Parking brake
The concept
Your vehicle is equipped with an electrome‐
chanical parking brake that can be set and re‐
leased by using a button.
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 electromechanical
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 button. The parking brake is set. The indicator lamp in the instrument
cluster and the LED on the button light
up red. The parking brake is set.
Indicator lamp 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 button for an ex‐
tended period: the vehicle brakes forcefully
while the button is being pulled.
The indicator lamp in the instrument
cluster lights up red, a sound is issued
and the brake lights light up.

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 example,
cannot start the engine or release the parking
brake.◀

Declaration according to NHTSA/
FMVSS 138 Tire Pressure Monitoring
Systems
Each tire, including the spare (if provided)
should be checked monthly when cold and in‐
flated to the inflation pressure recommended by
the vehicle manufacturer on the vehicle placard
or tire inflation pressure label (If your vehicle has
tires of a different size than the size indicated on
the vehicle placard or tire inflation pressure la‐
bel, you should determine the proper tire infla‐
tion pressure for those tires.).
As an added safety feature, your vehicle has
been equipped with a tire pressure monitoring
system (TPMS) that illuminates a low tire pres‐
sure telltale when one or more of your tires is
significantly under-inflated. Accordingly, when
the low tire pressure telltale illuminates, you
should stop and check your tires as soon as
possible, and inflate them to the proper pres‐
sure. Driving on a significantly under-inflated tire
causes the tire to overheat and can lead to tire
failure. Under-inflation also reduces fuel effi‐
ciency and tire tread life, and may affect the ve‐
hicle's handling and stopping ability.
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's re‐
sponsibility to maintain correct tire pressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire pres‐
sure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when
the system is not operating properly. The TPMS
malfunction indicator is combined with the low
tire pressure telltale. When the system detects
a malfunction, the telltale will flash for approxi‐
mately one minute and then remain continu‐
ously illuminated. This sequence will continue
upon subsequent vehicle start-ups as long as
the malfunction exists. When the malfunction
indicator is illuminated, the system may not be
able to detect or signal low tire pressure as in‐
tended. TPMS malfunctions may occur for a va‐
riety of reasons, including the installation of re‐
placement or alternate tires or wheels on the
vehicle that prevent the TPMS from functioning
properly. Always check the TPMS malfunction
telltale after replacing one or more tires or
wheels on your vehicle to ensure that the re‐
placement or alternate tires and wheels allow
the TPMS to continue to function properly.
Brake force display
The concept▷During normal brake application, the brake
lamps light up.▷During heavy brake application, the turn sig‐
nals light up in addition.
The brake force display is not activated if the
turn signal function is switched on.

Driving stability control systemsVehicle equipment
This 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 sys‐
tems.
Antilock Brake System ABS
ABS prevents locking of the wheels during brak‐
ing.
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 shortest
possible braking distance during full braking.
This system utilizes all of the benefits provided
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. Subject
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 82.
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 81Driving stability control systemsControls81
