Tire sealing system–temporarily repairing a flat tire
Temporarily repairing a flat tire is done in two stages:
• Stage 1:
The hole is sealed by pumping
sealing compound into the tire. The car is then driven a short distance to distributethe sealing compound in the tire.
NOTE
Do not remove any foreign objects (nails, etc.) from the tire before using the sealingsystem.
• Stage 2:
The tire’s inflation pressure is
checked and adjusted if necessary.
WARNING
• Never leave the tire sealing system unattended when it is operating.
• Keep the tire sealing system awayfrom children.
• Be sure the vehicle is parked safely offthe road and away from moving traffic.
• Apply the parking brake.
Stage 1: Sealing the hole1. Peel off the speed limit sticker and affix it
to the steering wheel hub where it will be clearly visible to the driver.
2. Ensure that the on/off switch is in posi- tion 0 (the 0 side of the switch should be
pressed down).
WARNING
Contact with the sealing compound may cause skin irritation. If contact occurs,wash the affected area immediately withsoap and water.
3. Unscrew the orange cover over the bottle holder and unscrew the cap on the bottle of sealing compound.
NOTE
Do not break the seal on the bottle. This occurs automatically when the bottle isscrewed into the holder.
4. Screw the bottle into the bottle holder.
WARNING
The bottle is equipped with a catch to keep it securely in place and help preventsealing compound leakage. Once in place,the bottle cannot be unscrewed. This mustbe done by a trained and qualified Volvoservice technician.
5. Remove the valve cap from the tire’sinflation valve and screw the tire sealing system’s hose connector onto the valveas tightly as possible by hand.

Inflating tires
The tire sealing system can be used to inflate the tires. To do so:
1. Park the car in a safe place.
2. The compressor should be switched off.
Ensure that the on/off switch is in position0 (the 0 side of the switch should be
pressed down).
3. Take out the electrical wire and hose.
4. Remove the valve cap from the tire’s inflation valve and screw the hose con- nector onto the valve as tightly as possi-ble by hand.
5. Connect the electrical wire to the nearest 12-volt socket in the vehicle.
6. Start the vehicle’s engine.WARNING
• The vehicle’s engine should be running when the tire sealing system is used toavoid battery drain. Therefore, be surethe vehicle is parked in a well ventilatedplace, or outdoors, before using thesystem. The parking brake should besecurely applied and the gear selectorshould be in the
P (park) position.
• Children should never be left unatten-ded in the vehicle when the engine isrunning.
7. Check the tire’s inflation pressure on the
gauge. Switch off the compressor briefly to get a clear reading from the pressuregauge.
8. Refer to the tire inflation table in this chapter for the correct inflation pressure.If the tire needs to be inflated, start thetire sealing system’s compressor (pressthe on/off switch to position I). If neces-sary, release air from the tire by turningthe air release knob counterclockwise.
CAUTION
The compressor should not be used for more than 10 minutes at a time to avoidoverheating.
9. Turn off the compressor (press the on/off switch to position 0) when the correct
inflation pressure has been reached.
10. Unscrew the hose from the tire’s inflation valve and reinstall the valve cap.
CAUTION
•After pumping the tires, always reinstall the valve cap to help avoid damage tothe valve from dirt, gravel, etc.
• Use plastic valve caps only. Metal capscould corrode and become difficult toremove.
11. Disconnect the electrical wire from the
12-volt socket.

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 316and 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 67)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 cargoarea.
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
•Never expose the battery to open flame or electric spark.
• Do not smoke near the battery.
• Battery fluid contains sulfuric acid. Donot allow battery fluid to contact eyes,skin, fabrics or painted surfaces. Ifcontact occurs, flush the affected areaimmediately with water. Obtain medi-cal help immediately if eyes are affec-ted.
NOTE
The life of the battery is shortened if it becomes discharged repeatedly.
Maintenance
•
Use a screw driver to open the caps or cover and a flashlight to inspect the level.
• If necessary, add distilled water. The levelshould never be above the indicator.
• The fluid level should be checked if thebattery has been recharged.
• After inspection, be sure the cap overeach battery cell or the cover is securelyin place.
• Check that the battery cables are cor-rectly connected and properly tightened. •
Never disconnect the battery when theengine is running, or when the key is inthe ignition. This could damage the vehi-cle's electrical system.
• The battery should be disconnected fromthe vehicle when a battery charger isused directly on the battery.
• To help keep the battery in good condi-tion, the vehicle should be driven for atleast 15 minutes a week or connected toa charger with an automatic chargingfunction.
• If the battery is fully discharged a numberof times, this may shorten its service life.Keeping the battery fully charged helpsprolong its service life.
• The service life of a battery is affected byfactors such as driving conditions and cli-mate. Extreme cold may also furtherdecrease the battery’s starting capacity.
• Because the battery’s starting capacitydecreases with time, it may be necessaryto recharge it if the vehicle is not drivenfor an extended period of time or if thevehicle is usually only driven short dis-tances.
CAUTION
•Always use distilled or deionized water (battery water).
• Never fill above the level mark in thecell.
