Steering assistance with brake intervention
Intervention with steering assistance and braking.
Brake intervention helps in situations where
steering assistance alone is not sufficient. The
brake force is adapted automatically depending
on the situation at the time of road run-off.

Steering assistance upon risk of
run-off
Steering assistance has a number of subfunc-
tions. Steering assistance in the event of run-off
risk can help the driver and reduce the risk of
the car accidentally leaving the road by actively
steering the car back onto the road.
The function is active within the speed range
65-140 km/h (40-87 mph) on roads with clearly
visible lane markings/lines.
A camera scans the edges of the road and the
painted side markings. If the car is about to leave
the side of the road, the car is steered back onto
the road and if the steering intervention is not
enough to avoid run-off, the brakes are also acti-
vated.
However, the function does not intervene with
either steering assistance or brake intervention if
the direction indicators are used. And if the func-
tion detects that the driver is actively driving the
car, activation of the function will be delayed.
After automatic engagement, the driver display
indicates that this has occurred via a text mes-
sage:
