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 front wheels 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 snow chain information.
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 the tires 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

MAINTENANCE AND SERVICING

Automatic car washes
•We do NOT recommend washing your car in an automatic wash during the first fewmonths (because the paint will not havehardened sufficiently).
• An automatic wash is a simple and quick wayto clean your car, but it is worth rememberingthat it may not be as thorough as when youyourself go over the car with sponge andwater. Keeping the underbody clean is mostimportant, especially in the winter. Someautomatic washers do not have facilities forwashing the underbody.
NOTE
Condensation may form temporarily on the inside of the lenses of exterior lights such asheadlights, fog lights, or taillights. This is nor-mal and the lights are designed to withstandmoisture. Normally, condensation will dissi-pate after the lights have been on for a shorttime.
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 cleaning products, available at your Volvo retailer, forcleaning colored plastic, rubber, or ornamentalcomponents such as chromed strips on the exte- rior of your vehicle. The instructions for usingthese products should be followed carefully. Sol-vents or stain removers should not be used.
CAUTION
•
Avoid waxing or polishing plastic or rub- ber components
• Polishing chromed strips can wear awayor damage the surface
• Polishes containing abrasive substancesshould not be used
