Checking tire pressure
Correct inflation pressure helps improve driv- ing stability, save fuel and increase the serv-ice life of the tires.
Tire pressure decreases over time, which is normal. Tire pressure also varies depending onthe ambient temperature. Driving on under-inflated tires could cause the vehicle to over-heat and lead to damage. Tire pressure affectstraveling comfort, road noise and driving cha-racteristics. Check the pressure in the tires every month. Use the recommended inflation pressure forcold tires to help maintain good tire perform-ance. Under-inflated or over-inflated tirescould cause uneven tread wear. Use an air pressure gauge and check the infla- tion pressure on all the tires, including the spare tire 4
, at least once a month and before
long trips. Volvo recommends buying a relia- ble air pressure gauge, as the automaticgauges provided at service stations may beinaccurate.
WARNING
Under-inflation is the most common cause of tire failure and may result insevere tire cracking, tread separation,or "blow-out," with unexpected loss ofvehicle control and increased risk ofinjury.
Under-inflated tires reduce the loadcarrying capacity of your vehicle.
Cold tiresInflation pressure should be checked when thetires are cold. The tires are considered to becold when they have the same temperature asthe surrounding (ambient) air. This tempera-ture is normally reached after the vehicle hasbeen parked for at least 3 hours. After driving for approximately 1.6 km (1 mile), the tires are considered to be warm. If youneed to drive longer than that to inflate thetires, check and record the inflation pressureof the tires first and inflate accordingly whenyou arrive at the pump. When the ambient temperature changes, so does the inflation pressure. A 10-degree tem-perature drop causes a corresponding drop ininflation pressure of 1 psi (7 kPa). Check theinflation pressure of the tires regularly andadjust to the correct pressure, which can be found on the vehicle's tire information decal orcertification label. If you check inflation pressure when the tires are warm, you should never release air. Thetires become warm after driving and it is nor-mal for warm tires to have an inflation pres-sure above the recommended pressure forcold tires. A warm tire with an inflation pres-sure equal to or under the recommended pres-sure for cold tires could be significantly under-inflated.Related information

Adjusting tire pressureTire pressure decreases over time, which is normal. The tire pressure must therefore beadjusted to maintain the recommended tirepressure.
Use the recommended inflation pressure for cold tires to help maintain good tire perform-ance and even wear.
NOTE
To help prevent incorrect inflation pressure, pressure should be checked when the tiresare cold. The tires are considered to becold when they have reached the sametemperature as the ambient temperature(about 3 hours after the vehicle was lastdriven). After driving for a few kilometers,the tires will warm up and the pressure willincrease.
1. Remove the valve cap from the tire and press the air pressure gauge firmly onto the valve.
2. Inflate the tire to the correct inflation pres- sure; see the tire pressure placard on thedriver's side B pillar for recommendedpressures for factory-mounted tires. 3. Screw the valve cap back on.
NOTE

After inflating a tire, always replace the valve cap to help prevent valve damagecaused by gravel, dirt, etc.
Use plastic valve caps only. Metal capscould corrode and become difficult toremove.
4. Visually inspect the tire to make sure there
are no nails or other embedded objects that could puncture the tire and cause airleakage.
5. Check the sidewalls to make sure there are no gouges, cuts, bulges or other irreg-ularities.
6. Repeat this procedure for each tire, includ- ing the spare tire 5
.
NOTE
If you have overfilled the tire, release air by pushing on the metal stem in the center ofthe valve. Then recheck the pressure withyour tire gauge. Some spare tires require higher inflation pressure than the other tires. Consult thetire inflation pressure table or the inflationpressure decal.

General information about the tire pressure monitoring system
In the following description, the tire monitor- ing system is generally referred to as TPMS. Each tire, including the spare (if provided)7
should be checked monthly when cold and inflated to the inflation pressure recom-mended by the vehicle manufacturer on thevehicle placard or tire inflation pressure label.(If your vehicle has tires of a different size thanthe size indicated on the vehicle placard or tireinflation pressure label, you should determinethe proper tire inflation pressure for thosetires.) As an added safety feature, your vehicle has been equipped with a tire pressure monitoringsystem (TPMS) that illuminates a low tirepressure telltale when one or more of yourtires is significantly under-inflated. Accord-ingly, when the low tire pressure telltale illumi-nates, you should stop and check your tires assoon as possible, and inflate them to theproper pressure. Driving on a significantly under-inflated tire causes the tire to overheat and can lead to tirefailure. Under-inflation also reduces fuel effi-ciency and tire tread life, and may affect thevehicle's handling and stopping ability. Please note that the TPMS is not a substitute forproper tire maintenance, and it is the driver'sresponsibility to maintain correct tire pressure,even if under-inflation has not reached thelevel to trigger illumination of the TPMS lowtire pressure telltale. Your vehicle has also been equipped with a TPMS malfunction indicator to indicate whenthe system is not operating properly. TheTPMS malfunction indicator is combined withthe low tire pressure telltale. When the systemdetects a malfunction, the telltale will flash forapproximately one minute and then remaincontinuously illuminated. This sequence willcontinue upon subsequent vehicle start-ups aslong as the malfunction exists. When the mal-function indicator is illuminated, the systemmay not be able to detect or signal low tirepressure as intended. TPMS malfunctions may occur for a variety of reasons, including the installation of replace-ment or alternate tires or wheels on the vehi-cle that prevent the TPMS from functioningproperly. Always check the TPMS malfunction telltale after replacing one or more tires or wheels onyour vehicle to ensure that the replacement oralternate tires and wheels allow the TPMS tocontinue to function properly.
To keep in mind

Always save the new inflation pressure inthe system after changing a tire or adjust-ing the inflation pressure.
If you switch to a tire of another size thanthe factory-mounted tires, the systemmust be reset by storing a new inflationpressure for these tires to avoid falsewarnings.
If a spare wheel 8
is used, it is possible that
the tire pressure monitoring system willnot work correctly due to the differencesbetween the wheels.
The system does not replace the need forregular tire inspection and maintenance.
It is not possible to deactivate the tirepressure monitoring system.
WARNING

Incorrect inflation pressure could lead to tire failure, which could cause thedriver to lose control of the vehicle.
The system cannot predict sudden tiredamage.

Spare wheel 14
The spare wheel is a Temporary Spare and can be used to temporarily replace a punc-tured tire on one of the vehicle's regularwheels.
The spare wheel is only intended for tempo- rary use. Replace it with a normal wheel assoon as possible. The driving characteristics of the vehicle change and ground clearance reduces whenthe spare wheel is used. Do not wash the vehi-cle in an automatic car wash while using theTemporary Spare. The recommended tire pressure must be maintained regardless of at which position thetemporary spare wheel is used on the vehicle. If the spare wheel is damaged, a replacement can be purchased from a Volvo retailer.
WARNING
Current legislation prohibits the use of the "Temporary Spare" wheel other than as atemporary replacement for a puncturedtire. It must be replaced as soon as possi-ble by a standard tire. Roadholding andhandling may be affected with the "Tempo-rary Spare" wheel in use.
WARNING
Never drive faster than 80 km/h (50 mph) with a spare tire mounted onthe vehicle.
The vehicle must never be driven withmore than one "Temporary Spare"wheel mounted.
Driving with a spare wheel may alterthe driving characteristics of the vehi-cle. Replace the spare wheel with anormal wheel as soon as possible.
The spare wheel is smaller than thenormal wheel, which affects the vehi-cle's ground clearance. Watch for highcurbs and do not wash the vehicle inan automatic car wash when a sparewheel is mounted.
Follow the manufacturer's recom-mended tire inflation pressure for thespare wheel.
On all-wheel drive vehicles, the driveon the rear axle can be disconnected.
If the spare wheel is mounted on thefront axle, snow chains must not beused.
The spare wheel must not be repaired.
