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The laws of physics cannot be repealed, not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.◀

in curves.
To increase vehicle stability, activate DSC
again as soon as possible.

ger than approx. 10 seconds, until the
indicator lamp for DSC OFF lights up in the in‐

DTC Dynamic Traction
Control
The concept The DTC system is a version of the DSC where
forward momentum is optimized.
The system ensures maximum headway on
special road conditions or loose road surfaces,
e.g., unplowed snowy roads, but with some‐
what limited driving stability.
Activating the Dynamic Traction Control DTC
provides maximum traction. Driving stability is
limited during acceleration and when driving in
curves.
Therefore drive with appropriate caution.
You may find it useful to briefly activate DTC
under the following special circumstances:▷When driving in slush or on uncleared,
snow-covered roads.▷When freeing vehicle from deep snow or
driving off from loose grounds.▷When driving with snow chains.

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.

HDC Hill Descent Control
The concept HDC is a downhill driving assistant that auto‐
matically controls vehicle speed on steep
downhill gradients. Without applying the
brakes, the vehicle moves at slightly more than
walking speed.
Hill Descent Control can be activated at
speeds below approx. 22 mph/35 km/h. When
driving downhill, the vehicle reduces its speed
to approx. walking speed and then keeps its
speed constant.
As long as there is active braking, the system
is on standby. The system does not brake the
vehicle during this time.
Only use HDC in low gears or in selector lever
position D or R.
Increasing or decreasing vehicle
speed
Specify desired speed in the range from ap‐
prox. 4 mph/6 km/h to approx. 15 mph/25 km/h
using the rocker reel of the cruise control on
the steering wheel. Vehicle speed can be
changed by lightly accelerating.
▷Press the rocker reel up to the point of re‐
sistance: the speed increases gradually.▷Press up the rocker reel past the point of
resistance: the speed increases while the
rocker reel is pressed.▷Press the rocker reel down to the point of
resistance: the speed decreases gradually.▷Press the rocker reel down past the point
of resistance: when driving forward, the
speed decreases to approx.
6 mph/10 km/h; when reversing, the speed
decreases to approx. 4 mph/6 km/h.
Activating HDC
Press button; the LED above the button
lights up.
Deactivating HDC Press button again and the LED goes
out. HDC is automatically deactivated
above approx. 37 mph/60 km/h.

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

Radar sensor
A radar sensor is located in the front bumper for detecting vehicles on the road ahead of the

General information
Depending on the driving settings, the features
of the cruise control can change in certain

conditions make it impossible to drive at a con‐
stant speed, e.g.:▷On winding roads.▷In heavy traffic.▷On slippery roads, in fog, snow or rain, or
on a loose road surface.
Otherwise, you could lose control of the vehi‐
