SAFETY
64ries for both the infant or child and other occu- pants in the vehicle. When a child has outgrown the child safety seat, you should use the rear seat with thestandard seat belt fastened. The best way tohelp protect the child here is to place the childon a cushion so that the seat belt is properlylocated on the hips. Legislation in your state orprovince may mandate the use of a child seator cushion in combination with the seat belt,depending on the child's age and/or size.Please check local regulations. A specially designed and tested booster cush- ion and backrest can be obtained from yourVolvo retailer. See also the article "Integratedbooster cushion."
WARNING

Do not use child safety seats or child booster cushions/backrests in the frontpassenger's seat. We also recommendthat children under 140 cm (4 feet7 inches) in height who have outgrownthese devices sit in the rear seat withthe seat belt fastened.
Sedan models: Keep vehicle doors andtrunk locked and keep remote controlsout of a child's reach. Unsupervisedchildren could lock themselves in anopen trunk and risk injury. Childrenshould be taught not to play in vehi-cles.
On hot days, the temperature in thevehicle interior can rise very quickly.Exposure to these high temperaturesfor even a short period of time cancause heat-related injury or death.Small children are particularly at risk.Never leave children unattended in avehicle.
Child seats should always be registered.
Volvo's recommendationsWhy does Volvo believe that no child shouldsit in the front seat of a vehicle? It's quite sim-ple really. A front airbag is a very powerful device designed, by law, to help protect anadult. Because of the size of the airbag and its speed of inflation, a child should never be placed inthe front seat, even if he or she is properly bel-ted or strapped into a child safety seat. Volvohas been an innovator in the field of safetysince it was founded. And we have no inten-tion of resting on our laurels. But we needyour help. Please remember to put your chil-dren in the back seat, and buckle them up.
WARNING
A child restraint should never be reused if:
The vehicle has been involved in a colli- sion, no matter how minor
Its history is unknown
It is older than the manufacturer's expi-ration date

Tread wear indicatorThe tread wear indicator shows the status of the tire's tread.
The tread wear indicator is a narrow elevated strip running across the tire's longitudinaltread grooves. The letters TWI (Tread WearIndicator) are visible on the side of the tire.When approximately 1.6 mm (1/16 inch) is lefton the tread, the tread will be at the sameheight as the tread wear indicator. Replace thetire as soon as possible. Tires with low treadoffer very poor traction in rain or snow.

Tire terminology
The following is a glossary of tire-related terms.
The tire suppliers may have additional mark- ings, notes or warnings such as standard load,radial tubeless, etc.
Tire information placard
: A placard
showing the OE (Original Equipment) tiresizes, recommended inflation pressure,and the maximum weight the vehicle cancarry.
Tire Identification Number (TIN)
: A num-
ber on the sidewall of each tire providinginformation about the tire brand and man-ufacturing plant, tire size and date of man-ufacture.
Inflation pressure
: A measure of the
amount of air in a tire.
Standard load
: A class of P-metric or
Metric tires designed to carry a maximumload at 35 psi [37 psi (2.5 bar) for Metrictires]. Increasing the inflation pressurebeyond this pressure will not increase thetires load carrying capability.
Extra load
: A class of P-metric or Metric
tires designed to carry a heavier maximumload at 41 psi [43 psi (2.9 bar) for Metrictires]. Increasing the inflation pressurebeyond this pressure will not increase thetire's load carrying capability.
kPa
: Kilopascal, a metric unit of air pres-
sure.
PSI
: Pounds per square inch, a standard
unit of air pressure.
B-pillar
: The structural member at the
side of the vehicle behind the front door.
Bead area of the tire
: Area of the tire next
to the rim.
Sidewall of the tire
: Area between the
bead area and the tread.
Tread area of the tire
: Area of the perime-
ter of the tire that contacts the road whenmounted on the vehicle.
Rim
: The metal support (wheel) for a tire
or a tire and tube assembly upon whichthe tire beads are seated.
Maximum load rating
: a figure indicating
the maximum load in pounds and kilo-grams that can be carried by the tire. Thisrating is established by the tire manufac-turer.
Maximum permissible inflationpressure
: the greatest amount of air pres-
sure that should ever be put in the tire.This limit is set by the tire manufacturer.
Recommended tire inflation pressure
:
inflation pressure, established by Volvo,which is based on the type of tires that aremounted on a vehicle at the factory. Thisinformation can be found on the tire infla-

Tire sidewall designations
The following information can be found on a tire's sidewall.
Federal law mandates that tire manufacturers place standardized information on the sidewallof all tires (see the illustration). The vehicle has been certified with certain combinations of wheels and tires. The following information is listed on the tire sidewall: The tire designation:
NOTE
Please be aware that the following tire designation is an example only and that
this particular tire may not be available onyour vehicle.
1. 215: The width of the tire (in millimeters)
from sidewall edge to sidewall edge. The larger the number, the wider the tire.
2. 65: The ratio of the tire's height to its
width in percent.
3. R: Radial tire (the designation RF and the
symbol indicate that the vehicle is
equipped with optional self-supporting run flat tires 3
.
4. 15: The diameter of the wheel rim (in
inches).
5. 95: The tire's load index. In this example, a
load index of 95 equals a maximum load of 1521 lbs (690 kg).
6. H: The tire's speed rating, or the maximum
speed at which the tire is designed to bedriven for extended periods of time, carry-ing a permissible load for the vehicle, andwith correct inflation pressure. For exam-ple, H indicates a speed rating of210 km/h (130 mph).

Snow tires
Snow tires are designed for winter driving conditions.
Volvo recommends snow tires with specific dimensions. The tire dimensions vary depend-ing on engine type. When driving with snowtires, the correct type of tires must be moun-ted on all four wheels.
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 whichside they were mounted on, e.g. L for left and
R for right.
Studded tiresStudded tires should be broken in by driving500–1000 km (300–600 miles) slowly andgently to help the studs settle properly in thetires. This gives the tire, and especially thestuds, a longer service life.
NOTE
Regulations regarding the use of studded tires vary from country to country.
Tread depthRoad conditions with ice, slush and low tem- peratures place considerably higher demandson tires than summer conditions. Volvo there-fore recommends not driving on snow tiresthat have a tread depth of less than 4 mm(0.15 inch).

Tire sealing system14
The temporary tire sealing system can be used to seal a puncture in a tire or to checkand adjust the pressure in the tire. Models equipped with a spare wheel 15
do not
have the tire sealing system.
WARNING
California Proposition 65 Operating, servicing and maintaining a pas- senger vehicle can expose you to chemi-cals including engine exhaust, carbon mon-oxide, phthalates, and lead, which areknown to the State of California to causecancer and birth defects or other reproduc-tive harm. To minimize exposure, avoidbreathing exhaust, do not idle the engineexcept as necessary, service your vehicle ina well ventilated area and wear gloves orwash your hands frequently when servicingyour vehicle. For more information go towww.P65Warnings.ca.gov/passenger-vehicle.
The tire sealing system consists of a compres- sor and a bottle containing sealing compound.The sealing functions as a temporary repair.
NOTE
The sealing compound effectively seals tires with punctures in the tread but maynot be able to fully seal tires with punctu-res in the sidewall. Do not use the tire seal-ing system on tires with large tears, cracksor similar damage.
NOTE
The compressor is intended for temporary tire sealing and is approved by Volvo.
LocationThe tire sealing system is located in a foam block under the floor of the trunk.
Sealing compound expiration dateThe sealing compound bottle must be replaced if its expiration date has passed (seethe decal on the bottle). Handle the old bottleas hazardous waste.

16. Check the inflation pressure on the air
pressure gauge.
If the pressure is under 1.3 bar (19 psi), the tire is not sufficiently sealed. Thevehicle should not be driven. Call road-side assistance to have the vehicletowed.
If the inflation pressure is higher than1.3 bar (19 psi), the tire must be inflatedto the inflation pressure specified onthe tire pressure decal on the driver'sside door pillar (1 bar = 100 kPa =14.5 psi). If the inflation pressure is toohigh, use the air release valve to releaseair.
WARNING
Check inflation pressure regularly.
Volvo recommends driving to the nearest authorized Volvo workshop to have the tirereplaced/repaired. Inform the workshop thatthe tire contains sealing compound. The sealing compound bottle and the hose must be replaced after use. Volvo recom-mends contacting an authorized Volvo work-shop for replacement.
WARNING
After using the tire sealing system, the vehicle should not be driven farther thanapproximately 200 km (120 miles).
NOTE
The compressor is an electric device. Fol- low local regulations for disposal.
