Ambiance Lighting in 2011 X5

[deutsch100]

Included in the Premium Package for the 2011 X5, is what BMW calls "Ambiance Lighting". What is this? In my 2010 750i, the entire cabin at night was bathed in really soothing amber/orange lighting....on the doors, rear seats, storage comparments, footwells, etc...

The first time I drove home in my new '11 X5 at night, I was kind of shocked that the interior cabin is so dark at night. Is "Ambiance Lighting" something that has to be activated, or turned on?

Thanks a lot!
