Steering assistance at risk ofcollision
The Collision avoidance assistance functionis intended to help the driver reduce the risk ofthe 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 ofthree sub-functions:
Run-Off Mitigation with steering assistance
Steering assistance during collision risksfrom oncoming traffic
Steering assistance during collision risksfrom 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 howmuch the vehicle should be in control – thevehicle can never take command.

The driver can choose to have this function Onor Off.
Use this button in the centerdisplay's Function view to turnthe function On and Off.
NOTE
When the Collision avoidance assistancefunction is deactivated, all subfunctions of thefollowing are deactivated:
Steering assistance at risk of run-off
Steering assistance at risk of head-oncollision
Steering assistance during collision risksfrom behind*
Although it is possible to deactivate the func-tion, the driver is advised to keep it activatedsince it can help improve driving safety inmost cases.

Run-Off Mitigation with steeringassistance
This sub-function is intended to help reduce therisk of the vehicle inadvertently running off theroad by actively steering the vehicle back ontothe road.
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.

Limitations of Run-Off Mitigationwith steering assistance
In certain demanding driving conditions, thefunction 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'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".

Steering assistance during collisionrisks from oncoming traffic
This sub-function can help assist a distracteddriver who has not noticed that the vehicle isveering into oncoming traffic.
The function provides assistance by swerving your vehi-cle back into your own lane.
Oncoming vehicles
Own vehicle
The function is active at speeds between60-140 km/h (37-87 mph) on roads with clearlyvisible traffic lane markings/lines.
If your vehicle is starting to veer from your ownlane 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 steeringassistance 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.

The function may have limited functionality incertain 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:

Steering assistance during collision
risks from behind*
If you become distracted and do not notice yourvehicle starting to veer out of the lane whileanother vehicle is approaching from behind or isin your vehicle's blind spot, this sub-function canhelp provide assistance.
The function provides assistance by steering your vehi-cle back into your own lane.
Another vehicle in blind spot zone
Own vehicle
If your vehicle is beginning to veer out of yourlane while another vehicle is in your blind spot oranother vehicle is rapidly approaching in the nextlane, this function can help the driver steer thevehicle back into its own lane.
Even if the driver intentionally changes lanesusing a turn signal without noticing another vehi-
cle approaching, the function can provide assis-tance.
The function is active at speeds between60-140 km/h (37-87 mph) on roads with clearlyvisible traffic lane markings/lines.
