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

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.
