Using snow chainsSnow chains may only be used on the front wheels (also applies to all-wheel drive cars).Never drive faster than 50 km/h with snowchains. Avoid driving on bare ground as thiswears out both the snow chains and tyres.
WARNING
Use Volvo genuine snow chains or equiva- lent chains designed for the car model,and tyre and rim dimensions. In the eventof uncertainty Volvo recommends that youconsult an authorised Volvo workshop.The wrong snow chains may cause seriousdamage to your car and lead to an acci-dent.

WARNING
19-inch wheels must never be used on
cars that are not equipped with the R-
Design or Sport chassis options. The use of 19-inch wheels on cars with standard
chassis constitutes a safety risk, with a
risk of vehicle damage, and it impairs thecar's driving characteristics.

Tyres - load index
Load index indicates a tyre's ability to carry a certain load. Each tyre has a certain capacity to carry a load, a load index (LI). The car's weight deter-mines the load capacity required of the tyres.Minimum permissible index is indicated in theload index table.

Tyres - speed ratings
Each tyre can withstand a certain maximum speed and therefore belongs to a particularspeed rating (SS - Speed Symbol). Tyre speed class must at least correspond with the car's top speed. Minimum speed rat-ing is indicated in the speed rating tablebelow. The only exception to these regula- tions is the winter tyre (p. 321) 1
, where a
lower speed rating may be used. If such a tyre is chosen, the car must not be drivenfaster than the speed rating of the tyre (forexample, class Q can be driven at a maxi-mum of 160 km/h). Traffic regulations deter-mine how fast a car can be driven, not thespeed rating of the tyres.
NOTE
The maximum permitted speed is speci- fied in the table.
Q160 km/h (used only on winter tyres)
T190 km/h

Changing wheels - removing wheels
The car's wheels can be changed for e.g. win- ter wheels/winter tyres.
Spare wheel*The following instructions only apply if aspare wheel has been purchased as an accessory for the car.
If the car is not equip-
ped with a spare wheel - see information about Emergency puncture repair (TMK) (p.333). The spare wheel (Temporary spare) is only intended for use temporarily and must bereplaced by an ordinary wheel as soon aspossible. The car's handling may be alteredby the use of the spare wheel. The sparewheel is smaller than the normal wheel. Thecar's ground clearance is affected accord-ingly. Pay attention to high kerbs and do notmachine wash the car. If the spare wheel isfitted on the front axle, you cannot use snowchains at the same time. On all-wheel drivecars the drive on the rear axle can be discon-nected. The spare wheel must not berepaired. The correct tyre pressure for the spare wheel is stated in the tyre pressure table (p. 407).
IMPORTANT
• Never drive faster than 80 km/h with a spare wheel on the car.
• The car must never be driven fittedwith more than one "TemporarySpare" wheel.
The spare wheel is supplied in a bag which must be secured on the cargo area floorusing straps.
Cars with four load retaining eyelets.
Turn the handle on the spare wheel bag out towards you. Attach the sewn-in tensioningstrap hooks in the front load retaining eyelets.Attach the long strap into one of the frontload retaining eyelets, run the strap diagonallyover the spare wheel and through the upperhandle. Tighten the short tensioning straponto the long one. Attach the rear load retain-ing eyelet and tighten.

Tyres - air pressure
Tyres can have different air pressures which are measured in bar.
Check the air pressure in the tyresThe tyre pressures must be checked everymonth.
• Tyre pressure for the car's recommended tyre dimension
• ECO pressure 2
NOTE
•
Check the tyre pressure when the tyres are cold. "Cold tyres" means thatthe tyres are at the same temperatureas the outdoor temperature. The tyreswill heat up and the tyre pressures willincrease after driving for a few kilome-tres.
• Tyre pressures which are too low willincrease fuel consumption, reduce tyreservice life and impair the car's han-dling. Driving with tyre pressureswhich are too low may lead to thetyres overheating and sustaining dam-age. Tyre pressures affect ride com-fort, road noise and steering.
• Tyre pressure decreases over time,this is a natural phenomenon. Tyrepressure also varies depending onambient temperature.
Tyre pressure label
G021830
The tyre pressure label on the driver's side door pillar (between frame and rear door)shows which pressures the tyres should haveat different loads and speed conditions. Thisis also specified in the tyre pressure table,see Tyres - approved tyre pressures (p. 407).
Fuel economy, ECO pressureIn order to obtain optimum fuel economy atspeeds below 160 km/h an ECO pressure isrecommended (applies to both full and lightload), see Tyres - approved tyre pressures (p.407).

Tyre pressure monitoring*
Tyre pressure monitoring (TPMS) (Tyre Pressure Monitoring System) 3
warns the
driver when the pressure is too low in one or more of the car's tyres. Tyre pressure monitoring uses sensors located inside the air valve in each wheel.When the car is driven at about 40 km/h thesystem detects the tyre pressure. If the pres- sure is too low then a warning lamp
in the
combined instrument panel illuminates and a message is shown in the information display. Both factory-fitted and optional wheels can be equipped with TPMS sensors in thevalves. If wheels without TPMS sensors are used or if a sensor has failed then
Tyre press. syst
Service required will be shown.
Always check the system after changing a wheel in order to ensure that replacementwheels work with the system. For information on the correct tyre pressure, see Tyres - air pressure (p. 328). The system does not replace normal tyre maintenance.
IMPORTANT
If a fault should arise in the tyre pressure system a warning lamp
in the com-
bined instrument panel will illuminate and a message will be shown. This can be forvarious reasons, e.g. fitting a wheel notequipped with a sensor adapted for Vol-vo's tyre pressure monitoring system.

Tyre pressure monitoring* - recommendations
Tyre pressure monitoring TPMS (Tyre Pressure Monitoring System) 7
warns the
driver when the pressure is too low in one or more of the car's tyres.
• Volvo recommends that TPMS sensors are fitted to all wheels on the car.
• Volvo recommends that sensors are notmoved between different wheels.
WARNING
When inflating a tyre equipped with TPMS, hold the nozzle of the pump directlyagainst the valve to avoid damaging thevalve.

Tyre pressure monitoring - driveable punctured tyres*
If SST (Self Supporting run flat Tires)* is selected, the car is also equipped with TPMS(p. 330). This type of tyre has a specially reinforced side wall that makes continued driving possi-ble to a limited extent despite the tyre losingall or some of its pressure. These tyres are fit-ted on a special rim. (Normal tyres can alsobe fitted to this rim.) If an SST tyre loses tyre pressure then the yellow TPMS lamp in the combined instru-ment panel illuminates and a message isshown in the information display. If thisoccurs, reduce speed to max. 80 km/h. Thetyre must be replaced as soon as possible. Drive carefully, in some cases it can be diffi- cult to see which tyre is faulty. In order toestablish which tyre needs attention, checkall four tyres.
WARNING
Only people with knowledge of SST tyres should fit them. SST tyres must only be fitted together with TPMS. After an error message about low tyre pressure has been shown, do not drivefaster than 80 km/h. Maximum mileage before tyre replacement is 80 km. Avoid hard driving such as sudden braking or turning. SST tyres must be replaced if they are damaged or punctured.

Emergency puncture repair
Emergency puncture repair, where the emer- gency puncture repair kit (TMK - TemporaryMobility Kit) is used to seal a puncture andcheck and adjust the tyre pressure (p. 407). The emergency puncture repair kit (p. 334) consists of a compressor and a bottle of seal-ant. The sealing works as a temporary repair.The sealing fluid bottle must be replacedbefore its expiration date and after use. Thesealing fluid effectively seals tyres puncturedin the tread.
NOTE
The emergency puncture repair kit is only intended for sealing tyres with a puncturein the tread.
The emergency puncture repair kit has limited capacity to seal tyres which have puncturesin the wall. Do not seal tyres with the emer-gency puncture repair kit if they have largerslits, cracks or similar damage. Connect thecompressor to one of the car's 12 V sockets.Choose the socket that is nearest to thepunctured tyre.
IMPORTANT
If the compressor for emergency puncture repair is connected to one of the two sock-ets (p. 141) in the tunnel console then noother current consumer may be connectedto the other one.
NOTE
The compressor for temporary emergency puncture repair has been tested andapproved by Volvo.
