Installing a wheel
It is important to install wheels properly.
1. Clean the contact surfaces on the wheel andhub.
2.Lift the wheel and place it on the hub.
3. Install the wheel bolts and tighten hand-tight.Using the lug wrench, tighten crosswise untilall bolts are snug.
4.Lower the vehicle to the ground and alter-nately tighten the bolts crosswise to103 ft. lbs. (140 Nm).
5. Press the plastic covers onto the wheel bolts.

CAUTION
•After inflating the tires, always reinstallthe valve cap to help avoid damage to thevalve from dirt, gravel, etc.
•Use plastic valve caps only. Metal capscould corrode and become difficult toremove.

Tire Pressure Monitoring System(TPMS)
TPMS provides a warning if inflation pressure inone or more tires is too low. It also uses a sym-bol (called a telltale) that will flash for60 seconds and then glow steadily if there is asystem malfunction.
TPMS uses the rotational speed of the tires incombination with signal analysis of the ABS sen-sor signals to determine if they are properly infla-ted. When a tire is under-inflated, its diameter(and consequently also its rotational speed)changes. By comparing the individual tires witheach other it is possible to determine if one ormore tires are under inflated. If inflation pressureis too low, an indicator symbol will illuminate inthe instrument panel and a text message will bedisplayed.
SymbolExplanation
The symbol illuminates to indicatelow tire inflation pressure.
If a malfunction occurs in the sys-tem, the tire pressure warning sym-bol will flash for approximately1 minute and then remain illumi-nated.
Each tire, including the spare (if provided), shouldbe checked monthly when cold and inflated to

the inflation pressure recommended by the vehi-cle manufacturer on the vehicle placard or tireinflation pressure label. (If your vehicle has tiresof a different size than the size indicated on thevehicle placard or tire inflation pressure label, youshould determine the proper tire inflation pres-sure for those tires.)
As an added safety feature, your vehicle hasbeen equipped with a tire pressure monitoringsystem (TPMS) that illuminates a low tire pres-sure telltale when one or more of your tires issignificantly under-inflated. Accordingly, when thelow tire pressure telltale illuminates, you shouldstop and check your tires as soon as possible,and inflate them to the proper pressure.
Driving on a significantly under-inflated tire cau-ses the tire to overheat and can lead to tire fail-ure. Under-inflation also reduces fuel efficiencyand tire tread life, and may affect the vehicle'shandling and stopping ability. Please note thatthe TPMS is not a substitute for proper tire main-tenance, and it is the driver's responsibility tomaintain correct tire pressure, even if under-infla-tion has not reached the level to trigger illumina-tion of the TPMS low tire pressure telltale.
Your vehicle has also been equipped with aTPMS malfunction indicator to indicate when thesystem is not operating properly. The TPMS mal-function indicator is combined with the low tirepressure telltale.
When the system detects a malfunction, the tell-tale will flash for approximately one minute andthen remain continuously illuminated. Thissequence will continue upon subsequent vehiclestart-ups as long as the malfunction exists. Whenthe malfunction indicator is illuminated, the sys-tem may not be able to detect or signal low tirepressure 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
When the TPMS symbol illuminates, the followingtext messages may also be displayed:
•Tire pressure low
•Tire pressure system Temporarilyunavailable
•Tire pressure system Service required
If TPMS cannot determine which tire(s) have lowinflation pressure:
•All four tires will be shown as affected in thecenter display
After changing wheels, always calibrate the sys-tem to avoid false warnings.
TPMS does not replace the need for regular tireinspection and maintenance.
NOTE
If you change to tires with a different dimen-sion than the factory-installed ones, theTPMS system must be calibrated for thesetires.
TPMS cannot be turned off.

WARNING
Incorrect inflation pressure could lead to tirefailure, resulting in a loss of control of thevehicle.

Reinflating tires equipped with theTire Pressure Monitoring System(TPMS)
When low tire pressure has been detected, amessage will be displayed in the instrumentpanel and the Tire Pressure Monitoring Systemsymbol will illuminate.
SymbolExplanation
When the TPMS symbol illuminatesand a message is displayed, check,reinflate the tire(s) and calibrateTPMS.
1. Use a tire pressure gauge to check the infla-tion pressure of all four tires.
2.Re-inflate the tire(s) to the correct pressure.Consult the tire pressure decal located onthe driver's side B-pillar (the structural mem-ber at the side of the vehicle, at the rear ofthe driver's door opening) or the inflationpressure table in your printed owner's man-ual supplement.
3. Calibrate the Tire Pressure MonitoringSystem, see the article "Calibrating the TirePressure Monitoring System".
4. In some cases, it may be necessary to drivethe vehicle for several minutes at a speed ofat least 20 mph (30 km/h) to erase theTPMS telltale warning and the text message.Please be aware that the TPMS telltalewarning will not go out until the low tire pres-sure has been corrected and calibration hasbeen carried out.

NOTE
To help avoid incorrect tire inflation pressure,if possible only inflate the tires when they arecold. The tires are considered to be coldwhen they have the same temperature as thesurrounding (ambient) air. This temperature isnormally reached after the vehicle has beenparked for at least 3 hours. After driving a dis-tance of approximately 1 mile (1.6 km), thetires are considered to be warm.

CAUTION
When inflating tires, press the pump's mouth-piece straight onto the valve to help avoidbending or otherwise damaging the valve.
CAUTION
•After inflating the tires, always reinstallthe valve cap to help avoid damage to thevalve from dirt, gravel, etc.
•Use plastic valve caps only. Metal capscould corrode and become difficult toremove.

WARNING
•Incorrect inflation pressure could lead totire failure, resulting in a loss of control ofthe vehicle.
•Tire monitoring systems cannot indicatesudden tire damage caused by externalfactors (e.g., a blowout) in advance.

Calibrating the Tire PressureMonitoring System (TPMS)
In order for the Tire Pressure Monitoring Systemto work properly, tire pressure reference valuesmust be set correctly. This must be done eachtime wheels are changed or tire pressures aremodified.

Calibrating TPMS
To calibrate the system:
1. Switch off the engine.
2. Re-inflate the tire(s) to the correct pressure.Consult the tire pressure decal located onthe driver's side B-pillar (the structural mem-ber at the side of the vehicle, at the rear ofthe driver's door opening) or the inflationpressure table in your printed owner's man-ual supplement.
3. Start the engine.
4.Open the Car status app in the center dis-play's App view.
5.Tap Status to access Tire PressureMonitoring System.
6.Tap the calibration button.
7.Tap OK after the tire pressure in all four tireshas been checked and adjusted.
8.Drive the vehicle.
> The calibration process will be completedwhile driving and will be interrupted if thevehicle is parked and the engine isswitched off. Calibration continues auto-matically when driving resumes.
When enough data has been collected to detecta low tire pressure situation, the tires' color in thecenter display will change to green. The systemwill not give any text confirmation when calibra-tion is finished although it will state if calibrationfails. When driving with heavy loads or at sus-tained highway speeds, the tire pressure shouldbe adjusted to the recommended inflation pres-sures.
After adjusting inflation pressure, repeat steps1-8.
NOTE
Always remember to calibrate the Tire Pres-sure Monitoring System when the wheelshave been changed or the tire inflation pres-sure has been corrected according to the tirepressure decal or tire inflation pressure table.
If correct reference values have not been set,the system cannot issue low tire pressurealerts correctly.
The vehicle must be parked with the enginerunning to access the calibration button andto start the calibration process.

WARNING
The exhaust gases contain carbon monoxide,which is invisible and odorless but very poi-sonous. For this reason, always perform thecalibration procedure outdoors or in a work-shop with exhaust gas evacuation equipment.

Emission inspection readiness
How do states use OBD II for emission
inspections?
Many states connect a computer directly to avehicle'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 inspectionfor 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 waslit 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 maintenance
Periodic maintenance requirements and intervalsare described in your vehicle's Warranty andService Records Information booklet.
The following points can be carried out betweenthe 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. Inspectthe 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, toreduce 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 atthe base of the windshield, and from other placeswhere they may collect.
