyLynn100 Dude whenever in dought, read the owners manual. hard surfaces are a NO-NO. Yes, the rain will cause wheel slippage, but at what cost? Having an accident is not good for anyone. Besides if you own a 4x4 and don't take in the dirt there is little point in having it.
I can always find some dirt, sand, etc. to exercise my transfer case. It's not worth the risk for me, but hey, you do you.
@@gunnersecuador7515 As long as you are driving STRAIGHT you will be fine. Even on a hard surface like concrete. Just make sure to turn it back to 2wd before you make any turns.
@@CrowT 4X4 mode as far as my experince recalls, should NOT be used for speeds going 60- mph...
I have a 2003 Chevy 2500 and I typically use my drive modes exactly as your suggestions in your video. When I got the truck and noticed the Auto 4WD feature, first thing I did was look at the owner's manual, and it said exactly the same thing. 2WD for normal driving conditions, Auto 4WD for intermittent traction situations, especially typical highway driving in winter conditions, 4 High for more extreme traction, but at speeds between 15mph and 50mph, and 4 Low for low speed situations to get out of a stuck situation. I have only used 4 Low a couple of times ever. I've used 4 High a few times here & there. Auto 4WD, I have used frequently almost every winter, as driving conditions dictated.
Thanks for checking this video out and leaving your thoughts
I live in the Upper Peninsula of Michigan. Winters are up to 5 months long with easily over 200” of snow yearly. I had a 2002 Chevy Avalanche with the Auto 4x4 feature along with 4 high and low settings. From the first snows, I would put it in the Auto setting and pretty much leave it until spring time. I had the Avalanche for 17 years before selling it. Probably the must reliable 4x4 I ever owned.
Hello from Harbor Springs Mi!
How was the rust of the vehicle if you don’t mind me asking?
@@Freedomwarriors0 :
The rust on the 02 Avalanche was almost nonexistent. The frame got rusty underneath. The plastic body panels really protected the sheet metal underneath the panels. My 2014 Silverado is 10 years old and rust everywhere. Rocker panels really bad. Rear fenders lots of rust but no holes.
4 auto is a nice feature I wish I had too. but for the most part, I just put it in 4h and go till I see conditions are good enough to turn it off. that jerking you feel is the binding of the gear in the case. if I feel that. I know conditions are not quite right for 4h. but when you don't feel it doing that, you might feel it slipping a bit on the wheels. that's intentional, its the gears binding enough to put power out and spin freely to avoid damaging itself.
even if off road, 4x4 high can be used if you need speed and momentum, like getting through snow/mud or up a hill. 4x4 low is when are stuck you need slow speed modulation, like 0.5-5 miles per hour to get over obstacles, and also important to read your manual, most trucks have special traction control modes for off road that are usually some combination of 4x4 low + traction control system disabled, and then some kind of brake lock differential will activate for off road mode.
The added benefit of using 4 high is when letting off the gas on slippery conditions, the transmission help slow down the front wheels in addition to the rear.
I'm not sure about the GM trucks, but I know with Ram in 4auto, when you let off the gas, it engages the front diff, and when you hit the brakes, it engages it more.
Just picked up my 24 Colorado z71 today. Searched about 2wd 4hi 4l since im a truck newbie and im glad that I saw your video. Well explained exactly what i needed to know! Thank you for educating me the basic sir!
Glad I could help! Nice truck too
I drive in Calgary the conditions on the roads are poor at best. I keep my truck in Auto until the roads are cleared. There are patches of black ice underneath some snow patches.
I used to visit the High Desert area in Southern California quite a bit. I found that driving on those sandy roads is a great way to learn to control a vehicle while it is sliding. I taught a number of teenagers to drive, and if I could I took them out to that area initially to teach them how to handle a car.
I'm only 2 mins in but I love and trust your delivery...thanks for sharing. I'm going to show my kid this after I watch it.
Thank you. Those are some nice comments. For all my kids (4); I had them practice in a snowy parking lot to figure out how their vehicles would behave. Smash that like button and share!
Thank you for this video. This is a start. I've driven dozens of vehicles over 32 years of holding a driver's license through mild climates like WA state to blizzard climates cold enough to freeze gas and propane lines. I've driven through silver thaws, etc. My dad was lovingly brutal about teaching me to drive. Driving, professionally, runs in my paternal family. I do not drive professionally, but could. It... is.... CRUCIAL... to KNOW the vehicle you're driving. Front wheel drive, rear wheel drive, all wheel drive, open differential, limited slip differential, locked diff, etc.. Knowing how to gear down and how to use throttle play(or not), as opposed to applying brakes, is critical. Knowing which wheels are locked by parking brake and how it is engaged and released for emergency(it just fun in open parking lot) benefit, whether by handle or by foot. MANY things to know. The afore mentioned info doesn't even start to take into account the tires/pressures on the vehicle. There are many reasons so many people, nowadays, end up in collisions or ditches in bad weather even though we have SO MANY modern luxuries and tech in our cars/trucks. I like to be the one in FULL CONTROL of the vehicle I'm driving.
Wow are'nt you special
I need to cancel my warranty claim now. I was running my truck in 4Hi due to the snow, but I didn't understand why my truck was jerking while turning the wheel. I thought I was having an engine problem. What a relief this is for me.
Thank you so much for explaining this. This has helped me tremendously.
You’re welcome. Glad it helped
Hi Don, thank you for a great video! I have new Bridgestone Bizzaks on my 2022 Elevation and find I'm always slipping and sliding. Any recommendations?
@@colleenkirkpatrick670 you’re welcome. If you are on a lot of snow and ice, you could lower the pressure in your tires about 10% of their recommended pressure. Keep in mind they will grip better but also wear down a bit faster on dry roads. Especially at high speed. Blizzacks are great tires. If they have the ability for studs, you could get those added too.
Thank you Don. I'll give that a try with lowering the tire pressure.😀
@@Donslife unfortunately they're a studies winter tire
After many a years of hard work I bought a brand new 2023 ford f150 xlt 5.0 v8 fx4 in January. Never had a 4x4 so I'm definitely a 4x4 newbie.
Thank you for watching!
Traction control working in the background for 4Auto is a good point. For on-road snow driving, 4Auto (and off-road mode if available) is the way to go. 4H & 4L are specialized for real off road conditions.
4H is also useful on the road when there is significant accumulation that hasn't been plowed. Also, in Michigan many counties like to spread salt on 4+ inches of snow even before plowing. This ALWAYS makes driving worse and 4H is the medicine. One thing he didn't mention was when NOT to use 4H or 4L... When the roads are clear of snow and ice or there are many patches of clear pavement, don't use 4H or 4L. In 4 wheel drive, your front wheels needs to slip intermittently when you turn. If they can't slip because you're on dry pavement, you can damage your driveline $$$.
I’m not an english speaker but I was so impressed with your clear accent while watching. I could understand every single word that you spoke. Thanks for sharing useful tips for driving 4wd.
Thank you for the compliment. I a pleased you enjoyed the video
Very important to note that when ESC is disengaged, it will automatically reengage at 35mph. Ask the guys who were doing high speed drifts and nearly flipped their truck when it kicked back in and applied braking.
Love the videos Don, great content all around.
I will continue to avoid that flipping feature 🤔
Very true! As far as I'm aware, only the ZR2 trim allows you to leave ESC off above 30km/h through the use of off road mode. Makes the truck much more fun.
@@clintk4691 Bison guy here.🦬 and front and back locking differentials.
This was actually a very helpful video for a first time truck owner getting ready for the Canadian winter! Thank you!
Glad it was helpful!
FYI to beginners, it wasn’t really mentioned that there is absolutely nothing wrong leaving your vehicle in AWD during any type of road conditions that limit your traction, any rain, slush, snow, ice, mud including intermittent such as the possibility of hitting black ice etc. the reason there is AWD is because it is safe for the vehicle to stay in AWD even on dry pavement. So when in doubt, you are more safe in AWD than 2WD.
I was just going to ask about that. I have a 22 GMC Sierra and this is the first truck I have owned with 4 wheel auto. I was going to ask if you could use it on the open highway. My work commute is 40 miles of highway with a speed limit of 55 mph. I have to be to work on some days by 6am. There have been mornings where the plows haven’t had a chance to get the highway completely clean or they have and the next morning it’s windy and the snow we got from the day before is blowing across the highway in certain areas.
Totally agree with the use of AWD with vehicles like this. If you aren’t sure, it might be better to keep it on. The intent of the video was to share some basic functionality. Tires, tire inflation, weight distribution, acceleration habits, driver experience, etc can all influence the vehicle’s behavior.
Auto 4WD and AWD (All Wheel Drive) are two different things. AWD vehicles don't have 2 HI or any other 4WD selections.
Thank you for this comment. I was worried it would damage the transfer case or transmission. The vehicle stays in the mode you select and one time I went a few weeks on auto 4WD until I finally noticed and switched it back to 2WD. The truck runs and feels just fine. Hard to noticed the difference on dry pavement.
@@killer2600 4 Auto is exactly the same as AWD in fact the 4 auto system in my Infiniti was pulled straight from a Nissan sports car. There are lots of different AWD systems. 4 auto works like a lot of high performance sports cars do where they start off in RWD as use a clutch pack to give you variable amounts of traction to the front, which is exactly how this works
I just came out of an 05’ Sierra Denali AWD, and now have a new Silverado with auto 4x4. I also like to use the auto in heavier rains. You explained your points very well, and it all makes sense. Thank you for sharing!
Thanks for checking out the video. I appreciate it
I had a 2002 Chevy Avalanche. I sold it in 2019. I live in Michigan’s Upper Peninsula where it is common to have snow for 5 months every winter. It had the setting for Auto 4x4 along with 2WD, 4H, and 4L. I would leave it in the Auto setting all winter long. The truck only got stuck a couple of times and that was during the late spring heavy wet snows when snow that would build up under the truck. In the 17 years, I changed the oil every 4 months and the trans fluids every two or three years. Best truck I ever owned. I sold it at 240,000 and the only issues were electric motors in power windows were weak as well as power seats. Rust was very minimal as the plastic body panels really worked to protect the truck. The Auto setting worked flawlessly and was instant in kicking in. On our rural road, which took a awhile for plows to clear, occasionally I would use the other 4x4 settings.
Thanks for sharing man 🙏
I have a 21 Sierra SLT 4x4. I built an H shaped frame of 2x4’s for between the wheel wells, then placed 6 60# sand bags between. Makes a huge difference in slick conditions
Good idea. Do you have a photo of your set up?
Trucks today especially have no weight on the rear wheels any weight in the back helps incredibly. Different tires make a huge difference too. Anytime I can I but BF Goodrich all terrain at . Best tires for the money I believe, on a truck atleast.
I have a 2020 Colorado and use auto quite often and especially in rainy conditions. Auto provides better grip and stability in wet, snowy and even in multiple curved roads.
We live in Florida, it rains a lot here. Me and my wife each drive four-wheel-drive trucks. On rainy days we use auto four-wheel-drive because the roads get slippery. Here in Florida all the roads flood very quickly. You need a truck that sits a little higher than cars. We feel much safer in a four-wheel-drive vehicle.
May I ask why not get an AWD vehicle?

Thanks so much! (and for replying so quickly) Stay warm this winter and safe driving. Cheers. Brian.
Great video. The best video with accurate information. I watched many videos and they all had wrong information, to the extent I just went and took time to read my manual. And found out, all the other videos were not accurate, but yours is. Thanks again..
Thank you 🙏🏻 I appreciate it
Good advice.
2wd most of the time
Auto 4wd when you might slip
4wd when you know you will slip
4 low. Off road when you need more control and will be moving slow. With a 10 speed transmission I am not sure how necessary 4 low really is.
Thanks for checking out the video
love the fact that you used that’s what it takes what it takes for the donuts
🍩 🍩 🍩 🔥
@@Donslife its really what it take
Take the opportunity during the snow season and put it through the numbers. Make sure all the 4WD modes work. Don't wait til the last minute to see how or if it works. Give it a work out and for myself anyway, I keep it in 4WD "Auto" during the snow season and if I'm pulling cars from the snow banks, I put it in 4WD High or Low and if I'm buried (one time I was buried so deep, I had to open the windows to get out) I go with 4WD Low. Thanks for the video!
Good video. I got a Pathfinder with the Auto function, LE trim, hoping I could use it for just this reason. Very glad I did. Already used it in intermittent snow and rain recently as I remembered this video as I was driving.
My first 4 by4 came with wise words. (She will not stop faster Son. Leave room.) My Grandfather had so many wise words.
yep, I used 4 wheel auto on my vehicle during winter and also in heavy rain when I would pull out in traffic where there was a higher speed limit. My limited slip had a habit of fishtailing no matter what tires I had on it when in 2 wheel drive. I have a lead foot, lol.
Best video explaining when to use all this things! Thank you
What a great comment! You’re welcome!
On my Raptor, I love using the power distribution screen when it looks scketchy. I always use 2H until ice or snow hits. Then its time to engage 4A and pull up the power distribution screen. It will show me how much power is being distributed to each wheel. As soon as the bars start to balance from the rear to the front.....esp. if I am on the highways, it is time to lay off the gas and let the truck settle down. I am able to run around with zero concern if I am being too aggressive just by being able to monitor when power is being transferred to front wheels and by how much to each wheel. It shows me before I can even feel it. I agree....I have hardly ever used 4H and don't know if I ever used 4L. (pulling a big boat off steep wet ramp would be my only situation I can think of). I agree with 100% of your post.....besides the GMC part. LOL
Just bought my first truck, used 2015 Chevy Silverado 1500. Thank you for this video. I knew that it had 4x4, I really wanted it for adventuring and winter (had to park my CRV in a field till the neighborhood go plowed last year); but I did not know how to use it. Very excited for the future.
Glad I could help
Michigan guy I've only used auto a handful of times. I mostly do 55 or 70 not much in town driving. The times I've used auto where was when the roads have just started to melt and make slush but there are patches of only wet pavement if they are covered in snow and ice I'll keep it in 4h especially since I'm not making hard turns if that's the case I'll put it in 2wd. It really boils down to experience I have rarely maybe 2 times decided 4 low was appropriate. Lots of variables though tires and condition are the biggest. It is important for young drivers or people not used to driving in snow and if someone has bought a new vehicle to pick a parking lot and see how it handles as well.
I agree man
The jerky movements on the wheels in 4x4 are the u-joints "kinking" up. I was always told only use half your full turning capacity in 4x4 so as not to destination your u-joints.
I've had a few vehicles over the years with a couple different auto settings. My Explorer is in 4Auto all the time, but I have the ability to select 4hi part time and 4lo if needed. My 1st Jeep Grand Cherokee had full time 4WD with a viscous coupler in the transfer case that split power 48/52 typically during normal driving conditions, but had the capability to send full power to the front or rear if needed for traction....I also could select 4Lo if needed, but I had no 2WD option and no part time 4WD option other than low range. My 2nd Jeep Grand Cherokee had the upgraded 4WD system (Selec-Trac) which gave me 2WD, and both full time and part time 4WD high range, and low range as well. No fancy sensors or electronics...just a fully mechanical 4WD system, but I did have a rear limited slip differential in that one. I haven't had a pickup with a 4Auto or full time 4WD setting, all of my 4x4 pickups have only had 4hi and 4lo as well as 2WD....and most were manually shifted with manual locking hubs, lock the hubs the first snow of the season, usually September or October depending on if I went hunting or not, and then shift in and out of 4WD with the lever as needed, then usually I'd forget to unlock the hubs till around May or June LOL.
Well done!
People need this education. Two very important points you illustrated.
1. Ice doesn't care what you drive, stopping is really difficult. People need to slow down. (30 car pileup last year in southern Quebec. Oops, I mean Vermont I-89.)
2. 4wd does not handle/steer the same as AWD. Larger turning radius and "jerky" response.
At no time, is an AWD/4WD an excuse to drive fast on bad road conditions.
I just got a 2024 1500 myself. It's not a mid-life crisis, nor for beating to death off-road. It's for handling everyday driving in the great white north.
Thanks for watching
Using auto all the time is a good way to get a $4500.dollar bill from the dealership for a warn out transfer case , I never use Auto , Only if I’m worried about black ice occasionally over bridges. If it’s used all the time it goes in out in out and wears out the clutches in the transfer case
Hi Don, thaks for the video. I just got a new 2024 Silverado similar to yours and was wondering how to use these fetures. Now I know and will be prepared for the first serious snow!
Great Information, Just bought my first 4x4 truck (23 AT4 3L). Thank you for making this video!
This was intended for folks like you and those who are curious. Congrats on your first truck!!
Great video. Just bought my 1st truck this yr, 14 Frontier Pro4X(doesn’t have auto). Had some idea about 4x4, but not enough. I was especially surprised by the speed limit in 4wd. I thought all the truck barrelling up the QE2 or out to the ski hills at 130 in January were in 4wd.
Added better AT tires, some weight over the axel and now seem to get around most of Calgary winter in 2wd no problem.
Thanks again.
No problem, You can drive at high speed in 4High. 4Low is limited by design. If you stay in 4High often, you’ll want to keep up on your inspections and fluid maintenance intervals.
Ok. I see a lot of articles that say don’t go over 100km in 4WD, just for liability?
Thanks for the video. I understand now i should be in 2WD 95% of the time.I live in Northern Michigan in Boyne City. We get some good snow and ice here. I just got a 2008 Nissan Titan for a work truck. 265,000 miles. It could use a good look at the transfer case, so I am trying to baby it. This vid helped a lot.
Thank you for watching the video
@@Donslife Thanks again for the content!
Don i lived by aspen ridge right beside your neighborhood 3 mins away I also have a 2023 tahoe rst diesel...when I watched this video the first minute I was like ,wait I know those streets and and schools..by the way good job on showing us how to use 4x4's helps me a lot specially for a beginner like me..keep it up don..stay warm out there. I'm your new subscriber..
Haha! Hello neighbor! Say hi if you see me out there!
@@Donslife absolutely 💯 haha
@12:02...my Ford Expedition did the same thing; it was jerky. However, my Toyota Sequoia does not do this; it drives pretty smoothly in the same situation.
My best recommendation is studded tires, I had an AWD wagon and i had hakkapeliitta 10 studded tires and I was able to stop on a "dime" and take off very quickly. the best part was turning, I was able to make a 90⁰ turn going 50 with no tire slip (on a lake with pylons to mimic an intersection). Long story short car was costing too much with premium gas and imported parts and being 20 years old so I decided to get a 4x4 truck and it came with top of the line non studded tires. With 2wd going 20km/h around a 90⁰ turn with just slight throttle I was accidentally drifting corners, with 4wd auto I was able to go 30km/h with less than 25% throttle with no slip.
God damn do I miss studded tires they have saved my ass more times than there are wires in both of my cars together.
I wish we could have studded tires in Michigan.
Our dirt roads are icy right now. Icy enough I am shopping for chains for the tractor.
I wish I had 4-Auto in my Jeep, but most of them didn't come with it (it was an option) and I got my Jeep off the lot so it came as-is. But that's okay, I have other "off-road & inclement weather" capabilities so it's no big deal. The tires are OEM/factory (33" Falken Wildpeak AT3W) and they seem to do well in the snow. Never had an occasion (serious) where I needed 4L (not into the hard-core 4x4ing scene), but I do use it occasionally on dirt/gravel forest/fire roads just to "exercise" it even if 4L isn't needed on them -- AND drive very slowly....not to mention avoiding sharp turns (or turning at all) to avoid crow-hopping (and excessive drive-train wear or possible drive-train damage). However, PUTTING it in 4 low is kind of an art...not at all easy like a push-button and sometimes several tries are needed (could be just me though even following Jeep's instructions).
So most of the time I'm in 2H, and when it snows -- and covers the road or there's only occasional pavement -- I put it in 4H just for a bit more traction for safety/stability. But I NEVER drive very fast in 4H, so keep it slow & steady, especially in a white-out blizzards Colorado sometimes get and I'm caught in one while out & about.
BTW, nice house & neighborhood there (Canada).
"Jeep Wave" ...even though you don't have a Jeep. ;-)

I have to have my pickup in 4WD just to get up our private road and into our garage every winter.
I only use my 4WD when I have to.
We’re 5 miles from town and our county road is the last one to get plowed, so we’re always in 4WD usually until we get into town.
Sometimes during heavy snow fall the plows can’t keep up so everyone drives slowly on the highway so I’m usually in 4WD during those times as well.
I never switch into 4WD on dry pavement.
Crazy I came across your video. Was looking for some extra clarity for driving my 4WD truck properly after these heavy snowfalls. Surprised to see the exact same streets that I drive through Saskatoon (University Heights / Evergreen)!
Cheers!
Glad I could help!
The ending of this video made my day wasn’t expecting it 😂
When there is snow…How could I not?
Great video my friend. I just bought a 2023 Yukon XL, 4x4. I'm from Southern CA. Obviously, we never get snow. That said, we do plan on traveling to the snow. My question is, when do you need snow chains? Also, what tires would you apply the chains to? Thanks for the video, it answered many of my questions
Snow chains can usually fit most tires and you’d potentially want them on severe in severe ice/snow conditions and grades when your tires aren’t gripping.
I love 4 auto because I can tell my wife when she takes the truck in winter of course just put it in auto and then I have piece of mind that she will get where she is going. Also I'm not afraid to use it at highway speeds just incase of ice or slush in the middle or passing lanes. Like I said piece of mind.
Ya OR , could just use 4 x4 instead of having engaging when you aren't ready for it, that's hard to case!
@@MMikeHD3904 yeah but she complains about it turning hard and I don't like going 80 mph in 4 hi so it's my preference and I'm happy with it
Lol! Or piece of mind of not breaking it.
@@urbanmechanic9254 If road conditions are such that you can drive 80mph you do not need 4 wheel.
In North Dakota, we had probably similar weather as to what hit Edmondton, we got a lot of snow over a couple days and it was a couple days until the streets in my hometown in SWND were cleared. We got well around 12 inches of snowfall the first night, or 30cm.
My 99 Silverado has basically the same 4X4 system as the new GMC/Chevrolet pickups have. I believe the 99 Silverado/Sierra was the first year this system was offered with the Auto 4X4 engage. However the 6.2L wasn't available at that time, mine is the 5.3L. It's also an extended cab long box so it may be slightly longer wheel base than this truck.
I was able to get out both days of the storm and my wife and I did make it to work with the pickup, but I had just left it in 4X4 High, I didn't engage Auto 4X4. But being it was as cold as it was, I did start out in 4X4 Low just to maintain slow speeds. When I was out on the streets after driving for a few minutes, I did switch to 4X4 High to complete the drive to work, and we got around just fine. I'd have no concerns about using Auto 4X4 but due to the conditions, I decided to just run 4X4.
We usually don't get a huge amount of snow this early in the season, but sometimes it does happen. I guess it was just our turn this year.
Great explanation of how and when to use the system. Too bad you didn't have some deep snow to drive it through to more accurately demonstrate how to use the system and why depending on conditions.
I am sure I could do a follow up at some point…
@@Donslife Yea, we could have a lot of winter this season yet.
Auto is two wheel when you don’t need it the truck decides based on traction. Feel free to leave it on Auto for the winter. Rest a sure you will be in two wheel more than 90 percent of the time just like your normal.
Read your owners manual. If the roads are packed 4WD high is fine and will save unnecessary wear of the transfer case clutches like in AUTO mode.
I have a 2014 2500HD Duramax, I do not have the auto feature on the T Case. I put it 4H when needed which is not often.
Just got me a new to me Colorado ZR2 and this was very informative.
Auto FWD is helpful for those icy overpasses that catch you off guard especially when pulling a trailer. The wobbling in the front end is the ujoints binding up from the extreme turning angle.
The wobble is from a locked differential. Both wheels are trying to spin at the same speed. The outside tire cannot spin at the same speed as the inside tire though a sharp turn when the diff is locked. Has nothing to do with the u-joints. If this was the case my FWD Prius, and every FWD vehicle would have binding issues with tight turns. Also, it's Auto 4WD not Auto FWD
Great video. I have a 2020 1500 LT that I’m keeping stock and you just confirmed my decision.
you're never too old for doughnuts my friend, also nice touch with the Timmies!
Always use 2H on dry pavement. When the vehicle is engaged in 4wd，the front wheels rotate faster than rear wheels while turning despite the power output is 50:50 on both axels in order to generate a pulling force to maneuver the vehicle through low traction surfaces. If force the vehicle to be driven on good traction surfaces， what happens is the front and rear axels play tug n war against each other with the drive shaft as the rope，and can damage the drive shaft by twisting it as the twisting force generated by the difference in rotation speed of each axel cannot be released on the ground with good traction.
Thank you!
I live in sunny Florida...not a fan of snow, but found myself super jealous of 4 wheel doughnuts in the snow😉
😂 I would miss the snow for that
The last part of this video is the fun part thank you for this info on 4x4 driving 👍
The end was the fun part! 😂 Thank you. Some tidbits of info, all which can be found in the manual too.
What mode you are in does in fact effect your ability to stop as well. It puts drag onto the drivetrain as well as removeing the forward passive drive of the vehicle and also can effect the slip or non slip of the differential case. Depending on what you have.
Yessir!
Good day from Ontario. I had 2013 gm 4 wheel lever manual. Bought 2019 & it has buttons like yours.
That auto is good art corners but on straight away, I think it is fooling you, by staying in 2 drive u are alittle more aware of road conditions. Thanks good video.
This is a great video! I recently got my first truck (2018 Silverado LTZ Z71) and took it out with the recent snow storm in upstate NY. Most of this info regarding the transfer case was unbeknownst to me, but i assumed 4H was for fast speeds and 4L is for low speed situations. Well I was using 4H and turning felt super jerky, truck was also very noisy. Well the roads i were driving on were mostly down to the pavement and there wasn’t much snow/ice. I did some research because i thought something was wrong with the truck.. came across your video and i have to say thanks for a simple informative explanation. I will now just stay in 2wd or use auto when coming across these situations. I was using 4H when the roads had too much transaction, causing a bit of a binding in the drivetrain.
Glad there was some useful info there! Auto is okay too if you need to leave it on for intermittent periods throughout the day. You just wouldn’t want to leave it on when 2wd would be perfectly safe
@@Donslife 🤙🏼right on man good stuff
@@Donslife Question man!!!' How fast can u go in auto!?!!?????
As fast as your tires are rated. Going highway speeds is not an issue
I drove up in Canada in the winter down hills. Wheels, wheels my friends matter most then the transfer case. 4x4 helps going up hills.
Take care ya hosers!
Thank you very much for such an informative video. I have a 2020 1 ton GMC Denali that i bought when i lived in So. Calif. Asked the salesman to explain the whens and when nots about 4wd and auto modes. He wasn't sure because it never snows where we lived at the beach. Now I live in northern Utah and we recently had our first snow of the season. I put it in 4H to get out of my driveway and drove around town like that. Thanks to your excellent video I will now use the AUTO function . Great job!!!
I have an 07 Chevy Silverado half ton. It has the auto. I love it and use it regularly here in Colorado.
Were I live in GA we get lot of heavey rains, driving in 4 HI kept from being jerked when going through deeper areas of water
You have helped me out a lot , I just bought a 2002 Chevy avalanche and it has the Auto 4 wheel drive and the 4 high and the 4 low and it also has the 2 high and I was wondering when I should shift into the 4 high , you have helped me out a lot so I really do appreciate your videos and your doing such a great job 👍👍👍👍 Thank you very much 👍👍👍👍
Thank you so much! Glad you found the video helpful
Here in Iowa we get huge drifts from the constant wind. The roads may be clear but you randomly run into drifts up to 5 feet deep. I stay in 4 high so I can speed up and bust through them
Very helpful video. I too live in a very cold & icy place but in the mountains. 2 questions-
• Is there a limit to your speed when switching from 2WD to 4A? How about when switching from 4A to 4H & back?
• Is there a speed you should not be driving over when in 4H or 4L? I’m thinking about steep icy inclines or icy mountain passes with a steep grade in blizzard conditions.
Thanks for watching the video! You can double check the owner's manual but shifting from 2WD to Auto4WD or 4High is usually recommended below speeds of 60mph. I also make sure I am driving in a straight line during any changes is settings. 4High doesn't have a set speed once you are in that setting, but I would recommend no more than the speed limit. As for 4Low, it is usually to be kept under 10mph.
Don, I enjoyed your video. One thing I would clarify. You mentioned 4L having "better traction", while driving through deep snow. That is a myth, obviously gear selection cannot affect tire friction with the road surface, and in fact there are some times when selecting a higher gear can decrease the chance of tires slipping. If you are trying to climb a hill, get going from a start, etc., with very limited traction (lots of power and torque are not needed), the key is to apply very smooth and consistent power to each wheel. Internal combustion engines do not produce very smooth and consistent power, think more like impact gun than electric motor. However, the fluid coupling of the torque converter can help smooth that power out. If the vehicle is in 4H you will have to use more engine RPM to initiate movement and with that higher RPM more smoothing will take place. Also, as torque spikes come though the transmission and into the transfer case/driveline they will be less likely to break tire traction in the higher range.
Try this the next time you have to get started on a very steep and slippery hill. Put it in 4L and slowly and gently apply throttle until movement is achieved, test how easy it is to not break traction and get moving. Then switch to 4H and try again, slow and smooth throttle pressure. It will be much easier to control in 4H and you will be able to get speed more quickly without breaking traction. As long as you did not overheat the trans fluid you didn't hurt anything or cause wear, you just made better use of your torque converter.
The same thing can be achieved in a manual transmission to a lesser degree, use 2nd or third to limit torque spikes. Often better than 1st at getting un-stuck. Maybe not the best to do to a manual trans clutch, but if a gentle start in 2nd gets you out when 1st would not, hopefully not a significant clutch wear event.
In addition, I tell drivers to be careful with those "4 auto" settings because whatever clutch or engagement device is being used to connect the front axle when rear axle slippage is detected is subject to wear or breakage. Auto 4WD is better than 4H or 4L for driving at speed around curves on slippery surfaces, because those 4H and 4L settings force the front and rear driveshafts to turn the same speed, even though the front tires travel further on a curve. That results in forced tire slippage in 4H and 4L on curves (the choppy turning you demonstrated), and could cause a vehicle to loose control on a curve in 4H or 4L that it could have successfully negotiated at the same speed in 4 auto or 2WD. But, if 4 auto is being used and the rear driveshaft very quickly increases speed (heavy throttle on ice) and then the front axle is engaged a lot of force is put on those engaging components to very quickly bring the front axle up to the same speed (possible big bang and broken parts).
Thank Russ. It was a tricky video to make while keeping it accessible to people that have never used these options, but have had them for some time. I agree with your statements too. It reminded all the times in my youth getting started in deep snow with a manual tran. Depending on the vehicle, sometimes a 3rd gear start was the smoothest way to get out.
This amount of snow and ice is considered summer up on the North where I live in. People usually roam around with little clothings on a 120hp or less 2wd vehicle if the snow is only this much. We only choose to drive less than 30Mph when there's a Blizzard going over us for 2 days or more and there's like 3 feet or more snow on the road. 4wd is only reserved when you get buried with snow in the parking lot.
Great advice and helpful information 😊
I used to own an 03 Tahoe and the only time I ever had to put it in 4x4 was when I was playing in the mud or deep snow for fun. Otherwise 2wd was all I ever needed to get around in winter. The Goodyear Duratrac tires definitely helped too lol
Did you have the factory G80 locker in it ?
@@Terk131 I have no idea. I bought the truck used and the seller didn’t know much about it. It had auto 4wd and a locking rear diff that I can tell you.
You can probably google a free VIN search and find out some of those details. The G80 Locker has been around for quite awhile and does work pretty good.
@@Donslife I sold it 4 years ago cause it was developing some electrical gremlins. Rear heater fan would randomly turn on by itself, drivers door would go dead (nothing worked) randomly. The list goes on. I got rid of it before it became a lawn ornament lol
Fair enough
One thing to note. Most trucks even new one don't have auto mode. It's just 2 hi 4 hi N or 4 lo. If my wheels were spinning on normal acceleration. I put it in 4 hi but where I live there are steep hills and mountain passes to drive through. I usually only used 4 lo off road and not very often even then. The last time I used 4 lo was to pull out fence posts on a property we bought. The time before that was to pull my friends large trailer from behind his house where he stored it off season. The grass was wet and his truck was only 2 wheel drive. I'm actually to the point I want to find a 4 wheel drive truck from the late 60s to early 70s and fix it up. What little electronics it has are up high and wading through streams I don't need to worry.
Lots of variety out there for sure
Watching this on 2x playback speed is absolutely terrifying.
As others mentioned, 4 Low is not for snow or mud. It's generally for terrain that is so rough that you cannot go slow enough in high range to avoid bouncing all over the place. Most people never need to worry about using it.
Last January we had a big snow storm (3ft in 10 hours). We already had 2 ft on the ground, so I had to dig down to open the door on my pickup.
I put it in 4 low and literally pushed the snow with my bumper and tailgate to get out so I could wait for the road to be plowed to get to town.
I was surprised that my Ranger was able to do it.
But I suppose that’s why we’re on our 4th Ranger. Their just good durable mid sized pickup’s.
That was the only time I had it in 4low
I loved my Ranger too. Too small for my lifestyle now
Very good informative video! Thanks for taking the time
Glad it was helpful and thanks for watching it
Our pickup is a 2011 and it doesn’t have automatic 4WD. I have to manually put it in 4WD or manually take it out. Thankfully it’s just a switch on the dashboard.
I do miss manually locking front hubs. They tend to last longer than auto locking.
Please correct me if I'm wrong but ... my understanding is that "auto" 4WD relies on the vehicle's computer to detect slippage before it engages. It is useful at low-speed applications like parking lots, local side streets and driveways. If you're traveling at highway speeds using auto mode, you need to remember that "auto" 4WD is intermittent by design and may not engage quickly enough to give you the traction you need, when you need it.
In contrast, if you select 4WD Hi mode for highway speeds, it is engaged at all times ... until you deliberately disengage it. That makes it more predictable because you don't have to wait for the computer to detect slippage before it kicks in (which, depending on the conditions, may be too late). 4W high ultimately provides full-time control at higher speeds. One caveat is, that if you're needing four-wheel high at higher speeds, then chances are the conditions are poor enough that you probably wouldn't be traveling at the full speed limit anyway. At least you shouldn't be.
Just remember, 4 wheel drive does not mean4 wheel stop!
Very helpful 💯❤️ I purchased a 2013 Chevy Silverado 1500 4x4 with no owners manual unfortunately. I knew my 2000 Ford Expo like the back of my hand but this Chevy has tons of bells n whistles I'm not familiar with! This was helpful for this old school locking hubs kinda girl!
Very glad you found the video! My last truck was a 2013 Sierra Denali
Look on ebay for a owners manual 😀
This is an excellent video, I’m very familiar with the four-wheel-drive selections, especially in the GMC family. Very good explanation in the different 4-wheel Drive settings.
I don’t know why I wasted 20 min as I already know this stuff, But that’s a testament to your ability to present the information well. Great video for folks who don’t know these things and nice truck. Cheers!
New truck owner here, thanks for the tips brother
Have been driving OH/PA winters for almost 40yrs. The ONLY times i use 4wd in my trucks over the years were at stop lights on inclines. Maybe 4-5-6 times a winter. Maybe another 5-6 times driving during/after major snowstorms. And really probably haven't needed it the last handful of winters around here. Not like winters back in the 70's into the 80s.
Great video. Found it very informative I bought a 2018 sierra n the 4 wheel drive is something I was unsure about. I heard you need to stop and put it in park to engage 4 high or low.
Thank you! You need to stop and put it in neutral for 4 Low.
Excellent video. I live here in New Zealand, slightly different from Canada. Agree with you with the driving experience. Through winter in the south island here is very similar to Canada's winter. We do have a number of un tarsealed (gravel) roads in country areas which would suit 4 auto in summer. Possibly 4 high Through winter. I personally would leave vehicle in 4 auto for new or learner drivers through winter.
Hello New Zealand! Visited your paradise in early 2000. Took me a while to get used to wrong side drive, and the one at a time single lane bridges were totally new to me. Nicest people I've ever met, in the most beautiful country in the world. Rotorua is amazing.
@@reallythough4591 rotorua is a stink hole. A typical tourist trap. Nz is ok. Damed expensive for living, especially food, housing and power
@@kenbearsley8322 being the most volcanically active place in the world(at the time) the sulfur smell was pungent. I rented a car and did both islands. I don't remember the name of the hotel, but I remember a free drink every night at the pig and whistle. I met a couple from Norway on the first stop of my round the globe trip, in Tahiti, then picked them up again in NZ. I enjoyed every aspect of the country thoroughly, including Rotorua. Paddled down the river thru Christchurch, and rented a house on the beach in Wellington for a couple nights. The world cup yacht race was going on. NZ is spectacular. One of my fondest memories.
I put some weight in the bed of my 2wd pick up truck and get around very good on paved or maintained gravel or dirt roads during winter conditions. However I’m very conservative and don’t attempt to do anything stupid. There are so many people that think they must have four-wheel-drive. I owned four-wheel-drive vehicles before and rarely ever engaged the transfer case. I found myself engaging the transfer case just to keep everything lubricated.
My daily work vehicle is a 93 ranger 2wd. I have studded winter tires and have never got stuck in the 13 years I've had it. With a few concrete blocks and my snowblower in the bed it's impressive! It does have limited slip which does help! I leave my 4+4 pavement princess in the garage to stay salt free!!! Lol
Thank don very informative I have a 2021 slt with all the bells and whistles. I keep it in 2 wheel Drive. But you just gave me some good advice. All your videos and upgrades are very helpful. I wish I could give you a 💯
Actually 4 high has been proven to shorten you stopping distance in slippery conditions because unlike 4 auto 4 high still locks your axles together when braking, evening out the braking distribution
Absolutely because when you're slowing down you're not just swollen using the back wheels. Just like in my Camaro when I was young I downshift too fast let the clutch out and lock up the back wheels
Well done. Good video. Just remember to turn off Auto when the pavement dries up. An old mechanic friend from a Chevy dealership reminded me that Auto is not AWD. When Auto is on the truck is actually in 4WD and the transaxles will wear prematurely on dry pavement.
