NOTE
The normal car jack is only designed for occa- sional, short-term use, such as when chang-ing a wheel after a puncture, changing to win-ter/summer wheels, etc. Only the jack for thespecific car model may be used to raise thecar. If the car is to be jacked up more often, orfor a longer time than is required just tochange a wheel, use of a garage jack is rec-ommended. In this instance, follow theinstructions for use that come with the equip-ment.
4. Place chocks in front of and behind the wheels which will remain on the ground to prevent them from rolling. Use heavy woodenblocks or large stones for example.
5. Screw together the towing eye with the wheel wrench * to the stop position.
IMPORTANT
The towing eye must be screwed all the way into the wheel bolt wrench.
6. Remove the plastic caps from the wheel
bolts with the intended tool.
7. Loosen the wheel bolts ½-1 turn anticlock- wise with the wheel wrench *.
WARNING
Never position anything between the ground and the jack, nor between the jack and thecar's jacking point.
IMPORTANT
The ground must be firm, smooth and level.
8. When raising the car, it is important that the
jack* or lifting arms are fitted in the intended
points on the car's underbody. The triangle markings in the plastic cover indicate thelocations of the jacking/lifting points. Thereare two jacking points on each side of thecar. There is a recess for the jack at eachpoint.

Crank up the jack
* so that it makes contact
with the car's jacking point. Check that the head of the jack is correctly positioned in thejacking point so that the bump in the centreof the head fits into the jacking point holeand the base is positioned vertically belowthe jacking point. Also make sure you turnthe jack so that the crank is as far away fromthe side of the car as possible, at which pointthe jack's arms are perpendicular to thedirection of the car.
WARNING
Never crawl under the car when it is raised on the jack. Passengers must leave the car when it is raised on the jack. If a wheel must bechanged in a trafficked environment, passen-gers must stand in a safe place.
9. Lift the car so that the wheel is free. Remove the wheel bolts and lift off the wheel.

WARNING
Never crawl under the car when it is raised on the jack. Passengers must leave the car when it is raised on the jack. If a wheel must bechanged in a trafficked environment, passen-gers must stand in a safe place.
1. Clean the contact surfaces between wheel and hub.
2. Put on the wheel. Tighten the wheel bolts thoroughly. Do not use lubricant on the threads of the
wheel bolts.
3. Lower the car so that the wheels cannot rotate. 4. Tighten the wheel bolts crosswise. It is impor-
tant that the wheel bolts are tightened prop- erly. Tighten to 140 Nm. Check the tighten-ing torque with a torque wrench.
5. Refit the plastic caps on the wheel bolts.
NOTE
• After a tyre has been inflated, always refit the dust cap in order to avoid damage tothe valve from gravel, dirt, etc.
• Only use plastic dust caps. Metal dustcaps can rust and become difficult tounscrew.

Wheel bolts
Wheel bolts are used to attach the wheels to the hubs.
IMPORTANT
The wheel bolts must be tightened to 140 Nm. Overtightening or loose tightening maydamage the nuts and the bolts.
Only use rims that are tested and approved by Volvo and which are Volvo genuine accessories. Check the tightening torque of the wheel bolts with a torque wrench. Do not use lubricant on the threads of the wheel
bolts.
Locking wheel bolts *In the foam block under the cargo area floor there is space for the sleeve for the lockablewheel bolts.

Spare wheel
*
The spare wheel, the Temporary spare type, can be used to temporarily replace a punctured nor-mal wheel.
The illustration is schematic - the shape of the foam block may vary depending on car model.
The spare wheel is located in the spare wheel well with the outside down. The same bolt runsthrough to secure the spare wheel and the foamblock. The foam block contains all tools forchanging a wheel, see the section "Tool kit". The car's handling may be altered by the use of the spare wheel. The spare wheel must bereplaced by a normal wheel as soon as possible. The spare wheel is smaller than the regular wheel, which will affect the car's ground clear-ance. Pay attention to high kerbs and do notmachine wash the car. •
Follow the manufacturer's recommended tyrepressure for the spare wheel.
• On all-wheel drive cars the drive on the rearaxle can be disconnected.
• If the spare wheel is fitted on the front axle, itis not possible to use snow chains at thesame time.
• The spare wheel must not be repaired.
IMPORTANT
• Never drive faster than 80 km/h (50 mph) with a spare wheel on the car.
• The car must never be driven fitted withmore than one "Temporary Spare" wheel.
Taking out the spare wheel1. Fold up the cargo area floor, from the rear
and forwards.
2. Undo the retaining screw.
3. Lift out the foam block with its tools.
4. Lift out the spare wheel.
Storing the punctured tyre1. Put the tools back in the foam block and lift the foam block back into the car.
2. Screw in the foam block using the mounting screws and then fold down the cargo area floor.
3. Place the punctured tyre in the cargo area.

Winter wheels
Winter wheels are adapted for winter road con- ditions.
Volvo recommends winter tyres with particular dimensions. Tyre dimensions are dependent onengine variant. When driving on winter tyres, thecorrect type of tyres must be fitted to all fourwheels.
NOTE
Contact a Volvo dealer for advice about which wheel rim and type of tyre are most suitable.
Tips for changing to winter tyresWhen summer and winter wheels are changed, mark which side of the car they were mounted on, for example L for left and R for right.
Studded tyresStudded winter tyres should be run in gently for 500-1000 km so the studs settle properly intothe tyres. This gives the tyre, and especially thestuds, a longer service life.
NOTE
The legal provisions for the use of studded tyres vary from country to country.
Tread depthRoad conditions with ice, slush and low tempera- tures place considerably higher demands on tyresthan summer conditions. Volvo therefore recom-mends not to drive on winter tyres that have atread depth of less than 4 mm.
Snow chainsVolvo recommends that snow chains are notused on wheel dimensions greater than18 inches. Mounting instructions are supplied with Volvo original snow chains. Snow chains may only be used on the front wheels (also applies to all-wheel drive cars).Never drive faster than 50 km/h (30 mph) withsnow chains. Avoid driving on bare ground as thiswears out both the snow chains and tyres.
WARNING
Use Volvo genuine snow chains or equivalent chains designed for the car model, and tyre and rim dimensions. Only single-sided snow
chains are permitted. In the event of uncertainty about the show chain, Volvo recommends that an authorisedVolvo workshop should be contacted. Thewrong snow chains may cause serious dam-age to the car and lead to an accident.

Jack*
Use the jack to raise the car when changing a wheel.
Only use the original jack when fitting a spare wheel or when changing between summer andwinter wheels. The jack's thread must always bewell greased.
IMPORTANT
The tools and jack * must be stored in the
intended location in the car's cargo area when not in use.
The jack needs to be cranked together to the correct position in order to have space.
NOTE
The normal car jack is only designed for occa- sional, short-term use, such as when chang-ing a wheel after a puncture, changing to win-ter/summer wheels, etc. Only the jack for thespecific car model may be used to raise thecar. If the car is to be jacked up more often, orfor a longer time than is required just tochange a wheel, use of a garage jack is rec-ommended. In this instance, follow theinstructions for use that come with the equip-ment.

Designations for tyre dimension, load index and speed rating.
The car has an approval for the complete vehicle with certain combinations of wheel rims andtyres.
Designation of dimensionsAll tyres have a dimension designation, such as:255/40 R19 100 W.
255 Tyre width (mm)
40 Ratio between tyre wall height and tyre width (%)
R Radial ply
19 Rim diameter in inches
100 Codes for the maximum permitted tyre load, tyre load index (LI)
W Speed rating for maximum permitted speed, speed rating (SS). (In this case 270 km/h (168 mph).)
Load indexEach tyre has a certain capacity to carry a load, a load index (LI). The car's weight determines theload capacity required of the tyres. The lowestpermitted load index is specified in a load indextable.
Speed ratingEach tyre can withstand a certain maximumspeed. Tyre speed rating, SS (Speed Symbol),must at least correspond with the car's topspeed. The table below shows the maximum per-mitted speed for each speed rating (SS). Theonly exception to these regulations is winter tyres3
, where a lower speed rating may be used.
If such a tyre is chosen, the car must not be driven faster than the speed rating of the tyre (forexample, class Q can be driven at a maximum of160 km/h (100 mph).) The top speed at whichthe car can be driven depends on road condi-tions, not the speed rating of the tyres.
NOTE
The maximum permitted speed is specified in the table.
Q 160 km/h (100 mph) (used only on win- ter tyres)
T 190 km/h (118 mph)
H 210 km/h (130 mph) V 240 km/h (149 mph)
W 270 km/h (168 mph) Y 300 km/h (186 mph)
