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.
CAUTION
• Snow chains should not be used on wheels larger than 18".
• 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

Wheel bolts
The wheel bolts hold the wheel in place.
CAUTION
Wheel bolts should be tightened to 103 ft. lbs. (140 Nm). Over-tightening could damagethe threads.
Only use wheels/rims that have been tested and approved by Volvo and are included in Volvo'sproduct range. Use a torque wrench to check that the wheel bolts are tightened correctly. Never lubricate the wheel bolts' threads.
Locking wheel bolts *A tool for removing locking wheel bolts can be found in the foam block under the cargo com-partment floor.

Removing a wheel
Wheel changes should always be carried out correctly.
1. Turn on the hazard warning flashers if the wheel change has to be done near passing traffic.
2. Apply the parking brake and put the gear selector in P.
CAUTION
Models with suspension and level con- trol *:
Turn this function off before raising the vehi- cle. To do so, go to
SettingsVehicleDeactivate Suspension & Leveling Controlin the center display's Top view.
WARNING
• The jack must correctly engage the jack attachment.
• Be sure the jack is on a firm, level, non-slippery surface.
• Never allow any part of your body to beextended under a vehicle supported by ajack.
• Use the jack intended for the vehicle whenchanging a tire. For any other job, usestands to support the vehicle.
• Apply the parking brake and put the gear selector in the Park (
P) position.
• Block the wheels standing on the ground, use rigid wooden blocks or large stones.
• The jack should be kept well-greased andclean, and should not be damaged.
• No objects should be placed between thebase of jack and the ground, or betweenthe jack and the attachment bar on thevehicle.
