Interior Lighting

Interior Lighting












As with previous Systems, the control of the interior lights is a function of the general module. New features of the interior lighting circuit are:

The addition of warning lights in the edge of the doors. These red lights are controlled by each door contact and illuminate when the doors are opened.

- The design of the interior light switch has changed. It is now a push button switch. Pushing the button will carry out the opposite command of the current status of the lights. (i.e.: if the interior lights are currently on, pushing the button will switch the lights off.)
- If the interior lights are switched "ON" by the button with the ignition on, the interior lights will remain on until they are switched off by the button.
- If the interior lights are switched "ON" when the ignition is switched off, the lights will remain on for 16 minutes.
- Locking the vehicle from the outside will immediately switch off the interior lights.
- Pressing the interior light button for longer than three seconds will switch the lights to continuous off. This feature is intended for workshop use. Pressing the button again will return the lights to the normal operational status.







Illuminated Transmission Shift Indicator







The E38 uses a microprocessor for displaying the shifter position in the center console. The processor receives shift position signals from a console mounted range switch. The processor illuminates the LED corresponding to the position of the range selector.

The LED will remain on after KL 15 is turned off and stay on until ZKE goes into the sleep mode.

Since the LED is supplied power by the consumer cut out function it is part of part of the interior lighting circuit. If the LED fails to illuminate, always consider the consumer cutout function of the GM III.
