Vehicle features and
options
DSC Dynamic Stability
Control
This chapter describes all standard, country-spe‐
cific and optional features offered with the series.
It also describes features that are not necessarily
available in your vehicle, e. g., due to the selected
options or country versions. This also applies to
safety-related functions and systems. When us‐
ing these functions and systems, the applicable
laws and regulations must be observed.
Concept
Within the physical limits, the system helps to
keep the vehicle on a steady course by reducing
engine speed and by applying brakes to the indi‐
vidual wheels.
General information
DSC detects the following unstable driving con‐
ditions, for instance:
Anti-lock Braking System
ABS
▷ Fishtailing, which can lead to oversteering.
▷ Loss of traction of the front wheels, which
can lead to understeering.
ABS prevents locking of the wheels during brak‐
ing.
Dynamic Traction Control DTC, refer to
page 171, is a version of the DSC where forward
momentum is optimized.
The vehicle maintains its steering power even
during full brake applications, thus increasing ac‐
tive safety.
Safety information
ABS is operational every time you start the en‐
gine.
WARNING
The system cannot serve as a substitute for the
driver’s personal judgment in assessing the
traffic situation. Based on the limits of the sys‐
tem, it cannot independently react to all traffic
situations. There is a risk of an accident. Adjust
driving style to traffic conditions. Watch traffic
closely and actively intervene where appropri‐
ate.
Brake assistant
When you apply the brakes rapidly, this system
automatically boosts the vehicle braking capabil‐
ity to the furthest possible extent. It reduces the
braking distance to a minimum during emer‐
gency stop. This system utilizes all of the capa‐
bilities provided by the Antilock Brake System
ABS.
WARNING
Do not reduce the pressure on the brake pedal
for the duration of the emergency stop.
When driving with a roof load, for instance with
roof-mounted luggage rack, the vehicle's cen‐
ter of gravity is higher, which increases the risk
of the vehicle tipping in critical driving situa‐
tions. There is a risk of accidents or risk of
170

damage to property. Do not deactivate DSC
Dynamic Stability Control when driving with
roof load.
The steering and, depending on the equipment,
suspension are tuned for sporty driving.

Indicator/warning lights
Concept
DTC is a version of the DSC Dynamic Stability
Control where forward momentum is optimized.
The indicator light flashes: DSC controls
the drive and braking forces.
The indicator light lights up: DSC has
malfunctioned.
The system ensures maximum headway on spe‐
cial road conditions or loose road surfaces, for in‐
stance unplowed snowy roads, but with some‐
what limited driving stability.
Deactivating DSC: DSC OFF
General information
When DSC is deactivated, driving stability is re‐
duced during acceleration and when driving in
curves.
When DTC is activated, the vehicle has maxi‐
mum traction. Driving stability is limited during
acceleration and when driving in curves.
Drive carefully.
You may find it useful to briefly activate DTC un‐
der the following special circumstances:
To increase vehicle stability, activate DSC again
as soon as possible.
▷ When driving in slush or on uncleared, snow-
covered roads.
Deactivating DSC
▷ When driving off from deep snow or loose
ground.
Press and hold this button but not lon‐
ger than approx. 10 seconds, until the
indicator light for DSC OFF lights up in the in‐
strument cluster and displays DSC OFF.
▷ When driving with snow chains.
DSC is switched off.

Variable sport steering
The support offered by the variable sport steer‐
ing changes according to the angle by which the
steering wheel has been turned and the speed.
xDrive
So, for instance the steering angle of the front
wheels is made larger when parking or taking
tight corners. This makes it easier to drive
around bends.
xDrive is the all-wheel-drive system of your vehi‐
cle. Concerted action by the xDrive and DSC Dy‐
namic Stability Control further optimizes traction
and driving dynamics. The xDrive all-wheel-drive
system variably distributes the drive forces to the
front and rear axles as demanded by the driving
situation and road surface.
Furthermore, the system provides the steering
with more support at low speeds than at higher
ones. This makes it easier to park, for instance,
and makes steering more direct when driving at
faster speeds.
Adaptive chassis
By taking the angle by which the steering wheel
has been turned and the speed into account, a
sporty steering response adapted to the particu‐
lar driving situation can be achieved.
Concept
This system reduces undesirable vehicle motion
when using a dynamic driving style or traveling
on uneven road surfaces.
Driving Dynamics Control
This enhances the driving dynamics and driving
comfort depending on the road surface condition
and driving style.
Concept
The Driving Dynamics Control helps to fine-tune
the vehicle's settings and features. Various pro‐
grams can be selected for this purpose. The
Driving Dynamics Control and the DSC OFF but‐
tons can each be used to activate a program.
Programs
The system offers several different programs.
The programs can be selected via Driving Dy‐
namics Control.

Drive-off assistant
Concept
This system supports driving off on uphill grades.
The parking brake is not required.
Driving off with the drive-off
assistant
1. Hold the vehicle in place with the foot brake.
2. Release the foot brake and drive off without
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
used, the vehicle may roll back slightly.
Servotronic
Concept
Servotronic is a speed-dependent power steer‐
ing function.
The system provides the steering force with
more support at low speeds than at higher ones.
This makes it easier to park, for instance, and
makes steering more direct when driving at
faster speeds.
Furthermore, the steering force adapts according
to the driving program, so that a direct, sporty
feel or a comfortable steering response is con‐
veyed.
