Quality grading information
ALL PASSENGER VEHICLE TIRES MUST CONFORM TO FEDERAL SAFETYREQUIREMENTS IN ADDITION TO THESEGRADES Quality grades can be found, where appli- cable, on the tire sidewall between thetread shoulder and maximum sectionwidth. For example: Treadwear 200 Traction AA Temperature A
TREADWEARThe treadwear grade is a comparative rating based on the wear rate of the tire when tes-ted under controlled conditions on a specifiedgovernment test course. For example, a tiregraded 150 would wear one and one half(1 1/2) times as well on the governmentcourse as a tire graded 100. The relative per-formance of tires depends upon the actualconditions of their use, however, and manydepart significantly from the norm due to var-iation in driving habits, maintenance practicesand differences in road characteristics andclimate.
TRACTIONThe traction grades, from highest to lowest,are AA, A, B, and C, as measured under con-trolled conditions on specified governmenttest surfaces of asphalt and concrete. A tiremarked C may have poor traction perform-ance. The traction grade assigned to this tireis based on braking (straight-ahead) tractiontests and is not a measure of cornering (turn-ing) traction.
WARNING
The traction grade assigned to this tire is based on braking (straight-ahead) tractiontests and is not a measure of cornering(turning) traction.
TEMPERATUREThe temperature grades are A (the highest), B, and C, representing the tire's resistance tothe generation of heat and its ability to dissi-pate heat when tested under controlled con-ditions on a specified indoor laboratory testwheel. Sustained high temperature can causethe material of the tire to degenerate andreduce tire life, and excessive temperaturecan lead to sudden tire failure. The grade Ccorresponds to a minimum level of perform-ance that all passenger vehicle tires mustmeet under the Federal Motor Safety Stand-ard No. 109. Grades B and A represent higherlevels of performance on the laboratory testwheel than the minimum required by law.
WARNING
The temperature grade for this tire is established for a tire that is properly infla-ted and not overloaded. Excessive speed,under-inflation, or excessive loading, eitherseparately or in combination, can causeheat buildup and tire failure.

Location
IntroductionCertain models are equipped with a tire sealing system * that enables you to tempo-
rarily seal a hole in the tread surface and re- inflate a flat tire, or to adjust a tire’s inflationpressure. The system consists of an air compressor, a container for the sealing compound, wiring toconnect the system to the vehicle’s electricalsystem via one of the 12-volt sockets, and ahose used to connect the system to the tire’sinflation valve.
NOTE
The tire sealing system's compressor has been tested and approved by Volvo.
The 12-volt sockets are located in the front tunnel console, on the rear side of the centerconsole in the rear seat and in the cargoarea*, see page 235.
Accessing the tire sealing systemThe tire sealing system is stowed under thefloor of the cargo area. To access it:
1. Lift the floor hatch in the cargo area.
2. Lift out the tire sealing system.
NOTE
• The tire sealing system is only intended to seal holes on the tire’stread area, not the sidewall.
• Tires with large holes or tears cannotbe repaired with the tire sealing sys-tem.
• After use, stow the tire sealing systemproperly to help prevent rattling.
WARNING
• After using the tire sealing system, the vehicle should not be driven fartherthan approximately 120 miles (200km).
• Have the tire inspected by a trainedand qualified Volvo service technicianas soon as possible to determine if itcan be permanently repaired or mustbe replaced.
• The vehicle should not be driven fasterthan 50 mph (80 km/h) while using atire that has been temporarily repairedwith the tire sealing system.
• After using the tire sealing system,drive carefully and avoid abrupt steer-ing maneuvers and sudden stops.

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.

6. Connect the electrical wire to the nearest
12-volt socket in the vehicle.
NOTE
Be sure that none of the other 12-volt sockets is being used while the compres-sor is in operation.
7. 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 sure thevehicle is parked in a well ventilated place,or outdoors, before using the system.
8. Start the tire sealing system’s compres-sor by pressing the on/off switch to posi- tion I.
WARNING
• Never stand next to the tire being infla- ted when the compressor is in opera-tion.
• If cracks, bubbles, etc. form on the tire,switch off the compressor immediately.
• If there is visible damage to the sidewallor the rim, the tire cannot be repaired.The vehicle should not be driven if thisoccurs. Contact a towing service orVolvo On Call Roadside Assistance ifapplicable.
NOTE
The air pressure gauge will temporarily show an increase in pressure to approxi-mately 88 psi (6 bar) while the sealingcompound is being pumped into the tire.The pressure should return to a normallevel after approximately 30 seconds.
9. Within seven minutes, inflate the tire to
between 22—44 psi (1.8—3.0 bar). Switch off the compressor briefly to get aclear reading from the pressure gauge.
CAUTION
The compressor should not be used for more than 10 minutes at a time to avoidoverheating.
WARNING
If the pressure remains below 22 psi (1.8 bar) after approximately sevenminutes, turn off the compressor. In thiscase, the hole is too large to be sealed andthe vehicle should not be driven.
10. Switch off the compressor and discon- nect the electrical wire from the 12-volt socket.
11. 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.

12. Immediately drive the vehicle for approxi-
mately 2 miles (3 km) at a maximum speed of 50 mph (80 km/h) to distributethe sealing compound in the tire.
CAUTION
If your vehicle is equipped with the Tire Pressure Monitoring System (TPMS), theuse of the sealing compound may lead toincorrect tire pressure readings or in rarecases, damage to the tire pressure sensor.Use the tire sealing system to check andadjust the damaged tire's inflation pres-sure.
NOTE
•Safely stow the tire sealing system in a convenient place as it will soon beused again to check the tire’s inflationpressure.
• The empty bottle of sealing compoundcannot be removed from the bottleholder. Consult a trained and qualifiedVolvo service technician to have thebottle removed and properly disposedof.
WARNING
If heavy vibrations, unsteady steering behavior, or noises should occur whiledriving, reduce speed and park the vehiclein a safe place. Recheck the tire forbumps, cracks, or other visible damage,and recheck its inflation pressure. If thepressure is below 19 psi (1.3 bar), do notcontinue driving. Have the vehicle towedto a trained and qualified Volvo servicetechnician.
Stage 2: Checking inflation pressure1. Connect the tire sealing system as
described in stage 1.
2. Refer to the inflation pressure table in this chapter for the correct inflation pressure. If the tire needs to be inflated, start thetire sealing system’s compressor. If nec-essary, 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.
WARNING
If you interrupt your trip for more than 1 hour, check the inflation pressure in thedamaged tire again before continuing.
Replacing the sealing compound container
The sealing compound container must be replaced if:
• the tire sealing system has been used to repair a tire
• the container’s expiration date haspassed (see the date on decal).
NOTE
• After use, the sealing compound bot- tle, the hose, and certain other systemcomponents must be replaced. Pleaseconsult your Volvo retailer for replace-ment parts.
• If the sealing compound bottle’s expi-ration date has passed, please take itto a Volvo retailer or a recycling stationthat can properly dispose of harmfulsubstances.

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.
