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.  
When driving in slush or on uncleared,  
snow-covered roads.  
When freeing vehicle from deep snow or  
driving off from loose ground.

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.

Press the rocker switch down past the  
point of resistance: when driving forward,  
the speed decreases to approx.  
6 mph/10 km/h; when reversing, the speed  
decreases to approx. 4 mph/6 km/h.  
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.

veyed.  
Automatic program change  
The system may automatically switch to COM‐  
FORT in the following situations:  
Failure of Dynamic Damping Control.  
Failure of DSC Dynamic Stability Control.  
The vehicle has a flat tire.  
Driving Dynamics Control  
Concept  
When activating cruise control in TRAC‐  
TION or DSC OFF mode.  
The Driving Dynamics Control helps to fine-  
tune the vehicle's settings and features. Vari‐  
ous programs can be selected for this purpose.  
The Driving Dynamics Control and the DSC  
OFF buttons can each be used to activate a  
program.  
DSC OFF  
When DSC OFF, refer to page 128, is active,  
driving stability is limited during acceleration  
and when driving in curves.  
Overview  
TRACTION
