Saving a new reference value for tyre pressure monitoring

The tyre pressure monitoring system needs a reference value to work from. This means that the value needs to be reset in certain circumstances for the system to work properly.

A new reference value needs to be stored when certain changes have been made, such as every time you adjust the tyre pressure or change the tyres. The reference value may also need to be updated when there is a significant change in the car's weight due to loading or unloading.

Turn the car off.
Inflate the tyres to the correct tyre pressure.1
Start the car.
Press the car symbol in the bottom bar and go to Status → Tyre pressure.
Select Update reference pressure.

 Note

The Update reference pressure button is used to store a new reference value for the tyre pressure monitoring system. For safety reasons, it's only available when the car is turned on and stationary.
Confirm that you want to store a new value. The confirmation step is needed to avoid saving a new reference value by mistake.
This overwrites the previous tyre pressure and enters a new reference value.
Start driving the car. The new value will be stored after driving for several minutes at a speed above 35 km/h (22 mph).
  • Once a new reference value is stored, the animation showing the saving progress disappears from the centre display.
  • If storing fails, an error message is shown.
