Location 

The instrument cluster (A1) is located in the dashboard on the driver-side. Between the instrument cluster and the Audio/COMAND display (A40/8) is the center instrument panel display section (A40/19) which displays the ATA function indicator and the airbag ON/OFF indicator lamps.

Tasks 

The instrument cluster has the following tasks:

Reading in of sensors and signals 

The signals and requests are read in by the instrument cluster via the user interface CAN (CAN HMI) or the combined display section via the instrument panel LIN (LIN 1).

Evaluation of input factors 

The input factors that have been read in are evaluated by the integrated microprocessor and the relevant components are then actuated.

Output of warning tones and indicator tones 

The instrument cluster actuates the instrument cluster speaker (H4/61) in the driver footwell to output warning and indicator tones which are requested by the systems installed in the vehicle.

Output of signals 

The instrument cluster sends information and data over the following connections:

User interface CAN 

The instrument cluster transmits information and data via user interface CAN to various control units.

HSVL 

The instrument cluster is connected to the head unit (A26/17) via a HSVL. Via this interface, the instrument cluster transmits signals to the displays and graphics in the Audio/COMAND display. With code 463 (Head-up display), the instrument cluster is connected to the head-up display (A40/12) via an HSVL line. Via this interface, the instrument cluster sends signals for the displays and graphics to the head-up display.

Variants 

The right and center display areas of the instrument cluster are freely programmable.
