General
The instrument cluster (A1) serves:
- to provide information on the important operating conditions of the vehicle (e.g. vehicle speed, fuel level etc..),
- to provide a warning in the event of critical operating conditions,
- as a display of the various systems (e.g. audio, trip computer, etc..),
- as a computer and display for the "Active service system" (ASSYST)
- as a trip computer

To do this the instrument cluster (A1) has a multifunction display (A1p13), various display instruments, warning and indicator lamps and an audible transmitter.

In addition various signals (e.g. "vehicle speed, terminal 58d") are generated in the instrument cluster (A1) and passed on to the CAN/engine compartment and to the CAN connection between the instrument cluster (A1) and radio (A2) or between the instrument cluster and the COMMAND operating, display and control module (A40/3). In the function description this CAN bus is abbreviated to CAN (A1-A2, A40/3). The information required is passed on to the instrument cluster (A1) from various control modules via the CAN/engine compartment or discrete lines. The instrument cluster has a microprocessor to process the incoming data. The necessary program and data required are stored in an electronic memory module.

Operations via the system select/voice control pushbutton (S110s3), the scroll forward/back pushbuttons (S110s1) of the multifunction steering wheel and via the three buttons on the instrument cluster (A1).


NOTE: Diagnosis is via the Star diagnosis tool.
