GMC 2007 Sierra - Manual (Page 131)

Swing-Out Windows
Your vehicle may have
swing-out windows. To
open a rear swing-out
window, flip the
latch open and swing
the glass out.
The latch will catch when the window is fully open
and it will also hold it in the open position.
Sliding Rear Window
If your vehicle has this feature, squeeze the latch
in the center of the window and slide the glass
to open it.
When you close the window, be sure the latch is
engaged.
The sliding rear window does not have rear
defogger.
Sun Visors
Pull the sun visor down to block glare. Swing the
sun visor to the side to cover the side window.
The passenger’s side sun visor may have a vanity
mirror.
Theft-Deterrent Systems
Vehicle theft is big business, especially in some
cities. Although your vehicle has a number of
theft-deterrent features, we know that nothing we
put on it can make it impossible to steal.
Content Theft-Deterrent
Your vehicle may have a content theft-deterrent
alarm system.
The security light,
located on the
instrument panel cluster,
will flash as you open
the door, while the
ignition is off, to indicate
the system is being
activated.
