To increase the maneuverability, the rear
wheel on the outside of the curve is acceler‐
ated when the driving style is correspondingly
sporty.
The steering responds directly; simultane‐
ously, the understeering tendency of the four-
wheel drive is reduced.
With the oversteering tendency, the system
exerts a stabilizing effect by accelerating the
rear wheel on the inside of the curve.
The system noticeably improves the traction
and simultaneously increases the driving
safety, especially on road surfaces having fluc‐
tuating coefficients of friction.
DSC Dynamic Stability
Control
The concept
DSC prevents traction loss in the power
wheels when driving off and accelerating.
DSC also recognizes unstable vehicle condi‐
tions such as fishtailing or nose-diving. Within the physical limits DSC helps to keep the vehi‐
cle on a steady course by reducing engine
speed and by applying brakes to the individual
wheels.
Note 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The laws of physics cannot be repealed, not
even with DSC.
Therefore, do not reduce the additional safety
margin by driving in a risky manner.◀
Do not deactivate DSC when driving with
roof load
Do not deactivate Dynamic Stability Control
DSC when driving with roof load, e.g. roof-
mounted luggage rack.Otherwise, driving safety is not given in driv‐
ing-critical situation due to the elevated center
of gravity.◀

DSC OFF button
Indicator/warning lights The indicator lamp flashes: DSC con‐
trols the drive and braking forces.
The indicator lamp lights up: DSC has
failed.
Deactivating DSC: DSC OFF
When DSC is deactivated, driving stability is
reduced during acceleration and when driving
in curves.
To increase vehicle stability, activate DSC
again as soon as possible.
Deactivating DSC Press and hold this button but not lon‐
ger than approx. 10 seconds, until the
indicator lamp for DSC OFF lights up in the in‐
strument cluster and displays DSC OFF.
The DSC system is switched off.
The steering and, depending on the equip‐
ment, suspension are tuned for sporty driving.

Display in the instrument clusterThe selected speed is displayed
in the speedometer.▷Green: the system is actively
braking the vehicle.▷Orange: the system is on
standby.
Malfunction
A message is displayed in the instrument clus‐
ter. HDC is not available, e.g., due to elevated
brake temperatures.
Active 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 lower speeds, for example during turning or
maneuvering, the steering angle is increased,
that is to say the steering becomes more di‐
rect.
At higher speeds, the steering angle is increas‐
ingly reduced.
This enables even more precise handling at
high speeds and more responsive steering
with reduced steering angle at low speeds.
Active roll stabilization The concept
The system 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 sys‐
tem utilizes active stabilizer bars on the front
and rear axles that react immediately to all driv‐
ing situations.
Programs
The system offers two different programs.
Select the programs via the Driving Dynamics
Control, refer to page 137.
SPORT Sporty tuning for greater driving agility.
COMFORT
Comfort-oriented tuning for optimal comfort.
Vertical Dynamic 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 fitting road surface and driving style.
Programs The system offers several different programs.
Select the programs via the Driving Dynamics
Control, refer to page 137.
SPORT/SPORT+
Consistently sporty control of the shock ab‐
sorbers for greater driving agility.
COMFORT/ECO PRO Balanced tuning.
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.Seite 136ControlsDriving stability control systems136

Minimum tread depth
Wear indicators are distributed around the
tire's circumference and have the legally re‐
quired minimum height of 0.063 in/1.6 mm.
They are marked on the side of the tire with
TWI, Tread Wear Indicator.
Tire damage
General information
Inspect your tires often for damage, foreign
objects lodged in the tread, and tread wear.
Hints
Driving over rough or damaged road surfaces,
as well as debris, curbs and other obstacles
can cause serious damage to wheels, tires and
suspension parts. This is more likely to occur
with low-profile tires, which provide less cush‐
ioning between the wheel and the road. Be
careful to avoid road hazards and reduce your
speed, especially if your vehicle is equipped
with low-profile tires.
Indications of tire damage or other vehicle de‐
fects:
▷Unusual vibrations while driving.▷Unusual handling such as a strong ten‐
dency to pull to the left or right.
Damage can, e. g., be caused by driving over
curbs, road damage, or similar things.
In case of tire damage
If there are indications of tire damage, re‐
duce your speed immediately and have the
rims and tires checked right away; otherwise,
there is the increased risk of an accident.
Drive carefully to the nearest service center.
Have the vehicle towed or transported there.
Otherwise, tire damage can become life threat‐
ening for vehicle occupants and also other traf‐
fic.◀
Repair of tire damage
For safety reasons, the manufacturer of
your vehicle recommends that you do not have
damaged tires repaired; they should be re‐
placed. Otherwise, damage can occur as a re‐
sult.◀
Changing wheels and tires
Mounting Information on mounting tires
Have mounting and balancing performed
only by a service center.
If work is not carried out properly, there is a
danger of subsequent damage and related
safety hazards.◀
Wheel and tire combination
You can ask the service center about the right
wheel/tire combination and wheel rim versions
for the vehicle.
Incorrect wheel and tire combinations impair
the function of a variety of systems such as
ABS or DSC.
To maintain good handling and vehicle re‐
sponse, use only tires with a single tread con‐
figuration from a single manufacturer.
Following tire damage, have the original wheel
and tire combination remounted on the vehicle
as soon as possible.Seite 209Wheels and tiresMobility209
