Saving a new reference value for tyre pressure monitoring*

In order for the system for tyre pressure monitoringIndirect Tyre Pressure Monitoring System (ITPMS) 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.

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.

Press TPMS.


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).

When sufficient data have been collected for the system to be able to detect low tyre pressure, the animation showing the progress of storing the new reference value disappears from the centre display. The system does not provide additional confirmation that a new tyre pressure has been saved.

If storing fails, a message is shown.


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.
