ject to physical limits, DSC helps to keep the
vehicle on a steady course by reducing engine
speed and by applying brakes at individual
wheels.
Vehicle equipment
All standard, country-specific and optional
equipment that is offered in the model series is
described in this chapter. Therefore, equip‐
ment is also described that is not available in a
vehicle, e. g., because of the selected optional
equipment or country variant. This also applies
for safety-related functions and systems.
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The laws of physics cannot be repealed, even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.◀
Antilock Brake System ABS
ABS prevents locking of the wheels during
braking.
Indicator/warning lamps
The vehicle remains steerable even during full
brake applications, thus increasing active
safety.
The indicator lamp flashes: DSC con‐
trols the drive forces and brake forces.
The indicator lamp lights up: DSC has
failed.
ABS is operational every time you start the en‐
gine.
Deactivating DSC: DSC OFF
When DSC is deactivated, driving stability is
reduced during acceleration and when driving
in bends.
Brake assistant
When you apply the brakes rapidly, this system
automatically produces the maximum braking
force boost. This then reduces braking dis‐
tance to a minimum during full braking. This
system utilizes all of the benefits provided by
ABS.
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.
Do not reduce the pressure on the brake pedal
for the duration of the full braking.
The DSC system is switched off.
DSC Dynamic Stability

The concept
DSC prevents traction loss in the driving
wheels when driving away and accelerating.

played in the instrument cluster.

xDrive
DTC Dynamic Traction
Control
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 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.
Dynamic Damping Control
It is therefore necessary to drive with appropri‐
ate caution.
The concept
This system reduces undesirable vehicle mo‐
tion when using a dynamic driving style or trav‐
eling on uneven road surfaces.
You may find it useful to briefly activate DTC
under the following special circumstances:
▷
▷
▷
When driving in slush or on uncleared,
snow-covered roads.
The system enhances driving dynamics and
comfort as required for the road surface and
driving style.
When rocking the vehicle or driving off in
deep snow or on loose surfaces.
When driving with snow chains.
Programs
The system offers several different programs.

Variable sport steering
driving stability is limited during acceleration
and when driving in bends.
The variable sport steering increases the
steering angle of the front wheels at large
steering wheel angles, e.g., in tight curves or
when parking. Steering becomes more direct.
TRACTION
It also varies the force required to turn the
wheels in accordance with the vehicle speed.
When TRACTION is active, the vehicle has
maximum traction on loose road surfaces. DTC

celeration and when driving in bends.
This results in a sporty steering response. In
addition, it becomes easier to steer during
parking and maneuvering.
SPORT+
Driving Dynamics Control
Sporty driving with optimized chassis and
adapted engine control with limited driving sta‐
bilization.
The concept
The Driving Dynamics Control can be used to
adjust the certain characteristics of the vehicle.
Various programs can be selected for this pur‐
pose. The Driving Dynamics Control and the
DSC OFF buttons can each be used to activate
a program.
Dynamic Traction Control is switched on.
