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, for
example, in curves, the steering angle is in‐
creased, 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, for example, when braking where road
conditions differ on the left and right sides of
the vehicle.
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
Information When snow chains are in use, refer to
page 216, rear wheel steering is deactivated.
Programs
The system offers several different programs.
Select the programs via the Driving Dynamics
Control, refer to page 137.
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 conceptThe 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.

Driving comfortVehicle 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 conceptUsing this system, a desired speed and a dis‐
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 vehicles ac‐
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.
The distance can be adjusted in several steps.
For safety reasons, it depends on the repective
speed.
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.
General information
Depending on the driving settings, the features of the cruise control can change in certain
areas.Information
WARNING
The system does not release 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 intervene in the re‐
spective situations.◀
WARNING
An unsecured vehicle can begin to move
and possibly 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 downhill slope,
turn the front wheels in the direction of the
curb.▷On uphill grades or on a downhill slope,
also secure the vehicle, e.g., with a wheel
chock.◀
WARNING
The desired speed can be incorrectly ad‐
justed or called up by mistake. There is risk of
an accident. Adjust the desired speed to the
traffic conditions. Watch traffic closely and ac‐
tively intervene in the respective situations.◀
WARNING
Risk of accident due to too high speed
differences to other vehicles, e.g., in the fol‐
lowing situations:
▷When fast approaching a slowly moving
vehicle.▷Suddenly swerving vehicle onto the own
lane.Seite 141Driving comfortControls141

▷When fast approaching standing vehicles.
There is a risk of injury or danger to life. Watch
traffic closely and actively intervene in the re‐
spective situations.◀

following situations:
▷When the driver applies the brakes.▷When selector lever position D is disen‐
gaged.▷When DTC is activated or DSC is deacti‐
vated.▷When DSC is actively controlling stability.▷When SPORT+ is activated with Driving
Dynamics Control.▷If the safety belt and the driver's door are
opened while the vehicle is standing still.▷If the system has not detected objects for
an extended period, for example, on a road
with very little traffic without curb or
shoulder markings.▷If the detection range of the radar is dis‐
rupted, for example, by dirt or heavy fog.▷After a longer stationary period when the
vehicle has been braked to a stop by the
system.Setting the speed
Maintaining/storing the speed
Press the rocker switch while the system is in‐
terrupted.
When the system is switched on, the current
speed is maintained and stored as the desired
speed.
The stored speed is displayed in the speedom‐
eter and briefly in the instrument cluster, refer
to page 144.
DSC will be switched on if needed.
The speed can also be stored bypressing 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.

Information WARNING
The system does not release from the
personal responsibility. Due to the system lim‐
its, braking can be late. There is risk of acci‐
dents or risk of property damage. Be aware to
the traffic situation at all times. Adjust the dis‐
tance to the traffic and weather conditions and
maintain the prescribed safety distance, possi‐
bly by braking.◀

tance, refer to page 145.
Continuing cruise control
General information An interrupted cruise control can be continued
by calling up the stored speed.
In the following cases, the stored speed value
is deleted and cannot be called up again:▷When the system is switched off.▷When the ignition is switched off.
Information
Make sure that the difference between current
speed and stored speed is not too large before
calling up the stored speed. Otherwise, unin‐
tentional braking or accelerating may occur.
Calling up stored speed and distance Press button with the system
switched on.
