Distronic Sensitivity

The one situation that makes me feel uncomfortable in my C is as follows....

When I have Distronic engaged, and when I approach a car (from behind) that is travelling much slower than me, my car waits for what seems like a long time before braking, and at that point it brakes quite hard. If I were driving, I would have started braking quite a bit sooner but more gently.

Has anyone else felt uncomfortable under the same circumstances?

I have experienced this also but for those situations i just brake myself. It helps when you increase the distance between you and the car in front of you by rotating the end of the stick.
You should still stay alert and in control of your car.

Maybe the autopilot was busy thinking of something else at the time




Sometimes it certainly waits until the last minute to slam on the anchors - other times its completely normal. Keep in mind though, the sensitivity seems to also be variable in reference to:
a) the distance setting you have applied; and
b) the Agility mode currently set.

It's definitely more aggressive driving in Sport or Sport+.

I have a 2016 C300 4Wheel drive, and like you I feel very uncomfortable when approaching a vehicle from behind as it seems to brake at the last minute and then very hard. Definitely not the way I drive. There must be other complaints about this feature maybe MB has a fix?

I have a service coming up in about a month. I'm going to ask if there's a software change to address this.

What distance do you have set? Minimum distance setting might cause that. Try rotating the stalk end to something over 100ft and see if that works better.

I have mine set at 100 ft and it works great for me.

But you are driving. I'm confused. You let it run right up another cars *** and wait for it to brake? Why?
