Run-Off Mitigation with steeringassistance
This sub-function is intended to help reduce the risk of the vehicle inadvertently running off theroad by actively steering the vehicle back ontothe road.
The function is active at speeds between 65-140 km/h (40-87 mph) on roads with clearlyvisible traffic lane markings/lines. The system uses a camera to monitor the edges of the road and the painted side marker lines. Ifthe 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 thevehicle. After the system has automatically intervened, this text message will appear in the instrumentpanel:
•
Collision avoidance assistance –Automatic intervention
WARNING
• The "Steering assistance at risk of run- off" subfunction is supplementary driversupport intended to help improve drivingsafety – it cannot handle all situations inall traffic, weather and road conditions.
• The function cannot detect barriers, railsor similar obstacles at the side of theroad.
• "Steering assistance at risk of run-off" isnot a substitute for the driver's attentionand judgment.
