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, e.g.,
in curves, the steering angle is increased, 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, e.g., when braking where road condi‐
tions differ on the left and right sides of the ve‐
hicle.
Initializing
In 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
Note
When snow chains are in use, refer to
page 228, rear wheel steering is deactivated.
Programs
The system offers several different programs.
Select the programs via the Driving Dynamics
Control, refer to page 139.
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 concept
The 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.
