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 Volvo-recommended 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:
Switch off the ignition.
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.
Start the vehicle.
Tap in the center display.
Tap Car status.
Tap Store pressure.
If storing cannot be performed, a message will be displayed.
