- How can a vehicle help prepare a driver and passengers for an accident just moments before it happens? Buckle up - the "Veritasium meets Mercedes-Benz" series is here to show you the latest in auto innovation. Subscribe to the channel so you get notified of the next episode here:
The Mercedes-Benz PRE-SAFE® system is used in conjunction with both the Mercedes-Benz Active Brake Assist and the Electronic Stability Programme ESP®, both of which are car safety features that detect dangerous situations via advanced sensors.
As soon as certain hazardous conditions are detected, PRE-SAFE® activates a number of safety features. These include electrical reversible belt tensioners, the PRE-SAFE® seat positioning function, and the automatic closing of windows and the sunroof. The PRE-SAFE® seatbelt element ensures that both the driver and the front passenger are fixed in their seats while the positioning function places the passenger in a more favourable position for a potential collision. In the new Mercedes-Benz S-Class, those features are even available as an option for the outboard rear seats.
The Mercedes-Benz PRE-SAFE® system utilizes sensing technology of active safety systems in order to identify situations that could end in a crash. However, if the crash can be avoided, the preventive measures will be deactivated, leaving you ready to continue your ride.
Thanks for Watching!

Both of my GLSs have saved me in a couple of accidents!
This was GREAT today it’s been non stop raining in Houston tx. This message came up and turned off my car at the light. 😐 thought car was messing up. Glad I watched this and can now share with my mom what we just experienced. Love Mercedes for safety. 🥰
Can you explain why your car was turned off?
@@Nightbird. sure! I called a dealership and they said it’s a “safe” feature. If the car feels that there could be an accident coming up it will turn off. In my experience that could’ve been dangerous. Later my car kept doing it when I slowed down at lights then another dealership said yes the first answer was right but that the “extra” battery that the car has was now dying. I needed it replaced and possibly the power one too. Usually they go out at same time. He said you can use the car with the small one not functioning because that’s just for the sensors, pre safe options, eco ect. So he said to turn off the eco light to turn off all “extra”battery options from wanting to work and wouldn’t turn car off when I slowed down. That did do the trick for now until I get it replaced just have to be careful. Hope that helps. 😊
@@blessedbythebest1003 Thank you so much for the information! That is really important to know so that you don't panic and think the worst. I'm currently shopping for a 2017 S550 4MATIC (I don't like the changes they made in 2018) and I'm finding it hard to find a model that has all the safety features as many people saved a little money by not getting them..which really surprises me because safety is EVERYTHING to me to protect my family. I hope you get the battery replacement soon to keep you safe and hopefully that service is under warranty because the MB dealership charges too much for any type of service..which is why I use an independent MB mechanic to fix anything on my older S Class I have now. Take care and thanks again! 😉
@@Nightbird. no problem and good luck!
Safety is everything!
@@blessedbythebest1003 Thanks, you too and Happy New Year!
Hi please help, my 2015 A200 CDI is giving me a warning message that says "PRE SAFE MALFUNCTION" what do I do.. Thank you
.. oh I forgot to ask, why does it switch off the engine when I stop at the stop sign or traffic lights.. lastly, I'd like to know why the speedometer goes on and off when I'm driving... I'd really appreciate your response, thank you.
It automatically shuts off the engine when the vehicle is at rest to cut fuel use and eliminate idle emissions. It then restarts the engine automatically when the driver lifts off the brake or presses the gas pedal.
@@pcray9011 yes but it switches off completely (including media player, Bluetooth, not idling)..y is dat happening
@@lady-leguses0315 Bruh, your battery or alternator may be bad. It has been one year. Did you fix it and what was it?
Innovation that lexus can NEVER compete with
When I drive in London with my 2013 CL500 at some point in traffic all the safety systems fail all together. After some driving and restarting the car, all the messages are gone, back to normal. One of the possible causes according to the manual is:
-the radar sensor system is temporarily inoperative, e.g. due to electromagnetic radiation emitted by nearby TV or radio stations or other sources of electromagnetic radiation.
Do you think this is due to the new 5G poles we have in London? It fails only in one specific area in London. Never when driving up the motorway away from the big city.....
Pre-safe is a waste of time 😁if the system is so complicated that MB will send a German engineer to your dealership and take weeks to tell you nothing found,
It's all great until the pre-safe inoperative warning comes on and it costs thousands to fix
Omg i have it on ,after i runa over a dog,what should i do
If you find an independent MB mechanic the cost is much less than the dealership. All of these modern safety systems are expensive to fix but worth it when they save your life.
@@Nightbird. I am an independent MB shop. More and more systems are either TRP theft related parts which I cannot buy or will need programming which I not able to do. I wouldn't own an MB after about 2010 and never will. They used to make great cars and they were safer than the average statistic for their respective model year
@@bicylindrico I currently have a W126 which I love..but I need a newer S Class with the Pre-Safe Plus and Active Brake Assist features..because the area that I live in has a lot of bad drivers who will brake right in front of you and it's very hard to stop in time or notice this until it is too late. Even though I know you are right that it costs a lot of money to repair these vehicles..I feel I have no choice but to purchase one to protect my family..so I am currently shopping for a 2017 S Class. I was going to purchase a Lexus..but their safety features are not as good as MB even though they are more reliable vehicles.
On balance, your safety is more important than possible cost of repairs for the Pre Safe system.
Lol, Veritasium guy!!
So if my windows are down and my hair is blowing out the window when presafe kicks in I'll end up being bald
stopped working after battery drained, need to pay extra money to reset, just because battery drained
won't buy German car again
BS system, I prefer to control my car not the cart to control me...
