Fuel Gauge

There is sensor in the fuel tank, in some cases two. These transmit signals about the actual fuel level to the central electronic module (CEM) (4/56). The central electronic module (CEM) sends the signals on to the driver information module (DIM) (5/1). The driver information module (DIM) receives the signals, interprets them and displays the actual fuel level in the fuel gauge.

The low fuel level warning lamp lights when the fuel level is low. The warning lamp informs the driver that the fuel level is low.

The warning lamp lights when there are less than 9 liters of gasoline depending on the engine type, in the tank.

The fuel gauge is not sensitive to rapid change. This is to prevent incorrect values being displayed when cornering or driving on slopes for example.
