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.
In difficult conditions (e.g. unclear roads, lane
narrowing, 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.

speed range Active Steering Assist can use

essary, Active Steering Assist can then also
provide assistance when driving away from
the center of the lane to form a rescue lane,
for example.
When the system is actively steering, the à
symbol is shown in green in the multifunction
