| The tyre pressure monitoring system monitors the inflation pressure of the tyres on the four road wheels while the vehicle is moving. |
| For safety reasons, the tyre pressure sensors must be renewed if they are defective. |
| Do not use steam cleaners or a powerful jet of compressed air to clean the tyre pressure sensors. |
| For safety reasons, the tyre pressure sensor must be renewed and the wheel rim must be cleaned if tyre sealing compound has been used. |
| The tyre pressure monitoring system consists of a control unit, a central aerial integrated in the control unit and a tyre pressure sensor in each wheel. |
| If the wheels are changed or rotated to a different position on the vehicle, if the tyre pressure sensors are renewed, or if the tyre pressures are altered, the new status must always be confirmed by storing the pressures in the control unit. |
Note | After changing wheels with tyre pressure sensors, for instance from summer to winter tyres, the tyre pressures must be checked and the sensors re-adapted to the control unit. |
| A fault may be detected and registered in the event memory: |
| If there is a system malfunction. |
| If fewer than four wheels are fitted with tyre pressure sensors. |
| If the wrong type of tyre pressure sensor is fitted on winter tyres, or if winter tyres without tyre pressure sensors are fitted. (In this case the yellow warning lamp with „system malfunction“ pictogram will light up in the instrument cluster; this cannot be deactivated via the system.) |
| If the system has detected new sensors, but the tyre pressure monitor button -E226- has not been pressed in order to confirm the current inflation pressures. (In this case the system fault is cancelled when the button is pressed.) |
