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.
Open the Car Status app in the app view.
The car must be stationary for the Store Pressure button to be selectable.
Press Store Pressure.
Tap on OK to confirm that the tyre pressure in all four tyres has been checked and adjusted.
Drive the car until the new tyre pressure has been saved.
The new tyre pressure is stored when the car is driven at a speed above 35 km/h (22 mph).
If the car's ignition is switched off before the new tyre pressure has been saved then the procedure needs to be performed again. Allow the storing to finish within the same driving cycle to ensure that the new tyre pressure has been saved correctly.
If storing fails, a message is shown: Storing pressure unsuccessful. Try again..
The exhaust gases contain carbon monoxide, which is invisible and odourless, but highly toxic. The procedure to save a new tyre pressure must therefore always be performed outdoors or in a workshop with exhaust extraction.
