Active Blind Spot Detection
The concept
Two radar sensors below the rear bumper mon‐
itor the area behind and next to the vehicle at
speeds above approx. 30 mph/50 km/h.
The system indicates whether there are vehicles
in the blind spot, arrow 1, or approaching from
behind on the adjacent lane, arrow 2.
The lamp in the exterior mirror housing lights up
dimly.
Before you change lanes after setting the turn
signal, the system issues a warning in the situa‐
tions described above.
The lamp in the housing of the exterior mirror
flashes and the steering wheel vibrates.
Notes Personal responsibility
The system does not serve as a substitute
for the driver's personal judgment of the traffic
situation.
Be aware of the traffic situation and the vehicle's
surroundings at all times, otherwise an accident
is still possible despite all warnings.◀

Active Protection
General information
The Active Protection safety package consists
of systems that are independent of each other:
▷PreCrash▷PostCrashPreCrash
The concept
The system is used to detect critical driving sit‐
uations that might lead to an accident. In these
situations, preventative protection measures
are automatically undertaken to minimize the
risk in the event of an accident as much as pos‐
sible.
Critical driving situations may include:▷Full brake applications.▷Severe understeering.▷Severe oversteering.
If the vehicle includes the collision warning or
collision warning with braking feature, impend‐
ing collisions with vehicles driving ahead or
stopped in front of you can also be detected
within the system's range.
Personal responsibility
The system cannot serve as a substitute
for the driver's personal judgment of the traffic
situation. The system may not always detect
critical situations reliably and in a timely manner.
Adapt speed to traffic situation and drive alertly;
otherwise, a risk to safety may result.◀
Function
After the safety belt is buckled, the front belts
are automatically pretensioned once after the
vehicle is driven is away.
In critical driving situations, the following indi‐
vidual functions become active as needed:
▷The front belts are automatically preten‐
sioned.▷Automatic closing of the windows.▷Automatic closing of the glass sunroof.▷Automatic Positioning of the backrest for
the front passenger seat.
After a critical driving situation without an acci‐
dent, the front belts are loosened again. All other
systems can be restored to the desired setting.

Driving stability control systemsVehicle equipment
All standard, country-specific and optional
equipment that is offered in the model series is
described in this chapter. Therefore, equipment
is also described that is not available in a vehicle,
e. g., because of the selected optional equip‐
ment or country variant. This also applies for
safety-related functions and 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 107.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 or when a trailer
is being used, 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.◀

Indicator/warning lampsThe indicator lamp flashes: DSC con‐
trols the drive forces and brake forces.
The indicator lamp lights up: DSC has
failed.
Deactivating DSC: DSC OFF
When DSC is deactivated, driving stability is re‐
duced during acceleration and when driving in
bends.
Stabilizing interventions by the Integral Active
Steering system are only performed by the rear
axle steering.
To increase vehicle stability, activate DSC again
as soon as possible.
Deactivating DSC Press and hold the button, but not lon‐
ger than approx. 10 seconds, until the
indicator lamp for DSC OFF lights up in the in‐
strument cluster and DSC OFF is displayed.
The DSC system is switched off.
Activating DSC Press the button.
DSC OFF and the DSC OFF indicator
lamp go out.
Indicator/warning lamps
When DSC is deactivated, DSC OFF is dis‐
played in the instrument cluster.
The indicator lamp lights up: DSC is de‐
activated.DTC Dynamic Traction
Control
The concept
The DTC system is a version of the DSC in which
forward momentum is optimized.
The system ensures maximum forward momen‐
tum on special road conditions, e.g., unplowed
snowy roads, but driving stability is limited.
It is therefore necessary to drive with appropri‐
ate caution.
You may find it useful to briefly activate DTC un‐
der the following special circumstances:▷When driving in slush or on uncleared,
snow-covered roads.▷When rocking the vehicle or driving off in
deep snow or on loose surfaces.▷When driving with snow chains.
Deactivating/activating DTC Dynamic
Traction Control
Activating the Dynamic Traction Control DTC
provides maximum traction on loose ground.
Driving stability is limited during acceleration
and when driving in bends.
Activating DTC Press the button.
TRACTION is displayed in the instru‐
ment cluster and the indicator lamp for DSC
OFF lights up.
Deactivating DTC Press the button again.
TRACTION and the DSC OFF indicator
lamp go out.
Indicator/warning lamps
When DTC is activated, TRACTION is displayed
in the tachometer.
Seite 120ControlsDriving stability control systems120
Online Edition for Part no. 01 40 2 917 522 - II/13
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 down‐
hill 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 ap‐
prox. 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 ve‐
hicle during this time.
Use HDC in low gears or in transmission position
D or R only.
Increasing or decreasing vehicle speed
Specify desired speed in the range from approx.
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 up the rocker switch 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 down the rocker switch to the point of
resistance: the speed decreases gradually.▷Press down the rocker switch past the point
of resistance: when driving forward, the
speed decreases to approx. 6 mph/10 km/h;
when reversing, the speed decreases to ap‐
prox. 4 mph/6 km/h.
Activating HDC
Press the button; the LED above the but‐
ton lights up.
Deactivating HDC Press the button again and the LED goes
out. HDC is automatically deactivated
above approx. 37 mph/60 km/h.
Seite 121Driving stability control systemsControls121
Online Edition for Part no. 01 40 2 917 522 - II/13
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 203.
Programs
The system offers several different programs.
The programs can be selected via the Driving
Dynamics Control, refer to page 123.
SPORT
Consistently sporty tuning of the Integral Active
Steering for greater driving agility.
COMFORT

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.
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
