Warning with braking function
Display
If a collision with a person detected in this way
is imminent, a warning symbol appears on the
instrument cluster and in the Head-up Display.
The red symbol is displayed and a sig‐
nal sounds.
With instrument display: The red sym‐
bol is displayed and a signal sounds.
Intervene immediately by braking or make an
evasive maneuver.
Braking intervention
The warning prompts the driver himself/herself
to react. During a warning, the maximum brak‐
ing force is used. Premise for the brake boos‐
ter is sufficiently quick and hard stepping on
the brake pedal. The system can assist with
some braking intervention if there is a risk of a
collision. At low speeds vehicles may thus
come to a complete stop.
The braking intervention is executed only if ve‐
hicle stability has not been restricted, e.g. by
deactivating the DSC Dynamic Stability Con‐
trol.
The braking intervention can be interrupted by
stepping on the accelerator pedal or by ac‐
tively moving the steering wheel.
Object detection can be restricted. Limitations
of the detection range and functional restric‐
tions are to be considered.
System limits
Information WARNING
The system can react incorrectly or not
at all due to the system limits. There is risk of
accidents or risk of property damage. Observe
the information regarding the system limits
and actively intervene, if needed.◀
Detection range
The detection potential of the camera is lim‐
ited.
Thus a warning might not be issued or be is‐
sued late.
E. g. the following situations may not be de‐
tected:▷Partially covered pedestrians.▷Pedestrians that are not detected as such
because of the viewing angle or contour.▷Pedestrians outside of the detection range.Seite 122ControlsSafety122

Driving stability control systemsVehicle features and optionsThis chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are not
necessarily available in your car, e. g., due to
the selected options or country versions. This
also applies to safety-related functions and
systems. The respectively applicable country
provisions must be observed when using the
respective features and systems.
Anti-lock Braking System
ABS
ABS prevents locking of the wheels during
braking.
The vehicle contains its steering power 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 greatest possible
braking force boost. It reduces the braking dis‐
tance to a minimum during emergency stop.
This system utilizes all of the benefits provided
by ABS.
Do not reduce the pressure on the brake pedal
for the duration of the emergency stop.
Adaptive brake assistant In combination with the Active Cruise Control,
this system ensures that the brakes respond
even more rapidly when braking in critical sit‐
uations.Drive-off assistant
The concept This system supports driving off on inclines.
The parking brake is not required.
Driving off with the drive-off assistant1.Hold the vehicle in place with the foot
brake.2.Release the foot brake and drive off 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.
DSC Dynamic Stability
Control
The concept
Within the physical limits, the system helps to
keep the vehicle on a steady course by reduc‐
ing engine speed and by applying brakes to
the individual wheels.
General information
Dynamic Stability Control detect for example
the following unstable driving conditions:
▷Fishtailing, which can lead to oversteering.▷Loss of traction of the front wheels, which
can lead to understeering.
Dynamic Traction Control DTC, refer to
page 134, is a version of the DSC where for‐
ward momentum is optimized.
Information The laws of physics cannot be repealed, not
even with DSC.

▷When freeing vehicle from deep snow or
driving off from loose grounds.▷When driving with snow chains.
Deactivating/activating DTC Dynamic
Traction Control
Activating DTC Press button.
TRACTION is displayed in the instru‐
ment cluster and the indicator lamp for DSC
OFF lights up.
Deactivating DTC Press button again.
TRACTION and the DSC OFF indica‐
tor lamp go out.
Indicator/warning lights
If DTC is activated, TRACTION is displayed in
the instrument cluster.
The indicator lamp lights up: DTC Dy‐
namic Traction Control is activated.
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. It the brakes are actively ap‐
plied, the system distributes force according to
the traction.
Vehicle stability and maneuverability are im‐
proved on downhill gradients.
Hill Descent Control can be activated at
speeds below approx. 22 mph/35 km/h. When
driving downhill, the vehicle reduces its speed
and then keeps its speed constant.
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 switch of the cruise control on
the steering wheel. Vehicle speed can be
changed by lightly accelerating.▷Press the rocker switch up 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.▷Press the rocker switch down to the point
of resistance: the speed decreases gradu‐
ally.▷Press the rocker switch 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 135Driving stability control systemsControls135

COMFORT/ECO PROBalanced tuning.
COMFORT+ Comfort-oriented tuning of the shock absorb‐
ers 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, for
example, in curves, the steering angle is in‐
creased, 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, for example, when braking where road
conditions differ on the left and right sides of
the vehicle.
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
Information When snow chains are in use, refer to
page 216, rear wheel steering is deactivated.
Programs
The system offers several different programs.
Select the programs via the Driving Dynamics
Control, refer to page 137.
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 conceptThe 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.

Active Cruise Control with Stop&Go function, ACC
The conceptUsing this system, a desired speed and a dis‐
tance to a vehicle ahead can be adjusted using
the buttons on the steering wheel.
The system maintains the desired speed on
clear roads. For this purpose, the vehicles ac‐
celerates or brakes automatically.
If a vehicle is driving ahead of you, the system
adjusts the speed of your vehicle within the
given system limits so that the set distance to
the vehicle ahead is maintained.
The distance can be adjusted in several steps.
For safety reasons, it depends on the repective
speed.
If the vehicle ahead of you brakes to a halt, and
then proceeds to drive again within a brief pe‐
riod, the system is able to detect this within the
given system limits.
General information
Depending on the driving settings, the features of the cruise control can change in certain
areas.Information
WARNING
The system does not release from the
personal responsibility to correctly assess the
traffic situation. Based on the limits of the sys‐
tem, it cannot independently react to all traffic
situations. There is risk of an accident. Adjust
the driving style to the traffic conditions. Watch
traffic closely and actively intervene in the re‐
spective situations.◀
WARNING
An unsecured vehicle can begin to move
and possibly roll away. There is risk of an acci‐
dent. Before exiting, secure the vehicle against
rolling.
In order to ensure that the vehicle is secured
against rolling away, observe the following:▷Set the parking brake.▷On uphill grades or on a downhill slope,
turn the front wheels in the direction of the
curb.▷On uphill grades or on a downhill slope,
also secure the vehicle, e.g., with a wheel
chock.◀
WARNING
The desired speed can be incorrectly ad‐
justed or called up by mistake. There is risk of
an accident. Adjust the desired speed to the
traffic conditions. Watch traffic closely and ac‐
tively intervene in the respective situations.◀
WARNING
Risk of accident due to too high speed
differences to other vehicles, e.g., in the fol‐
lowing situations:
▷When fast approaching a slowly moving
vehicle.▷Suddenly swerving vehicle onto the own
lane.Seite 141Driving comfortControls141
