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.
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.
Brake assistantWhen you apply the brakes rapidly, this systemautomatically 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The laws of physics cannot be repealed, even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.
Do not reduce the additional safety margin
with a risky driving style, as otherwise there is
a risk of an accident.◀
Deactivating DSC: DSC OFF When DSC is deactivated, driving stability is
reduced during acceleration and when driving
in bends.
To increase vehicle stability, activate DSC
again as soon as possible.

Press and hold the button, but not lon‐
ger than approx. 10 seconds, until the
indicator lamp for DSC lights up in the instru‐
ment cluster and DSC OFF is displayed. DTC
Dynamic Traction Control and DSC are deacti‐
vated together.
In the interest of better forward momentum,
brake intervention is performed in the manner
of a differential lock when the drive wheels spin
quickly even if DSC is deactivated.
Activating DSC Press the button.
DSC OFF and the indicator lamp in the
instrument cluster go out.
For better control The indicator lamp flashes: DSC con‐
trols the drive forces and brake forces.
The indicator lamp lights up: DSC and
DTC has failed.
DSC deactivated: The indicator lamp lights up and
DSC OFF appears in the instrument
cluster.
DSC and DTC deactivated.
Dynamic Traction Control
DTC
The concept The DTC system is a version of the DSC in
which forward momentum is optimized.
The system ensures maximum forward mo‐
mentum on special road conditions, e.g., unp‐
lowed snowy roads, but driving stability is lim‐
ited.
It is therefore necessary to drive with appropri‐
ate caution.
You may find it useful to briefly activate DTC
under the following special circumstances:▷When driving in sand, on snowy inclines, in
slush, or on unplowed, snow-covered road
surfaces▷When rocking a vehicle free or starting off
in deep snow, sand, or on loose ground▷When driving with snow chains.
Deactivating/activating DTC Dynamic
Traction Control
Activating the Dynamic Traction Control DTC
provides maximum traction on loose ground.
Driving stability is limited during acceleration
and when driving in bends.
Activating DTC
Press the button.
TRACTION is displayed in the instru‐
ment cluster and the indicator lamp for
DSC OFF lights up.

DTC is activated.
Performance Control
Performance Control enhances the agility of
your vehicle. To enhance performance during
sporty driving, the rear wheel on the inside of
the curve is braked while the resulting braking
effect is largely compensated by engine inter‐
vention.
xDrivexDrive is the all-wheel-drive system of your ve‐
hicle. The combined effects of xDrive and DSC
further optimize the traction and dynamic driv‐
ing characteristics. The 4-wheel drive system
xDrive variably distributes the drive forces to
the front and rear axle depending on the driv‐
ing situation and prevailing road conditions.
Hill Descent Control HDC
The concept HDC is a downhill driving assistant that auto‐
matically controls vehicle speed on steep
downhill gradients. Without requiring brake ap‐
plication, the vehicle moves at slightly more
than twice walking speed.
You can activate the Hill Descent Control at
speeds below approx. 22 mph/35 km/h. When
driving downhill at below approx.
22 mph/35 km/h, the vehicle reduces its speed
to approx. twice walking speed and keeps it
constant.
While you are actively braking, the system is
on standby. The system does not brake the
vehicle during this time.
Increasing or reducing speed
The speed can be changed in the range from
roughly twice walking speed to approx.
15 mph/25 km/h by pressing the accelerator or
brake pedal lightly.
A target speed within the same range can be
specified using the lever of the cruise control.1Increasing speed2Decreasing speedSeite 99Driving stability control systemsControls99

Malfunction
If the HDC display goes out during HDC opera‐
tion or is not displayed: HDC is not available
due to high brake temperatures or DSC has
failed.
Drive-off assistant
This system supports driving away on gradi‐
ents. The handbrake is not required.1.Hold the vehicle in place with the foot
brake.2.Release the foot brake and drive away
without delay.
Depending on the vehicle load, the vehicle may
roll back slightly.
Driving off without delay
After releasing the foot brake, start driv‐
ing without delay, since the drive-off assistant
will not hold the vehicle in place for more than
approx. 2 seconds and the vehicle will begin
rolling back.◀
Servotronic The conceptThe Servotronic varies the steering force re‐
quired to turn the wheels depending on the
speed at which you are driving.
Power steering provides strong support at low
speeds, which means that less effort is needed
to turn the wheels. Power steering support
lessens as your speed increases.
Malfunction The warning lamp lights up.A mes‐
sage appears on the Control Display.
Servotronic is malfunctioning or has
failed. Have the system checked as soon as
possible.

tion, e.g., if the vehicle interior is hot from the
sun.
Draft-free ventilation
Adjust the vent to let the air flow past you.
Microfilter/activated-charcoal filter
The microfilter traps dust and pollen in the in‐
coming air.
The activated-charcoal filter removes gaseous
pollutants from the outside air that enters the
vehicle.
Your service center replaces this combined fil‐
ter during routine maintenance.
Parked-car ventilation The conceptThe parked-car ventilation blows air into the
passenger compartment to lower interior tem‐
peratures.
The system can be switched on and off at any
external temperature, either directly or by us‐
ing a preset switch-on time. It remains
switched on for 30 minutes.
Since the system uses a substantial amount of
electrical current, refrain from activating it
twice in succession without allowing the bat‐
tery to be recharged in normal operation be‐
tween use.
