Welcome Light
The welcome light can not be activated when the light switch is in position "0" or "1". Furthermore, the side lights are also not to be activated.
The welcome light is switched on as soon as the vehicle is unlocked. For this purpose, the Car Access System makes available the status of the central locking system via the K-CAN2.
The footwell module receives the "Unlock vehicle" status and switches on the exterior lighting for approximately 20 seconds.
While switched on, the welcome light can be deactivated with the "Terminal 15 ON" status.
The following light units are activated:
- Tail lights
