Using Park Assist Pilot (PAP)*
Park Assist Pilot (PAP) gives the driver instruc-tions during the parking procedure. The functioncan also assist when leaving a parking space.
NOTE
While PAP is active, the driver's task is to:
•carefully monitor the area around thevehicle
•follow the instructions provided in thecenter display
•select a gear (D or R) when prompted
•regulate the vehicle's speed
•apply the brakes when necessary andstop the vehicle
Symbols, images and text in the center displayindicate when the various steps in the parkingprocedure will be carried out.
PAP can be activated if the following conditionsare met after the engine has started:
•The vehicle may not be towing a trailer.
•The vehicle's speed must be below approx.20 mph (30 km/h).
•The distance between the vehicle and aparking space must be between 1.6-5.0 ft(0.5-1.5 m)
NOTE
If a trailer hitch is configured in the vehicle'selectrical system, PAP will take the trailerhitch into consideration when determining thenecessary size of a parking space.

Parking
Procedure for parking:
1. The system searches for and measures apossible parking space.
2. The vehicle is steered while it is backing intothe parking space.
3. The vehicle's position is adjusted in the park-ing space by moving forward and rearward.

DRIVER SUPPORT
* Option/accessory, for more information, see Introduction.373
•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.

Driving through standing water
The vehicle should be driven with extreme cau-tion if it is necessary to drive through standingwater.
The vehicle can be driven through water up to adepth approximately level with the floor at walk-ing speed to help prevent water from enteringthe differential and/or the transmission or dam-aging electrical components.
•If possible, check the depth of the waterbefore driving through it. Take particular carewhen driving through flowing water.
•Before driving through water, always selectthe Off Road drive mode to ensure that thegasoline engine is running and to maximizeground clearance.
•After driving through water, apply the brakesand check that they are functioning correctly.
•Clean the electrical connections for trailerwiring after driving in mud or water.
•When driving through water, maintain lowspeed and do not stop in the water.

CAUTION
•Damage may occur to the engine, trans-mission, electrical components, etc. if thevehicle is driven through water higherthan its floor level. Be aware that wavescreated by other vehicles could cause thelevel to temporarily be above the vehicle'sfloor level.
•Damage to any components due to waterabove the floor level, vapor lock or insuffi-cient oil is not covered under warranty.
•If the engine has been stopped while thevehicle is in water, do not attempt torestart it. Have the vehicle towed out ofthe water and inspected by a trained andqualified Volvo service technician.

WARNING
•Avoid driving through standing or rushingwater. Doing so can be dangerous and itmay also be difficult to determine theactual depth of the water.
•If water cannot be avoided, after drivingthrough the water, press lightly on thebrake pedal to ensure that the brakes arefunctioning normally. Water or mud canmake the brake linings slippery, resultingin delayed braking effect.

Overheating the engine andtransmission
In demanding driving conditions, such as whentransporting heavy loads, driving in mountainousareas or in very hot weather there is a risk ofoverheating the engine or transmission.
•The engine's output may be slightly limited ifthere is a risk of overheating.
•Remove e.g., auxiliary lights mounted in frontof the grille in hot weather.
•If the temperature of the engine coolantbecomes too high, the warning symbol willilluminate and the message Enginetemperature/Stop safely will be displayed.Stop the vehicle as soon as possible in asafe place and let the engine idle for severalminutes.
