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.

1. Activate the vehicle's hazard warning flashersif the tire sealing system is to be used in anarea with traffic.
If the flat tire was caused by a nail, etc., donot remove it from the tire. It will help to sealthe hole.
2.Peel off the speed limit sticker and affix it tothe windshield so that it is clearly visible tothe driver. The vehicle should not be drivenfaster than 50 mph (80 km/h) while using atire that has been temporarily repaired withthe tire sealing system.
3.Ensure that the on/off switch is in position 0and take out the electrical wire and hose.

NOTE
Do not break the seal on the bottle. Thisoccurs automatically when the bottle isscrewed into the holder.

WARNING
Contact with the sealing compound maycause skin irritation. If contact occurs, washthe affected area immediately with soap andwater.
4.Unscrew the orange cover over the bottleholder on the compressor and unscrew thecap on the bottle of sealing compound.
5. Screw the bottle into the bottle holder as faras possible.

WARNING
The bottle is equipped with a catch to keep itsecurely in place and help prevent sealingcompound leakage. Once in place, the bottlecannot be unscrewed. This must be done by atrained and qualified Volvo service technician.

14. Immediately drive the vehicle for approxi-mately 2 miles (3 km) at a maximum speedof 50 mph (80 km/h) to distribute the seal-ing compound in the tire. During the tire'sfirst revolution, some sealing compound mayspray out of the puncture hole.

WARNING
No one should stand closer to the vehiclethan approx. 7 ft (2 m) when it drives away tohelp avoid being sprayed with sealing com-pound.

CAUTION
If your vehicle is equipped with the Tire Pres-sure Monitoring System (TPMS), the use ofthe sealing compound may lead to incorrecttire pressure readings or in rare cases, dam-age to the tire pressure sensor. Use the tiresealing system to check and adjust the dam-aged tire's inflation pressure.

NOTE
•Safely stow the tire sealing system in aconvenient place as it will soon be usedagain to check the tire

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.

CAUTION
The compressor should not be used for morethan 10 minutes at a time to avoid overheat-ing.
5. Inflate the tire to the correct pressure (seethe tire pressure decal on the on the driver'sside B-pillar (the structural member at theside of the vehicle, at the rear of the driver'sdoor opening). Use the air release valve torelease some air from the tire if necessary.
6. Turn off the compressor (press the on/offswitch to position 0) when the correct infla-tion pressure has been reached.

CAUTION
•After inflating the tires, always reinstall thevalve cap to help avoid damage to thevalve from dirt, gravel, etc.
•Use plastic valve caps only. Metal capscould corrode and become difficult toremove.
7. Disconnect the electrical wire from the 12-volt socket.
