Location of jack and tools
Spare wheelThe spare wheel is only intended for tempo- rary use. Replace it with a normal wheel assoon as possible. The car's handling may bealtered by the use of the spare wheel. Thecorrect tire pressure for the spare wheel isstated in the tire pressure table on page 307and in the tire inflation placard on the driver'sside door jamb at the rear of the driver's dooropening.
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 “Tem-porary Spare” in use.
CAUTION
The vehicle must never be driven with more than one temporary spare wheel.
The spare wheel is located in the spare wheel well with the rim side down. There are twofoam blocks, one under the spare wheel andone over/inside. The upper one contains alltools. The same bolt runs through to secure the spare wheel and the foam blocks.
Taking out the spare wheel1. Open the floor hatch.
2. Undo the retaining bolt.
3. Lift out the foam block.
4. Lift out the spare wheel.The other two blocks can remain in the spare wheel well.
After useThe foam block and spare wheel must be replaced in the reverse order. Note the arrowon the upper foam block. It should point for-ward.
NOTE
If the floor hatch is not completely closed, the private locking feature (see page 65)will not function.
Changing a wheel1. Apply the parking brake and put the gear
selector in P.
2. Take out the jack*, lug wrench*, the tow- ing eyelet and the wheel cover removal tool* stowed under the floor of the trunk.
3. Remove the wheel cover (where applica- ble) using the removal tool or remove thewheel cover by hand.
4. Block the wheels that are on the ground with wooden blocks or large stones.

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 tobe extended under a vehicle suppor-ted by a jack.
• Use the jack intended for the vehiclewhen changing a tire. For any otherjob, use stands to support the vehicle.
• Apply the parking brake and put thegear selector in the Park (
P) position.
• Block the wheels standing on theground, use rigid wooden blocks orlarge stones.
• The jack should be kept well-greasedand clean, and should not be dam-aged.
• No objects should be placed betweenthe base of jack and the ground, orbetween the jack and the attachmentbar on the vehicle.
NOTE
The jack provided with your vehicle is intended to be used only in temporary sit-uations such as changing wheels in theevent of a flat tire. Only the jack that camewith your particular model should be usedto lift the vehicle. If the vehicle needs to belifted more frequently or for a prolongedperiod, using a garage jack or hoist is rec-ommended. Always follow this device’sinstructions for use.
Re-installing the wheel1. Clean the contact surfaces on the wheel
and hub.
2. Lift the wheel and place it on the hub.
Tighten the wheel nuts 3. Install the wheel nuts and tighten hand-
tight. Using the lug wrench, tighten cross- wise until all nuts are snug.
4. Lower the vehicle to the ground and alter- nately tighten the bolts crosswise to103 ft. lbs. (140 Nm).
5. Install the wheel cover (where applicable). The opening in the wheel cover for thetire's inflation valve must be positionedover the valve.

The appearance of the engine compartment may vary depending on engine model.
WARNING
The cooling fan (located at the front of the engine compartment, behind the radiator)may start or continue to operate (for up to6 minutes) after the engine has beenswitched off.
WARNING
Before performing any operations in the engine compartment, the ignition shouldalways be completely switched off (inmode 0, see page 87) and there should be
no remote keys in the passenger compart-ment. The gear selector should be in the P
(park) position. If the engine has been run-ning, wait until it has cooled before touch-ing any components in the engine com-partment. The distributor ignition system operates at very high voltages. Special safety precau-tions must be followed to prevent injury.Always turn the ignition off when:
• Replacing distributor ignition compo- nents e.g. plugs, coil, etc.
• Do not touch any part of the distributorignition system while the engine is run-ning. This may result in unintendedmovements and body injury.

Coolant
Location of the coolant reservoir
Normally, the coolant does not need to be changed. If the system must be drained, con-sult a trained and qualified Volvo servicetechnician. See page 376 for information on cooling sys- tem capacities.
CAUTION
• If necessary, top up the cooling sys- tem with Volvo Genuine Coolant/Anti-freeze only (a 50/50 mix of water andantifreeze).
• Different types of antifreeze/coolantmay not be mixed.
• If the cooling system is drained, itshould be flushed with clean water orpremixed anti-freeze before it is refilledwith the correct mixture of water/anti-freeze.
• The cooling system must always bekept filled to the correct level, and thelevel must be between the
MIN and
MAX marks. If it is not kept filled, there
can be high local temperatures in theengine which could result in damage.Check coolant regularly!
• Do not top up with water only. Thisreduces the rust-protective and anti-freeze qualities of the coolant and hasa lower boiling point. It can also causedamage to the cooling system if itshould freeze.
• Do not use chlorinated tap water in thevehicle's cooling system.
WARNING
• Never remove the expansion tank cap while the engine is warm. Wait until theengine cools.
• If it is necessary to top off the coolantwhen the engine is warm, unscrew theexpansion tank cap slowly so that theoverpressure dissipates.
Brake fluid
Location of the brake fluid reservoir
Checking the levelThe fluid reservoir is concealed under the round cover at the rear of the engine com-partment. The round cover must be removedfirst before the reservoir cap can beaccessed.

09 Maintenance and specifications
Fluids09
339
The brake fluid should always be between the MIN
and MAX marks on the inside of the res-
ervoir. Check, without removing the cap, thatthere is sufficient fluid in the reservoir. Fluid type : DOT 4 boiling point >536 °F
(>280 °C).Replace : The fluid should be replaced
according to the intervals specified in the Warranty and Service Records Informationbooklet. When driving under extremely hard condi- tions (mountain driving, etc), it may be neces-sary to replace the fluid more often. Consult atrained and qualified Volvo service technician. Always entrust brake fluid changing to a trained and qualified Volvo service technician.
WARNING
• If the fluid level is below the
MIN mark
in the reservoir or if a brake-related message is shown in the informationdisplay: DO NOT DRIVE . Have the car
towed to a trained and qualified Volvoservice technician and have the brakesystem inspected.
• Dot 4 should never be mixed with anyother type of brake fluid.
Filling1. Turn and open the cover.
2. Unscrew the reservoir cap and fill the
fluid. The level must be between the MIN
and MAX marks.
Power steering fluid
Check the level frequently. The fluid does not require changing. The fluid level must bebetween the MIN and MAX marks. For
capacities and recommended fluid grade, seepage 376.
WARNING
If a problem should occur in the power steering system or if the vehicle has noelectrical current and must be towed, it isstill possible to steer the vehicle. However,keep in mind that greater effort will berequired to turn the steering wheel.
CAUTION
Keep the area around the power steering fluid reservoir clean when checking.
