System limits
Route-based speed adaptation does not take
right of way regulations into account. The driver
is responsible for complying with road traffic
regulations and driving at a suitable speed.
The speed adaptation made by the system may
not always be suitable, particularly in the follow‐
ing situations:
R
the road's course not clearly visible
R
road narrowing
R
varying maximum permissible speeds in indi‐
vidual lanes, for example at toll stations
R
wet road surfaces, snow or ice
R
when towing a trailer
In these situations the driver must intervene
accordingly.
& WARNING Risk of accident in spite of
route-based speed adaptation
Route-based speed adaptation can malfunc‐
tion or be temporarily unavailable in the fol‐
lowing situations:
R
If the driver does not follow the calcula‐
ted route
R
If map data is not up-to-date or available
R
In the event of roadworks
R
In bad weather or road conditions
R
If the accelerator pedal is depressed
R
In the event of electronically displayed
speed limitations

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.
