Driving stability control systems  
This system utilizes all of the benefits provided  
by ABS.  
Vehicle equipment  
This chapter describes all series equipment as  
well as country-specific and special equipment  
offered for this model series.Therefore, it also  
describes equipment that may not be found in  
your vehicle, for instance due to the selected  
special equipment or the country version. This  
also applies to safety-related functions and sys‐  
tems.  
Do not reduce the pressure on the brake pedal  
for the duration of the full braking.  
Dynamic Stability Control  
DSC  
The concept  
DSC prevents traction loss in the driving wheels  
when driving away and accelerating.  
Antilock Brake System ABS  
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 to the individual wheels.  
ABS prevents locking of the wheels during brak‐  
ing.  
The vehicle remains steerable even during full  
brake applications, thus increasing active  
safety.  
Adjust your driving style to the situation  
ABS is operational every time you start the en‐  
gine.  
An appropriate driving style is always the  
responsibility of the driver.  
The laws of physics cannot be repealed, even  
with DSC.  
CBC Cornering Brake Control  
Do not reduce the additional safety margin with  
a risky driving style, as otherwise there is a risk  
of an accident.◀  
When braking during curves or when braking  
during a lane change, driving stability and steer‐  
ing response are improved further.  
Deactivating DSC: DSC OFF  
Electronic brake-force  
distribution  
The system controls the brake pressure in the  
rear wheels to ensure stable braking behavior.  
When DSC is deactivated, driving stability is re‐  
duced during acceleration and when driving in  
bends.  
To increase vehicle stability, activate DSC again  
as soon as possible.  
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.

trol and DSC are deactivated together.  
Dynamic Traction Control  
DTC  
The concept  
The DTC system is a version of the DSC in which  
forward momentum is optimized.  
A message appears on the Control Display.  
Please note any supplementary information that  
appears there.  
The system ensures maximum forward momen‐  
tum on special road conditions, e.g., unplowed  
snowy roads, but driving stability is limited.  
Activating DSC  
Press the button.  
It is therefore necessary to drive with appropri‐  
ate caution.  
DSC OFF and the indicator lamp in the instru‐  
ment cluster go out.  
You may find it useful to briefly activate DTC un‐  
der the following special circumstances:  
For better control  
▷
When driving in sand, on snowy inclines, in  
slush, or on unplowed, snow-covered road  
surfaces  
The indicator lamp flashes: DSC con‐  
trols the drive forces and brake forces.  
The indicator lamp lights up: DSC and  
DTC has failed.

xDrive  
xDrive is the all-wheel-drive system of your ve‐  
hicle. The combined effects of xDrive and DSC  
further optimize the traction and dynamic driv‐  
ing characteristics. The 4-wheel drive system  
xDrive variably distributes the drive forces to the  
front and rear axle depending on the driving sit‐  
uation and prevailing road conditions.  
Press the button.  
Dynamic Performance  
Control  
TRACTION is displayed in the instrument clus‐  
ter and the indicator lamp for DSC OFF lights up.  
The concept  
Dynamic Performance Control optimizes the  
handling characteristics of your vehicle when  
starting off, cornering, and during evasive ma‐  
neuvers.  
Deactivating DTC  
Press the button again.  
TRACTION and the indicator lamp in the instru‐  
ment cluster go out.  
To achieve this, the system variably distributes  
the drive torque of the rear axle to the two rear  
wheels. This further increases the steering pre‐  
cision and tracking stability of your vehicle.  
For better control  
The indicator lamp flashes: DTC con‐  
trols the drive forces and brake forces.

Increasing speed  
The concept  
Pull to the resistance point: reduce the  
speed to approx. 4 mph/6 km/h  
HDC is a downhill driving assistant that auto‐  
matically controls vehicle speed on steep down‐  
hill gradients. The vehicle moves at approxi‐  
mately walking speed without braking  
intervention by the driver.  
3
Pull beyond the resistance point: on inclines  
over 10 %, reduce the speed to ap‐  
prox. 3 mph/4 km/h  
You can activate the Hill Descent Control at  
speeds below approx. 22 mph/35 km/h. When  
moving downhill at speeds below approx.  
22 mph/35 km/h, the vehicle reduces its speed  
to approximately walking speed, approx.  
5 mph/8 km/h and keeps it constant.  
Activating HDC  
Only use HDC in transmission positions D or R.  
Increasing or reducing speed  
The speed can be changed in the range from  
approx. 4 mph/6 km/h to ap‐  
prox. 15 mph/25 km/h by pressing the acceler‐  
ator or brake pedal lightly.  
Press the button; the LED above the button  
lights up.  
A target speed within the same range can be  
specified using the lever of the cruise control.  
The LED flashes when the brakes are applied  
automatically.  
On inclines over 10 %, you can reduce the speed  
to approx. 3 mph/4 km/h. Pull the lever of the  
cruise control beyond the resistance point, ar‐  
row 3.  
Deactivating HDC  
Press the button again; the LED goes out. HDC  
is automatically deactivated above approx.  
37 mph/60 km/h.

Adaptive Drive  
The concept  
Drive-off assistant  
This system supports driving away on gradients.  
The parking brake is not required.  
Adaptive Drive reduces the body roll which oc‐  
curs when cornering quickly or during fast eva‐  
sive maneuvers. In addition, Adaptive Drive re‐  
duces the steering angle requirement, improves  
the running comfort, and enhances the dynamic  
driving characteristics of your vehicle.  
1. Hold the vehicle in place with the foot brake.  
2. Release the foot brake and drive away with‐  
out delay.

more. This improves the handling of your vehicle  
over the entire speed range.  
In critical situations, the system can make tar‐  
geted corrections to the steering angle provided  
bythedriver and thusstabilize thevehicle before  
the driver intervenes.  
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.◀  
Malfunction  
The warning lamp lights up yellow and  
a message is shown on the Control  
Display. The active steering is defec‐  
tive or has been temporarily deacti‐  
Self-leveling suspension  
vated. At low speeds, greater steering wheel  
movements are required, whereas at higher  
speeds, the vehicle reacts more sensitively to  
steering wheel movements. The stability-pro‐  
moting intervention can also be deactivated.  
Proceed cautiously and drive defensively.  
The concept  
The self-leveling suspension on the rear axle  
assures a continuous ground clearance.  
To do so, the height of the vehicle is measured  
by sensors at both rear wheels.  
If the actual height deviates from the defined  
height, such as due to cargo in the vehicle, this  
difference is compensated very quickly. In ad‐  
dition, spring motions resulting from cornering  
or irregularities in the road surface are reduced  
to a minimum.  
Deactivation  
Active steering deactivates in order to carry out  
an initialization. This deactivation is displayed by  
means of a message. The initialization can take  
several minutes.  
The system works automatically.  
If the message does not disappear during the  
current trip, have the system checked.  
Malfunctions  
Malfunctions are displayed via Check Control,  
refer to page 83.  
Defect  
In the event of a defect, a corresponding text  
message is displayed. Have the system  
checked.  
Active steering  
The concept  
The active steering actively varies the steering  
angle of the front wheels in relation to the steer‐  
ing wheel movements. In addition, it also varies  
the steering force required for steering depend‐  
ing on the vehicle's speed.  
When you are driving in the low speed range, for  
instance in a town or when parking, the steering  
angle increases, i.e., steering becomes very di‐  
rect. In the higher speed range, on the other  
hand, the steering angle is reduced more and
