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.Seite 137Driving stability control systemsControls137

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 inter‐
venes, e.g., when braking where road condi‐
tions differ on the left and right sides of the ve‐
hicle.
InitializingIn 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 sev‐
eral 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
steering wheel approx. 6 times or if the
steering wheel is at an angle.
Using snow chains
Note When snow chains are in use, refer to
page 225, rear wheel steering is deactivated.
Programs The system offers several different programs.
Select the programs via the Driving Dynamics
Control, refer to page 139.
SPORT
Consistently sporty tuning of the Integral Ac‐
tive Steering for greater driving agility.
Malfunction In the event of a malfunction, the steering
wheel must be turned further, while the vehicle
responds more sensitively to steering wheel
movements in the higher speed range.
The stability-enhancing intervention may be
deactivated.
Proceed cautiously and drive defensively.
Have the system checked.
Driving Dynamics Control
The concept The Driving Dynamics Control can be used to
adjust the driving dynamics of the vehicle. For
this purpose various programs are available for
selection that are activated via the two buttons
of the Driving Dynamics Control and the DSC
OFF-button.

Radar sensor
A radar sensor is located in the front bumper for detecting vehicles on the road ahead of the
vehicle.
A dirty or covered sensor may prevent the de‐
tection of vehicles.
▷If necessary, clean the radar sensor. Re‐
move layers of snow and ice carefully.▷Do not cover the view field of the radar
sensor.
Camera
The camera is found near the interior rearview
mirror.
Keep the windshield in the area behind the in‐
terior rearview mirror clean and clear.
A dirty or covered area in front of the interior
mirror may hinder the detection of vehicles.
If necessary, clean the area in front of the inte‐
rior mirror, e.g., carefully remove salt residue in
the winter.

and be ready to brake at all times; otherwise,
there is the risk of an accident.◀
Differences in speed
Large differences in speed relative to
other vehicles cannot be compensated by the
system such as in the following situations:
▷When fast approaching a slowly moving
vehicle.▷When another vehicle suddenly swerves
into the wrong lane.▷When stationary objects are approached at
high speed.◀

Cruise controlThe concept The system maintains a preset speed via the
buttons on the steering wheel. The system
brakes on downhill gradients if engine braking
is insufficient.
General information
Depending on the driving settings, the features
of the cruise control can change in certain
areas.
Hints Unfavorable conditions
Do not use the system if unfavorable
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‐
cle and cause an accident.◀

Parking assistant The concept
This system assists the driver in parking paral‐
lel to the road.
Ultrasound sensors measure parking spaces
on both sides of the vehicle.
Manual transmission:
The parking assistant calculates the best pos‐
sible parking line and takes control of steering
during the parking procedure.
Steptronic transmission:
The parking assistant calculates the best pos‐
sible parking line and during the parking proce‐
dure takes control of steering, the acceleration
and braking and if needed changes the gears.
Hold down the parking assistant button for the
duration of the parking procedure. At the end
of the parking procedure, the P selector lever
position is set.
When parking, also take note of the visual and
acoustic information and instructions issued
by the PDC, the parking assistant and the rear‐
view camera and react accordingly.
A component of the parking assistant is the
PDC Park Distance Control, refer to page 152.
Hints Personal responsibility
Even an active system does not relieve
the driver from personal responsibility while
driving.
Technically the system has its limits, it cannot
independently react to all traffic situations.
Monitor your driving, be on the alert, observe
the vehicle surroundings and other traffic and
react when needed - risk of accident.◀
Changes to the parking space
Changes to the parking space after it was
measured are not taken into account by the
system.
Therefore, always be alert and ready to inter‐
vene; otherwise, there is the risk of an acci‐
dent.◀
Transporting cargo
Cargo that extends beyond the perimeter
of the vehicle is not taken into account by the
system during the parking procedure.
Therefore, always be alert and ready to inter‐
vene; otherwise, there is the risk of an acci‐
dent.◀Seite 160ControlsDriving comfort160
