Function
The interior illumination (IBL) system implements the illumination of the vehicle interior. The master control unit for this is the overhead control panel control unit.
The following control options for switching on/off are available:
- Automatic, when unlocking/locking the vehicle via the central locking system (CL [ZV])
- Automatic, when opening/closing a door
- Automatic, when opening/closing the trunk lid
- Automatic, depending on the position of the rotary light switch
- Manual, when pressing a corresponding switch
With code (551) Anti-theft alarm system (ATA [EDW]) when the anti-theft alarm system (ATA [EDW]) is triggered, the following lamps are switched on immediately without dimming:
- Front dome lamp
- Left rear interior lamp (model 221)
- Right rear interior lamp (model 221)
- Left coat hook lamp (E15/24) (model 216)
- Right coat hook lamp (E15/25) (model 216)
By removing the transmitter key (A8/1) from the EIS [EZS] control unit, the front dome lamp and the rear interior lights are switched on dimmed. They are automatically switched off after the run-on time has elapsed, which can be set via the COMAND controller unit.

Control illumination, function
The switch and controls illumination is activated when
- Rotary light switch is set to "Standing lights"
- Rotary light switch is at position "Automatic" and the rain/light sensor signals "Night"
The brightness of the switch and controls illumination can be adjusted via the switch and controls illumination/Night View Assist display brightness control (S6/2r1) integrated into the cockpit switch group. The brightness control is read in by the upper control panel control unit via the upper control panel LIN. The upper control panel control unit transmits the signal of circuit 58d in steps of 0 to 100% on the interior CAN.
The following control units are supplied with circuit 58d via CAN:
- Via interior CAN
- Front SAM control unit with fuse and relay module
- Rear control unit (N22/6) (model 216)
- AAC [KLA] control unit (N22/1)
- Door control units
- Overhead control panel control unit
- EIS [EZS] control unit
