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
•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.

Introduction
NOTE
USA – FCC ID: KR5S122780002 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.
The tire pressure monitoring system1
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. When low inflation pressure is detected or if a sensor is not functioning properly, 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:
Tire pressure
low or
Tire needs air now.
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 tothe 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 functioningproperly. 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 wheels

allow 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 the
inflation pressure of all four tires.
2. Re-inflate the tire(s) to the correct pres- sure (consult the tire pressure placard or the inflation pressure table on page 316.
3. In certain cases, it may be necessary to drive the vehicle for several minutes at aspeed of 20 mph (30 km/h) or faster. Thiswill erase the warning text and the warn-ing 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. If the message is still displayed,drive the vehicle for several minutes at aspeed of 20 mph (30 km/h) or faster toerase the message.
• 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.
CAUTION
When inflating tires with TPMS valves, press the pump's mouthpiece straightonto the valve to help avoid bending orotherwise damaging the valve.
CAUTION
• After pumping the tires, always rein- stall the valve cap to help avoid dam-age to the valve from dirt, gravel, etc.
• Use plastic valve caps only. Metalcaps could corrode and become diffi-cult to remove.
