The function is active at speeds between65-140 km/h (40-87 mph) on roads with clearlyvisible traffic lane markings/lines.
The system uses a camera to monitor the edgesof 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 backonto the road. If this is not sufficient to keep thevehicle on the road, the brakes will also beapplied.
However, the function will not provide eithersteering assistance or braking if the turn signal isused. The function will also not be activated if itdetects 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. The driver is alwaysresponsible for ensuring the vehicle isdriven in a safe manner, at the appropri-ate speed, with an appropriate distance toother vehicles, and in accordance withcurrent traffic rules and regulations.

winter driving conditions
narrow roads
poor road surfaces
a very sporty driving style
bad weather with reduced visibility
roads with indistinct or no lane markings
sharp edges or lines other than the lane'sside markings
when the power steering works at reducedpower, e.g. during cooling due to overheating(see section “Speed-dependent steeringforce”).

NOTE
The function uses the vehicle's combinedcamera and radar unit, which has certain gen-eral limitations; see sections "Camera limita-tions" and "Radar sensor limitations".
