Volvo XC90: Wheels and tires / Saving new reference values for tire inflation pressure monitoring

In order for the tire inflation pressure monitoring system¹ to function correctly, inflation pressure reference values must be saved correctly. To help ensure that the system can correctly alert the driver of low inflation pressure, this must be done each time the tires are changed or the inflation pressure is adjusted.

For example, when driving with a heavy load or at high speeds (over 160 km/h (100 mph)), tire pressure should be adjusted to the Volvorecommended tire pressure values. The system should then be reset by saving the new inflation pressure.

To store the new inflation pressure as a reference value in the system:

1. Switch off the ignition.
2. Inflate the tire to the correct inflation pressure; see the tire pressure placard on the driver's side B pillar for recommended pressures for factory-mounted tires.
3. Start the vehicle.
4. Open the Car Status app in App view.
5. Tap TPMS.

   NOTE

   The vehicle must be stationary for the Store Pressure button to be selectable.

6. Tap Store Pressure.
7. Tap OK to confirm that the tire pressure in all four tires has been checked and adjusted.
8. Drive the vehicle until the new inflation pressure has been saved. The new inflation pressure is stored when the vehicle is driven at speeds over 35 km/h (22 mph). > When enough data has been collected for the system to detect low inflation pressure, the animation showing the progress of the storing procedure will disappear from the center display. The system will not provide any further confirmation that the new inflation pressure has been stored.

If storing cannot be performed, Storing pressure unsuccessful. Try again. will be displayed.

WARNING

The exhaust gases contain carbon monoxide, which is invisible and odorless but very poisonous. The procedure for saving a new inflation pressure must therefore always be performed outdoors or in a workshop with exhaust gas extraction.
