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.◀

Display
Lamp in the exterior mirror housing
Information stage
The dimmed lamp in the exterior mirror hous‐
ing indicates when there are vehicles in the
blind spot or approaching from behind.
Warning If the turn signal is set while a vehicle is in the
critical zone, the steering wheel vibrates briefly
and the lamp in the exterior mirror housing
flashes brightly.
The warning stops when the turn signal is
switched off, or the other vehicle leaves the
critical zone.
System limits
The system may not be fully functional in the
following situations:
▷When a vehicle is approaching at a speed
much faster than your own.▷In heavy fog, rain or snowfall.▷In tight curves or on narrow lanes.▷If the bumper is dirty or iced up, or covered
with stickers.
A Check Control message is displayed when
the system is not fully functional.
For US owners only The transmitter and receiver units comply with
part 15 of the FCC/Federal Communication
Commission regulations. Operation is gov‐
erned by the following:
FCC ID:▷NBG009014A.
Compliance statement:

Rules. Operation is subject to the following
two conditions:
▷This device may not cause harmful inter‐
ference, and▷this device must accept any interference
received, including interference that may

▷During normal brake application, the outer
brake lights light up.▷During heavy brake application, the inner
brake lights light up in addition.
Active Protection
General information
The Active Protection safety package consists
of systems that are independent of each other:

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.
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 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 130ControlsDriving stability control systems130

Before leaving the vehicle, secure it
against moving on its own.
Before leaving the vehicle with the engine run‐
ning: set the parking brake and ensure that the
Steptronic transmission is in position P. Other‐
wise, the vehicle may begin to move.◀

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.

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.
The parking assistant calculates the best pos‐
sible parking line and takes control of steering
during the parking procedure.
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 145.
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.◀
Curbs
The parking assistant may steer the vehi‐
cle over or onto curb if need be.
Therefore, always be alert and ready to inter‐
vene; otherwise, the wheels, tires, or the vehi‐
cle may become damaged.◀
An engine that has been switched off by the
Auto Start Stop function is restarted automati‐
cally when the parking assistant is activated.

Parked-car ventilation/
heating
The concept The parked-car ventilation ventilates the vehi‐
cle interior and lowers its temperature, if
needed.
The parked-car heating warms the vehicle in‐
terior, making snow and ice easier to remove.
With the ignition switched off, the air is auto‐
matically routed to the windshield, to the side
windows, and into the footwell.
The systems can be switched on and off di‐
rectly or by using two preset reel-on times.
They remain switched on for 30 minutes.
