Roof-Mounted Lamp
If the vehicle has this feature, this
button includes wiring provisions for
a dealer or a qualified service center
to install an auxiliary roof lamp.
This button is located on the
overhead console.
When the wiring is connected to
an auxiliary roof‐mounted lamp,
pressing the bottom of the buttonwill activate the lamp and illuminate
an indicator light at the bottom of
this button. Pressing the top of the
button will turn off the roof‐mounted
lamp and indicator.
The emergency roof lamp circuit
is fused at 30 amps, so the total
current draw of the attached lamps
should be less than this value.
The attachment points for the roof
lamp circuits are two blunt cut
wires located above the overhead
console, a dark green switched
power wire and a black ground wire.
For more information on roof mount
emergency lamp installation, please
visit the GM Upfitter website at
www.gmupfitter.com or contact your
dealer.

Notice:If a label is added to
a CD, or more than one CD is
inserted into the slot at a time,
or an attempt is made to play
scratched or damaged CDs, the
CD player could be damaged.
While using the CD player, use
only CDs in good condition
without any label, load one CD at
a time, and keep the CD player
and the loading slot free of
foreign materials, liquids, and
debris.
If an error displays, see “CD
Messages” later in this section.Care of CDs and DVDs
If playing a CD-R or CD-RW, the
sound quality can be reduced due to
CD-R or CD-RW quality, the method
of recording, the quality of the music
that has been recorded, and the
way the CD-R or CD-RW has been
handled. Handle them carefully.
Store CD-Rs or CD-RWs in their
original cases or other protective
cases and away from direct sunlight
and dust. The CD or DVD player
scans the bottom surface of the
disc. If the surface of a disc is
damaged, such as cracked, broken,
or scratched, the disc does not play
properly or not at all. Do not touch
the bottom side of a disc while
handling it; this could damage the
surface. Pick up discs by grasping
the outer edges or the edge of the
hole and the outer edge. If the surface of a disc is soiled,
clean it with a soft, lint‐free cloth or
dampen a clean, soft cloth in a mild,
neutral detergent solution mixed
with water. Make sure the wiping
process starts from the center to
the edge.

through the speakers at one time.
An audio source is defined as DVD
slot, CD slot, XM, FM‐AM, front
auxiliary jack, USB port, or rear
auxiliary jack.
