Tire economy
•
Maintain correct tire pressure.
• Avoid fast starts, hard braking and tirescreeching.
• Tire wear increases with speed.
• Correct front wheel alignment is very impor-tant.
• Unbalanced wheels impair tire economy anddriving comfort.
• Tires must maintain the same direction ofrotation throughout their lifetime.
• When replacing tires, the tires with the mosttread should be mounted on the rear wheelsto reduce the chance of oversteer duringhard braking.
• Hitting curbs or potholes can damage thetires and/or wheels permanently.
Tire rotationYour vehicle has no required tire rotation. Tirewear is affected by a number of factors such astire inflation, ambient temperature, driving style,etc.
NOTE
•If the tires are rotated, they should only be moved from front to rear or vice versa.They should never be rotated left toright/right to left.
• Ideally, tire rotation should be done thefirst time after approximately 3,000 miles(5,000 km) and thereafter at 6,000-mile(10,000-km) intervals. Some customersfind that tire rotation may help to getextra mileage from tire life.
• Tire rotation should only be performed iffront/rear tire wear is fairly even andtread height is above 1/16" (1.6 mm).
Storing wheels and tiresWhen storing complete wheels (tires mounted on rims), they should be suspended off the floor orplaced on their sides on the floor. Tires not mounted on rims should be stored on their sides or standing upright, but should not besuspended.
CAUTION
Tires should preferably be stored in a cool, dry, dark place, and should never be stored inclose proximity to solvents, gasoline, oils, etc.
WARNING
• The wheel and tire sizes for your Volvo are specified to meet stringent stabilityand handling requirements. Unapprovedwheel/tire size combinations can nega-tively affect your vehicle's stability andhandling.
• Any damage caused by installation ofunapproved wheel/tire size combinationswill not be covered by your new vehiclewarranty. Volvo assumes no responsibilityfor death, injury, or expenses that mayresult from such installations.

Uniform Tire Quality Grading
ALL PASSENGER VEHICLE TIRES MUST CONFORM TO FEDERAL SAFETY REQUIRE-MENTS IN ADDITION TO THESE GRADES .
Quality grades can be found, where applica- ble, on the tire sidewall between the treadshoulder and maximum section width. Forexample: Treadwear 200 Traction AA Temperature A
TREADWEARThe treadwear grade is a comparative rating based on the wear rate of the tire when testedunder controlled conditions on a specified gov-ernment test course. For example, a tire graded150 would wear one and one half (1 ½) times aswell on the government course as a tire graded100. The relative performance of tires dependsupon the actual conditions of their use, however,and many depart significantly from the norm dueto variation in driving habits, maintenance practi-ces and differences in road characteristics andclimate.
TRACTIONThe traction grades, from highest to lowest, areAA, A, B, and C, as measured under controlledconditions on specified government test surfacesof asphalt and concrete. A tire marked C mayhave poor traction performance. The tractiongrade assigned to this tire is based on braking (straight-ahead) traction tests and is not a meas-ure of cornering (turning) traction.
WARNING
The traction grade assigned to this tire is based on braking (straight-ahead) tractiontests and is not a measure of cornering (turn-ing) traction.
TEMPERATUREThe temperature grades are A (the highest), B, and C, representing the tire's resistance to thegeneration of heat and its ability to dissipate heatwhen tested under controlled conditions on aspecified indoor laboratory test wheel. Sustainedhigh temperature can cause the material of thetire to degenerate and reduce tire life, and exces-sive temperature can lead to sudden tire failure.The grade C corresponds to a minimum level ofperformance that all passenger vehicle tires mustmeet under the Federal Motor Safety StandardNo. 109. Grades B and A represent higher levelsof performance on the laboratory test wheel thanthe minimum required by law.
WARNING
The temperature grade for this tire is estab- lished for a tire that is properly inflated andnot overloaded. Excessive speed, under-infla-tion, or excessive loading, either separately orin combination, can cause heat buildup andtire failure.
Snow tires and chains
The use of snow chains and/or winter tires can help improve traction in winter driving conditions.
Snow chains can be used on your Volvo with the following restrictions:
• Snow chains should be installed on frontwheels only. Use only Volvo approved snowchains.
• If accessory, aftermarket or "custom" tiresand wheels are installed and are of a size dif-ferent than the original tires and wheels,chains in some cases CANNOT be used.Sufficient clearances between chains andbrakes, suspension and body componentsmust be maintained.
• Some strap-on type chains will interfere withbrake components and therefore CANNOTbe used.
• All Wheel Drive models
: Snow chains
should only be installed on the front wheels.
• Certain size tires may not allow the assemblyof snow chains/traction devices.
Consult your Volvo retailer for additional snowchain information.

WHEELS AND TIRES

CAUTION
•Snow chains should not be used on wheels larger than 19".
• Always follow the chain manufacturer'sinstallation instructions carefully. Installchains as tightly as possible andretighten periodically.
• Check local regulations regarding the useof snow chains before installing.
• Use single-sided snow chains only.
• Never exceed the chain manufacturer'sspecified maximum speed limit. (Underno circumstances should you exceed31 mph (50 km/h).
• Avoid bumps, holes or sharp turns whendriving with snow chains.
• The handling of the vehicle can beadversely affected when driving withchains. Avoid fast or sharp turns as wellas locked wheel braking.
Checking tire inflation pressure
Correct tire inflation pressure helps improve driv- ing stability, save fuel and increase the servicelife of the tires.
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 of vehi-cle control and increased risk of injury.
• Under-inflated tires reduce the load car-rying capacity of your vehicle.
Cold tiresInflation pressure should be checked when thetires are cold. The tires are considered to be cold when they have the same temperature as the sur-rounding (ambient) air. This temperature is normally reached after the vehicle has been parked for at least 3 hours. After driving a distance of approximately 1 mile (1.6 km), the tires are considered to be hot. If youhave to drive farther than this distance to pumpyour tire(s), check and record the tire pressurefirst and add the appropriate air pressure whenyou get to the pump. When weather temperature changes occur, tire inflation pressures also change. A 10-degree temperature drop causes a corresponding dropof 1 psi (7 kPa) in inflation pressure. Check yourtire pressures frequently and adjust them to theproper pressure, which can be found on the vehi-cle's tire information placard or certification label. If checking tire pressure when the tire is hot, never "bleed" or reduce air pressure. The tiresare hot from driving and it is normal for pressuresto increase above recommended cold pressures.A hot tire at or below recommended cold inflationpressure could be significantly under-inflated.
Recommended inflation pressures
Tire inflation placard
A tire inflation pressure placard is located on the driver's side B-pillar (the structural member at theside of the vehicle, at the rear of the driver's dooropening). This placard indicates the designation

||
WHEELS AND TIRES
486the inflation pressure recommended by the vehi- cle manufacturer on the vehicle placard or tireinflation pressure label. (If your vehicle has tiresof a different size than the size indicated on thevehicle placard or tire inflation pressure label, youshould determine the proper tire inflation pres-sure 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 malfunction, the tell-tale will flash for approximately one minute andthen remain continuously illuminated. Thissequence will continue upon subsequent vehiclestart-ups as long as the malfunction exists. Whenthe malfunction indicator is illuminated, the sys-tem may not be able to detect or signal low tirepressure 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 afterreplacing 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 panel
When the TPMS symbol illuminates, the following text messages may also be displayed:
•
Tire pressure low
•Tire pressure system Temporarily
unavailable
•Tire pressure system Service required
If TPMS cannot determine which tire(s) have low inflation pressure:
• All four tires will be shown as affected in thecenter display After changing wheels, always calibrate the sys-tem to avoid false warnings. TPMS does not replace the need for regular tire inspection and maintenance.
NOTE
If you change to tires with a different dimen- sion than the factory-installed ones, theTPMS system must be calibrated for thesetires. TPMS cannot be turned off.
WARNING
Incorrect inflation pressure could lead to tire failure, resulting in a loss of control of thevehicle.

MAINTENANCE AND SERVICING
542•
Dry the vehicle with a clean chamois and remember to clean the drain holes in thedoors and rocker panels.
• Tar spots can be removed with tar removerafter the vehicle has been washed.
• A stiff-bristle brush and lukewarm soapywater can be used to clean the wiper blades.Frequent cleaning of the windshield andwiper blades improves visibility considerablyand also helps prolong the service life of thewiper blades.
• Wash off the dirt from the underside (wheelhousings, fenders, etc).
• In areas of high industrial fallout, more fre-quent washing is recommended.
CAUTION
• During high pressure washing, the spray mouthpiece must never be closer to thevehicle than 13" (30 cm). Do not sprayinto the locks.
• Dirt, snow, etc., on the headlights canreduce lighting capacity considerably.Clean the headlights regularly, for exam-ple when refueling.
Special laminated panoramic roof cau-
tions:
• Always close the laminated panoramicroof and sun shade before washing yourvehicle.
• Never use abrasive cleaning agents onthe laminated panoramic roof.
• Never use wax on the rubber sealsaround the laminated panoramic roof.
NOTE
When washing the vehicle, remember to remove dirt from the drain holes in the doorsand sills.
Automatic car washes
•We do NOT recommend washing your vehi- cle in an automatic wash during the first few months (because the paint will not havehardened sufficiently).
• An automatic wash is a simple and quick wayto clean your vehicle, but it is worth remem-bering that it may not be as thorough aswhen you yourself go over the vehicle withsponge and water. Keeping the underbodyclean is most important, especially in the win-ter. Some automatic washers do not havefacilities for washing the underbody.
NOTE
Condensation may form temporarily on the inside of the lenses of exterior lights such asheadlights or taillights. This is normal and thelights are designed to withstand moisture.Normally, condensation will dissipate after thelights have been on for a short time.
