Saving 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 Polestar'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 PS2-2007-Car symbol in the centre display.
Press More.
Press Car status.
Press Store pressure. The car must be running and stationary when storing a tyre pressure.


The Store pressure button is used to save new reference values for tyre pressures in the tyre pressure monitoring system. For safety reasons, it is only available (selectable) when the car is stationary and the electric motor is running.
The tyre pressure must be saved after adjusting the tyre pressure or changing the tyres. Adjust the tyre pressure to the recommended values and press Confirm to save the tyre pressure.


To avoid mistaken activation of the Store pressure function, it is necessary to confirm in a second step that the tyre pressure should be saved.
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 storage progress for a new reference value disappears from the centre display.

If storing fails, a message is shown.
