NOTE
• The placards shown indicate inflation pressure for the tires installed on thevehicle at the factory only.
• A certain amount of air seepage from thetires occurs naturally and tire pressurefluctuates with seasonal changes in tem-perature. Always check tire pressure reg-ularly.
•Use a tire gauge to check the tire inflation pressure, including the spare 2
, at least once
a month and before long trips. You are strongly urged to buy a reliable tire pressuregauge, as automatic service station gaugesmay be inaccurate.
• Use the recommended cold inflation pres-sure for optimum tire performance and wear.
• Under-inflation or over-inflation may causeuneven treadwear patterns.

system that illuminates a low tire pressure telltale (
) when one or more of your tires is signifi-
cantly under-inflated. Accordingly, when the low tire pressure telltale illuminates, you should stopand check your tires as soon as possible, andinflate them to the proper pressure. Driving on a significantly under-inflated tire cau- ses the tire to overheat and can lead to tire fail-ure. Under-inflation also reduces fuel efficiencyand tire tread life, and may affect the vehicle'shandling and stopping ability. Please note that atire pressure monitoring system is not a substi-tute for proper tire maintenance, and it is the driv-er's responsibility to maintain correct tire pres-sure, even if under-inflation has not reached thelevel to trigger illumination of the system's lowtire pressure telltale. Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when thesystem is not operating properly. The monitoringsystem's malfunction indicator is combined withthe low tire pressure telltale. When the system detects a malfunction, the tell- tale will flash for approximately one minute andthen remain continuously illuminated. Thissequence will continue upon subsequent vehiclestart-ups as long as the malfunction exists. Whenthe malfunction indicator is illuminated, the sys-tem may not be able to detect or signal low tirepressure as intended. System malfunctions may occur for a variety ofreasons, including the installation of replacementor alternate tires or wheels on the vehicle thatprevent the tire pressure monitoring system fromfunctioning properly. Always check the system's malfunction telltale after replacing one or more tires or wheels onyour vehicle to ensure that the replacement oralternate tires and wheels allow the system tocontinue to function properly.
NOTE
The system indicates low tire pressure but does not replace normal tire maintenance. Forinformation on correct tire pressure, pleaserefer to the tire inflation decal on the driver'sdoor opening or consult your Volvo retailer.
WARNING
Incorrect inflation pressure could lead to tire failure, resulting in a loss of control of thevehicle.

Tire Monitor - introduction (p. 309)
• Tire Pressure Monitoring System (TPMS) – general information (p. 312)
Tire Monitor - introduction Tire Monitor uses the rotational speed of the tires in combination with signal analysis of theABS sensor signals to determine if they areproperly inflated.
When a tire is under-inflated, its diameter (and consequently also its rotational speed) changes.By comparing the individual tires with each otherit is possible to determine if one or more tires areunder inflated. When low inflation pressure is detected or if the system is not functioning properly, Tire Monitorwill light up the tire pressure warning light (
) (also referred to as a telltale) in the
instrument panel and will display one of several messages in the text window, for example:
Tire
pressure low Check tires. Adjust the inflation
pressure and recalibrate if necessary.
NOTE
If a malfunction occurs in the system, the tire pressure warning light will flash for approxi-mately 1 minute and then remain illuminated.

NOTE
To help avoid incorrect tire inflation pressure, only inflate the tires when they are cold. Thetires are considered to be cold when theyhave the same temperature as the surround-ing (ambient) air. This temperature is normallyreached after the vehicle has been parked forat least 3 hours. After driving a distance ofapproximately 1 mile (1.6 km), the tires areconsidered to be hot.
CAUTION
•After inflating the tires, always reinstall the valve cap to help avoid damage to thevalve from dirt, gravel, etc.
• Use plastic valve caps only. Metal capscould corrode and become difficult toremove.
WARNING
•
Incorrect inflation pressure could lead to tire failure, resulting in a loss of control ofthe vehicle.
• Tire monitoring systems cannot indicatesudden tire damage caused by externalfactors (e.g., a blowout) in advance.
Related information
•Tire inflation – checking pressure (p. 301)
Tire Pressure Monitoring System (TPMS) – general information TPMS uses sensors mounted in the tire valves to check inflation pressure levels. When thevehicle is moving at a speed of approximately20 mph (30 km/h) or faster, these sensorstransmit inflation pressure data to a receiverlocated in the vehicle.

Tire Pressure Monitoring System (TPMS) – changing wheels
Please keep the following in mind when chang- ing or replacing the factory installed TPMSwheels/tires on the vehicle:
• Not all aftermarket wheels are equipped withTPMS sensors in the valves.
• If the vehicle is equipped with a temporaryspare tire, this tire does not have a TPMSsensor.
• If wheels without TPMS sensors are moun-ted on the vehicle, a text message will dis-played in the instrument panel each time thevehicle is driven above 20 mph (30 km/h) for10 minutes or more.
• Once TPMS sensors are properly installed,the warning message should not reappear. Ifthe message is still displayed, drive the vehi-cle for several minutes at a speed of 20 mph(30 km/h) or faster to erase the message.
• Volvo recommends that TPMS sensors befitted on all wheels used on the vehicle,including winter tires. Volvo does not recom-mend moving sensors back and forthbetween sets of wheels.
CAUTION
When inflating tires, press the pump's mouth- piece straight onto the valve to help avoidbending or otherwise damaging the valve.
CAUTION
•After inflating the tires, always reinstall the valve cap to help avoid damage to thevalve from dirt, gravel, etc.
• Use plastic valve caps only. Metal capscould corrode and become difficult toremove.
NOTE
•
If you change to tires with a different dimension than the factory-installed ones,the TPMS system must be reconfiguredfor these tires. This must be done by atrained and qualified Volvo service techni-cian.
• If a tire is changed, or if the TPMS sensoris moved to another wheel, the sensor'sseal, nut, and valve core should bereplaced.
• When installing TPMS sensors, the vehi-cle must be parked for at least15 minutes with the ignition off. If thevehicle is driven within 15 minutes, aTPMS error message will be displayed.

Tire sealing system* – sealing a
hole The tire sealing system can be used to tempo- rarily seal a hole in the tread surface of a tire.
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 position 0
(the 0 side of the switch should be pressed
down).
WARNING
Contact with the sealing compound may cause skin irritation. If contact occurs, washthe affected area immediately with soap andwater.
3. Unscrew the orange cover over the bottle holder on the compressor 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 as faras possible.
WARNING
The bottle is equipped with a catch to keep it securely in place and help prevent sealingcompound leakage. Once in place, the bottlecannot be unscrewed. This must be done by atrained and qualified Volvo service technician.
5. Remove the valve cap from the tire

WARNING
•Never stand next to the tire being inflated when the compressor is in operation.
• If cracks, bubbles, etc. form on the tire,switch off the compressor immediately.
• If there is visible damage to the sidewall orthe rim, the tire cannot be repaired. Thevehicle should not be driven if this occurs.Contact a towing service or Volvo On CallRoadside Assistance if applicable.
NOTE
The air pressure gauge will temporarily show an increase in pressure to approximately88 psi (6 bar) while the sealing compound isbeing pumped into the tire. The pressureshould return to a normal level after approxi-mately 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 a clearreading from the pressure gauge.
CAUTION
The compressor should not be used for more than 10 minutes at a time to avoid overheat-ing.
WARNING
If the pressure remains below 22 psi (1.8 bar) after approximately seven minutes, turn offthe compressor. In this case, the hole is toolarge to be sealed and the vehicle should notbe driven.
10. Switch off the compressor and disconnect the electrical wire from the 12-volt socket.
11. Unscrew the hose from the tire's inflation valve and put the cover on the hose back into place to help prevent seepage of residualsealing compound in the hose. Reinstall thevalve cap.
CAUTION
•After inflating the tires, always reinstall the valve cap to help avoid damage to thevalve 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 distribute the seal-ing compound in the tire.
CAUTION
If your vehicle is equipped with the Tire Pres- sure Monitoring System (TPMS), the use ofthe sealing compound may lead to incorrecttire pressure readings or in rare cases, dam-age to the tire pressure sensor. Use the tiresealing system to check and adjust the dam-aged tire's inflation pressure.
NOTE
• Safely stow the tire sealing system in a convenient place as it will soon be usedagain to check the tire
