System limits
Route-based speed adaptation does not take
right of way rules into account. The driver is
responsible for complying with road traffic regu‐
lations and driving at a suitable speed.
In difficult conditions (e.g. unclear roads, narrow
lanes, wet road surfaces, snow or ice) or when
driving with a trailer, the speed adjustment made
by the system may not always be suitable. In
these situations the driver must intervene
accordingly.

Active Steering Assist
Function of Active Steering Assist
%
The following function is country-dependent
and only available in conjunction with the
Driving Assistance Package.
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.
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.
