Perpendicular parking
Procedure for perpendicular parking
PAP helps park the vehicle as follows:
1. The system searches for and measures a
possible parking space. While this is being done, the vehicle's speed may not exceedapprox. 4 mph ( 7 km/h).
2. The vehicle is steered while it is backing into the parking space and its position in thespace is adjusted by prompting the driver to select D or R while the system steers. The
driver has to control the vehicle's speed.
NOTE
PAP's Park out function cannot be used to
help a vehicle leave a parking space if the
Perpendicular parking function was used
to park the vehicle.
WARNING
• PAP does not function in all situations and is only intended to assist the driverduring parallel or perpendicular parking.
• As the driver, you have full responsibilityfor parking the vehicle in a safe manner.

NOTE
If a trailer hitch is configured in the vehicle's electrical system, PAP will take the trailerhitch into consideration when determining thenecessary size of a parking space.
ParkingProcedure for parking:
1. The system searches for and measures apossible parking space.
2. The vehicle is steered while it is backing into the parking space.
3. The vehicle's position is adjusted in the park- ing space by moving forward and rearward.
1: Searching and measuring
Parallel parking
Perpendicular parking
PAP searches for a potential parking space and measures it to see if there is sufficient space foryour vehicle. To start this procedure:
1. Tap the
Park In button in
the center display's Function view. If necessary, slow down to:
• a speed below 20 mph (30 km/h) for parallel parking
• approx. 12 mph ( 20 km/h) for perpendicularparking. 2. Keep an eye on the display and be prepared
to stop the vehicle when you are instructedby PAP to do so.
3. Select
Parallel parking or Perpendicular
parking and put the transmission in reverse.
4. Keep an eye on the display and be prepared to stop the vehicle when you are instructed by PAP to do so.
5. Stop the vehicle when instructed to do so.
NOTE
PAP normally searches for available parking spaces along the curb on the right (passeng-er's) side of the vehicle. However, it can alsoassist in finding and parking in spaces on thedriver's side. To do so:
• Activate the left turn signal. PAP will thensearch for a parking space on the leftside of the vehicle.

capacity weight or maximum permissible axle loads are not exceeded.
• At the specified curb weight your vehicle hasa tendency to understeer, which means thatthe steering wheel has to be turned morethan might seem appropriate for the curva-ture of a bend. This ensures good stabilityand reduces the risk of rear wheel skid.Remember that these properties can alterwith the vehicle load. The heavier the load inthe cargo compartment, the less the ten-dency to understeer.

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 a depth of approximately 9 in. (25 cm) at walkingspeed. Be particularly careful when drivingthrough flowing water. • Take particular care when driving through flowing water.
• 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.
• Avoid driving through salt water if at all pos-sible to help avoid the risk of corrosion.
CAUTION
• Engine damage will occur if water is drawn into the air cleaner.
• Damage to any components, the engine,transmission, turbo-charger, differential orits internal components caused by flood-ing, vapor lock or insufficient oil is notcovered under warranty.
• Do not allow the vehicle to stand in waterup to the door sills longer than absolutelynecessary. This could result in electricalmalfunctions.
• If the engine has been stopped while thevehicle is in water, do not attempt torestart it. Have the vehicle towed out ofthe water.
WARNING
•
Avoid driving through standing or rushing water. Doing so can be dangerous and itmay also be difficult to determine theactual depth of the water.

Driving with a trailer
When towing a trailer, always observe the legal requirements of the state/province.
• All Volvo models are equipped with energy- absorbing shock-mounted bumpers. Trailerhitch installation should not interfere with theproper operation of this bumper system.
Trailer towing does not normally present any par-ticular problems, but take into consideration:
• Increase tire pressure to recommended fullpressure.
• When your vehicle is new, avoid towing heavytrailers during the first 620 miles (1,000 km).
• Maximum speed when towing a trailer:50 mph (80 km/h).
• Engine and transmission are subject toincreased loads. Therefore, engine coolanttemperature should be closely watched whendriving in hot climates or hilly terrain. Use alower gear and turn off the air conditioner ifthe temperature gauge needle enters the redrange.
• If the automatic transmission begins to over-heat, a message will be displayed in the textwindow.
• Avoid overload and other abusive operation.
• Hauling a trailer affects handling, durability,and economy. •
It is necessary to balance trailer brakes withthe towing vehicle brakes to provide a safestop (check and observe state/local regula-tions).
• Do not connect the trailer's brake systemdirectly to the vehicle's brake system.
• More frequent vehicle maintenance isrequired.
• Remove the ball holder when the hitch is notbeing used.
NOTE
•
When parking the vehicle with a trailer on a hill, apply the parking brake before put- ting the gear selector in
P. Always follow
the trailer manufacturer's recommenda- tions for wheel chocking.
• When starting on a hill, put the gear selector in
D before releasing the parking
brake.
• If you use the manual (Geartronic) shift positions while towing a trailer, make surethe gear you select does not put toomuch strain on the engine (using toohigh a gear).
• The drawbar assembly/trailer hitch maybe rated for trailers heavier than the vehi-cle is designed to tow. Please adhere toVolvo's recommended trailer weights.
• Avoid driving with a trailer on inclines ofmore than 15%.

CAUTION
The maximum trailer weights listed are only applicable for altitudes up to 3,280 ft(1000 m) above sea level. With increasingaltitude the engine power and therefore thecar's climbing ability are impaired because ofthe reduced air density, so the maximumtrailer weight has to be reduced accordingly.The weight of the vehicle and trailer must bereduced by 10% for every further 3,280 ft(1,000 m) (or part thereof). When towing5,000 lbs (2,250 kg) hill inclination is restric-ted to 14%.
WARNING
•Bumper-attached trailer hitches must not be used on Volvos, nor should safetychains be attached to the bumper.
• Trailer hitches attaching to the vehiclerear axle must not be used.
• Never connect a trailer's hydraulic brakesystem directly to the vehicle brake sys-tem, nor a trailer's lighting system directlyto the vehicle lighting system. Consultyour nearest authorized Volvo retailer forcorrect installation.
• When towing a trailer, the trailer's safetychains or wire must be correctly fastenedto the attachment points provided in thetrailer hitch on the vehicle. The safetychain or wire must never be fastened toor wound around the towing ball.
