GF82.20-P-2026Q Lamp Dimming, Function

The front dome lamp (N70e1) integrated in the overhead control panel control unit (N70) and rear dome lamp (E15/3) are switched on and off dimmed with both manual and automatic interior light actuation.
The switch-on time and switch-off time of the lamps is 1 second in each case.
The lamps are switched off automatically in accordance with the "interior light" OFF delay time adjusted in the instrument cluster (A1); the provision for adjustment of the OFF delay time is from 0 to 20 seconds in a 5 second cycle.

On vehicles with anti-theft alarm system (ATA) (code 551a) the lamps are switched on immediately without dimming. In the event of undervoltage or overvoltage the lamps are switched off immediately without dimming. When the correct voltage is restored, the lamps are switched on without dimming.
The "dimming" described here only relates to the switch-on and switch-off characteristics. It must not be confused with dimming the switch and controls illumination via circuit 58d.
