Intervention with steering assistance and braking.
Braking intervention assists in situations where
steering assistance alone is not sufficient. Brak-
ing force is automatically adapted according to
the situation at the moment the vehicle begins to
run off the road.

Run-Off Mitigation with steering
assistance
Steering assistance has several sub-functions.
Run-Off Mitigation with steering assistance can
help the driver and reduce the risk of the vehicle
inadvertently running off the road by actively
steering the vehicle back onto the road.
The function is active at speeds between
65-140 km/h (40-87 mph) on roads with clearly
visible traffic lane markings/lines.
The system uses a camera to monitor the edges
of the road and the painted side marker lines. If
the vehicle is about to cross the edge of the road,
the function will attempt to steer the vehicle back
onto the road. If this is not sufficient to keep the
vehicle on the road, the brakes will also be
applied.
However, the function will not provide either
steering assistance or braking if the turn signal is
used. The function will also not be activated if it
detects that the driver is actively operating the
vehicle.
After the system has automatically intervened,
this text message will appear in the instrument
panel:
