process. The temporary spare
1
should also
be replaced at 6-year intervals, even if it has never been used. A tire's age can be determined by the DOT stamp on the sidewall (see the illustration). A tire with e.g., visible cracks or discoloration should be replaced immediately.
Tread wear indicator
G021829
The tires have wear indicator strips running across or parallel to the tread. The letters TWI
are printed on the side of the tire. Whenapproximately 1/16" (1.6 mm) is left on thetread, these strips become visible and indi-cate that the tire should be replaced. Tires with less than 1/16" (1.6 mm) tread offer verypoor traction. When replacing worn tires, it is recommended that the tire be identical in type (radial) andsize as the one being replaced. Using a tire ofthe same make (manufacturer) will preventalteration of the driving characteristics of thevehicle.
Improving tire economy
•
Maintain correct tire pressure. See the tire inflation table on page 307.
• Drive smoothly: avoid fast starts, hardbraking and tire screeching.
• Tire wear increases with speed.
• Correct front wheel alignment is veryimportant.
• Unbalanced wheels impair tire economyand driving comfort.
• Tires must maintain the same direction ofrotation throughout their lifetime.
• When replacing tires, the tires with themost tread should be mounted on therear wheels to reduce the chance of over-steer during hard braking.
• Hitting curbs or potholes can damage thetires and/or wheels permanently.
Summer and winter tires
G021778
The arrows shows the direction of rotation of the tire
• When switching between summer and winter tires, mark the tires to indicatewhere they were mounted on the car,e.g., LF = left front, RR = right rear
• Tires with tread designed to roll in onlyone direction are marked with an arrowon the sidewall.
• Incorrectly mounted tires impair the car'sbraking properties and ability to forceaside rain, snow and slush.

G010753
Federal law mandates that tire manufacturers place standardized information on the side-wall of all tires (see the illustration). The following information is listed on the tire sidewall: The tire designation:
NOTE
Please be aware that the following tire designation is an example only and that
this particular tire may not be available onyour vehicle.
1. 215: the width of the tire (in millimeters)
from sidewall edge to sidewall edge. The larger the number, the wider the tire.
2. 65: The ratio of the tire's height to its
width in percent.
3. R: Radial tire (the designation RF and the
symbol indicate that the vehicle is
equipped with optional self-supporting run flat tires 1
. See page 327 for more
information about these tires).
4. 15: The diameter of the wheel rim (in
inches).
5. 95: The tire's load index. In this example,
a load index of 95 equals a maximum load of 1521 lbs (690 kg).
6. H: The tire's speed rating, or the maxi-
mum speed at which the tire is designedto be driven for extended periods of time,carrying a permissible load for the vehi-cle, and with correct inflation pressure.For example, H indicates a speed ratingof 130 mph (210 km/h).
NOTE
The tire's load index and speed rating may not appear on the sidewall because theyare not required by law.
7. M+S or M/S = Mud and Snow, AT = All
Terrain, AS = All Season
8. U.S. DOT Tire Identification Number (TIN)
: This begins with the letters "DOT"
and indicates that the tire meets all fed- eral standards. The next two numbers orletters are the plant code where it wasmanufactured, the next two are the tiresize code and the last four numbers rep-resent the week and year the tire wasbuilt. For example, 1510 means that thetire was manufactured during week 15 of2010. The numbers in between are mar-keting codes used at the manufacturer'sdiscretion. This information helps a tiremanufacturer identify a tire for safetyrecall purposes.
9. Tire Ply Composition and Material Used
: Indicates the number of plies indi-
cates or the number of layers of rubber- coated fabric in the tire tread and side-wall. Tire manufacturers also must indi-cate the ply materials in the tire and thesidewall, which include steel, nylon, poly-ester, and others.

* Option/accessory, for more information, see Introduction.319
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

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.

Removing a wheel
G017464
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.

Tire Pressure Monitoring System (TPMS)
08
* Option/accessory, for more information, see Introduction.327
NOTE
• If you change to tires with a different recommended inflation pressure, theTPMS system must be recalibrated tothese tires. On U.S. models, this mustbe done by a trained and qualifiedVolvo service technician. On Canadianmodels, see the following section"Recalibrating TPMS."
• If a tire is changed, or if the TPMS sen-sor is moved to another wheel, thesensor's seal, nut, and valve coreshould be replaced.
• When installing TPMS sensors, thevehicle must be parked for at least15 minutes with the ignition off. If thevehicle is driven within 15 minutes, aTPMS error message will be displayed.
Recalibrating TPMS (Canadian models only)*
In certain cases, it may be necessary to reca- librate TPMS to conform to Volvo's recom-mended tire inflation pressures (see the infla-tion pressure table on page 307), for exam-ple, if higher inflation pressure is necessarywhen transporting heavy loads, etc. This is done in the vehicle's menu system. See page 199 for a description of the menusystem. To recalibrate:
1. Switch off the engine.
2. Inflate the tires to the desired pressure
and put the ignition in mode I or II (see
page 87 for additional information).
3. Press the MY CAR key in the center con-
sole control panel and select
Settings
Car settingsTyre pressure
4. Press OK/MENU , select Calibrate tyre
pressure and press OK/MENU again.
5. Drive the vehicle at a speed above 25 mph (40 km/h) continuously for at least 10 minutes.
> When the calibration message is nolonger displayed, TPMS has been recalibrated to the new inflation pres-sure.
Activating/deactivating TPMS
(Canadian models only)*
1. Switch off the engine.
2. Put the ignition in mode I or II (see page
87 for additional information).
3. Press the MY CAR key in the center con-
sole control panel and select
Settings
Car settingsTyre pressure
4. Select Tyre pressure system and press
OK/MENU to turn the system on or off.
Self-supporting run flat tires (SST)*
Self-supporting run flat tires are available as optional equipment. The vehicle must beequipped with the Tire Pressure MonitoringSystem (TPMS) if tires of this type are instal-led. Tires of this type have specially reinforced sidewalls that make it possible to continuedriving to a limited extent even though the tirehas lost some or all of its inflation pressure.These tires are mounted on special rims (nor-mal tires can also be mounted on these rims). If an SST tire loses inflation pressure, the yel- low TPMS symbol illuminates in the instru-ment panel and a text message is also dis-played. If this happens, reduce speed to notmore than 50 mph (80 km/h). The tire shouldbe replaced as soon as possible. Drive carefully; it may be difficult to determine which tire is damaged. To find the damagedtire, check the inflation pressure in all fourtires.
