Assistance at risk of run-off

Assistance at risk of collision1 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 has two levels for intervention:
  • Steering assistance only
  • Steering assistance with brake intervention
PS2-2007-Lane Keeping Aid safety side edges 1
Intervention with steering assistance
PS2-2007-Lane Keeping Aid safety side edges 2
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.

The function is active within the speed range 65-140 km/h (40-87 mph) on roads with clearly visible lane markings/lines.

The car's camera unit 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 activated.

However, the function does not intervene with either steering assistance or brake intervention if the direction indicators are used. If the function detects that the driver is actively driving the car, activation of the function will be delayed.
