Adjusting tire pressureTire pressure decreases over time, which is nor- mal. The tire pressure must therefore beadjusted to maintain the recommended tire pres-sure.
Use the recommended inflation pressure for cold tires for optimal tire performance and wear.
NOTE
To help prevent incorrect inflation pressure, pressure should be checked when the tiresare cold. The tires are considered to be coldwhen they have reached the same tempera-ture as the ambient temperature (about 3hours after the vehicle was last driven). Afterdriving for a few kilometers, the tires will warmup and the pressure will increase.
1. Remove the valve cap from the tire and press the air pressure gauge firmly onto the valve.
2. Inflate to the recommended inflation pres- sure. 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 air leak-age.
5. Check the sidewalls to make sure there are no gouges, cuts, bulges or other irregulari-ties.
6. Repeat this procedure for each tire, including 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 pres- sure than the other tires. Consult the tireinflation pressure table or the inflation pres-sure placard.

Recommended tire pressure
The tire pressure placard on the driver's side B pillar (between the front and the rear door) indi-cates tire pressure for different loads and speedconditions.
The placard specifies the designation for the fac- tory-mounted tires on the vehicle, as well as loadlimits and inflation pressures.

Tire pressure monitoring system
*
The tire pressure monitoring system, Tyre Pressure Monitoring System (TPMS), provides awarning symbol in the instrument panel if pres-sure is too low in one or more tires.
SymbolExplanation
This symbol illuminates to indicate low inflation pressure. If there is a system malfunction, the inflation pressure warning symbolwill flash for approximately oneminute and then glow steadily.
System descriptionThe tire pressure monitoring system measures differences in rotational speed between thewheels through the ABS system to determine ifthe tires are properly inflated. If inflation pressure in a tire is too low, its diameter (and consequently its rotational speed) changes. By comparing thetires with each other, the system can determine ifthe pressure in one or more tires is too low.
General information about the tire pressure
monitoring system
In the following description, the tire monitoring system is generally referred to as TPMS. Each tire, including the spare tire (if provided) 6
,
should be checked monthly when cold and infla- ted to the inflation pressure recommended by the vehicle manufacturer on the vehicle placard ortire inflation pressure label. (If your vehicle hastires of a different size than the size indicated onthe vehicle placard or tire inflation pressure label,you should determine the proper tire inflationpressure for those tires.) As an added safety feature, your vehicle has been equipped with a tire pressure monitoringsystem (TPMS) that illuminates a low tire pres-sure telltale when one or more of your tires issignificantly under-inflated. Accordingly, when thelow tire pressure telltale illuminates, you shouldstop and check your tires as soon as possible,and inflate them to the proper pressure. Driving on a significantly under-inflated tire cau- ses the tire to overheat and can lead to tire fail-ure. Under-inflation also reduces fuel efficiencyand tire tread life, and may affect the vehicle'shandling and stopping ability. Please note thatthe TPMS is not a substitute for proper tire main-tenance, and it is the driver's responsibility tomaintain correct tire pressure, even if under-infla-tion has not reached the level to trigger illumina-tion of the TPMS low tire pressure telltale. Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when thesystem is not operating properly. The TPMS mal-function indicator is combined with the low tirepressure telltale. When the system detects a mal-

538 function, the telltale will flash for approximately one minute and then remain continuously illumi-nated. This sequence will continue upon subse-quent vehicle start-ups as long as the malfunc-tion exists. When the malfunction indicator is illu-minated, the system may not be able to detect orsignal low tire pressure as intended. TPMS malfunctions may occur for a variety of reasons, including the installation of replacementor alternate tires or wheels on the vehicle thatprevent the TPMS from functioning properly. Always check the TPMS malfunction telltale after replacing one or more tires or wheels on yourvehicle to ensure that the replacement or alter-nate tires and wheels allow the TPMS to con-tinue to function properly.
Messages in the instrument panelIf tire pressure is too low, the low tire pressurewarning symbol is shown in the instrument panelalong with a message.

NOTE
Always remember to calibrate the Tire Pres- sure Monitoring System when the wheelshave been changed or the tire inflation pres-sure has been corrected according to the tirepressure decal or tire inflation pressure table. If correct reference values have not been set, the system cannot issue low tire pressurealerts correctly. The vehicle must be stationary with the engine running to access the calibration but-ton and to start the calibration process.
WARNING
The exhaust gases contain carbon monoxide, which is invisible and odorless but very poi-sonous. For this reason, always perform thecalibration procedure outdoors or in a work-shop with exhaust gas evacuation equipment.

Spare wheel11
The spare wheel is a Temporary spare and can be used to temporarily replace a punctured tireon one of the vehicle's regular wheels.
The spare tire is only intended for temporary use. Replace it with a normal wheel as soon as possi-ble. The driving characteristics of the vehicle change and ground clearance reduces when the sparewheel is used. Do not wash the vehicle in anautomatic car wash while using the TemporarySpare. The recommended tire pressure must be main- tained regardless of at which position the tempo-rary spare wheel is used on the vehicle. If the spare wheel is damaged, a new one can be purchased from a Volvo retailer.
WARNING
Current legislation prohibits the use of the "Temporary Spare" tire other than as a tem-porary replacement for a punctured tire. Itmust be replaced as soon as possible by astandard tire. Road holding and handling maybe affected with the "Temporary Spare" inuse. Do not drive faster than 80 km/h(50 mph).

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.
