features
and
optionsThis chapter describes all standard, country-specific and optional features offered with theseries. It also describes features that are notnecessarily available in your vehicle, e. g., due
to the selected options or country versions.
This also applies to safety-related functions
and systems. When using these functions and systems, the applicable country provisions
must be observed.
Anti-lock
Braking
System
ABS
ABS prevents locking of the wheels during
braking.
The vehicle maintains its steering power even during full brake applications, thus increasing
active safety.
ABS is operational every time you start the en#j gine.
Brake
assistant When you apply the brakes rapidly, the system
automatically produces the greatest possible
braking force boost. It reduces the braking dis#j
tance to a minimum during emergency stop.
This system utilizes all of the benefits provided
by ABS.
Do not reduce the pressure on the brake pedal
for the duration of the emergency stop.
Adaptive
brake
assistant In combination with the Active Cruise Control,
this system ensures that the brakes respond
even more rapidly when braking in critical sit#j
uations.Drive-off
assistant
Concept
This system supports driving off on inclines.
Driving
away1.Hold the vehicle in place with the foot
brake.2.Release the foot brake and drive off with#j
out delay.
After the foot brake is released, the vehicle is held in place for approx. 2 seconds.
After the accelerator pedal is depressed, the
vehicle is held until it is driven off.
Depending on the vehicle loading, the vehicle
may roll back slightly.
DSC
Dynamic
Stability
Control
Concept Within the physical limits, the system helps to
keep the vehicle on a steady course by reduc#j
ing engine speed and by braking the individual
wheels.
General
information
Dynamic Stability Control detects, e.g., the fol#j lowing unstable driving conditions:
'yFishtailing, which can lead to oversteering.'yLoss of traction of the front wheels, which
can lead to understeering.
Safety
information
WARNING
The system does not release from the
personal responsibility to correctly assess the
traffic situation. Based on the limits of the sys#j

tem, it cannot independently react to all trafficsituations. There is a risk of an accident. Adjust
the driving style to the traffic conditions. Watch
traffic closely and actively intervene in the re#j
spective situations.'

You may find it useful to briefly activate DTC inthe following situations:'yWhen driving in slush or on uncleared,
snow-covered roads.'yWhen freeing vehicle from deep snow or driving off from loose ground.'yWhen driving with snow chains.

xDrive
xDrive is the all-wheel-drive system of the ve#j
hicle. The interaction of xDrive and DSC Dy#j
namic Stability Control further optimizes trac#j
tion and driving dynamics. xDrive variably
distributes the driving forces to the front and
rear axles as demanded by the driving situation
and road surface.
Integral
Active
Steering
Concept
Integral Active Steering is a combination of Ac#j tive Steering and rear axle steering.
The system varies the steering angle of the
wheels in relation to the steering wheel move#j
ment.
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#j
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#j
poseful steering of the rear wheels before the
driver intervenes, e.g., in case of oversteering.
General
information The system offers several different tunings.Seite 171Driving

Using
snow
chains
When snow chains are in use, refer to
page 277, 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 wheelmovements in the higher speed range.
The stability-enhancing intervention may bedeactivated.
Proceed cautiously and drive defensively. Have the system checked.

Cruise
controlConcept
Using this system, a desired speed can be ad#j justed using the buttons on the steering wheel.
The system maintains the desired speed. The system accelerates and brakes automaticallyas needed.
General
information
Depending on the vehicle setting, the cruise
control characteristic can change in certain ranges. For instance, the acceleration in ECOPRO driving mode is more gentle.
Safety
information WARNING
The system does not release from the
personal responsibility to correctly assess the

Switching
cruise
control
on/off
Switching
on Press button on the steering wheel.
The indicator lights in the instrument cluster
light up and the mark in the speedometer is set
to the current speed.
Cruise control is active. The current speed is
maintained and stored as desired speed.
DSC will be switched on, if needed.
Switching
off Press button on the steering wheel.
The displays go out. The stored desired speed is deleted.
Setting
the
speed
Maintaining
and
storing
the
speed
Press the rocker switch while the system is in#j terrupted.
When the system is switched on, the current
speed is maintained and stored as the desired
speed.
The stored speed is displayed, refer to
page 175, in the speedometer and briefly in
the instrument cluster.
DSC will be switched on, if needed.
The speed can also be stored by pressing a
button.
Press button.
Changing
the
speed
Press the rocker switch up or down repeatedly
until the desired speed is set.
If active, the displayed speed is stored and the vehicle reaches the stored speed when the
road is clear.
'yEach time the rocker switch is pressed to
the resistance point, the desired speed in#j
creases or decreases by 1 mph/1 km/h.'yEach time the rocker switch is pressed
past the point of resistance, the desired
speed increases or decreases by a maxi#j
mum of 5 mph/10 km/h.
The maximum speed that can be set de#j

ance point and holding it accelerates or de#j
celerates the vehicle without requiring
pressure on the accelerator pedal.
After the rocker switch is released, the ve#j
hicle maintains its final speed. Pressing the
switch beyond the resistance point causes
the vehicle to accelerate more rapidly.

An interrupted cruise control can be continued
by calling up the stored speed.
Make sure that the difference between current
speed and stored speed is not too large before calling up the stored speed. Otherwise, unin#jtentional braking or accelerating may occur.

System
limits
The desired speed is also maintained downhill. The speed may not be maintained on uphill
grades if the engine power is insufficient.
Due to the driving style that minimizes fuel
consumption in ECO PRO driving mode, the
vehicle may drop below the set desired speed
in some situations, e.g., on uphill grades.

Concept
Using this system, a desired speed and a dis#j
tance to a vehicle ahead can be adjusted using the buttons on the steering wheel.
The system maintains the desired speed on clear roads. For this purpose, the vehicle ac#j
celerates or brakes automatically.
If a vehicle is driving ahead of you, the system
adjusts the speed of your vehicle within the
given system limits so that the set distance to
the vehicle ahead is maintained.

General
information
A radar sensor is located in the front bumper and a camera on the interior mirror to detect
vehicles driving ahead of you.
Depending on the vehicle setting, the cruise
control characteristic can change in certain
ranges. For instance, the acceleration in ECO
PRO driving mode is more gentle.
The distance can be adjusted in several steps.
For safety reasons, it depends on the respec#j tive speed.
If the vehicle ahead of you brakes to a halt, and
then proceeds to drive again within a brief pe#j
riod, the system is able to detect this within the
given system limits.
Safety
information WARNING
