Your vehicle pulls away and adapts its
speed to that of the vehicle in front.
If there is no vehicle in front, DISTRONIC
PLUS operates in the same way as cruise
control.
If DISTRONIC PLUS detects that the vehicle
in front has slowed down, it brakes your
vehicle. In this way, the distance you have
selected is maintained.
If DISTRONIC PLUS detects a faster-moving
vehicle in front, it increases the driving speed.
However, the vehicle is only accelerated up
to the speed you have stored.
If you depress the brake, DISTRONIC PLUS is
deactivated unless your vehicle is stationary.
