Run-Off Mitigation with steering assistance
Steering assistance has several sub-func- tions. Run-Off Mitigation with steering assis-tance can help the driver and reduce the riskof the vehicle inadvertently running off theroad by actively steering the vehicle backonto the road.
This function has two activation levels for intervention: Steering assistance only
Steering assistance with braking
Steering assistance only
Intervention with steering assistance.

Steering assistance with braking
Intervention with steering assistance and braking.
Braking intervention assists in situations where steering assistance alone is not suffi-cient. Braking force is automatically adaptedaccording to the situation at the moment thevehicle begins to run off the road. The function is active at speeds between 65-140 km/h (40-87 mph) on roads withclearly visible traffic lane markings/lines. The system uses a camera to monitor the edges of the road and the painted side markerlines. If the vehicle is about to cross the edgeof the road, the function will attempt to steerthe vehicle back onto the road. If this is notsufficient to keep the vehicle on the road, thebrakes 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 operatingthe vehicle.

354 The function is active at speeds between
60-140 km/h (37-87 mph) on roads with clearly visible traffic lane markings/lines. If your vehicle is starting to veer from your own lane and a vehicle is approaching fromthe opposite direction, this function can helpthe driver steer the vehicle back into its ownlane. However, the function will not provide steer-
ing assistance if the turn signal is used. The function will also not be activated if it detectsthat the driver is actively operating the vehicle.

Steering assistance during collision risks from behind
*
Steering assistance has several sub-func- tions. If you become distracted and do notnotice your vehicle starting to veer out of thelane while another vehicle is approachingfrom behind or is in your vehicle's blind spot,Steering assistance during collision risksfrom behind can help provide assistance.
The function provides assistance by steering your vehicle back into your own lane.
Another vehicle in blind spot zone
Own vehicle
If your vehicle is beginning to veer out of your lane while another vehicle is in your blind spotor another vehicle is rapidly approaching in the next lane, this function can help the driversteer the vehicle back into its own lane. Even if the driver intentionally changes lanes using a turn signal without noticing anothervehicle approaching, the function can provideassistance. The function is active at speeds between 60-140 km/h (37-87 mph) on roads withclearly visible traffic lane markings/lines. The lights in the door mirrors will flash while steering assistance is being provided, whether or not the BLIS

Steering assistance during collision risks limitations
The function may have limited functionality in certain situations and not intervene, e.g.:
for smaller vehicles such as motorcycles
if more than half of your vehicle has moved into the adjacent lane
on roads/lanes with indistinct or no sidelane markings
outside the speed range 60-140 km/h(37-87 mph)
when speed-dependent power steeringwheel resistance is working at reducedpower – e.g. during cooling due to over-heating.
Functionality may also be reduced in other sit-uations, 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 function may not be able to properly assist thedriver. In these situations, it is recommendedthat it is turned off.
NOTE
The function uses the vehicle's camera and radar sensor, which has certain generallimitations.

Park Assist front, rear and sides *
Park Assist behaves differently depending on which part of the vehicle is approaching anobstacle.
Front camera
The warning signal has a continuous tone when the obstacle is less than approx. 30 cm (1 ft) from thevehicle.
The Park Assist system's front sensors are automatically activated when the engine isstarted. They are active at speedsbelow 10 km/h (6 mph). The distance monitored extends approx. 80 cm (2.5 ft) in front of the vehicle.
NOTE
The Park Assist system is deactivated when the parking brake is used or when P
is selected on vehicles with automatictransmission.
CAUTION
When installing auxiliary lights: Make sure these do not obscure the sensors – theauxiliary lights could be perceived as anobstacle.
Back
The warning signal has a continuous tone when the obstacle is less than approx. 30 cm (1 ft) from thevehicle.
The rear sensors will be activated if the vehicle begins rolling backward or if reverse gear isengaged. The distance monitored extends approx. 1.5 meters (5 ft) behind the vehicle.
Side sensors
The warning signal will begin pulsating rapidly when the obstacle is less than approx. 25 cm (0.8 ft) fromthe vehicle.
Park Assist's side sensors are automatically activated when the engine is started. They areactive at speeds below 10 km/h (6 mph). The distance monitored is approx. 25 cm (0.8 ft) out from the sides. The detection area of the side sensors increa- ses significantly, however, when the steering angle of the front wheel increases and depending on the position of the steeringwheel, obstacles up to approx. 90 cm (3 ft)

Park Assist Camera trajectory lines
*
The Park Assist Cameras use trajectory lines and fields on the screen to indicate the vehi-cle's position in relation to its immediate sur-roundings.
Example of trajectory lines.
The lines on the screen are projected as if they were painted lines on the ground behind thevehicle and are directly affected by the way inwhich the steering wheel is turned. This makes it possible for the driver to see path thevehicle will take, even if he/she turns thesteering wheel.
CAUTION

Bear in mind that when the rearward camera view is selected, the screenonly shows the area behind the vehicle– pay attention to the sides and frontof the vehicle when steering whilereversing.
The same applies to the reverse – payattention to what is happening withthe rear parts of the vehicle when thefront camera view is selected.
Note that the guide lines show theshortest
path – pay extra attention to
ensure that the vehicle sides do notcome in contact with/travel over any-thing when steering while driving for-ward or that the vehicle front movestoward/over anything when steeringwhile reversing.

When the sensor field color is red, the audible pulsing sounds will change to a continuoustone.
Side sensor fields
Warning signals vary depending on the vehi- cle's intended direction of travel. Dependingon the steering wheel position, warnings maybe given for obstacles diagonally in front of orbehind the vehicle, not only directly behind thevehicle.
Parking sensor sectors where obstacles can be detected.
Left-side front sensor field
Obstacle sector in the vehicle's intended direction of travel forward – varies accord-ing to steering wheel position
Sector with RED field color and rapidly pulsing tone
Right-side rear sensor field
Obstacle sector in the vehicle's intended direction of travel rearward – variesaccording to steering wheel position.
