Active Steering Assist is only available up to a
speed of 130 mph (210 km/h). The system helps
you to stay in the center of the lane by means of
moderate steering interventions. Depending on
the speed driven, Active Steering Assist uses the
vehicles ahead and lane markings as a reference.
%
Depending on the country, in the lower speed
range Active Steering Assist can use the sur-
rounding tra c as a reference. If necessary,
Active Steering Assist can then also provide
assistance when driving away from the center
of the lane, for example, to form a rescue
lane.
If the detection of lane markings and vehicles
ahead is impaired, Active Steering Assist switches
to passive mode. The system provides no support
in this case.
