Steering assistance at risk of collision
The
Collision avoidance assistance function
can help the driver reduce the risk of the vehi- cle leaving its lane unintentionally and/or col-liding with another vehicle or obstacle byactively steering the vehicle back into its laneand/or swerving.
The function consists of these sub-functions: Run-Off Mitigation with steering assis- tance
Steering assistance during collision risksfrom oncoming traffic
Steering assistance during collision risks from behind
*
After the system has automatically intervened, this text message will appear in the instru-ment panel:
Collision avoidance assistance –Automatic intervention
WARNING
The function is supplementary driver support intended to facilitate drivingand help make it safer – it cannot han-dle all situations in all traffic, weatherand road conditions.
The driver is advised to read all sec-tions in the Owner's Manual about thisfunction to learn of its limitations,which the driver must be aware ofbefore using the function.
Driver support functions are not a sub-stitute for the driver's attention andjudgment.

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.

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*
The Park Assist function can help the driver when maneuvering in tight spaces by indicat-ing distances to obstacles using audible sig-nals and graphics in the center display.
Display view showing obstacle zones and sensor sectors.
The center display shows an overview of the vehicle in relation to objects that have beendetected. The marked sector indicates where the obsta- cle is located. The closer the vehicle symbol isto a marked sector forward/rearward, thecloser the detected obstacle is to your vehicle. The side sectors change color as the distance between the vehicle and an object decreases. The audible signals will also speed up the closer the obstacle is to the vehicle. The vol- ume of the audio system will be automaticallylowered. Audible signals for obstacles in front and to the sides of the vehicle are active when thevehicle is moving but will cease after the vehi-cle has been stationary for approx. 2 seconds.Audible signals for obstacles behind the vehi-cle will remain active even when the vehicle isstationary. If a detected obstacle is within approx. 30 cm (1 ft) from the front or rear of the vehicle, thetone will become constant and the active sen-sor's field closest to the vehicle symbol will befilled in. At distances within approx. 25 cm (0.8 ft) from an obstacle to the sides of the vehicle, anrapid pulsing signal will be given and theactive sector fields will change color fromORANGE to RED. The volume of the Park Assist audible signals can be adjusted while the signal is being givenusing the
>II knob or in the center display's
Top view under
Settings.
NOTE
Besides in the sector closest to the vehicle symbol, audible warnings are only providedfor objects located directly in the vehicle'spath.

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)

CAUTION
Objects such as chains, thin and glossy poles or low obstacles may end up in the"signal shadow" and then go temporarilyundetected by the sensors – the pulsatingtone may then unexpectedly stop insteadof becoming a constant tone as expected. The sensors cannot detect high objects, such as protruding ramps. In such situations, pay extra attention and maneuver/drive the vehicle veryslowly or stop the current parkingmaneuver – there may be a high risk ofdamage to the vehicle or other objectssince information from the sensors isnot always reliable in such situations.
CAUTION
In some circumstances, the Park Assist System may produce false warnings due toexternal sound sources with the sameultrasonic frequencies as those the systemworks with. Examples of such sources are horns, wet tires on asphalt, pneumatic brakes, exhaustnoise from motorcycles, etc.
