The map light near the sunglasses holder, they are what I would think should be coming on. There is just an on and off switch. Two up front and 2 in the back seat.
Now down at the bottom left there are 4 buttons, one to pop the trunk, one to change the ambient light color, another is a dimmer for dash lights and the forth I am not really sure what it is, maybe that one is adjusting the darkest of the ambient lights .
thanks for helping me think this through
