Active Lane Keep Assist Permanently Off But Still On?
When I start up my car, I always disable Active Brake Assist and Attention Assist. When I first got the car, I disabled all the other Driver Assist features (Speed Assist, Lane Change Assist, and Active Blind Spot Assist). I was reading that by default, all Driver Assist features turn on every time he car is restarted. However those 3 features always remain checked Off whenever I start my car. Or at least that’s what it displays on the screen.
Even though Active Lane Change Assist remains in the Off position upon startup, it’s very much active and alive. It will routinely swerve my car back into my lane if I fail to signal while overtaking another car, which has resulted in a few close calls. It’ll also swerve me back into my lane if I exit the freeway without signaling.
Needless to say, i find it extremely annoying. I don’t get what the point of having an “Off” option if it always stays on? If I had the opportunity of building my car to spec, I definitely would’ve scratched this worthless $1700 option off the build sheet!
This is what I see upon every startup. 3 Driver Assist features are in the Off position.

I was told by my SA it’s not normal for the lane assist to be in the off position by default as it has to be manually turned off every time the car is started. So it likely needs a Driver Assist software reset since it seems to be stuck in the On position at all times.

There are enough people changing lanes w/o indicating. Please don't be one of them. However, to your issue, you are confusing two different systems. You are confusing Active Lane Keeping Assist w/ Active Lane Changing Assist. They are two entirely different systems. The latter is what you turned off, and what it does if on is with DISTRONIC and Active Steering Assist active it will automatically change lanes by simply turning on your blinker. If the adjacent lane is free, it will change lanes for you.
Active Lane Keeping Assist on the other hand is controlled with the dedicated button to the left of the steering wheel and it stays off once you turn it off. It's on if the LED in the button is illuminated, otherwise it's off.
The buttons are a bit different in the PFL vs FL, and depend on the car's equipment, but the first two control the Active Steering Assist (first button) and Active Lane Keeping Assist (second button).

Thanks superswiss! I literally just figured this out last night when I decided to look at the list of all the features under the Driver Assist package. I had no idea there are 2 lane assist features. I realized only Active Lane Changing Assist is controlled by the Vehicle settings on the screen. I found the other buttons to the left of the steering wheel and turned off Active Lane Keep Assist. I also turned off the Steering Assist button. Thankfully they stay off upon restart as well. It’s so much better now, I can finally drive the car without an AI nanny interfering. I get some folks like the Driver Assist options but it’s just not for me. I’ve never needed them in any of my cars and don’t need them in the C63.
As far as signaling, I do always signal in heavy traffic. If traffic is on the lighter side, then I’ll admit I don’t always signal. It’s the way I’ve always driven, and driving habits aren’t easy to change after 30+ years behind the wheel. Thankfully, I’ve never had an at-fault accident and zero traffic tickets in the past 17 of those 30 years. Knock on wood!

Reviving 6 month old thread. I'm looking at buying a particular 2017 C43 and it has the driver assist package with all the electronic nannies. Can these be completely disabled so the car can be appropriately driven on track or autocross without electronic intervention? I read in a GTS forum that they sometimes cover sensors with tape while on track to prevent Brake Assist from triggering. I found the below thread, but I'm not sure if these details will apply to a '17 C43. Thanks!

To bad that they don't make a guide that one could read to find out how all of the systems in our cars work, they could call it an "Operator's Manual".

@JRHolt Hi. Thanks for the attitude/sarcasm, but I'm asking because I've read in these and other forums several times that some safety features are still active even though they are turned off. So, I was hoping people with on-track experience could comment on what really happens with a pre-FL C43.

I’ve done a driver’s day with MB where they were featuring all their safety systems and latest cars (really trying to get us to buy).
All the switchable items on your dash are that. You can set them as you prefer from the available list. What can not be fully disabled is the stability control system (ESP) - Not sure about your car but the ESP button on most cars will “reduce” the ESP but it is never fully off.
We drove sone C-Class cars on a skid pan in 3 configurations
1) ESP on (button on dash)
2) ESP off (button on dash)
3) ESP fully disabled by a technician.
It is an education as to how much the car is helping the driver. 1, 2 & 3 are very different with 3 making the car almost undriveable on a skid pan.
