4. Tighten the wheel bolts in a crisscross pat-
tern (as shown in illustration). It is impor- tant that the wheel bolts are securelytightened. Tighten to 140 Nm (103 ft. lbs.).Use a torque wrench to check torque.
5. Press the plastic covers onto the wheelbolts.
6. Check the tire inflation pressure and store the new inflation pressure in the tire pres- sure monitoring system *.
WARNING
The wheel bolts may need to be tightened again several days after a wheel change.Temperature fluctuations and vibrationscan cause them to loosen slightly.
NOTE
After inflating a tire, always replace the valve cap to help prevent valve damagecaused by gravel, dirt, etc.
Use plastic valve caps only. Metal capscould corrode and become difficult toremove.

Spare wheel 13
The spare wheel is a Temporary Spare and can be used to temporarily replace a punc- tured tire on one of the vehicle's regularwheels.
The spare tire is only intended for temporary use. Replace it with a normal wheel as soon aspossible. The driving characteristics of the vehicle change and ground clearance reduces whenthe spare wheel is used. Do not wash the vehi-cle in an automatic car wash while using theTemporary Spare. The recommended tire pressure must be maintained regardless of at which position thetemporary 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 atemporary replacement for a puncturedtire. It must be replaced as soon as possi-ble by a standard tire. Road holding andhandling may be affected with the "Tempo-rary Spare" in use. Do not drive faster than80 km/h (50 mph).

WARNING
The vehicle must never be driven with more than one "Temporary Spare" tiremounted.
Driving with a spare wheel may alterthe driving characteristics of the vehi-cle. Replace the spare wheel with anormal wheel as soon as possible.
The spare wheel is smaller than thenormal wheel, which affects the vehi-cle's ground clearance. Watch for highcurbs and do not wash the vehicle inan automatic car wash when a sparewheel is mounted.
Follow the manufacturer's recom-mended tire inflation pressure for thespare wheel.
On all-wheel drive vehicles, the driveon the rear axle can be disconnected.
If the spare wheel is mounted on thefront axle, snow chains must not beused.
The spare wheel must not be repaired.
CAUTION
The vehicle must not be driven with wheels of different dimensions or with a spare tireother than the one that came with the vehi-cle. The use of different size wheels canseriously damage your vehicle's transmis-sion.

Accessing the spare wheel
This illustration is generic and appearance may vary.
The spare tire is located in the spare wheel well under the cargo compartment with theoutside of the wheel facing downward. Thespare tire is secured with a bolt that goesthrough the tire and attaches it to the body.The foam block contains all tools needed tochange a wheel.
1. Lift the rear edge of the cargo compart-
ment floor.
2. Unscrew the retaining bolt.
3. Lift out the spare wheel.

Stowing a flat tire1. Screw the spare tire's retaining bolt backon.
CAUTION
Do not attempt to unscrew the lower part of the retaining bolt if it is attached to thebody, as this could cause it to break. If the retaining bolt becomes dislodged from its lower attachment point in thebody under the spare tire, replace it in thehole and turn clockwise to secure it again.
2. Put the tools back in their correct posi-tions in the foam block.
3. Then lower the trunk/cargo compartment floor and place the punctured tire in the trunk/cargo compartment.

Snow tires
Snow tires are designed for winter driving conditions.
Volvo recommends snow tires with specific dimensions. The tire dimensions vary depend-ing on engine type. When driving with snowtires, the correct type of tires must be moun-ted on all four wheels.
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 whichside they were mounted on, e.g. L for left and
R for right.
Studded tiresStudded tires should be broken in by driving500–1000 km (300–600 miles) slowly andgently to help the studs settle properly in thetires. This gives the tire, and especially thestuds, a longer service life.
NOTE
Regulations regarding the use of studded tires vary from country to country.
Tread depthRoad conditions with ice, slush and low tem- peratures place considerably higher demandson tires than summer conditions. Volvo there-fore recommends not driving on snow tiresthat have a tread depth of less than 4 mm(0.15 inch).

Snow chainsUsing snow chains and/or snow tires can help improve traction in winter driving condi-tions.
Volvo does not recommend use of snow chains on wheel dimensions larger than18 inches.
WARNING
Use Volvo genuine snow chains or equiva- lent snow chains that are suitable for thevehicle model and the tire and wheel sizes.Only one-sided snow chains are permit-
ted. If uncertain about snow chains, Volvo rec- ommends contacting an authorized Volvoworkshop. Use of the wrong snow chainscould cause serious damage to the vehicleand result in an accident.
CAUTION
Snow chains can be used on the vehicle, with the following restrictions:
Always follow the manufacturer'sinstallation instructions carefully. Installchains as tightly as possible andretighten periodically.
Only put snow chains on the frontwheels (also applies to all-wheel drivevehicles).
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, sus-pension and body components mustbe maintained.
Check local regulations regarding theuse of snow chains before installing.
Never exceed the snow chain manu-facturer's specified maximum speedlimit. Under no circumstances shouldyou exceed 50 km/h (30 mph).
Avoid bumps, holes or sharp turnswhen driving with snow chains.
Avoid driving on surfaces withoutsnow as this wears out both the snowchains and the tires.
The handling of the vehicle can be adversely affected when driving withchains. Avoid fast or sharp turns aswell as 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 system14
The temporary tire sealing system can be used to seal a puncture in a tire or to checkand adjust the pressure in the tire. Models equipped with a spare wheel 15
do not
have the tire sealing system.
WARNING
California Proposition 65 Operating, servicing and maintaining a pas- senger vehicle can expose you to chemi-cals including engine exhaust, carbon mon-oxide, phthalates, and lead, which areknown to the State of California to causecancer and birth defects or other reproduc-tive harm. To minimize exposure, avoidbreathing exhaust, do not idle the engineexcept as necessary, service your vehicle ina well ventilated area and wear gloves orwash your hands frequently when servicingyour vehicle. For more information go towww.P65Warnings.ca.gov/passenger-vehicle.
The tire sealing system consists of a compres- sor and a bottle containing sealing compound.The sealing functions as a temporary repair.
NOTE
The sealing compound effectively seals tires with punctures in the tread but maynot be able to fully seal tires with punctu-res in the sidewall. Do not use the tire seal-ing system on tires with large tears, cracksor similar damage.
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.
Sealing compound expiration dateThe sealing compound bottle must be replaced if its expiration date has passed (seethe decal on the bottle). Handle the old bottleas hazardous waste.

Do not remove the hose while the tiresealing system is being used.
1. Turn on the vehicle's hazard warning flashers if the tire sealing system is to beused in an area with traffic. If the puncture was caused by a nail or similar object, do not remove it. It will helpseal the hole. 2. Peel off the speed limit sticker from the
side of the compressor. Affix the decal to aclearly visible location on the windshieldto remind the driver not to exceed thisspeed limit. Do not drive faster than80 km/h (50 mph) while using a tire thathas been temporarily repaired with the tiresealing system.
3. Make sure the switch is in the 0 (Off)
position and take out the electric cableand the hose.
4. Unscrew the orange cover on the com- pressor and unscrew the cap on the seal-ing compound bottle.
5. Screw the bottle onto the bottle holder as far as possible. The bottle and the bottle holder are equip- ped with catches to help prevent the seal-ing compound from leaking. Once the bot-tle is screwed into place into the bottleholder, it cannot be unscrewed. The bottle can only be removed by a workshop 17
.
WARNING
Do not unscrew the bottle. It is equipped with a catch to prevent leakage. 6. Unscrew the tire's valve cap and screw
the hose's valve connector as far as possi- ble onto the valve. Be sure the air release valve on the com- pressor's hose is completely closed.
7. Connect the electrical cable to the nearest 12 V outlet and start the vehicle.
NOTE
Make sure that none of the vehicle's other 12 V sockets are used while the compres-sor is running.

5268. Start the compressor by moving the
switch to the I (On) position.
WARNING
Never stand next to a tire being inflated with the compressor. If cracks, bulges, etc.form on the tire, switch off the compressorimmediately. The vehicle should not bedriven. Call roadside assistance to have thevehicle towed to a workshop for inspec-tion/replacement of the tire. Volvo recom-mends an authorized workshop.
NOTE
When the compressor first starts, air pres- sure may temporarily increase up to 6 bar(88 psi) but should decrease again afterapproximately 30 seconds.
9. Inflate the tire for 7 minutes.
CAUTION
To help avoid overheating, the compressor should never be used for more than10 minutes at a time.
10. Switch off the compressor and check the
inflation pressure using the air pressure gauge. The inflation pressure should bebetween 1.8 bar (22 psi) and 3.5 bar(51 psi). If the inflation pressure is toohigh, use the air release valve to releaseair.
WARNING
If pressure falls below 1.8 bar (22 psi), the hole in the tire may be too large. The vehi-cle should not be driven. Call roadsideassistance to have the vehicle towed to aworkshop for inspection/replacement ofthe tire. Volvo recommends an authorizedworkshop.
11. Switch off the compressor and remove the electrical cable.
12. Unscrew the hose from the tire's valve and screw the valve cap back on.
NOTE
After inflating a tire, always replace the valve cap to help prevent valve damagecaused by gravel, dirt, etc.
Use plastic valve caps only. Metal capscould corrode and become difficult toremove.
13. Put the protective hose cover onto the
hose to help prevent leakage of any resid- ual sealing compound. Return the equip-ment to the cargo compartment.
14. Immediately drive the vehicle at least 3 km (2 miles) at a maximum speed of80 km/h (50 mph) to allow the sealingcompound to seal the tire, and thenrecheck the inflation pressure.
WARNING
During the tire's first revolution, some seal- ing compound may spray out of the punc-ture hole. Before driving away, make surethat no one is near the vehicle who couldbe sprayed with sealing compound. Makesure no one is within 2 meters(7 feet) ofthe vehicle.
15. Rechecking the inflation pressure Connect the hose to the tire's valve and screw the hose connector onto the valveas far as possible. The compressor mustbe switched off.
