Active Steering Assist
Function of Active Steering Assist
Active Steering Assist is only available up to a
speed of 210 km/h. The system helps you to
stay in the centre of the lane by means of mod‐
erate steering interventions. Depending on the
speed driven, Active Steering Assist uses the
vehicles ahead and lane markings as a refer‐
ence.
% Depending on the country, in the lower
speed range Active Steering Assist can use
the surrounding traffic as a reference. If nec‐
essary, Active Steering Assist can then also
provide assistance when driving outside the
centre 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.
