CAUTION
Objects such as chains, thin and glossy poles or low obstacles may end up in the "signalshadow" and then go temporarily undetectedby the sensors – the pulsating tone may thenunexpectedly stop instead of becoming aconstant tone as expected. The sensors cannot detect high objects, such as protruding ramps.
• In such situations, pay extra attention andmaneuver/drive the vehicle very slowly orstop the current parking maneuver –there may be a high risk of damage tothe vehicle or other objects since infor-mation from the sensors is not alwaysreliable in such situations.
CAUTION
In some circumstances, the Park Assist Sys- tem may produce false warnings due to exter-nal sound sources with the same ultrasonicfrequencies as those the system works with. Examples of such sources are horns, wet tires on asphalt, pneumatic brakes, exhaust noisefrom motorcycles, etc.
NOTE
When a trailer hitch is configured with the vehicle electrical system, the trailer hitch pro-trusion is included when the function meas-ures the distance to objects behind the vehi-cle.

NOTE
Dirt, ice and snow covering the sensors reduce their function and can make measure-ment impossible.
Driver responsibilityThe driver should keep in mind that PAP is a parking aid ‒ not an infallible fully automatic sys-
tem. The driver must always be prepared to take control and cancel a parking sequence if neces-sary. There are a number of things to keep in mind when parking, including:
• The driver is always responsible for determin-ing if the space suggested by PAP is suita-ble for parking.
• Do not use PAP when using snow chains ora temporary spare tire.
• Do not use PAP if there are any objects pro-truding from the vehicle.
• Heavy rain or snowfall may inhibit PAP's abil-ity to accurately measure a parking space.
• While searching and measuring the parkingspace, PAP may be unable to detect objectslocated far into the space.
• PAP may not suggest parking spaces onnarrow streets if it does not detect sufficientspace for maneuvering the vehicle. •
Use approved tires 124
inflated to the correct
tire pressure because this affects PAP's abil-ity to provide parking assistance.
• PAP's function is based on the way the vehi-cles are parked behind and in front of yourparking 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.
• Perpendicular parking spaces may not bedetected or may be suggested unnecessarilyif a parked vehicle is sticking out more thanother parked vehicles.
• PAP is intended to provide parking assis-tance on straight streets, not sections ofstreet with sharp curves or bends. Alwaysmake sure that your vehicle is parallel to rel-evant parking spaces when PAP is measur-ing the parking space.
CAUTION
Switching to another approved wheel and/or tire dimension could change the tire circum-ference, which would then require the PAPsystem to be updated. Consult a workshop –an authorized Volvo workshop is recom-mended.

STARTING AND DRIVING
426
Slippery driving conditionsFor optimal traction and roadholding, Volvo rec- ommends using snow tires on all wheels when-ever there is a risk of snow or ice on the road.
NOTE
Certain countries require use of winter tires by law. Not all countries permit the use ofstudded tires.
Practice driving on slippery surfaces under con- trolled conditions to learn how the vehicle reacts.

Driving through standing water
Driving the vehicle through a deep pool of stand- ing water on a water-covered roadway is calledfording. This must be done with great caution.
The vehicle can be driven through water up to a depth of 25 cm (9.8 in) at no more than walkingspeed. Be particularly careful when drivingthrough flowing water. When driving through standing water, drive slowly and do not stop the vehicle. When you havepassed the water, press lightly on the brake pedaland check that the brakes are functioning prop-erly. Water, mud, slush, etc. can make the brakelinings slippery, resulting in delayed brakingeffect.
• If the vehicle is equipped with contacts for anelectric heater or trailer coupling, clean theseafter driving in water or mud.
• Do not allow the vehicle to stand in water upto the sills any longer than absolutely neces-sary. This could result in electrical malfunc-tions.
CAUTION
• Engine damage could occur if water enters the air cleaner.
• If water enters the transmission, the lubri-cating ability of the oils is reduced andthe service life of these systems is short-ened.
• Damage to any component, engine,transmission, turbocharger, differential orits internal components caused by flood-ing, vapor lock or insufficient oil is notcovered under warranty.
• If the engine stalls while the vehicle is inwater, do not attempt to restart it. Havethe vehicle towed out of the water to aworkshop. An authorized Volvo workshopis recommended. Risk of engine failure.

WARNING
•The vehicle must never be driven with more than one "Temporary spare" tiremounted.
• Driving with a spare wheel may alter thedriving characteristics of the vehicle.Replace the spare wheel with a normalwheel as soon as possible.
• The spare wheel is smaller than the nor-mal wheel, which affects the vehicle'sground clearance. Watch for high curbsand do not wash the vehicle in an auto-matic car wash when a spare wheel ismounted.
• Follow the manufacturer's recommendedtire inflation pressure for the spare wheel.
• On all-wheel drive vehicles, the drive onthe rear axle can be disconnected.
• If the spare wheel is mounted on thefront axle, snow chains must not be used.
• The spare wheel must not be repaired.
CAUTION
The vehicle must not be driven with wheels of different dimensions or with a spare tire otherthan the one that came with the vehicle. Theuse of different size wheels can seriouslydamage your vehicle's transmission.
This illustration is general. The shape and design of the foam block may vary depending on vehicle model.
The spare wheel is located in the spare wheel well with the outside of the wheel facing down-ward. The same bolt runs through both the sparewheel and foam block to hold them into place.The foam block contains all tools needed tochange a wheel.

Snow tires
Snow tires are designed for winter driving.
Volvo recommends snow tires with specific dimensions. The tire dimensions vary dependingon engine type. When driving with snow tires, thecorrect type of tires must be mounted on all fourwheels.
NOTE
Contact a Volvo dealer for advice on the best choice of rims and tires.
Tips for changing snow tiresWhen switching between regular tires and snow tires, mark the tires according to which side they were mounted on, e.g. L for left and R for right.
Studded tiresStudded tires should be broken in by driving 500–1000 km (300–600 miles) slowly and gen-tly to help the studs settle properly in the tires.This gives the tire, and especially the studs, alonger service life.
NOTE
Regulations regarding the use of studded tires vary from country to country.
Tread depthRoad conditions with ice, slush and low tempera- tures place considerably higher demands on tiresthan summer conditions. Volvo therefore recom-mends not driving on snow tires that have a treaddepth of less than 4 mm (0.15 inch).

Snow chains
Using snow chains and/or snow tires can help improve traction in winter driving conditions.
WARNING
Use Volvo genuine snow chains or equivalent snow chains that are suitable for the vehicle model and the tire and wheel sizes. Only one-
sided snow chains are permitted.
If uncertain about snow chains, Volvo recom- mends contacting an authorized Volvo work-shop. Use of the wrong snow chains couldcause serious damage to the vehicle andresult in an accident.

CAUTION
Snow chains can be used on the vehicle, with the following restrictions:• Volvo recommends not using snowchains on wheel dimensions larger than18 inches.
• Always follow the manufacturer's installa-tion instructions carefully. Install chainsas tightly as possible and retighten peri-odically.
• Only put snow chains on the front wheels(also applies to all-wheel drive vehicles).
• If accessory, aftermarket or "custom"tires and wheels with different dimen-sions than the original tires and wheelsare used, snow chains in some casesmay NOT be used. Sufficient distancebetween the chains and brakes, suspen-sion and body components must bemaintained.
• Check local regulations regarding the useof snow chains before installing.
• Never exceed the snow chain manufac-turer's specified maximum speed limit.Under no circumstances should youexceed 50 km/h (30 mph).
• Avoid bumps, holes or sharp turns whendriving with snow chains.
• Avoid driving on surfaces without snow as this wears out both the snow chains andthe tires.
• The handling of the vehicle can beadversely affected when driving withchains. Avoid fast or sharp turns as wellas locked wheel braking.
• Some types of strap-on chains affectbrake components and therefore mustNOT be used.
Consult a Volvo retailer for more information about snow chains.

Tire sealing system12
The temporary tire sealing system can be used to seal a puncture in a tire or to check andadjust the pressure in the tire. Models equipped with a spare wheel 13
do not
have the tire sealing system.
The tire sealing system consists of a compressor and a bottle containing sealing compound. Thesealing functions as a temporary repair.
NOTE
The sealing compound effectively seals tires with punctures in the tread but may not beable to fully seal tires with punctures in thesidewall. Do not use the tire sealing systemon tires with large tears, cracks or similardamage.
NOTE
The compressor is intended for temporary tire sealing and is approved by Volvo.
LocationThe tire sealing system is located in a foam block under the floor of the trunk.
