General 

Ambient lighting enables the atmosphere in the vehicle interior to be adapted through corresponding lighting. To do so, it illuminates different areas of the vehicle interior directly or indirectly.

Depending on the model, the ambient lighting is controlled by the ambient lighting control unit or the signal acquisition and actuation module. The LEDs installed for the ambient lighting can be actuated in up to 64 different colors.

Anti-theft alarm system (ATA [EDW])

Function requirements 

• Circuit 30t
• No overvoltage or undervoltage
• Ambient lighting switched on through the multimedia system

Function 

Ambiance illumination 

The ambient lighting switches on after the following events:

• Unlocking of vehicle (except via the emergency key)
• Circuit 15R ON

The ambient lighting switches off after the following events:

• 10 s after locking the vehicle (dimmed)
