NOTE
Always remember to calibrate the Tire Pres- sure Monitoring System when the wheelshave been changed or the tire inflation pres-sure has been corrected according to the tirepressure decal or tire inflation pressure table. If correct reference values have not been set, the system cannot issue low tire pressurealerts correctly. The vehicle must be stationary with the engine running to access the calibration but-ton and to start the calibration process.
WARNING
The exhaust gases contain carbon monoxide, which is invisible and odorless but very poi-sonous. For this reason, always perform thecalibration procedure outdoors or in a work-shop with exhaust gas evacuation equipment.

Action when warned of low tirepressure
When the tire pressure monitoring system, Tyre Pressure Monitoring System (TPMS), detectslow pressure in one or more of the vehicle'stires, the driver will be alerted that action is nee-ded.
If the system's indicator symbol illumi- nates and the message Tire pressure
low is displayed, check the tire pres-
sure and inflate if necessary.
1. Switch off the ignition.
2. Check the inflation pressure on all four tires using a tire pressure gauge.
3. Inflate the tire to the correct pressure (see the tire pressure decal on the driver's side door pillar).
4. Through calibration of the system via the center display after the tire pressure hasbeen adjusted. Please be aware that the indicator symbol will not go out until the low tire pressure hasbeen corrected and the system has beenrecalibrated.
NOTE
To help prevent incorrect inflation pressure, pressure should be checked when the tiresare cold. The tires are considered to be coldwhen they have reached the same tempera-ture as the ambient temperature (about 3hours after the vehicle was last driven). Afterdriving for a few kilometers, the tires will warmup and the pressure will increase.
NOTE
• After inflating a tire, always replace the valve cap to help prevent valve damagecaused by gravel, dirt, etc.
• Use plastic valve caps only. Metal capscould corrode and become difficult toremove.
WARNING
•Incorrect inflation pressure could lead to tire failure, which could cause the driverto lose control of the vehicle.
• The system cannot predict sudden tiredamage.

Spare wheel11
The spare wheel is a Temporary spare and can be used to temporarily replace a punctured tireon one of the vehicle's regular wheels.
The spare tire is only intended for temporary use. Replace it with a normal wheel as soon as possi-ble. The driving characteristics of the vehicle change and ground clearance reduces when the sparewheel is used. Do not wash the vehicle in anautomatic car wash while using the TemporarySpare. The recommended tire pressure must be main- tained regardless of at which position the tempo-rary spare wheel is used on the vehicle. If the spare wheel is damaged, a new one can be purchased from a Volvo retailer.
WARNING
Current legislation prohibits the use of the "Temporary Spare" tire other than as a tem-porary replacement for a punctured tire. Itmust be replaced as soon as possible by astandard tire. Road holding and handling maybe affected with the "Temporary Spare" inuse. Do not drive faster than 80 km/h(50 mph).
11 Not available on all models.

WARNING
•The vehicle must never be driven with more than one "Temporary spare" tiremounted.
• Driving with a spare wheel may alter thedriving characteristics of the vehicle.Replace the spare wheel with a normalwheel as soon as possible.
• The spare wheel is smaller than the nor-mal wheel, which affects the vehicle'sground clearance. Watch for high curbsand do not wash the vehicle in an auto-matic car wash when a spare wheel ismounted.
• Follow the manufacturer's recommendedtire inflation pressure for the spare wheel.
• On all-wheel drive vehicles, the drive onthe rear axle can be disconnected.
• If the spare wheel is mounted on thefront axle, snow chains must not be used.
• The spare wheel must not be repaired.
CAUTION
The vehicle must not be driven with wheels of different dimensions or with a spare tire otherthan the one that came with the vehicle. Theuse of different size wheels can seriouslydamage your vehicle's transmission.
This illustration is general. The shape and design of the foam block may vary depending on vehicle model.
The spare wheel is located in the spare wheel well with the outside of the wheel facing down-ward. The same bolt runs through both the sparewheel and foam block to hold them into place.The foam block contains all tools needed tochange a wheel.

Snow tires
Snow tires are designed for winter driving.
Volvo recommends snow tires with specific dimensions. The tire dimensions vary dependingon engine type. When driving with snow tires, thecorrect type of tires must be mounted on all fourwheels.
NOTE
Contact a Volvo dealer for advice on the best choice of rims and tires.
Tips for changing snow tiresWhen switching between regular tires and snow tires, mark the tires according to which side they were mounted on, e.g. L for left and R for right.
Studded tiresStudded tires should be broken in by driving 500–1000 km (300–600 miles) slowly and gen-tly to help the studs settle properly in the tires.This gives the tire, and especially the studs, alonger service life.
NOTE
Regulations regarding the use of studded tires vary from country to country.
Tread depthRoad conditions with ice, slush and low tempera- tures place considerably higher demands on tiresthan summer conditions. Volvo therefore recom-mends not driving on snow tires that have a treaddepth of less than 4 mm (0.15 inch).
Related information
• When changing wheels (p. 522)
• Winter driving (p. 425)
• Tread wear indicator (p. 511)
Snow chains
Using snow chains and/or snow tires can help improve traction in winter driving conditions.
WARNING
Use Volvo genuine snow chains or equivalent snow chains that are suitable for the vehicle model and the tire and wheel sizes. Only one-
sided snow chains are permitted.
If uncertain about snow chains, Volvo recom- mends contacting an authorized Volvo work-shop. Use of the wrong snow chains couldcause serious damage to the vehicle andresult in an accident.
