Driving stability control systems
Driving off without delay
Antilock Brake System ABS
ABS prevents locking of the wheels during brak‐
ing.
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.◀
The vehicle remains steerable even during full
brake applications, thus increasing active
safety.
ABS is operational every time you start the en‐
gine.
DSC Dynamic Stability
Control
Brake assistant
The concept
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.
This system utilizes all of the benefits provided
by ABS.
DSC prevents traction loss in the driving wheels
when driving away and accelerating.
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 at individual wheels.
Do not reduce the pressure on the brake pedal
for the duration of the full braking.
Adjust your driving style to the situation
An appropriate driving style is always the
responsibility of the driver.
Adaptive brake assistant
The laws of physics cannot be repealed, even
with DSC.
In combination with the Active Cruise Control,
this system ensures that the brakes respond
even more rapidly when braking in critical situa‐
tions. Refer also to Collision warning, refer to
page 110.
Therefore, do not reduce the additional safety
margin by driving in a risky manner.◀
Deactivating DSC: DSC OFF
DSC can be deactivated. To do this, activate the
DSC OFF program.
Drive-off assistant
This is performed via the Dynamic Driving Con‐
trol, refer to page 102.
This system supports driving away on gradients.
The parking brake is not required.
1. Hold the vehicle in place with the foot brake.
Indicator/warning lamps
2. Release the foot brake and drive away with‐
out delay.
The indicator lamp flashes: DSC con‐
trols the drive forces and brake forces.
After the foot brake is released, the vehicle is
held in place for approx. 2 seconds.
The indicator lamp lights up: DSC has
failed.
Depending on the vehicle load, the vehicle may
roll back slightly.

You can activate the Hill Descent Control at
speeds below approx. 22 mph/35 km/h. When
driving downhill, the vehicle reduces its speed
to approx. twice walking speed and then keeps
its speed constant.
DTC Dynamic Traction
Control
The concept
The DTC system is a version of the DSC in which
forward momentum is optimized.
While you are actively braking, the system is on
standby. The system does not brake the vehicle
during this time.
The system ensures maximum forward momen‐
tum on special road conditions, e.g., unplowed
snowy roads, but driving stability is limited.
Increasing or decreasing vehicle speed
It is therefore necessary to drive with appropri‐
ate caution.
You can specify your desired speed in the range
from approx. 4 mph/6 km/h to approx. 15 mph/
25 km/h using the rocker switch of the cruise
control on the steering wheel. You can change
the vehicle speed by pressing on the accelerator
lightly.
You may find it useful to briefly activate DTC un‐
der the following special circumstances:
▷
▷
▷
When driving in slush or on uncleared,
snow-covered roads.
When rocking the vehicle or driving off in
deep snow or on loose surfaces.
When driving with snow chains.
Deactivating/activating DTC Dynamic
Traction Control
The system can be deactivated/activated via the
TRACTION and SPORT+ programs of the Dy‐
namic Driving Control, refer to page 102.
▷
▷
Press up the rocker switch to the point of
resistance: the speed increases gradually.
Press up the rocker switch past the point of
resistance: the speed increases while the
rocker switch is pressed.
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.
▷
▷
Press down the rocker switch to the point of
resistance: the speed decreases gradually.
Press down the rocker switch past the point
of resistance: when driving forward, the
speed decreases to approx. 6 mph/10 km/h;
when reversing, the speed decreases to ap‐
prox. 4 mph/6 km/h.
HDC Hill Descent Control*
The concept
HDC is a downhill driving assistant that auto‐
matically controls vehicle speed on steep down‐
hill gradients. Without requiring brake applica‐
tion, the vehicle moves at slightly more than
twice walking speed.

Dynamic Drive*
The concept
Dynamic Drive reduces the lateral inclination of
the vehicle that occurs during rapid driving in
curves or during quick evasive maneuvers.
Driving stability and driving comfort are in‐
creasedunderalldrivingconditions. Thesystem
utilizes active stabilizer bars on the front and rear
axles that react immediately to all driving situa‐
tions.
Press the button; the LED above the but‐
ton lights up.

The concept
Malfunction
This system reduces undesirable vehicle mo‐
tion when using a dynamic driving style or trav‐
eling on uneven road surfaces.
A message is displayed in the instrument clus‐
ter. HDC is not available, e.g., due to elevated
brake temperatures.
The system enhances driving dynamics and
comfort as required for the road surface and

Integral Active Steering*
Theprogramscanbeselected via DynamicDriv‐
ing Control, refer to page 102.
The concept
SPORT
Integral Active Steering is a combination of Ac‐
tive Steering and rear axle steering.
Consistently sporty tuning of the Integral Active
Steering for greater driving agility.
Active Steering varies the steering angle of the
wheels in relation to the steering wheel move‐
ment as a function of the speed.
NORMAL
Balanced tuning of the Integral Active Steering
for optimal traveling comfort.
At speeds up to approx. 37 mph/60 km/h, e.g.,
in curves, the steering angle is increased, i.e.,
steering becomes more direct.
Malfunction
The rear axle steering acts to increase maneu‐
verability by turning the rear wheels slightly in a
direction opposite to the front wheels.
In the event of a malfunction, the steering wheel
must be turned further, while the vehicle re‐
sponds more sensitively to steering wheel
movements in the higher speed range.
At higher speeds, the steering angle is increas‐
ingly reduced.
The stability-enhancing intervention may be de‐
activated.
The rear wheels are turned to the same angle as
the front wheels.
Proceed cautiously and drive defensively.
Have the system checked.
In critical situations, Integral Active Steering can
specifically steer the front and rear wheels to
stabilize the vehicle before the driver intervenes,
e.g., when braking where road conditions differ
on the left and right sides of the vehicle.
Self-leveling suspension*
Initializing
The concept
In rare cases, it may become necessary to initi‐
alize the Integral Active Steering.
The self-leveling suspension keeps the vehicle
height and ground clearance constant. The
height of the vehicle at the rear axle is main‐
tained at a predefined level under all load con‐
ditions.
The warning lamp lights up. A Check
Control message is displayed.
The system ensures consistent comfort by
keeping spring travel constant in all driving sit‐
uations.
1. With the engine running, turn the steering
wheel all the way to the left and right several
times in a uniform manner until the warning
lamp disappears.
2. Have the system checked if the warning
lamp does not go out after moving the steer‐
