Operation of tyre pressure monitoring system

Activating/deactivating system: The tyre pressure monitoring system is operated via the MMI. – Switch on ignition. – Press function key “CAR”. – Select “Systems” from “CAR” menu. – Select “Tyre pressure monitoring system”. – Select System ON to activate tyre pressure monitoring system or OFF to deactivate system. Note Depending on the software installed, the system cannot be switched off on some vehicles. Function: The tyre pressure monitoring system is operated via the MMI. The system monitors the tyre inflation pressures that have been set by the operator and stored as reference values. – Inflation pressures must be checked, corrected and stored beforehand. – Start by checking and correcting inflation pressure of tyres on vehicle (including spare wheel) according to figures listed on sticker on fuel filler flap. Storing inflation pressures: To ensure reliable operation of the tyre pressure monitoring system, it is important to store the reference pressures correctly. The system will then automatically “learn” the new figures. Proceed as follows: – Switch on ignition. – Press function key “CAR”. – Select “Systems” from “CAR” menu. – Select “Tyre pressure monitoring system”. – Select “Store tyre pressures”. The new tyre pressures must be stored as reference values whenever the inflation pressures are changed intentionally and after every wheel change.
