Assistance at risk of run-off

Assistance at risk of collisionCollision Avoidance 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

Intervention with steering assistance

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 lane 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, there is no intervention from the function 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.

When the function intervenes, a message is shown in the driver display.

Warning

Warnings and steering assistance due to an impending collision with an oncoming vehicle always come very late.

Note

This function uses the car's camera and radar units, which have certain general limitations.
