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 longitudinal treadgrooves. The letters TWI (Tread Wear Indicator)are visible on the side of the tire. When approxi-mately 1.6 mm (1/16 inch) is left on the tread,the tread will be at the same height as the treadwear indicator. Replace the tire as soon as possi-ble. Tires with low tread offer very poor traction inrain or snow.

Tire terminology The following is a glossary of tire-related terms.
The tire suppliers may have additional markings, notes or warnings such as standard load, radialtubeless, etc.
• Tire information placard
: A placard show-
ing the OE (Original Equipment) tire sizes,recommended inflation pressure, and themaximum weight the vehicle can carry.
• Tire Identification Number (TIN)
: A number
on the sidewall of each tire providing infor-mation about the tire brand and manufactur-ing plant, tire size and date of manufacture.
• 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 maximum load at 35psi [37 psi (2.5 bar) for Metric tires]. Increas-ing the inflation pressure beyond this pres-sure will not increase the tires load carryingcapability.
• 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 pressure.
• 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 which the tirebeads are seated.
• Maximum load rating
: a figure indicating
the maximum load in pounds and kilogramsthat can be carried by the tire. This rating isestablished by the tire manufacturer.
• Maximum permissible inflation pressure
:
the greatest amount of air pressure thatshould ever be put in the tire. This limit is setby 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 inflationplacard(s) located on the driver's side B-pillarand in the tire inflation table in this chapter.
• Cold tires
: The tires are considered to be
cold when they have the same temperatureas the surrounding (ambient) air. This tem-

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).

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.

CAUTION
Snow chains can be used on the vehicle, with the following restrictions:• Volvo recommends not using snowchains on wheel dimensions larger than19 inches.
• Always follow the manufacturer's installa-tion instructions carefully. Install chainsas tightly as possible and retighten peri-odically.
• Only put snow chains on the front wheels(also applies to all-wheel drive vehicles).
• If accessory, aftermarket or "custom"tires and wheels with different dimen-sions than the original tires and wheelsare used, snow chains in some casesmay NOT be used. Sufficient distancebetween the chains and brakes, suspen-sion and body components must bemaintained.
• Check local regulations regarding the useof snow chains before installing.
• Never exceed the snow chain manufac-turer's specified maximum speed limit.Under no circumstances should youexceed 50 km/h (30 mph).
• Avoid bumps, holes or sharp turns whendriving with snow chains.
• Avoid driving on surfaces without snow as this wears out both the snow chains andthe tires.
• The handling of the vehicle can beadversely affected when driving withchains. Avoid fast or sharp turns as wellas locked wheel braking.
• Some types of strap-on chains affectbrake components and therefore mustNOT be used.
Consult a Volvo retailer for more information about snow chains.

Tire sealing system12
The temporary tire sealing system can be used to seal a puncture in a tire or to check andadjust the pressure in the tire. Models equipped with a spare wheel 13
do not
have the tire sealing system.
The tire sealing system consists of a compressor and a bottle containing sealing compound. Thesealing functions as a temporary repair.
NOTE
The sealing compound effectively seals tires with punctures in the tread but may not beable to fully seal tires with punctures in thesidewall. Do not use the tire sealing systemon tires with large tears, cracks or similardamage.
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 cargo compartment.

MAINTENANCE AND SERVICE

Emission inspection readiness
How do states use OBD II for emission
inspections?
Many states connect a computer directly to a vehicle's OBD II system. The inspector can thenread "faults." In some states, this type of inspec-tion has replaced the tailpipe emission test.
How can my vehicle fail OBD II emission
inspection?
Your vehicle can fail OBD II emission inspection for any of the following reasons:
• If your Check Engine (MIL) light is lit, yourvehicle may fail inspection.
• If your vehicle's Check Engine light was lit,but went out without any action on your part,OBD II will still have a recorded fault. Yourvehicle may pass or fail, depending on theinspection practices in your area.
• If you had recent service that required dis-connecting the battery, OBD II diagnosticinformation may be incomplete and "notready" for inspection. A vehicle that is notready may fail inspection.
How can I prepare for my next OBD II
emission inspection?
• If your Check Engine (MIL) light is lit - or was lit but went out without service, have your vehicle diagnosed and, if necessary, servicedby a qualified Volvo technician.
• If you recently had service for a lit CheckEngine light, or if you had service thatrequired disconnecting the battery, a periodof driving is necessary to bring the OBD IIsystem to "ready" for inspection. Two half-hour trips of mixed stop-and-go/highwaydriving are typically needed to allow OBD II toreach readiness. Your Volvo retailer can pro-vide you with more information on planning atrip.
• Maintain your vehicle in accordance with yourvehicle's maintenance schedule.
Owner maintenancePeriodic maintenance requirements and intervalsare described in your vehicle's Warranty andService Records Information booklet. The following points can be carried out between the normally scheduled maintenance services.
Each time the car is refueled:
•Check the engine oil level.
• Clean the windshield, windshield wipers, headlights, and taillights.
Monthly:
• Check cold tire pressure in all tires. Inspect the tires for wear.
• Check that engine coolant and other fluidlevels are between the indicated "min" and"max" markings.
• Clean interior glass surfaces with a glasscleaner and soft paper towels.
• Wipe driver information displays with a softcloth.
• Visually inspect battery terminals for corro-sion. Corrosion may indicate a loose terminalconnector, or a battery near the end of itsuseful service life. Consult your Volvo retailerfor additional information.
As needed:
Wash the car, including the undercarriage, to reduce wear that can be caused by a buildup ofdirt, and corrosion that can be caused by salt res-idues. Clean leaves and twigs from air intake vents at the base of the windshield, and from other placeswhere they may collect.
