Winter driving
Check your vehicle before the approach of cold weather.
The following advice is worth noting:
• Make sure that the engine coolant contains 50 percent antifreeze. Any other mixture willreduce freeze protection. This gives protec-tion against freezing down to –31 °F(–35 °C). The use of "recycled" antifreeze isnot approved by Volvo. Different types ofantifreeze must not be mixed.
• Volvo recommends using only genuine Volvoantifreeze in your vehicle's radiator.
• Try to keep the fuel tank well filled – thishelps prevent the formation of condensationin the tank. In addition, in extremely coldweather conditions it is worthwhile to addfuel line de-icer before refueling.
• The viscosity of the engine oil is important.Oil with low viscosity (thinner oil) improvescold-weather starting as well as decreasingfuel consumption while the engine is warm-ing up. Full synthetic 0W-30 oil is recom-mended for driving in areas with sustainedlow temperatures.
• The load placed on the battery is greater dur-ing the winter since the windshield wipers,lighting, etc., are used more often. Moreover,the capacity of the battery decreases as thetemperature drops. In very cold weather, apoorly charged battery can freeze and be damaged. It is therefore advisable to checkthe state of charge more frequently andspray an anti-rust oil on the battery posts.
• Volvo recommends the use of snow tires onall four wheels for winter driving.
• To prevent the washer fluid reservoir fromfreezing, add washer solvents containingantifreeze. This is important since dirt is oftensplashed on the windshield during winterdriving, requiring the frequent use of thewashers and wipers. Volvo Washer Solventshould be diluted as follows: Down to 14 °F(–10 °C): 1 part washer solvent and 4 partswater Down to 5 °F (–15 °C): 1 part washersolvent and 3 parts water Down to 0 °F(–18 °C): 1 part washer solvent and 2 partswater Down to –18 °F (–28 °C): 1 partwasher solvent and 1 part water.
• Use Volvo Teflon Lock Spray in the locks.
• Avoid using de-icing sprays as they cancause damage to the locks.

Towing eyelet
When used, the towing eyelet should always be securely attached in the openings on the rightside of the front and rear bumpers. There arecovers over these attachment points.
Using the towing eyelet
Take out the towing eyelet, which is stored under the floor in the trunk.

Maximum Load : Indicates the maximum
load in pounds and kilograms that can be carried by the tire. Refer to the vehicle's tireinformation placard located on the B-Pillarfor the correct tire pressure for your vehicle.
11. Treadwear, Traction, and Temperaturegrades .
12. Maximum permissible inflation pressure: the greatest amount of air pressure that should ever be put in the tire. This limit is setby the tire manufacturer.
Speed SymbolA tire's Speed Symbol (SS) indicates the maxi-mum speed for which the tire has been certifiedand should be at least equivalent to the vehicle'stop speed. Winter tires, with our without studs, are excep- tions and may use a lower SS. When winter tiresare installed, the vehicle may not be driven fasterthan the tires' SS. The vehicle's speed should always be determined by the posted speed limit and traffic and roadconditions, not the tire's SS. The following table indicates the maximum per- missible speed for each SS.
Speed Symbol
M 81 mph (130 km/h)
Q 100 mph (160 km/h)
T 118 mph (190 km/h)
H 130 mph (210 km/h)
V 149 mph (240 km/h)
W 168 mph (270 km/h)
Y 186 mph (300 km/h)
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.
Wheel (rim) designations Wheel and rim dimensions are shown in the fol- lowing table.
The vehicle has been certified with certain combi- nations of wheels and tires. The following table shows an
example of wheel
dimensions: 8x18x42. This particular wheel may not be available on your vehicle.
8 Wheel width in inches
18 Wheel diameter in inches
42 Offset in mm (distance from the center of the wheel to the wheel's contact surface on the hub)

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.
