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:
- Collision avoidance assistance – Automatic intervention
Warning
- The "Steering assistance at risk of run-off" subfunction is supplementary driver support intended to help improve driving safety – it cannot handle all situations in all traffic, weather and road conditions.
- The function cannot detect barriers, rails or similar obstacles at the side of the road.
- "Steering assistance at risk of run-off" is not a substitute for the driver's attention and judgment. The driver is always responsible for ensuring the vehicle is driven in a safe manner, at the appropriate speed, with an appropriate distance to other vehicles, and in accordance with current traffic rules and regulations.
