In certain cases, it may be necessary to recalibrate TPMS to conform to Volvo's recommended tire inflation pressures (see the inflation pressure table on page 291), for example, if higher inflation pressure is necessary when transporting heavy loads, etc.

This is done in the vehicle's menu system (see page 134).

To recalibrate:

1. Switch off the engine.

2. Inflate the tires to the desired pressure and put the ignition in mode I or II (see page 82 for additional information).

3. Press the MY CAR key in the center console control panel and select Settings Car settings Tire pressure.

4. Press OK/MENU, select Calibrate tire pressure and press OK/MENU again.

5. Drive the vehicle at a speed above 25 mph (40 km/h) continuously for at least 1 minute.

> When the calibration message is no longer displayed, TPMS has been recalibrated to the new inflation pressure.
