Steering assistance at risk ofcollision
The
Collision avoidance assistance function
is intended to help the driver reduce the risk of the vehicle inadvertently veering from the trafficlane and/or colliding with another vehicle orobstacle by actively steering the vehicle backinto the lane and/or swerving out of the way.
Collision avoidance assistance consists of
three sub-functions:
• Run-Off Mitigation with steering assistance
• Steering assistance during collision risks from oncoming traffic
• Steering assistance during collision risks from behind
*
After the system has automatically intervened, this text message will appear in the instrumentpanel:
•
Collision avoidance assistance –Automatic intervention
NOTE
It is always the driver who must decide how much the vehicle should be in control – thevehicle can never take command.

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. 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.

Limitations of Run-Off Mitigationwith steering assistance
In certain demanding driving conditions, the function may not be able to properly assist thedriver. In these situations, it is recommendedthat it is turned off.
Examples of such situations include:
• road work
• 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's side markings
• when the power steering works at reducedpower - e.g. during cooling due to overheat-ing (see section "Speed-dependent steeringforce").
NOTE
The function uses the vehicle's camera unit, which has some general limitations – see thesection "Camera unit limitations".

The function is active at speeds between 60-140 km/h (37-87 mph) on roads with clearlyvisible traffic lane markings/lines. If your vehicle is starting to veer from your own lane and a vehicle is approaching from the oppo- site direction, this function can help the driversteer the vehicle back into its own lane. However, the function will
not provide steering
assistance if the turn signal is used. The functionwill also not be activated if it detects that thedriver is actively operating the vehicle. After the system has automatically intervened, this text message will appear in the instrumentpanel:
•

WARNING
• The "Steering assistance at risk of head- on collision" subfunction is supplemen-tary driver support intended to improvedriving safety – it cannot handle all situa-tions in all traffic, weather and road condi-tions.
• Pilot Assist is only activated if there is ahigh risk of collision – you must thereforenever wait for the function to intervene.
• The function is not a substitute for thedriver's attention and judgment. The driveris always responsible for ensuring thevehicle is driven in a safe manner, at theappropriate speed, with an appropriatedistance to other vehicles, and in accord-ance with current traffic rules and regula-tions.

Limitations of steering assistanceduring collision risks fromoncoming traffic The function may have limited functionality in certain situations and not intervene, e.g.:
•
for smaller vehicles such as motorcycles
• on roads that do not have clear lane mark- ings
• if more than half of your vehicle has movedinto the adjacent lane
• outside the speed range 60-140 km/h(37-87 mph)
• when the power steering works at reducedpower - e.g. during cooling due to overheat-ing (see section "Speed-dependent steeringforce").
Functionality may also be reduced in other situa-tions, such as: • road work
• winter driving conditions
• narrow roads
• poor road surfaces
• a very sporty driving style
• bad weather with reduced visibility.
In these demanding driving conditions, the func-tion may not be able to properly assist the driver.In these situations, it is recommended that it isturned off.
