xDrive
xDrive is the all-wheel-drive system of the 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.Seite 165Driving stability control systemsControls165

A vehicle has been detected
ahead of you. The system
maintains the set distance to
the vehicle in front.Vehicle symbol flashes:
The conditions are not ade‐
quate for the system to work.
The system was deactivated
but applies the brakes until you
actively resume control by
pressing on the brake pedal or
accelerator pedal.The vehicle symbol and dis‐
tance bars flash red and an
acoustic signal sounds:
You are requested to intervene
by braking or make an evasive
maneuver.
Displays in the Head-up Display
With Active Cruise control, some system infor‐
mation can also be displayed in the Head-up
Display.
The symbol is displayed on the Head-
up Display if the set desired speed is
reached.
Distance information The symbol is displayed when the dis‐
tance from the vehicle traveling ahead
is too short.
The distance information is active under the
following circumstances:
▷Active Cruise Control switched off.▷Display in the Head-up Display selected,
refer to page 126.▷Distance too short.▷Speed greater than approx.
40 mph/70 km/h.
System limits
Speed range The system is best used on well-constructedroads.
The minimum speed that can be set is
20 mph/30 km/h.
The maximum speed that can be set is
115 mph/180 km/h.
The system can also be activated when sta‐
tionary.
Comply with the legal speed limit in every sit‐
uation when using the system.
Detection range
The detection capacity of the system and the
automatic braking capacity are limited.
Two-wheeled vehicles for instance might not
be detected.
Deceleration
The system also does not decelerate in the fol‐
lowing situations:
▷For pedestrians or similar slow-moving
road users.▷For red traffic lights.▷For cross traffic.▷For oncoming traffic.Seite 173Driver assistance systemsControls173

Display
Signal tones When approaching an object, an intermittent
sound indicates the position of the object. E. g.
if an object is detected to the left rear of the
vehicle, a signal tone sounds from the left rear
speaker.
The shorter the distance to the object, the
shorter the intervals.
If the distance to a detected object is less than
approx. 10 in/25 cm, a continuous tone is
sounded.
If there are objects in front of and behind the
vehicle at the same time, with a distance
smaller than approx. 10 in/25 cm, an alternat‐
ing constant tone will sound.
The interval tone and constant tone are
switched off if the selector lever position P is
engaged.
The interval tone is switched off after a short
time when the vehicle is stationary.
Volume
The ratio of the PDC signal tone volume to the
entertainment volume can be adjusted.

Visual warning
The approach of the vehicle to an object is
shown on the Control Display. Objects that are
farther away are already displayed on the Con‐
trol Display before a signal sounds.
The display appears as soon as PDC is acti‐
vated.
The range of the sensors is represented in the
colors green, yellow and red.
Pathway lines are faded in for better estimation
of the required space.

Functional limitations
The system may not be fully functional in the
following situations:▷On bumpy road surfaces such as gravel
roads.▷On slippery ground.▷On steep uphill or downhill grades.▷With accumulations of leaves/snow in the
parking space.▷With a mounted emergency wheel.▷In case of changes to an already-measured

Limits of ultrasonic measurement
Ultrasonic measuring might not function under
the following circumstances:
▷For small children and animals.▷For persons with certain clothing, e.g.
coats.▷With external interference of the ultra‐
sound, e.g. from passing vehicles or loud
machines.▷When sensors are dirty, iced over, dam‐

It can happen that parking spaces are detected
that are not suitable or suitable parking spaces
are not detected.
Malfunction

checked.
Cross traffic warning The concept
Two radar sensors in the rear bumper monitor
the area behind the vehicle.
At blind driveways or when driving out of diag‐
onal parking spaces, approaching cross traffic
is earlier detected by the system than possible
from the driver's seat.
The system indicates approaching traffic.
The lamp in the exterior mirror lights up, a sig‐
nal tone may sound, and the respective indica‐
tor is called up on the Control Display.
With the respective equipment variant, the
traffic area in front of the vehicle is monitored
as well. Two additional radar sensors are lo‐
cated in the front bumpers.

desired function on the hand-held trans‐
mitter.5.Release both buttons as soon as the inte‐
rior mirror LED flashes more rapidly or
lights up continuously. The LED flashing
more rapidly or being continuously light up
indicates that the button on the interior

If the LED does not flash faster after at
least 60 seconds, change the distance and
repeat the step. Several more attempts at
different distances may be necessary. Wait
at least 15 seconds between attempts.

WARNING
Body parts can be jammed when operat‐
ing remote-controlled systems, e.g. the garage
door, using the universal garage door opener. There is risk of injuries or risk of property dam‐
age. Make sure that the area of movement of
the respective system is clear during program‐
ming and operation. Also follow the safety in‐
structions of the hand-held transmitter.◀
The system, such as the garage door, can be
operated using the button on the interior mirror
