(Dome Lamp Override): You can use the dome
override button, located below the exterior lamps control,
to set the dome and footwell lamps to come on
automatically when a door is opened, or to remain off.
To turn the lamps off, press the button into the in
position. With the button in this position, the dome lamps
will remain off when the doors are open. To return the
lamps to automatic operation, press the button again
and return it to the out position. With the button in this
position, the dome lamps will come on when you
open a door.

New Hummer in MN - 
I added the sunroof, towing package and... thats about it. I looked at all the other options and the base was all I needed. Already had a RTFM moment when I needed to figure out why the cabin lights did not come on when we exit (there is a button that turns this on/off). Thinking the stereo definitely needs to be upgraded and possibly going to add some basic exterior items though I love the looks as is so no rush. Stereo I am sure I will be shooting some questions to Importkiller and some of the other radio guys once i finish abusing the search button.
