Active Distance Assist DISTRONIC
General notes
Active Distance Assist DISTRONIC regulates
the speed and automatically helps you main-
tain the distance from the vehicle detected in
front. Vehicles are detected with the aid of the
radar sensor system. Active Distance Assist
DISTRONIC brakes automatically to avoid
exceeding the set speed or to maintain the
designated distance from the vehicle in front.
If Active Distance Assist DISTRONIC detects
that there is a risk of a collision with the vehi-
