WHEELS AND TIRES
468When 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 of reasons, 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 following text messages may also be displayed:
•
Tire pressure low
•Tire pressure system Temporarily
unavailable
•Tire pressure system Service required
If TPMS cannot determine which tire(s) have low inflation 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 tire inspection 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 tire failure, resulting in a loss of control of thevehicle.

Explanation
When the TPMS symbol illuminates and 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 on the 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 Monitoring System, see the article "Calibrating the TirePressure Monitoring System".

4704. In some cases, it may be necessary to drive
the vehicle for several minutes at a speed of at 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 reinstall the 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 to tire 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 Pressure Monitoring System (TPMS)
In order for the Tire Pressure Monitoring System to work properly, tire pressure reference valuesmust be set correctly. This must be done eachtime wheels are changed or tire pressures aremodified.
Calibrating TPMSTo calibrate the system:
1. Switch off the engine.
2. Re-inflate the tire(s) to the correct pressure. Consult the tire pressure decal located on the 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 Pressure
Monitoring System.

6. Tap the calibration button. 7.
Tap
OK after the tire pressure in all four tires
has been checked and adjusted.
8. Drive the vehicle. > The calibration process will be completedwhile driving and will be interrupted if the vehicle 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 steps 1-8.
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 engine running 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.

WARNING
If heavy vibrations, unsteady steering behavior, or noises should occur while driving, reducespeed and park the vehicle in a safe place.Recheck the tire for bumps, cracks, or othervisible damage, and recheck its inflation pres-sure. If the pressure is below 19 psi (1.3 bar),do not continue driving. Have the vehicletowed to a trained and qualified Volvo servicetechnician.
15. Rechecking the pressure Reconnect the tire sealing system's hose to the tire's inflation valve. 16. Without starting the compressor, check the
inflation pressure on the air pressure gauge. •If the pressure is under 19 psi (1.3 bar), the puncture has not been sealed suffi-ciently and the vehicle should not bedriven. Have the vehicle towed to a trainedand qualified Volvo service technician.
• If the pressure is more than 19 psi(1.3 bar), connect the electrical wire to a12-volt socket, start the compressor andinflate the tire to the correct pressure(see the tire pressure decal on the on thedriver's side B-pillar (the structural mem-ber at the side of the vehicle, at the rearof the driver's door opening). Use the airrelease valve to release some air from thetire if necessary.

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.
