The LCD unit is the digital display area. A frame placed over the LCD unit visually separates it into six display areas for the indicator and warning lamps. A special feature here is that holes had to be drilled through the LC display for the connection of each pointer instrument (speedometer and tachometer).

In order to ensure that the LC display can also be read easily at low temperatures, the display is heated. The heating consists of heating wires on a sheet behind the display. When the driver's door is opened, the switch-on signal is sent by the CAS via the K-CAN System bus to the instrument cluster.

The display heating is activated at temperatures below 10°C (50°F).
