Change the reference value by recalibrating the system, such as for driving with a heavy load, for example.
For high-speed driving (above 160km/h (100 mph)) the tyre pressure should be adjusted in accordance with Volvo's recommended tyre pressure values.
TPMS adjusts the reference value automatically at this speed. For the system to operate correctly, recalibration must not be performed.
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 1-5 are carried out again.
