If adaptive cruise control (ACC) is active, the engine
starts automatically if the vehicle in front drives off.
Reaction after leaving the vehicle
After leaving the vehicle when the engine has stop-
ped automatically (driver's seat belt unfastened,
driver's door open and brake pedal released), the
engine will not start automatically. Additionally, in
operating modes D, R or M:
– The electric parking brake is engaged.
– The transmission parking lock P is engaged.
The vehicle can still be moved with the driver's door
open and the driver's seat belt unfastened by re-
leasing the electric parking brake manually. In this
case, the parking brake remains released and the
selected transmission range is still engaged.
If the parking brake is released in operating mode D,
R or M, or if operating mode D, R or M is selected
while the brake pedal is pressed, the engine starts
again.
Auto Start Stop mode is resumed if one of the fol-
lowing conditions is detected within 30 seconds of
leaving the vehicle:
– The brake pedal is pressed and either the driver's
door is additionally closed or the driver's seat belt
fastened.
– or –
The driver's door is closed and the driver's seat
belt is then fastened.
– or –
The accelerator pedal is pressed with the driver's
door closed and the driver's seat belt fastened.
Switching off the Auto Start Stop function within 30
seconds after leaving the vehicle results in an engine
start only after the driver's door has been closed and
the seat belt has been fastened. If none of these
requirements are met, the engine has to be started
manually 30 seconds after leaving the vehicle. A
message prompting you to start the engine manually
appears on the instrument cluster.
