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.

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 the vehicle
• 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 display indicate when the various steps in the parkingprocedure will be carried out. PAP can be activated if the following conditions are 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)

DRIVER SUPPORT
* Option/accessory.343
Points to keep in mindPAP is a parking aid only and the driver should always be prepared to take control and cancel aparking sequence. This can be due to one ormore of the following factors:
• PAP's function is based on the way that thevehicles are parked behind and in front ofyour parking space. If they are, for example,parked too close to the curb, there is a riskthat your vehicle's tires or wheel rims couldbe damaged by the curb during the parkingprocedure.
• PAP is intended to provide parking assis-tance on straight streets, not sections ofstreet with curved or irregular curbs. Be surethat your vehicle is parallel to the curb whenPAP measures the parking space.
• PAP may not be able to provide parkingassistance on narrow streets due to lack ofspace to maneuver the vehicle. In situationslike this, it may help to drive between1.5-5.0 ft (0.5-1.5 m) from the side of theroad where the parking space is located.
• Use only approved tires with the correct infla-tion pressure because this affects PAP'scapacity to provide parking assistance.Changing to a different approved tire sizemay affect PAP's parameters. Consult atrained and qualified Volvo service technician. •
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 out toward 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.

Starting and driving The vehicle is equipped with features that sup- plement its basic functions, such as shifting gears with steering wheel paddles * and the fuel-
conserving start/stop function.
The vehicle is equipped with an automatic trans- mission that also makes it possible to shift gearsmanually. Certain functions can also be used when the engine is not running, depending on the ignitionmode being used.

Brakes The brake system is a hydraulic system consist- ing of two separate brake circuits. If a problemshould occur in one of these circuits, it is stillpossible to stop the vehicle with the other brakecircuit.
Brake systemIf one of the brake circuits is not functioning, more pressure will be needed on the brake pedal(and the pedal will go down farther) for normalbraking effect. If the brake pedal must be depressed farther than normal and requires greater foot pressure,the stopping distance will be longer. Pressure on the brake pedal is enhanced by the power braking function. The power brakes only function when the engine is running. If the power brakes are not working, considerably higher pressure will be required on the brakepedal to compensate for the lack of power assis-tance. This can happen for example when towingyour vehicle or if the engine is switched off whenthe vehicle is rolling. The brake pedal feels stifferthan usual. When the Hill Start Assist function is being used, it will take slightly longer for the brake pedal toreturn to its normal position if the vehicle isparked on an incline or uneven surface. When driving in very hilly areas or if the vehicle iscarrying a heavy load, manual gear shifting canbe used for engine braking to augment the brakes.
Hill Descent Control can also be used
on steep downgrades to increase the engine braking effect at low speeds.
Anti-lock Braking System ABS
The ABS system helps to improve vehicle control (stopping and steering) during severe brakingconditions by limiting brake lockup. When ABS is operating, there may be some vibration in the brake pedal, which is normal. The system performs a brief self-diagnostic test when the engine has been started and driverreleases the brake pedal. Another automatic testmay be performed when the vehicle first reachesa speed of approximately 6 mph (10 km/h). Thebrake pedal will pulsate several times and asound may be audible from the ABS controlmodule, which is normal.
Cleaning the brake discsCoatings of dirt and water on the brake discsmay result in delayed brake function. This delay isminimized by cleaning the brake linings. Cleaning the brake pads is advisable in wet weather, prior to long-term parking, and after thevehicle has been washed. Do this by braking gen-tly for a short period while the vehicle is moving.

Brake functions
The vehicle's standard braking features are aug- mented by a number of auxiliary help functions.
In addition to the wheel brakes and the parking brake, the vehicle is equipped with several auto-matic brake assist functions. These systems helpthe driver by e.g., keeping the vehicle stationarywhen the brake pedal is not depressed (at a traf-fic light or intersection), when starting up a hill orwhen driving down a hill. These systems include: • Auto-hold brakes
• Hill Start Assist
• Braking assist after a collision

Auto-hold brake function
With the Auto-hold brake function, the driver can release the brake pedal and the brakes willremain applied, for example, when the vehiclehas stopped at a traffic light or intersection.
When the vehicle is no longer moving forward, Auto-hold applies the brakes automatically, eitherusing the normal brakes or the parking brake.The brakes will be released when the acceleratorpedal is depressed. If the driver's door is opened or the engine is turned off, the parking brake will be applied auto-matically. Auto-hold is deactivated when the transmission is in neutral or if the driver's door is open and theseat belt is unbuckled.

Before a long distance trip
It is always worthwhile to have your vehicle checked by a trained and qualified Volvo servicetechnician before driving long distances. Yourretailer will also be able to supply you with bulbs,fuses, spark plugs and wiper blades for your usein the event that problems occur.
As a minimum, the following items should be checked before any long trip:
• Check that engine runs smoothly and thatfuel consumption and the oil level are normal.
• Check for fuel, oil, and fluid leakage.
• Check condition of drive belts.
• Check state of the battery's charge.
• Examine tires carefully (including the sparetire where applicable), and replace those thatare worn. Also, check tire inflation pressure.
• The brakes, front wheel alignment, and steer-ing gear should be checked by a trained andqualified Volvo service technician only.
• Check all lights, including high beams.
• Reflective warning triangles are legallyrequired in some states/provinces.
• Have a word with a trained and qualifiedVolvo service technician if you intend to drive

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.
• 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.

Winter driving
Check your vehicle before the approach of cold weather.
The following advice is worth noting:
• Make sure that the engine coolant contains 50 percent antifreeze. Any other mixture willreduce freeze protection. This gives protec-tion against freezing down to –31 °F(–35 °C). The use of "recycled" antifreeze isnot approved by Volvo. Different types ofantifreeze must not be mixed.
• Volvo recommends using only genuine Volvoantifreeze in your vehicle's radiator.
• Try to keep the fuel tank well filled – thishelps prevent the formation of condensationin the tank. In addition, in extremely coldweather conditions it is worthwhile to addfuel line de-icer before refueling.
• The viscosity of the engine oil is important.Oil with low viscosity (thinner oil) improvescold-weather starting as well as decreasingfuel consumption while the engine is warm-ing up. Full synthetic 0W-30 oil is recom-mended for driving in areas with sustainedlow temperatures.
• The load placed on the battery is greater dur-ing the winter since the windshield wipers,lighting, etc., are used more often. Moreover,the capacity of the battery decreases as thetemperature drops. In very cold weather, apoorly charged battery can freeze and be damaged. It is therefore advisable to checkthe state of charge more frequently andspray an anti-rust oil on the battery posts.
• Volvo recommends the use of snow tires onall four wheels for winter driving.
• To prevent the washer fluid reservoir fromfreezing, add washer solvents containingantifreeze. This is important since dirt is oftensplashed on the windshield during winterdriving, requiring the frequent use of thewashers and wipers. Volvo Washer Solventshould be diluted as follows: Down to 14 °F(–10 °C): 1 part washer solvent and 4 partswater Down to 5 °F (–15 °C): 1 part washersolvent and 3 parts water Down to 0 °F(–18 °C): 1 part washer solvent and 2 partswater Down to –18 °F (–28 °C): 1 partwasher solvent and 1 part water.
• Use Volvo Teflon Lock Spray in the locks.
• Avoid using de-icing sprays as they cancause damage to the locks.

Towing eyelet
When used, the towing eyelet should always be securely attached in the openings on the rightside of the front and rear bumpers. There arecovers over these attachment points.
Using the towing eyelet
Take out the towing eyelet, which is stored under the floor in the trunk.
