Saving a new reference value for tyre pressure monitoring*
In order for the system for tyre pressure monitoring1 to work correctly, a reference value for the tyre pressure must be saved. This must take place every time the tyres are changed or the tyre pressure is changed so that the system can warn about low pressure correctly.
For example, when driving with a heavy load or at high speed above 160 km/h (100 mph), the tyre pressure should be adjusted in accordance with Volvo's recommended tyre pressure values. The system is then reset by saving a new tyre pressure.
Perform the following procedure to store a new tyre pressure as a reference value in the system:
Switch off the car.
Inflate the tyres to the correct pressure, see the decal on the door pillar on the driver's side showing the recommended pressure for factory fitted tyres.
Start the car.
Press 
in the centre display.
in the centre display.Press Car status.
Press Store pressure.
If storing fails, a message is shown.
