Driving stability control systems
Antilock Brake System ABS
ABS
prevents locking of the wheels during brak‐
ing.
The vehicle remains steerable even during full
brake applications, thus increasing active
safety.
ABS is operational every time you start the en‐
gine.
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.
This system utilizes all of the benefits provided
by ABS.
Do not reduce the pressure on the brake pedal
for the duration of the full braking.
Adaptive brake assistant
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.
Drive-off assistant
This system supports driving away on gradients.
The parking brake is not required.
1. Hold the vehicle in place with the foot brake.
2. Release the foot brake and drive away with‐
out delay.
After the foot brake is released, the vehicle is
held in place for approx. 2 seconds.
Depending on the vehicle load, the vehicle may
roll back slightly. 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.◀
DSC Dynamic Stability
Control
The concept
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.
Adjust your driving style to the situation
An appropriate driving style is always the
responsibility of the driver.
The laws of physics cannot be repealed, even
with DSC.
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.
This is performed via the Dynamic Driving Con‐
trol, refer to page 102.
Indicator/warning lamps The indicator lamp flashes: DSC con‐
trols the drive forces and brake forces.
The indicator lamp lights up: DSC has
failed. Seite 98

Adaptive Drive*
The concept
Adaptive
Drive* includes the following systems:
▷ Dynamic Drive, refer to page 100
▷ Dynamic Damping Control, refer to
page 100
The system increases driving stability and driv‐
ing comfort. 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‐
creased

under all driving conditions. The system
utilizes active stabilizer bars on the front and rear
axles that react immediately to all driving situa‐
tions.
Programs
The system offers two different programs.
The programs can be selected via Dynamic Driv‐
ing Control, refer to page 102.
SPORT
Sporty tuning for greater driving agility.
NORMAL
Comfort-oriented tuning for optimal comfort.
Dynamic Damping Control*
The concept
This system reduces undesirable vehicle mo‐
tion when using a dynamic driving style or trav‐
eling on uneven road surfaces.
The system enhances driving dynamics and
comfort as required for the road surface and
driving style.
Programs
The system offers three different programs.
The programs can be selected via Dynamic Driv‐
ing Control, refer to page 102.

NORMAL
Balanced tuning between the COMFORT and
SPORT programs.
COMFORT
Comfort-oriented
tuning of the shock absorbers
for optimal traveling comfort.
Integral Active Steering*
The concept
Integral Active Steering is a combination of Ac‐
tive Steering and rear axle steering.
Active Steering varies the steering angle of the
wheels in relation to the steering wheel move‐
ment as a function of the speed.
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.
The rear axle steering acts to increase maneu‐
verability by turning the rear wheels slightly in a
direction opposite to the front wheels.
At higher speeds, the steering angle is increas‐
ingly reduced.
The rear wheels are turned to the same angle as
the front wheels.
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.
Initializing
In rare cases, it may become necessary to initi‐
alize the Integral Active Steering.
The warning lamp lights up. A Check
Control message is displayed.
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‐ ing wheel approx. 6 times or if the steering
wheel is at an angle.
Using snow chains
Ensure
that the rear axle steering is deactivated
when using snow chains, refer to page 252.
Programs
The system offers two different programs.
The programs can be selected via Dynamic Driv‐
ing Control, refer to page 102.
SPORT
Consistently sporty tuning of the Integral Active
Steering for greater driving agility.
NORMAL
Balanced tuning of the Integral Active Steering
for optimal traveling comfort.
Malfunction
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.
The stability-enhancing intervention may be de‐
activated.
Proceed cautiously and drive defensively.
Have the system checked.
Self-leveling suspension*
The concept
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 system ensures consistent comfort by
keeping spring travel constant in all driving sit‐
uations.
