Instrument Panel Brightness; Dome Lamps - GMC TopKick 2007 Owner's Manual

Instrument Panel Brightness

This feature controls the brightness of the
instrument panel lights.
The thumbwheel for this feature is located to the
right of the exterior lamp control.
Turn the thumbwheel up to brighten the lights.
When the thumbwheel is moved to the first
position, the radio display and transmission
selection display will go to full intensity. The
instrument panel cluster will also be dimly
lit. Moving the thumbwheel up to the next position
will activate the interior dome lamps.

Dome Lamps

The dome lamps will come on when you open
a door.
You can also turn the dome lamps on by moving
the thumbwheel, located to the right of the
exterior lamp control, all the way up to the second
position. In this position, the dome lamps will
remain on whether a door is open or closed.
You can use the dome override button to set the
dome lamps to automatically come on when a
door is open, or to remain off.
The dome override button is located below the
exterior lamp control.
If the dome override button is pushed in, the dome
lamps will not come on. Use this feature when
you want to leave your door(s) open for an
extended period of time and do not want to run
the battery down.
If the dome override button is in the out position,
the interior lamps will work as usual.
