Active steering*<br />
Servotronic*<br />
The concept<br />
Active steering varies the turning angle of the<br />
front wheels in relation to steering wheel movements.<br />
It also varies the steering force required<br />
to turn the wheels depending on the speed at<br />
which you are driving.<br />
When you are driving in the low road speed<br />
range, e.g. in a town or when parking, the steering<br />
angle is increased, i.e. steering becomes<br />
very direct and less effort is required to turn the<br />
wheels. In the higher speed range, on the other<br />
hand, the steering angle is reduced as the<br />
speed increases. This improves the handling of<br />
your <strong>BMW</strong> over the entire speed range.<br />
In critical situations, the system can make targeted<br />
corrections to the steering angle provided<br />
by the driver and thus stabilize the vehicle<br />
before the driver intervenes. This stabilizing<br />
intervention is simultaneously deactivated<br />
when DSC is switched off, refer to page 81.<br />
Malfunction<br />
The warning lamps come on. Active<br />
steering is malfunctioning or is temporarily<br />
deactivated. At low speeds,<br />
greater steering wheel movements<br />
are required, whereas at higher speeds the<br />
vehicle reacts more sensitively to steering<br />
wheel movements. The stability-enhancing<br />
feature may also be deactivated. Drive cautiously<br />
and think well ahead.<br />
Deactivation<br />
Active steering is deactivated to perform an initialization.<br />
A message indicates that the feature<br />
is deactivated. Initialization may take several<br />
minutes.<br />
If the message does not disappear during the<br />
current trip, have the system checked.<br />
Defect<br />
If there is a defect, a corresponding message<br />
appears. Have the system checked.<br />
The concept<br />
The Servotronic varies the steering force<br />
required to turn the wheels relative to the vehicle<br />
speed.<br />
At low speeds, the steering force is strongly<br />
assisted, i.e. less force is needed for steering.<br />
As the vehicle speed increases, the steering<br />
assisting power is reduced.<br />
Malfunction<br />
Malfunctions are displayed via Check Control,<br />
