Active Blind Spot Detection
The concept
Two radar sensors below the rear bumper
monitor the area behind and next to the vehicle
at speeds above approx. 30 mph/50 km/h.
The system indicates whether there are vehi‐
cles in the blind spot, arrow 1, or approaching
from behind on the adjacent lane, arrow 2.
The lamp in the exterior mirror housing is dim‐
med.
Before you change lanes after setting the turn
signal, the system issues a warning in the sit‐
uations described above.
The lamp in the exterior mirror housing flashes
and the steering wheel vibrates.
Hints Personal responsibility
The system does not serve as a substi‐
tute for the driver's personal judgment of the
traffic situation.
Be aware of the traffic situation and the vehi‐
cle's surroundings at all times, otherwise acci‐
dents are still possible despite all warnings.◀

A recommendation to take a break is displayed
only once during an uninterrupted trip.
After a break, another recommendation to take
a break cannot be displayed until after approxi‐
mately 45 minutes.
System limits
The function may be limited in the following
situations, for instance, and will either output
an incorrect warning or no warning at all:▷When the clock is set incorrectly.▷When the vehicle speed is mainly below
about 43 mph/70 km/h.▷With a sporty driving style, such as during
rapid acceleration or when cornering fast.▷In active driving situations, such as when
changing lanes frequently.▷When the road surface is poor.▷In the event of strong side winds.
PreCrash
The concept With this system critical driving situations that
might result in an accident can be detected
above a speed of approx. 20 mph/30 km/h. In these situations, preventive measures are au‐
tomatically taken to minimize the risk of an ac‐
cident as much as possible.
Critical driving situations may include:
Emergency stop.
If the vehicle includes the front-end collision
warning or front-end collision warning with
braking feature, impending collisions with vehi‐
cles driving ahead or stopped in front of you
can also be detected within the system's
range.
Note
Personal responsibility
The system cannot possibly serve as a
substitute for the driver's personal judgment of
the traffic situation. The system may not al‐
ways 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.▷For vehicles equipped with power backrest
adjustment: 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.
If the belt tension does not loosen automati‐
cally, stop the vehicle and unbuckle the belt
using the red button in the buckle. Fasten the
belt before continuing on your trip.
PostCrash
In the event of an accident, the system can
bring the car to a halt automatically without in‐
tervention by the driver in certain situations.
This can reduce the risk of a further collision
and the consequences thereof.
Depressing the brake pedal can cause the ve‐
hicle to brake harder. This interrupts automatic
braking. Destepping on the gas pedal also in‐ terrupts automatic braking.

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.Seite 129Driving stability control systemsControls129

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 130ControlsDriving stability control systems130

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, 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 206, rear wheel steering is deactivated.
Programs The system offers several different programs.
Select the programs via the Driving Dynamics
Control, refer to page 132.
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.
