Change the reference value by recalibrating the system, such as for driving with a heavy load, for example.
Always adjust the tyre pressure according to Volvo's recommended tyre pressure values before recalibration.
The car must be stationary when calibration is started.
Settings are made using the centre console's controls, see MY CAR.
Inflate the tyres to the desired pressure in accordance with the tyre pressure label on the driver's side door pillar (between front and rear doors).
Start the engine.
Open the menu system MY CAR.
Select the Tyre pressure menu.
Select Calibrate tyre pressure and press OK.
Drive for at least 10 minutes at a speed of at least 30 km/h(20 mph).
Calibration is performed automatically following initialisation by the driver. The system provides no confirmation when the calibration is complete.
The new reference values apply until steps 1-6 are carried out again.
