With side collision warning
If in the speed range up to 130 mph/210 km/h a
lane marking is crossed, the system intervenes
with a brief active steering intervention in addi‐
tion to vibrating. The steering intervention helps
keep the vehicle in the lane. The steering inter‐
vention can be noticed on the steering wheel
and can be manually overridden at any time.
With trailer towing
If the trailer power socket is in use, for instance
during operation with trailer or bicycle rack, no
steering intervention takes place.
End of warning
The warning is canceled in the following situa‐
tions:
▷ Automatically after approx. 3 seconds.
▷ When returning to your own lane.
▷ When braking hard.
▷ When using the turn signal.
▷ If DSC Dynamic Stability Control intervenes.
