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

Integral Active Steering The concept
Integral Active Steering is a combination of Ac‐
tive Steering and rear axle steering.
The system varies the steering angle of the
wheels in relation to the steering wheel move‐
ment.
Seite 166ControlsDriving stability control systems166
Online Edition for Part no. 0140 2 964 330 - VI/15
Page 167 of 314
With strong steering movements and low
speeds, e.g. when parking, the wheel angle is
magnified, that is, the steering is 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 rear wheels are turned in
the same direction as the front wheels.
In critical driving situations, the Integral Active
Steering can stabilize the vehicle through pur‐
poseful steering of the rear wheels before the
driver intervenes, e.g. in case of oversteering.
General information The system offers several different tunings.
These are assigned to the different driving
modes of the Driving Dynamics Control, refer
to page 110.
TuningDrive modeIntegral Active SteeringCOMFORT/E
CO PROcomfortable, for optimal
travel comfortSPORTdynamic, for greater agility
Using snow chains
Information When snow chains are in use, refer to
page 264, rear wheel steering is deactivated.
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.

Driver assistance systemsVehicle features and options
This 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.
Active Cruise Control with Stop & Go function, ACC
The concept
Use this system to select a desired speed that
the vehicle will maintain automatically on clear
roads.
To the extent possible, the system automati‐
cally adjusts the speed to a slower vehicle
ahead of you.
The distance that the vehicle maintains to the
vehicle ahead of you can be varied. For safety
reasons, it depends on the speed.
To maintain a certain distance, the system au‐
tomatically reduces the speed, applies the
brakes lightly, or accelerates again if the vehi‐
cle ahead begins moving faster.
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. Your own vehicle will
brake automatically and then accelerate again.
If the vehicle ahead of you drives away again
after a prolonged period, briefly press the ac‐
celerator pedal or press the appropriate button
to reactivate the system. The vehicle will auto‐
matically accelerate.As soon as the road is clear, the vehicle accel‐
erates to the desired speed.
Vehicles driving ahead are captured by a radar
sensor and a camera.
General information
Depending on the driving settings, the features
of the cruise control can change in certain
areas.
The desired speed is also maintained downhill,
but may not be maintained on uphill grades if
engine power is insufficient.
Due to the driving style that minimizes fuel
consumption in ECO PRO drive mode, the ve‐
hicle may drop below the set desired speed in
some situations, e.g. on uphill grades.
Information WARNING
The system does not relieve 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 interfere in the re‐
spective situations.◀
WARNING
An unsecured vehicle can put itself into
motion and 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 slope, turn the
front wheels in the direction of the curb.▷On uphill grades or on a slope, also secure
the vehicle, e.g. with a wheel chock.◀Seite 168ControlsDriver assistance systems168

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

Swerving vehicles
A vehicle driving in front of you is not detected
until it is completely within the same lane as
your vehicle.
If a vehicle driving ahead of you suddenly
swerves into your lane, the system may not be
able to automatically restore the selected dis‐
tance. This also applies to major speed differ‐
ences to vehicles driving ahead of you, e.g.,
when rapidly approaching a truck. When a ve‐
hicle driving ahead of you is reliably detected,
the system requests that the driver intervene
by braking and carrying out evasive maneu‐
vers, if needed.
WARNING
The system does not relieve 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 interfere in the re‐
spective situations.◀
Cornering
If the desired speed is too high for a curve, the
speed is reduced slightly, although curves can‐
not be anticipated in advance. Therefore, drive
into a curve at an appropriate speed.
In tight curves the system offers only restricted
detection where a vehicle ahead of you might
be detected late or not at all.
When you approach a curve the system may
briefly report vehicles in the next lane due to
the bend of the curve. If the system deceler‐
ates you may compensate it by briefly acceler‐
ating.
After releasing the gas pedal the system is re‐
activated and controls speed independently.
Driving away In some situations, the vehicle cannot drive off
automatically; for example:
▷On steep inclines.▷From behind bumps in the road.
In these cases, step on the accelerator pedal.

Weather
In the event of unfavorable weather and light conditions, e. g. if there is rain, snowfall, slush,
fog or glare, this may result in poorer recogni‐
tion of vehicles as well as short-term interrup‐
tions for vehicles that are already detected. Drive attentively, and react to the current trafficsituation. If necessary, intervene actively, e.g.
by braking, steering or evading.
Radar sensor
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:

system fails.
The function for detecting and responding
when approaching stationary vehicles may be limited in the following situations:
▷During calibration of the camera immedi‐
ately after vehicle delivery.▷If the camera is malfunctioning or dirty. A
Check Control message is displayed.
Cruise control
The 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.
The desired speed is also maintained downhill,
but may not be maintained on uphill grades if
engine power is insufficient.
Due to the driving style that minimizes fuel
consumption in ECO PRO drive mode, the ve‐
hicle may drop below the set desired speed in
some situations, e.g. on uphill grades.
Information WARNING
The use of the system can lead to an in‐
creased risk of accidents in the following situa‐
tions:
▷On winding roads.▷In heavy traffic.▷On slippery roads, in fog, snow or rain, or
on a loose road surface.
There is risk of accidents or risk of property
damage. Only use the system if driving at con‐
stant speed is possible.◀
