▷LED goes out: the Auto Start/Stop function
is activated.
Automatic deactivation
In certain situations, the Auto Start/Stop func‐
tion is deactivated automatically in the interest
of safety, for example if the driver's absence is
detected.
Malfunction The automatic engine Start/Stop
function no longer switches of the
engine automatically. The indicator
lamp lights up. A message appears on the
Control Display.It is possible to continue driv‐
ing. Have the system checked.
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

Driving stability control systemsVehicle equipmentThis chapter describes all series equipment as
well as country-specific and special equipment
offered for this model series. Therefore, it also
describes equipment that may not be found in
your vehicle, for instance due to the selected
special equipment or the country version. This
also applies to safety-related functions and
systems.
When using the features and systems descri‐
bed here, adhere to local regulations.
Antilock Brake System ABS ABS prevents locking of the wheels during
braking.
The vehicle remains steerable even during full
brake applications, thus increasing active
safety.
ABS is operational every time you start the en‐
gine.
Electronic brake-force
distribution
The system controls the brake pressure in the
rear wheels to ensure stable braking behavior.
Dynamic Brake Control DBC
When you apply the brakes rapidly, this system automatically produces the maximum braking
force boost. It thus helps to achieve the short‐
est possible braking distance during full brak‐
ing. This system utilizes all of the benefits pro‐
vided by ABS.
Do not reduce the pressure on the brake pedal
for the duration of the full braking.Dynamic Stability Control
DSC
The concept DSC prevents traction loss in the driving
wheels when driving away and accelerating.
DSC also recognizes unstable vehicle condi‐
tions, such as fishtailing or nose-diving. Sub‐
ject to physical limits, DSC helps to keep the
vehicle on a steady course by reducing engine
speed and by applying brakes to the individual
wheels.
Adjust your driving style to the situation
An appropriate driving style is always the
responsibility of the driver.
The laws of physics cannot be repealed, even
with DSC.
Therefore, do not reduce the additional safety
margin by driving in a risky manner.◀
Activating/deactivating DSC DSC can be deactivated/activated via the DSC
OFF program of the Dynamic Driving Control,
refer to page 102.
For better control The DSC indicator lamp flashes: DSC
is controlling the drive forces and brake
forces.
The DSC indicator lamp lights up: DSC has
failed.Seite 101Driving stability control systemsControls101
