lity

In critical situations, the system can make tar-
geted corrections to the steering angle pro-
vided by the driver and thus stabilize the vehicle
before the driver intervenes. This stabilizing
intervention is simultaneously deactivated
when DSC is switched off, refer to page

81

.

Malfunction

The warning lamps come on. Active
steering is malfunctioning or is tem-
porarily deactivated. At low speeds,
greater steering wheel movements

are required, whereas at higher speeds the
vehicle reacts more sensitively to steering
wheel movements. The stability-enhancing
feature may also be deactivated. Drive cau-
tiously and think well ahead.

Deactivation

Active steering is deactivated to perform an ini-
tialization. A message indicates that the feature
is deactivated. Initialization may take several
minutes.
If the message does not disappear during the
current trip, have the system checked.

Defect

If there is a defect, a corresponding text mes-
sage appears. Have the system checked.

Servotronic*

The concept

The Servotronic varies the steering force
required to turn the wheels relative to the vehi-
cle speed.
At low speeds, the steering force is strongly
assisted, i.e. less force is needed for steering.
As the vehicle speed increases, the steering
assisting power is reduced.
This system functions automatically.

Malfunctions

Malfunctions are displayed via Check Control,
refer to page
