Function
The interior illumination system implements the illumination of the vehicle interior. The master control unit for this is the SAM control unit.

The following operations are possible
^ Switching on and off manually
^ Switching on automatically
^ Automatic switch off

Switching on and off manually
^ by operating the interior lamp switch

Switching on automatically
^ when unlocking the vehicle via the transmitter key
^ when opening the driver or front passenger door
^ when opening the top rear-end door (with model 451.3)
^ when opening the bottom rear-end door (with model 451.4)
^ when an alarm is triggered (with code (V01) Anti-theft alarm system (FFO))

The interior lamp is only automatically switched on if the interior lamp switch has been pushed towards the rear.

Automatically switched on when the vehicle is unlocked using the transmitter key
The "unlock central locking system" request from the transmitter key is read in by the SAM control unit. This then actuates the interior lamp.

Automatically switched on when a door is opened
The opening of the driver or front passenger side door is detected by the relevant rotary tumbler switch. The SAM control unit reads in the rotary tumbler switch signals and then actuates the interior lamp.

Automatically switched on when the rear-end door is opened
The opening of the rear-end door is detected by the rear-end door handle switch (with model 451.4) or the trunk lid rotary tumbler microswitch (with model 451.3). The SAM control unit reads in the signals and then actuates the interior lamp.

Automatically switched off after a door has been opened
^ immediately if circuit 15 on
^ after 15 s when the door is closed and circuit 15 is off
^ after 10 min if the door is open

Automatically switched off after locking/unlocking using the transmitter key
^ if circuit 15 is on
^ 12 s after locking
^ 30 s after unlocking if the doors remain closed
