Active Distance Assist DISTRONIC
Function of Active Distance Assist
DISTRONIC
Active Distance Assist DISTRONIC maintains the
set speed on free-flowing roads. If vehicles in
front are detected, the set distance is main‐
tained, if necessary, until the vehicle comes to a
halt. The vehicle accelerates or brakes depend‐
ing on the distance to the vehicle in front and
the set speed. The speed and distance to the
vehicle in front are set and saved on the steering
wheel on vehicles without the Driving Assistance
Package, in the range between 15 mph
(20 km/h) and 120 mph (200 km/h) and, on
vehicles with the Driving Assistance Package, in
the range between 15 mph (20 km/h) and
130 mph (210 km/h).
