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The laws of physics cannot be repealed, even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.

Deactivating DSC
DSC and DTC deactivated.
Press and hold the button, but not longer than
approx. 10 seconds, until the indicator lamp for
DSC lights up in the instrument cluster and DSC
OFF is displayed. DTC Dynamic Traction Con‐
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.
▷
▷
When rocking a vehicle free or starting off in
deep snow, sand, or on loose ground
DSC deactivated:
When driving with snow chains.
The indicator lamp lights up and
DSC OFF appears in the instrument
cluster.
Deactivating/activating DTC Dynamic
Traction Control
Activating the Dynamic Traction Control DTC
provides maximum traction on loose ground.
Driving stability is limited during acceleration
and when driving in bends.

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.
Display
The indicator lamp lights up: DSC and
DTC has failed.
The Control Display shows how xDrive and Dy‐
namic Performance Control are distributing the
drive forces.
DTC activated:
The indicator lamp lights up and TRAC‐
TION appears in the instrument cluster.

2. "Torque distribution"
DTC is activated.
The current distribution of drive forces is indi‐
cated by arrows pointing to all four wheels.
The highlighted arrows show the drive forces
currently present. The longer an arrow is, the
greater the drive forces in the associated wheel.

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.

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‐

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
