Applies to: vehicles with tyre pressure monitoring system
To enable the tyre pressure monitoring system to work reliably, it is important to store the correct pressure settings.
You should always store the tyre pressures if new sensors are fitted or after changing the pressures when carrying a different amount of passengers or luggage.
Before storing the new tyre pressures, check that the current pressures on all four wheels correspond to the specified values and adapt the pressures to the current load Fig. ►. Only adjust and store the inflation pressure of the tyres when they are at approximately ambient temperature. If the tyre temperatures are higher than the ambient temperature, the inflation pressures should be increased by approx. 0.2 bar above the pressures specified on the tyre pressure sticker.
Switch on the ignition.
Select the following on the infotainment system: MENU button > Servicing & checks > Tyre pressure loss indicator > Store tyre pressures > Yes, store now. The tyre pressure monitoring system will then measure the current tyre pressures when you drive the vehicle and store them as the new reference values.
If the new tyre pressures do not appear on the infotainment display, you will need to drive for about 10 minutes so that the sensor signal from the wheels can be received again.
During this initialisation phase, --.-- will be shown on the pressure and temperature display and some functions of the tyre pressure monitoring system will not be available. The system will warn you only if the pressure of one or more tyres is below the minimum reference pressure.
If the indicator lamp
lights up and the message Tyre pressure: wheel change detected. Please check all tyres and store pressures in MMI appears, the system has detected that the sensor positions have changed because of a wheel change or that new sensors have been fitted. Store the new tyre pressures.
