Tires are perishable goods. After a few years, they will begin to harden and their frictionproperties will gradually deteriorate. Alwaysreplace tires with the freshest tires possible.This is particularly important for snow tires. Aseries of numbers is imprinted on the sidewallof the tire. The last four digits in the series isthe Department of Transportation (DOT)stamp and indicates the week and year thetire was manufactured. The tire in the illustra-tion has 0717 as the last four digits, whichmeans it was manufactured week 7 of 2017.
Tire ageTires degrade over time, even when they arenot being used. It is recommended that tiresgenerally be replaced after 6 years of normalservice. Heat caused by hot climates, frequenthigh loading conditions or Ultra Violet (U.V.)exposure can accelerate the aging process. The temporary spare
2
should also be replaced
at 6-year intervals, even if it has never been used. A tire with e.g., visible cracks or discol-oration should be replaced immediately.
Tire economy
Maintain correct tire pressure.
Avoid fast starts, hard braking and tirescreeching.
Tire wear increases with speed.
Correct front wheel alignment is veryimportant.
Unbalanced wheels impair tire economyand driving comfort.
Tires must maintain the same direction ofrotation throughout their lifetime.
When replacing tires, the tires with themost tread should be mounted on the rearwheels to reduce the chance of oversteerduring hard braking.
Hitting curbs or potholes can damage thetires and/or wheels permanently.
Tire rotationYour vehicle has no required tire rotation. Driv-ing style, tire pressure, climate and road con-ditions affect how quickly the tires age andexhibit signs of wear. Maintaining the correcttire pressure helps keep tread wear evenly dis-tributed. To help prevent differences in tread depth and wear patterns forming on the tires, the frontand rear wheels should be rotated, i.e. thefront tires moved to the rear and the rear tiresmoved to the front. Ideally, tire rotation shouldbe done the first time after approximately5000 km (ca 3100 miles) and thereafter at10,000 km (approx. 6200 miles) intervals. If you have any questions regarding tread depth, Volvo recommends consulting an authorized Volvo workshop. If significant dif-ferences in wear (> 1 mm difference in treaddepth) between the tires have already occur-red, the least worn tires should always bemounted on the rear wheels. A front-wheelskid (understeer) is usually easier to controlthan a rear-wheel skid (oversteer). If the frontwheels skid, the vehicle will continue in astraight line instead of the rear wheels skid-ding to the side, which could cause you tocompletely lose control of the vehicle. It istherefore important that the rear wheels neverlose grip before the front wheels.
Storing wheels and tiresWhen storing complete wheels (tires mountedon rims), they should be suspended off thefloor or placed on their sides on the floor. Tires not mounted on rims should be stored on their sides or standing upright, but should notbe suspended.
CAUTION
Tires should preferably be stored in a cool, dry, dark place, and should never be storedin close proximity to solvents, gasoline,oils, etc.

Tire direction of rotation Tires with tread designed to roll in only one direction are marked with an arrow on thesidewall.
The arrow shows the tire's direction of rotation.
The tire should maintain the same direc- tion of rotation throughout its service life.
Tires should only be moved between thefront and back, never from right to left orvice versa.
Incorrectly mounted tires impair the vehi-cle's braking properties and ability to forceaside rain, snow and slush.
The tires with the most tread shouldalways be mounted on the rear wheels tohelp reduce the risk of skidding.
NOTE
Use tires of the same type, dimensions and make (manufacturer) on each axle.

Checking tire pressure
Correct inflation pressure helps improve driv- ing stability, save fuel and increase the serv-ice life of the tires.
Tire pressure decreases over time, which is normal. Tire pressure also varies depending onthe ambient temperature. Driving on under-inflated tires could cause the vehicle to over-heat and lead to damage. Tire pressure affectstraveling comfort, road noise and driving cha-racteristics. Check the pressure in the tires every month. Use the recommended inflation pressure forcold tires to help maintain good tire perform-ance. Under-inflated or over-inflated tirescould cause uneven tread wear. Use an air pressure gauge and check the infla- tion pressure on all the tires, including the spare tire 4
, at least once a month and before
long trips. Volvo recommends buying a relia- ble air pressure gauge, as the automaticgauges provided at service stations may beinaccurate.
WARNING
Under-inflation is the most common cause of tire failure and may result insevere tire cracking, tread separation,or "blow-out," with unexpected loss ofvehicle control and increased risk ofinjury.
Under-inflated tires reduce the loadcarrying capacity of your vehicle.
Cold tiresInflation pressure should be checked when thetires are cold. The tires are considered to becold when they have the same temperature asthe surrounding (ambient) air. This tempera-ture is normally reached after the vehicle hasbeen parked for at least 3 hours. After driving for approximately 1.6 km (1 mile), the tires are considered to be warm. If youneed to drive longer than that to inflate thetires, check and record the inflation pressureof the tires first and inflate accordingly whenyou arrive at the pump. When the ambient temperature changes, so does the inflation pressure. A 10-degree tem-perature drop causes a corresponding drop ininflation pressure of 1 psi (7 kPa). Check theinflation pressure of the tires regularly andadjust to the correct pressure, which can be found on the vehicle's tire information decal orcertification label. If you check inflation pressure when the tires are warm, you should never release air. Thetires become warm after driving and it is nor-mal for warm tires to have an inflation pres-sure above the recommended pressure forcold tires. A warm tire with an inflation pres-sure equal to or under the recommended pres-sure for cold tires could be significantly under-inflated.Related information

Changing a wheel
Wheel changes must always be carried out correctly. The following instructions showhow to remove and install a wheel and whatis important to keep in mind. Make sure thatthe tire dimension is approved for use on thevehicle.
WARNING
If a tire must be changed near passing traffic, make sure all passengers moveto a safe location.
Use a jack intended for the vehiclewhen changing a tire. For any otherjob, use stands to support the vehicle.
Never crawl under or allow any part ofyour body to be extended under a vehi-cle supported by a jack.
Never let anyone remain in the vehiclewhen it is raised on a jack.

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.
Tips for changing snow tiresWhen switching between regular tires andsnow tires, mark the tires according to whichside they were mounted on, e.g. L for left and
R for right.
Contact a Volvo retailer for assistance deter-mining the most suitable rims and tires.
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
Legal requirements concerning the use of studded tires may vary. Always follow locallaws and regulations.
Tread depthRoad conditions with ice, slush and low tem- peratures place considerably higher demands on 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 system17
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 18
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 cargo compartment floor.
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.

Periodic maintenance helps minimize emissions
NOTE
Refer to your Service and Warranty Booklet for a comprehensive serviceand maintenance schedule up to240,000 km (150,000 miles). Thisprogram contains inspections and ser-vices necessary for the proper functionof your vehicle and includes compo-nents that affect vehicle emissions.
The Warranty and Service RecordsInformation booklet also containsdetailed information concerning thewarranties that apply to your vehicle.
On-board Diagnostic SystemOBD II is part of your vehicle's computerized engine management system. It stores diag-nostic information about your vehicle's emis-sion controls. It can light the Check Enginelight (MIL) if it detects an emission control"fault." A "fault" is a component or systemthat is not performing within an expectedrange. A fault may be permanent or temporary.OBD II will store a message about any fault.
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 canthen read "faults." In some states, this type ofinspection has replaced the tailpipe emissiontest.
How can my vehicle fail OBD II emission
inspection?
Your vehicle can fail OBD II emission inspec- tion for any of the following reasons: If your Check Engine (MIL) light is lit, your vehicle may fail inspection.
If your vehicle's Check Engine light was lit,but went out without any action on yourpart, OBD II will still have a recorded fault.Your vehicle may pass or fail, dependingon the inspection 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,serviced by a qualified Volvo technician.
If you recently had service for a lit CheckEngine light, or if you had service thatrequired disconnecting the battery, aperiod of driving is necessary to bring theOBD II system to "ready" for inspection.Two half-hour trips of mixed stop-and-go/highway driving are typically needed toallow OBD II to reach readiness. YourVolvo retailer can provide you with moreinformation on planning a trip.
Maintain your vehicle in accordance withyour vehicle's maintenance schedule.
Owner maintenancePeriodic maintenance requirements and inter-vals are described in your vehicle's Warrantyand Service Records Information booklet. The following points can be carried out between the normally scheduled maintenanceservices.
Each time the vehicle is refueled:
Check the engine oil level.
Clean the windshield, windshield wipers, headlights, and taillights.
