ated, activated or deactivated by a passenger

celled and the vehicle can start moving if:
R DISTRONIC PLUS is deactivated using the
cruise control lever.
R you accelerate.

interruption in the power supply, e.g. bat-
tery failure.

partment, the battery or the fuses are tam-
pered with.
R the battery is disconnected.
If you wish to leave the vehicle or park it,
deactivate DISTRONIC PLUS and secure the
vehicle against rolling away.

in front is stopping, it brakes your vehicle until
it is stationary.
Once your vehicle is stationary, it remains
stationary and you do not need to depress the
brake.

tance, your vehicle will come to a standstill
at a sufficient distance behind the vehicle
in front. The specified minimum distance is
set using the control on the cruise control
