Spare wheel11
The spare wheel is a Temporary spare and can be used to temporarily replace a punctured tireon one of the vehicle's regular wheels.
The spare tire is only intended for temporary use. Replace it with a normal wheel as soon as possi-ble. The driving characteristics of the vehicle change and ground clearance reduces when the sparewheel is used. Do not wash the vehicle in anautomatic car wash while using the TemporarySpare. The recommended tire pressure must be main- tained regardless of at which position the tempo-rary spare wheel is used on the vehicle. If the spare wheel is damaged, a new one can be purchased from a Volvo retailer.
WARNING
Current legislation prohibits the use of the "Temporary Spare" tire other than as a tem-porary replacement for a punctured tire. Itmust be replaced as soon as possible by astandard tire. Road holding and handling maybe affected with the "Temporary Spare" inuse. Do not drive faster than 80 km/h(50 mph).
11 Not available on all models.

WARNING
•The vehicle must never be driven with more than one "Temporary spare" tiremounted.
• Driving with a spare wheel may alter thedriving characteristics of the vehicle.Replace the spare wheel with a normalwheel as soon as possible.
• The spare wheel is smaller than the nor-mal wheel, which affects the vehicle'sground clearance. Watch for high curbsand do not wash the vehicle in an auto-matic car wash when a spare wheel ismounted.
• Follow the manufacturer's recommendedtire inflation pressure for the spare wheel.
• On all-wheel drive vehicles, the drive onthe rear axle can be disconnected.
• If the spare wheel is mounted on thefront axle, snow chains must not be used.
• The spare wheel must not be repaired.
CAUTION
The vehicle must not be driven with wheels of different dimensions or with a spare tire otherthan the one that came with the vehicle. Theuse of different size wheels can seriouslydamage your vehicle's transmission.
This illustration is general. The shape and design of the foam block may vary depending on vehicle model.
The spare wheel is located in the spare wheel well with the outside of the wheel facing down-ward. The same bolt runs through both the sparewheel and foam block to hold them into place.The foam block contains all tools needed tochange a wheel.

Snow tires
Snow tires are designed for winter driving.
Volvo recommends snow tires with specific dimensions. The tire dimensions vary dependingon engine type. When driving with snow tires, thecorrect type of tires must be mounted on all fourwheels.
NOTE
Contact a Volvo dealer for advice on the best choice of rims and tires.
Tips for changing snow tiresWhen switching between regular tires and snow tires, mark the tires according to which side they were mounted on, e.g. L for left and R for right.
Studded tiresStudded tires should be broken in by driving 500–1000 km (300–600 miles) slowly and gen-tly to help the studs settle properly in the tires.This gives the tire, and especially the studs, alonger service life.
NOTE
Regulations regarding the use of studded tires vary from country to country.
Tread depthRoad conditions with ice, slush and low tempera- tures place considerably higher demands on tiresthan summer conditions. Volvo therefore recom-mends not driving on snow tires that have a treaddepth of less than 4 mm (0.15 inch).

Snow chains
Using snow chains and/or snow tires can help improve traction in winter driving conditions.
WARNING
Use Volvo genuine snow chains or equivalent snow chains that are suitable for the vehicle model and the tire and wheel sizes. Only one-
sided snow chains are permitted.
If uncertain about snow chains, Volvo recom- mends contacting an authorized Volvo work-shop. Use of the wrong snow chains couldcause serious damage to the vehicle andresult in an accident.

CAUTION
Snow chains can be used on the vehicle, with the following restrictions:• Volvo recommends not using snowchains on wheel dimensions larger than18 inches.
• Always follow the manufacturer's installa-tion instructions carefully. Install chainsas tightly as possible and retighten peri-odically.
• Only put snow chains on the front wheels(also applies to all-wheel drive vehicles).
• If accessory, aftermarket or "custom"tires and wheels with different dimen-sions than the original tires and wheelsare used, snow chains in some casesmay NOT be used. Sufficient distancebetween the chains and brakes, suspen-sion and body components must bemaintained.
• Check local regulations regarding the useof snow chains before installing.
• Never exceed the snow chain manufac-turer's specified maximum speed limit.Under no circumstances should youexceed 50 km/h (30 mph).
• Avoid bumps, holes or sharp turns whendriving with snow chains.
• Avoid driving on surfaces without snow as this wears out both the snow chains andthe tires.
• The handling of the vehicle can beadversely affected when driving withchains. Avoid fast or sharp turns as wellas locked wheel braking.
• Some types of strap-on chains affectbrake components and therefore mustNOT be used.
Consult a Volvo retailer for more information about snow chains.

Tire sealing system12
The temporary tire sealing system can be used to seal a puncture in a tire or to check andadjust the pressure in the tire. Models equipped with a spare wheel 13
do not
have the tire sealing system.
The tire sealing system consists of a compressor and a bottle containing sealing compound. Thesealing functions as a temporary repair.
NOTE
The sealing compound effectively seals tires with punctures in the tread but may not beable to fully seal tires with punctures in thesidewall. Do not use the tire sealing systemon tires with large tears, cracks or similardamage.
NOTE
The compressor is intended for temporary tire sealing and is approved by Volvo.
LocationThe tire sealing system is located in a foam block under the floor of the trunk.
