Saving a new reference value for tire pressure monitoring
The tire pressure monitoring system needs a reference value to work from. This means that the value needs to be updated in certain circumstances for the system to work properly.
Whenever the tire pressure is adjusted, a new reference value needs to be saved. This could be when certain changes are made, such as every time you change to wheels that require a different recommended tire pressure. The reference value may also need to be updated when there is a significant change in the vehicle's weight due to loading or unloading.
Even when you are handling a low tire pressure warning and inflating to the previous reference value, you need to save the tire pressure value again to account for any temperature-related changes.
To save a new reference value, the vehicle needs to be turned on and stationary.
- Inflate the tires to the correct tire pressure.[1]
- Press the vehicle symbol
in the bottom bar and go to Status→Tire pressure. - Press
to get to settings. - Select your reference tire pressure and press Save.
Note
Save button unavailable
For safety reasons, the Save button is only available when the vehicle is turned on and stationary.
The button is also unavailable if there is a warning about very low tire pressure in the instrument panel. This is to avoid accidentally saving a low value as reference. In this case, you need to inflate the tires to correct reference tire pressure and then start driving the vehicle. Once the warning in the instrument panel disappears, you can stop the vehicle and continue with saving a new reference value.
- Confirm that you want to save a new value. The confirmation step helps prevent changing the new reference value by mistake.This overwrites the previous tire pressure and temperature and enters a new reference value.
- Start driving the vehicle at a speed above 30 km/h (20 mph).
