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.

MAINTENANCE AND SERVICING
512bering that it may not be as thorough as when 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.
CAUTION
When using an automatic car wash in which the vehicle has to be able to roll freely, theauto-hold brake function must be deactivated.If this is not done, the brakes will automati-cally be applied when the vehicle is stationary. To deactivate this function:
1. Drive the vehicle into the car wash
2. Turn off the auto-hold function using the
control on the center console
3. Turn off the parking brake's automatic function in the center display's Top view (tap
Settings, tap My CarElectric
Parking Brake and deselect Auto
Activate Parking Brake)
4. Put the gear selector in N
5. Switch off the ignition by turning the start knob to STOP and holding it in this posi-
tion for at least 4 seconds
The vehicle will then be able to roll freely.
CAUTION
• Before driving into an automatic car wash, turn off the optional rain sensor toavoid damaging the windshield wipers.
• Make sure that side view mirrors, auxiliarylamps, etc, are secure, and that anyantenna(s) are retracted or removed. Oth-erwise there is risk of the machine dis-lodging them.
• Chromed wheels:
Clean chrome-plated
wheels using the same detergents usedfor the body of the vehicle. Aggressivewheel-cleaning agents can permanentlystain chrome-plated wheels.
WARNING
• When the vehicle is driven immediately after being washed, apply the brakes,including the parking brake, several timesin order to remove any moisture from thebrake linings.
• Engine cleaning agents should not beused when the engine is warm. This con-stitutes a fire risk.
Exterior componentsVolvo recommends the use of special cleaningproducts, available at your Volvo retailer, forcleaning colored plastic, rubber, or ornamental

CAUTION
•
When loading the vehicle, the maximum gross vehicle weight and permissible axleweights may not be exceeded.
• The maximum trailer weights listed areonly applicable for altitudes up to 3280 ft(1,000 m) above sea level. With increas-ing altitude the engine power and there-fore the car's climbing ability are impairedbecause of the reduced air density, sothe maximum trailer weight has to bereduced accordingly. The weight of thecar and trailer must be reduced by 10%for every further 3280 ft (1,000 m) (orpart thereof).
