pressure telltale. When the system detects a mal-function, the telltale will flash for approximatelyone minute and then remain continuously illumi-nated. This sequence will continue upon subse-quent vehicle start-ups as long as the malfunc-tion exists. When the malfunction indicator is illu-minated, the system may not be able to detect orsignal low tire pressure as intended.
TPMS malfunctions may occur for a variety ofreasons, including the installation of replacementor alternate tires or wheels on the vehicle thatprevent the TPMS from functioning properly.
Always check the TPMS malfunction telltale afterreplacing one or more tires or wheels on yourvehicle to ensure that the replacement or alter-nate tires and wheels allow the TPMS to con-tinue to function properly.
Messages in the instrument panel
If tire pressure is too low, the low tire pressurewarning symbol is shown in the instrument panelalong with a message.
Tire pressure low Check tires, calibrateafter fill
Tire pressure system Temporarilyunavailable
Tire pressure system Service required
To keep in mind
Always calibrate the system after changingwheels or adjusting tire pressure. See the tirepressure placard on the driver's side B pillarfor Volvo-recommended tire pressures.
If you switch to a tire of another size than thefactory-mounted tires, the system must becalibrated for these tires to avoid false warn-ings.
If a spare wheel8 is used, it is possible thatthe tire pressure monitoring system will notwork correctly due to the differencesbetween the wheels.
The system does not replace the need forregular tire inspection and maintenance.
It is not possible to deactivate the tire pres-sure monitoring system.
WARNING
Incorrect inflation pressure could lead totire failure, which could cause the driverto lose control of the vehicle.
The system cannot predict sudden tiredamage.

Action when warned of low tirepressure
When the system for monitoring inflation pres-
sure 13 detects low inflation pressure in a tire,immediate action is required.
If the system's indicator symbol illumi-nates and the message Tire pressurelow is displayed, check the tire pres-sure and inflate if necessary.
1. Switch off the ignition.
2. Check the inflation pressure on all four tiresusing a tire pressure gauge.
3.Inflate the tire to the correct inflation pres-sure; see the tire pressure placard on thedriver's side B pillar for recommended pres-sures for factory-mounted tires.
4. Through calibration of the system via thecenter display after the tire pressure hasbeen adjusted.
Please be aware that the indicator symbolwill 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 thevalve 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 totire failure, which could cause the driverto lose control of the vehicle.
The system cannot predict sudden tiredamage.

Spare wheel15
The spare wheel is a Temporary Spare and canbe 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 changeand 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 bepurchased 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).

Snow tires
Snow tires are designed for winter driving.
Volvo recommends snow tires with specificdimensions. 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 bestchoice of rims and tires.
Tips for changing snow tires
When switching between regular tires and snowtires, mark the tires according to which side theywere mounted on, e.g. L for left and R for right.
Studded tires
Studded tires should be broken in by driving500–1000 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 studdedtires vary from country to country.
Tread depth
Road 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).

Snow chains
Using snow chains and/or snow tires can helpimprove traction in winter driving conditions.
WARNING
Use Volvo genuine snow chains or equivalentsnow chains that are suitable for the vehiclemodel 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.
