General

The instrument cluster has the following tasks:

Output of the important operating condition of the vehicle
Warning about critical operating conditions of the vehicle
Display unit of various systems
Computer and display for the active service system PLUS (ASSYST PLUS)
Trip computer (RRE) for the driver

Networking and information flow

The instrument cluster receives all information via the central CAN. On vehicles with code (610) night view assist if necessary the night vision can be faded into the multifunction display. For this the instrument cluster has its own low-voltage differential signaling (LVDS) interface. The displays in the instrument cluster can be differentiated into variable displays and fixed displays.

Fixed displays

Fixed displays cannot change their position and are always shown at the same point.

The following displays, warning lamps and indicator lamps are fixed displays:

Coolant temperature display
Fuel level and reserve indicator
Tachograph
Fuel reserve indicator lamp
Coolant temperature warning lamp
Engine diagnosis indicator lamp
Preglow indicator lamp
CHECK ENGINE indicator lamp (A1e26)
High beam headlamp indicator lamp
ABS indicator lamp
Airbag indicator and warning lamp

Some fixed displays in the instrument cluster are only fitted country-specific.

Variable displays

Variable displays can change their position and are shown at various points as required. Some variable displays can also be switched on or off via the various menu levels.

In general all the displays in the multifunction display are variable displays and can change their position.

Some variable displays in the instrument cluster are only shown country-specific in the multifunction display.

Operation of the instrument cluster

The menu levels of the instrument cluster are operated via the following buttons of the multifunction steering wheel (MFL):

Scroll forward/back button (S110s1)
System select button (S110s3)
"Back" and VCS [SBS] off button (S110s4)
