How to Reset the Tire Pressure Light (TPMS) on a Volvo S90 Twin Engine

1. Switch off the ignition.
2. Inflate each tire to the correct pressure shown on the tire pressure placard on the driver's side B pillar.
3. Start the vehicle, open the Car Status app in App view, and tap TPMS.
4. With the vehicle stationary, tap Store Pressure, then tap OK to confirm all four tires are checked and adjusted.
5. Drive above 35 km/h (22 mph) until the new pressure is saved and the progress animation disappears.

• Do this each time tires are changed or inflation pressure is adjusted.
• If the ignition is switched off before saving finishes, the procedure must be repeated.
• Perform the procedure outdoors or where exhaust gas is extracted, because exhaust contains carbon monoxide.
