Rheostat level
| Rheostat level |
| General |
The SID is connected to the rheostat and controls the button lighting in the SID. It is also used to calculate the display lighting level.
The buttons and display are illuminated by LEDs.
When the main lights switch is ON, bus information is sent: RHEOSTAT LEVEL, unit %. The information is used by the ACC, Audio, DICE and MIU to regulate the button and instrument lighting.
Rheostat level 0% is sent if:
| • |
The main lights switch is OFF and fuse 35 for the daylight driving lights is removed.
|
|
| • |
The interior light exceeds a certain level.
|
|
The information is used by the ACC, Audio, DICE and MIU which then extinguishes the button and instrument lighting.
