Driving stability control systemsVehicle equipment
All standard, country-specific and optional
equipment that is offered in the model series is
described in this chapter. Therefore, equipment
is also described that is not available in a vehicle,
e. g., because of the selected optional equip‐
ment or country variant. This also applies for
safety-related functions and systems.
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.
Brake assistant
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.
Drive-off assistant
This system supports driving away on gradients.
The parking brake is not required.1.Hold the vehicle in place with the foot brake.2.Release the foot brake and drive away with‐
out delay.After the foot brake is released, the vehicle is
held in place for approx. 2 seconds.
Depending on the vehicle load or when a trailer
is being used, the vehicle may roll back slightly.
Driving off without delay
After releasing the foot brake, start driving
without delay, since the drive-off assistant will
not hold the vehicle in place for more than ap‐
prox. 2 seconds and the vehicle will begin rolling
back.◀
DSC Dynamic Stability
Control
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 at 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The laws of physics cannot be repealed, even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.◀
Indicator/warning lamps The indicator lamp flashes: DSC con‐
trols the drive forces and brake forces.
The indicator lamp lights up: DSC has
failed.Seite 123Driving stability control systemsControls123

Deactivating DSC: DSC OFF
When DSC is deactivated, driving stability is re‐
duced during acceleration and when driving in
bends.
Stabilizing interventions by the Integral Active
Steering system are only performed by the rear
axle steering.
To increase vehicle stability, activate DSC again
as soon as possible.
Deactivating DSC Press and hold the button, but not lon‐
ger than approx. 10 seconds, until the
indicator lamp for DSC OFF lights up in the in‐
strument cluster and DSC OFF is displayed.
The DSC system is switched off.
Activating DSC Press the button.
DSC OFF and the DSC OFF indicator
lamp go out.
Indicator/warning lamps
When DSC is deactivated, DSC OFF is dis‐
played in the instrument cluster.
The indicator lamp lights up: DSC is de‐
activated.
DTC Dynamic Traction
Control
The concept
The DTC system is a version of the DSC in which
forward momentum is optimized.
The system ensures maximum forward momen‐
tum on special road conditions, e.g., unplowed
snowy roads, but driving stability is limited.
It is therefore necessary to drive with appropri‐
ate caution.You may find it useful to briefly activate DTC un‐
der the following special circumstances:▷When driving in slush or on uncleared,
snow-covered roads.▷When rocking the vehicle or driving off in
deep snow or on loose surfaces.▷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.
Deactivating DTC Press the button again.
TRACTION and the DSC OFF indicator
lamp go out.
Indicator/warning lamps
When DTC is activated, TRACTION is displayed
in the tachometer.
The indicator lamp lights up: DTC Dy‐
namic Traction Control is activated.
xDrive
xDrive is the all-wheel-drive system of your ve‐
hicle. Concerted action by the xDrive and DSC
further optimize traction and driving dynamics.
The xDrive all-wheel-drive system variably dis‐
tributes the drive forces to the front and rear
axles as demanded by the driving situation and
road surface.

The warning lamp lights up. A Check
Control message is displayed.1.With the engine running, turn the steering
wheel all the way to the left and right several
times in a uniform manner until the warning
lamp disappears.2.Have the system checked if the warning
lamp does not go out after moving the steer‐
ing wheel approx. 6 times or if the steering
wheel is at an angle.
Using snow chains
Ensure that the rear axle steering is deactivated
when using snow chains, refer to page 200.
Programs
The system offers several different programs.
The programs can be selected via the Driving
Dynamics Control, refer to page 127.

Malfunction
In the event of a malfunction, the steering wheel
must be turned further, while the vehicle re‐
sponds more sensitively to steering wheel
movements in the higher speed range.
The stability-enhancing intervention may be de‐
activated.
Proceed cautiously and drive defensively.
Have the system checked.
Self-leveling suspension
The concept
The self-leveling suspension keeps the vehicle
height and ground clearance constant. The
height of the vehicle at the rear axle is main‐
tained at a predefined level under all load con‐
ditions.
The system ensures consistent comfort by
keeping spring travel constant in all driving sit‐
uations.
Malfunction
A Check Control message is displayed. A mal‐
function has occurred in the self-leveling sus‐
pension. Vehicle handling may be altered and
driving comfort may be noticeably reduced. Visit
your nearest service center.

PDC Park Distance Control
The concept
PDC supports you when parking. Objects that
you are approaching slowly in front of or behind
your vehicle are indicated by:▷Signal tones.▷Visual display.
General information
Measurements are made by ultrasound sensors
in the bumpers.
The range is approx. 6 ft/2 m.
An acoustic warning is first given:
▷By the front sensors and the two rear corner
sensors at approx. 24 in/60 cm.▷By the rear middle sensors at approx.
5 ft/1.50 m.
Notes
Check the traffic situation as well
PDC cannot serve as a substitute for the
driver's personal judgment of the traffic situa‐
tion. Check the traffic situation around the vehi‐
cle with your own eyes. Otherwise, an accident
could result from road users or objects located
outside of the PDC detection range.
Loud noises from outside and inside the vehicle
may prevent you from hearing the PDC's signal
tone.◀
Avoid driving quickly with PDC
Avoid approaching an object quickly.
Avoid driving away quickly while PDC is not yet
active.

Signal tones
When approaching an object, an intermittent
tone is sounded that indicates the position of the
object. For example, if an object is detected to
the left rear of the vehicle, a signal tone sounds
from the left rear speaker.
The shorter the distance to the object becomes,
the shorter the intervals.
If the distance to a detected object is less than
approx. 10 in/25 cm, a continuous tone is
sounded.
If objects are located both in front of and behind
the vehicle, an alternating continuous signal is
sounded.
The intermittent tone is interrupted after approx.
3 seconds:▷If the vehicle stops in front of an object that
is detected by only one of the corner sen‐
sors.▷If moving parallel to a wall.
The signal tone is switched off:
▷When the vehicle moves away from an ob‐
ject by more than approx. 4 in/10 cm.▷When transmission position P is engaged.
Volume
The volume of the PDC signal can be adjusted,
refer to user's manual for Navigation, Entertain‐
ment and Communication.
The setting is stored for the remote control cur‐
rently in use.
Visual warning
The approach of the vehicle to an object can be
shown on the Control Display. Objects that are
farther away are displayed on the Control Dis‐
play before a signal tone sounds.
A display appears as soon as Park Distance
Control (PDC) is activated.

Low objects already displayed, e.g., curbs, can
move into the blind area of the sensors before or
after a continuous tone sounds.
High, protruding objects such as ledges may not
be detected.
False warnings
PDC may issue a warning under the following
conditions even though there is no obstacle
within the detection range:
▷In heavy rain.▷When sensors are very dirty or covered in
ice.▷When sensors are covered in snow.▷On rough road surfaces.▷In large buildings with right angles and
smooth walls, e.g., in underground garages.▷In heavy exhaust.▷Due to other ultrasound sources, e.g.,
sweeping machines, high pressure steam
cleaners or neon lights.Malfunction
