Park Assist limitations
The Park Assist system has certain limitations.

NOTE
A trailer hitch whose wiring is integrated withthe vehicle's electrical system will be takeninto account when measuring the availablespace behind the vehicle.
NOTE
•The system will not detect high objects,such as a loading dock, etc.
•Certain materials or fabrics may not bedetected by the sensors. Objects made ofthese materials or people wearing cloth-ing made of these fabrics may not bedetected.
•Children or animals near the vehicle maynot always be detected.
•Objects such as chains, thin shiny polesor low objects may temporarily not bedetected by the system. This may resultin the pulsing tone unexpectedly stoppinginstead of changing to a constant tone asthe vehicle approaches the object. Insuch cases, use caution when backing upor stop the vehicle to help avoid damage.
•In certain circumstances, the park assistsystem may give unexpected warning sig-nals that can be caused by externalsound sources that use the same ultra-sound frequencies as the system. Thismay include such things as the horns ofother vehicles, wet tires on asphalt, pneu-matic brakes, motorcycle exhaust pipes,other vehicles with similar ultrasound sys-tems, etc. This does not indicate a fault inthe system.
Cleaning the sensors
Location of the Park Assist sensors
The sensors must be cleaned regularly to ensurethat they work properly. Clean them with waterand a suitable car washing detergent.

NOTE
If the sensors are obstructed by e.g., dirt,snow, or ice, this could result in false warningsignals from the park assist system or thesystem may not function at all.

When the vehicle is backing up, PAP will steer itinto the parking space. Do as follows:
1.Check that the area behind the vehicle isclear and put the gear selector in R.
2. Back up slowly without moving the steeringwheel. The vehicle's speed must be belowapproximately 4 mph (7 km/h).
3. Keep an eye on the instrument panel and beprepared to stop the vehicle when you areinstructed by PAP to do so.

NOTE
•Release the wheel while PAP is steeringthe vehicle.
•The steering wheel must be able to turnfreely.
•For PAP to function optimally, wait untilthe steering wheel is no longer turningbefore beginning the next phase of theparking procedure.
3: Adjusting the vehicle's position
Parallel
Perpendicular
After the vehicle has backed into the parkingspace, its position in the space has to be
adjusted by driving slightly forward and backingup.
1.Put the gear selector in D, wait until thesteering wheel has turned and drive forwardslowly.
2.Stop the vehicle when you are instructed byPAP to do so.
3.Put the gear selector in R, back up slowlyand stop when you are instructed by PAP todo so.
When the parking procedure is finished (this willbe indicated by a text message and a graphicimage), PAP switches off automatically. If neces-sary, the driver may need to make minor adjust-ments to ensure that the vehicle is parked cor-rectly.

CAUTION
The warning distance is shorter when PAP isusing the sensors than when Park Assist isusing them.

Leaving a parking space
This function can only be usedfor a vehicle that has been par-allel parked and is activated inthe center display's Functionview.

•Heavy rain or snow may inhibit PAP'scapacity to correctly measure a parkingspace.
•Do not use PAP when using snow chainsand/or a temporary spare tire.
•Do not use PAP if there are any objects pro-truding from the vehicle.

WARNING
•The front end of your vehicle may turn outtoward oncoming traffic during the park-ing procedure.
•Objects located above the parking sen-sors' field of vision are not included whenPAP measures a parking space. For thisreason, PAP may turn into the parkingspace too soon. Avoid parking spaces ofthis type.
•The driver is always responsible for deter-mining if PAP has selected a suitableparking space.
Maintenance
Location of the PAP sensors
In order for PAP to function correctly, these sen-sors must be cleaned regularly with water and asuitable car washing detergent.
