WARNING
•Under-inflation is the most common cause of tire failure and may result insevere tire cracking, tread separation, or"blow-out," with unexpected loss of vehi-cle control and increased risk of injury.
• Under-inflated tires reduce the load car-rying capacity of your vehicle.
When weather temperature changes occur, tire inflation pressures also change. A 10-degreetemperature drop causes a corresponding dropof 1 psi (7 kPa) in inflation pressure. Check yourtire pressures frequently and adjust them to theproper pressure, which can be found on the vehi-cle's tire information placard or certification label.

Tire inflation – checking pressure
Inflation pressure should be checked when the tires are cold.
Cold tires
The tires are considered to be cold when they have the same temperature as the sur-rounding (ambient) air. This temperature is normally reached after the vehicle has been parked for at least 3 hours. After driving a distance of approximately 1 mile (1.6 km), the tires are considered to be hot. If youhave to drive farther than this distance to pumpyour tire(s), check and record the tire pressurefirst and add the appropriate air pressure whenyou get to the pump. If checking tire pressure when the tire is hot, never "bleed" or reduce air pressure. The tiresare hot from driving and it is normal for pressuresto increase above recommended cold pressures.A hot tire at or below recommended cold inflationpressure could be significantly under-inflated.
To check inflation pressure:
1. Remove the cap from the valve on one tire, then firmly press the tire gauge onto the valve.
2. Add air to reach the recommended air pres- sure. 3. Replace the valve 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.
4. Visually inspect the tires to make sure there
are no nails or other objects embedded that could puncture the tire and cause an air leak.
5. Check the sidewalls to make sure there are no gouges, cuts, bulges or other irregulari-ties.
6. Repeat this procedure for each tire, including the spare 3
.
NOTE
• If you overfill the tire, release air by push- ing on the metal stem in the center of thevalve. Then recheck the pressure withyour tire gauge.
• Some spare tires (available as an acces-sory) require higher inflation pressurethan the other tires. Consult the tire infla-

Snow tires/studded tires5
Owners who live in or regularly commute through areas with sustained periods of snow oricy driving conditions are strongly advised to fitsuitable winter tires to help retain the highestdegree of traction.
Tires for winter use:
• It is important to install winter tires on all four wheels to help retain traction during corner-ing, braking, and accelerating. Failure to doso could reduce traction to an unsafe level oradversely affect handling.
• Do not mix tires of different design as thiscould also negatively affect overall tire roadgrip.
• Winter tires wear more quickly on dry roadsin warm weather. They should be removedwhen the winter driving season has ended.
• Studded tires should be run-in 300 – 600 miles (500 – 1000 km) during whichthe vehicle should be driven as smoothly aspossible to give the studs the opportunity toseat properly in the tires. The tires shouldhave the same rotational direction through-out their entire lifetime.
NOTE
Please consult state or provincial regulations restricting the use of studded winter tiresbefore installing such tires.
Tire pressure monitoring - overview
Volvo provides two different systems to monitor tire pressure: Tire Pressure Monitoring System(TPMS) or Tire Monitor.
Determining which tire monitoring system is in your vehicle
To see which system is installed in your vehicle, press the MY CAR button on the center console.
Go to
SettingsCar settings.
• If your vehicle has a menu called
Tire
monitoring, see Tire Monitor - introduction
(p. 317).
• If your vehicle has a menu called
Tire
pressure, see Tire Pressure Monitoring Sys-
tem (TPMS) – general information (p. 320).
Introduction
Each tire, including the spare 6
(if provided),
should be checked monthly when cold and infla- ted to the inflation pressure recommended by thevehicle manufacturer on the vehicle placard ortire inflation pressure label. (If your vehicle hastires of a different size than the size indicated onthe vehicle placard or tire inflation pressure label,you should determine the proper tire inflationpressure for those tires.) As an added safety feature, your vehicle has been equipped with a tire pressure monitoring

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 inflation – pressure table
The following tire pressures are recommended by Volvo for your vehicle. Refer to the tire infla- tion placard (see Tire inflation – general informa-tion (p. 308) for its location) for information spe-
cific to the tires installed on your vehicle at thefactory. Some of the tire sizes listed here may not be available for all models in all markets.
