Switch-on Conditions
The adaptive headlight can be activated as from terminal status "Terminal 15 ON".
The rain/light/solar/condensation sensor sends the request to switch on the low beam headlights as soon as it detects low light levels (darkness). Initially, the footwell module switches on the headlight driver modules. The adaptive headlight is ready for operation following a reference run of the bi-xenon headlights.
NOTE:
A reference run is performed during every new start.
The conditions for switching on the adaptive headlight are:
- "Terminal 15 ON"
- Light switch in automatic driving light control position
- Rain/light/solar/condensation sensor detects darkness
- Both bi-xenon headlights are intact.
NOTE:
The footwell module detects a defective bi-xenon headlight by measuring the intake current of the respective bi-xenon headlight.
