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.
10. Within seven minutes, inflate the tire tobetween 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.
11. Switch off the compressor and discon-nect the electrical wire from the 12-volt socket. 12. 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.
13. 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 tables for the correct inflation pressure. If the tire needs to be inflated, start the tire sealing

system’s compressor. If necessary, release air from the tire by turning the airrelease 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.
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 position 0 (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 tables for the correct inflation pressure. If the tire needsto be inflated, start the tire sealing sys-tem’s compressor (press the on/offswitch to position I). If necessary, releaseair from the tire by turning the air releaseknob counterclockwise.

7. Raise the vehicle until the wheel to be changed is lifted off the ground.
8. Unscrew the wheel bolts completely and carefully remove the wheel so as not todamage the threads on the studs.
NOTE
To avoid excessive wear and the necessity of rebalancing, mark and reinstall wheelsin the same location and position as beforeremoval. To lessen the chance of imbal-ance, each wheel hub is equipped with aguide stud to ensure that a removed wheelcan be reinstalled in its original position (aswhen changing over to winter tires/wheels).
CAUTION
•The vehicle must not be driven with wheels of different dimensions or witha spare tire other than the one thatcame with the vehicle. The use of dif-ferent size wheels can seriously dam-age your vehicle's transmission.
• Correct tightening torque on wheelbolts must be observed.
• The wheel bolts should never begreased or lubricated.
• Extended, chromed wheel bolts mustnot be used with steel rims, as theymake it impossible to fit the hub caps.
Installing the wheel1. Clean the contact surfaces on the wheel
and hub.
2. Lift the wheel and place it on the hub.
3. Install the wheel bolts and tighten hand- tight. Using the lug wrench, tighten cross- wise until all bolts 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).
WARNING
• The jack must correctly engage the bar in the jack attachment. The vehicle'sweight must not rest on the jackattachment. See illustration "Attachingthe jack" on the previous page.
• 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 replacing a wheel. For any otherjob, use stands to support the side ofthe vehicle being worked on.
• Apply the parking brake and put thegear selector in the (
P)ark 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.

203
The tire pressure monitoring system
1
uses
sensors mounted in the tire valves to check inflation pressure levels. When the vehicle ismoving at a speed of approximately 20 mph(30 km/h) or faster, these sensors transmitinflation pressure data to a receiver located inthe vehicle.
USA – FCC ID: MRXG403MA4 A
This device complies with part 15 of the
FCC rules. Operation is subject to the fol- lowing conditions: (1) This device may notcause harmful interference, and (2) thisdevice must accept any interferencereceived, including interference that maycause undesired operation. When low inflation pressure is detected, TPMS will light up the tire pressure warn-ing light (also referred to as a telltale) in theinstrument panel (see page 61), and willdisplay a message in the text window. Thewording of this message is determined bythe degree of inflation pressure loss.
A On certain models, the FCC code is MRXTG315AM04
When low inflation pressure is detected, TPMS will light up the tire pressure warning light
(also referred to as a telltale) in the instrument panel and will display one of the following messages in the text window:
LOW
TIRE PRESS. CHECK TIRES or VERY LOW
TIRE PRESSURE.
NOTE
If a fault occurs in TPMS, the tire pressure warning light will flash for approximately 1 minute and
TIRE PRESS SYST
SERVICE REQUIRED will be displayed.
Each tire, including the spare (if provided), should be checked monthly when cold andinflated to the inflation pressure recom-mended by the vehicle manufacturer on thevehicle placard or tire inflation pressure label.(If your vehicle has tires of a different sizethan the size indicated on the vehicle placardor tire inflation pressure label, you shoulddetermine the proper tire inflation pressure forthose tires.) As an added safety feature, your vehicle has been equipped with a tire pressure monitor-ing system (TPMS) that illuminates a low tirepressure telltale when one or more of yourtires is significantly under-inflated. Accord-ingly, when the low tire pressure telltale illu-minates, you should stop and check yourtires as soon as possible, and inflate them to the proper pressure. Driving on a significantlyunder-inflated tire causes the tire to overheatand can lead to tire failure. Under-inflationalso reduces fuel efficiency and tire tread life,and may affect the vehicle's handling andstopping ability. Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driv-er's responsibility to maintain correct tirepressure, even if under-inflation has notreached the level to trigger illumination of theTPMS low tire pressure telltale. Your vehicle has also been equipped with a TPMS malfunction indicator to indicate whenthe system is not operating properly. TheTPMS malfunction indicator is combined withthe low tire pressure telltale. When the sys-tem detects a malfunction, the telltale willflash for approximately one minute and thenremain continuously illuminated. Thissequence will continue upon subsequentvehicle start-ups as long as the malfunctionexists. When the malfunction indicator is illu-minated, the system may not be able todetect or signal low tire pressure as intended.TPMS malfunctions may occur for a variety ofreasons, including the installation of replace-ment or alternate tires or wheels on the vehi-cle that prevent the TPMS from functioning

properly. Always check the TPMS malfunc- tion telltale after replacing one or more tiresor wheels on your vehicle to ensure that thereplacement or alternate tires and wheelsallow the TPMS to continue to function prop-erly.
NOTE
TPMS indicates low tire pressure but does not replace normal tire maintenance. Forinformation on correct tire pressure, pleaserefer to the tire inflation pressure table inthis chapter or consult your Volvo retailer.
Erasing warning messagesWhen a low tire pressure warning message has been displayed, and the tire pressurewarning light has come on:
1. Use a tire pressure gauge to check theinflation pressure of all four tires.
2. Re-inflate the tire(s) to the correct pres- sure (consult the tire pressure placard or the table see page 183).
3. Drive the vehicle for several minutes at a speed of 20 mph (30 km/h) or faster.
> This will erase the warning text and thewarning light will go out.
WARNING
Incorrect inflation pressure could lead to tire failure, resulting in a loss of control ofthe vehicle.
Changing wheels with TPMSPlease note the following when changing or replacing the factory installed TPMS wheels/tires on the vehicle:
• Only the factory-mounted wheels are equipped with TPMS sensors in thevalves.
• If the vehicle is equipped with a tempo-rary spare tire, this tire does not have aTPMS sensor.
• If wheels without TPMS sensors are mounted on the vehicle,
TIRE PRESS
SYST. SERVICE REQUIRED will be dis-
played each time the vehicle is driven above 25 mph (40 km/h) for 10 minutes ormore.
• Once TPMS sensors are properly instal-led, the warning message should notreappear.
• Volvo recommends that TPMS sensorsbe fitted on all wheels used on the vehi-cle. Volvo does not recommend movingsensors back and forth between sets ofwheels.
NOTE
If a tire is changed or if the TPMS sensor is moved to another wheel, the sensor’svalve and valve core should be replaced.
CAUTION
When inflating tires with TPMS valves, press the pump's mouthpiece straightonto the valve to help avoid bending orotherwise damaging the valve.
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 183), for exam-ple, if higher inflation pressure is necessarywhen transporting heavy loads, etc. To recalibrate:
1. Switch off the engine.
2. Inflate the tires to the desired pressure
and turn the ignition key to position I or II
(see page 145 for additional information).
3. Turn the thumb wheel on the left-side steering wheel lever until
Tire pressure
Calibration appears in the display.

Repeat steps 1-3 to turn TPMS on again.
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 not more 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.
WARNING
•
SST tires should only be mounted by service technicians who are familiarwith tires of this type.
• SST tires may only be mounted onvehicles equipped with TPMS.
• Do not drive faster than 50 mph(80 km/h) if TPMS indicates that a tirehas lost inflation pressure.
• Do not drive farther than 50 miles(80 km) before replacing a damagedSST tire.
• Drive carefully and avoid e.g., hardbraking or fast turns.
• SST tires must be replaced if they aredamaged. A tire of this type cannot berepaired.
