Vehicle features and options
DSC Dynamic Stability
Control
This chapter describes all standard, country-
specific 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 using these functions and
systems, the applicable country provisions
must be observed.
Concept
Within the physical limits, the system helps to
keep the vehicle on a steady course by reduc‐
ing engine speed and by applying brakes to
the individual wheels.
General information
Dynamic Stability Control detects, e.g., the fol‐
lowing unstable driving conditions:
Anti-lock Braking System
ABS
ABS prevents locking of the wheels during
braking.
▷
▷
Fishtailing, which can lead to oversteering.
Loss of traction of the front wheels, which
can lead to understeering.
Dynamic Traction Control DTC, refer to
page 128, is a version of the DSC where for‐
ward momentum is optimized.
The vehicle maintains its steering power even
during full brake applications, thus increasing
active safety.
Safety information
ABS is operational every time you start the en‐
gine.
WARNING
The system does not release from the
personal responsibility to correctly assess 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
the driving style to the traffic conditions. Watch
traffic closely and actively intervene in the re‐
spective situations.◀
Brake assistant
When you apply the brakes rapidly, this system
automatically produces the greatest possible
braking force boost. It reduces the braking dis‐
tance to a minimum during emergency stop.
This system utilizes all of the benefits provided
by ABS.
WARNING
Do not reduce the pressure on the brake pedal
for the duration of the emergency stop.
When driving with roof load, e.g., with
roof-mounted luggage rack, driving safety may
not be ensured in driving-critical situations due
to the elevated center of gravity. There is a risk
of accidents or risk of property damage. Do not
deactivate Dynamic Stability Control DSC
when driving with roof load.◀

Concept
Indicator/warning lights
DTC is a version of the DSC where forward
momentum is optimized.
The indicator lamp flashes: DSC con‐
trols the drive and braking forces.
The system ensures maximum headway on
special road conditions or loose road surfaces,
e.g., unplowed snowy roads, but with some‐
what limited driving stability.
The indicator lamp lights up: DSC has
malfunctioned.
When DTC is activated, the vehicle has maxi‐
mum traction. Driving stability is limited during
acceleration and when driving in curves.
Deactivating DSC: DSC OFF
General information
Therefore, drive with appropriate caution.
When DSC is deactivated, driving stability is
reduced during acceleration and when driving
in curves.
You may find it useful to briefly activate DTC
under the following special circumstances:
To increase vehicle stability, activate DSC
again as soon as possible.

HDC Hill Descent Control
Press button again.
TRACTION and the DSC OFF indica‐
tor lamp go out.
Concept
HDC is a downhill driving assistant that auto‐
matically controls vehicle speed on steep
downhill gradients. Without applying the
brakes, the vehicle moves at slightly more than
walking speed. It the brakes are actively ap‐
plied, the system distributes force according to
the traction.
Performance Control
Performance Control enhances the agility of
the vehicle.
Vehicle stability and maneuverability are im‐
proved on downhill gradients.
To increase maneuverability, with a corre‐
spondingly sporty driving style, wheels are
braked individually. The resulting braking
power is simultaneously largely compensated
by an engine intervention.
Hill Descent Control can be activated at
speeds below approx. 22 mph/35 km/h. When
driving downhill, the vehicle reduces its speed
and then keeps its speed constant.
Only use HDC in low gears or in selector lever
position D or R.
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.
Increasing or decreasing vehicle
speed
Specify desired speed in the range from ap‐
prox. 4 mph/6 km/h to approx. 15 mph/25 km/h
using the rocker switch of the cruise control on
the steering wheel. Vehicle speed can be
changed by lightly accelerating.

Dynamic Damping Control
Concept
This system reduces undesirable vehicle mo‐
tion when using a dynamic driving style or trav‐
eling on uneven road surfaces.
Activating HDC
This enhances the driving dynamics and driv‐
ing comfort depending on the road surface
condition and driving style.
Programs
The system offers several different programs.
The programs can be selected via Driving Dy‐
namics Control.
SPORT
Press button; the LED above the button
lights up.
Consistently sporty control of the shock ab‐
sorbers for greater driving agility.
SPORT+
Deactivating HDC
Consistently sporty control of the shock ab‐
sorbers for greater driving agility when driving
with limited driving stabilization.
Press button again. The LED goes out.
HDC is automatically deactivated above
approx. 37 mph/60 km/h.
COMFORT/ECO PRO
Balanced control of the vehicle.
Display in the instrument cluster
The selected speed is displayed
in the speedometer.
Variable sport steering
▷
Green: the system is actively
braking the vehicle.
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.
▷
Orange: the system is on
standby.
It also varies the force required to turn the
wheels in accordance with the vehicle speed.
Malfunction
A message is displayed in the instrument clus‐
ter. HDC is not available, e.g., due to elevated
brake temperatures.
This results in a sporty steering response. In
addition, it becomes easier to steer during
parking and maneuvering.

Concept
The Servotronic varies the steering force re‐
quired to turn the wheels in accordance with
the vehicle speed. At low speeds, the steering
force is strongly supported, i. e. during steer‐
ing, low force is required. As the speed in‐
creases, the assistance of the steering force is
reduced.
