Parking brake The concept
Your vehicle is equipped with an electrome‐
chanical parking brake that can be set and re‐
leased by using a switch.
The parking brake is primarily used to prevent
the vehicle from rolling when it is parked.
When the vehicle is stationary, the parking
brake acts on the rear wheels via an electro‐
mechanical mechanism. When the vehicle is
rolling or being driven, the parking brake acts
on the disc brakes of the front and rear wheels
via the hydraulic brake system.
Setting
Pull the switch. The parking brake is set. The indicator lamp in the instrument
cluster and the LED on the switch light
up red. The parking brake is set.
Indicator light in Canadian models.
To set the parking brake, the remote control
does not need to be in the ignition lock.
While driving
If exceptional circumstances should make it
necessary to engage the parking brake while
the vehicle is in motion, pull the switch for an
extended period: the vehicle brakes forcefully
while the switch is being pulled.
The indicator lamp in the instrument
cluster lights up red, a sound is issued
and the brake lights light up.
Indicator light in Canadian models.
When the vehicle is braked almost to a halt, ap‐
prox. 2 mph/3 km/h, the parking brake remains set.
Releasing Take the remote control with you
Take the remote control with you when
leaving the vehicle so that children, for exam‐
ple, cannot start the engine or release the
parking brake.◀
The parking brake can only be released while
the ignition is switched on or the engine is run‐
ning.Seite 61DrivingControls61
