CD Player Messages
CHECK DISC:If this message
displays and/or the CD ejects, it
could be for one of the following
reasons:
.It is very hot. When the
temperature returns to normal,
the CD should play.
.The road is very rough. When
the road becomes smoother, the
CD should play.
.The CD is dirty, scratched, wet,
or upside down.
.The air is very humid. If so, wait
about an hour and try again.
.There was a problem while
burning the CD.
.The label is caught in the CD
player.
If the CD is not playing correctly, for
any other reason, try a known
good CD.
If any error occurs repeatedly or if
an error cannot be corrected,
contact your dealer. If the radio displays an error message, write it
down and provide it to your dealer
when reporting the problem.
CD/DVD Player
Care of the CD and DVD Player
Do not add any label to a disc.
It could get caught in the CD or
DVD player. If a disc is recorded on
a personal computer and a
description label is needed, try
labeling the top of the recorded disc
with a marking pen.
The use of CD/DVD lens cleaners is
not advised, due to the risk of
contaminating the lens of the optics
with lubricants internal to the CD
and DVD player mechanism.
Notice:
If a label is added to a
CD, 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

Black plate (24,1)GMC Sierra Owner Manual - 2013 - crc - 8/14/12
7-24 Infotainment System
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.
