Chevrolet 2007 Avalanche Owner's Manual page 323

If playing a CD-R, the sound quality may be
reduced due to CD-R quality, the method of
recording, the quality of the music that has been
recorded, and the way the CD-R has been
handled. There may be an increase in skipping,
difficulty in finding tracks, and/or difficulty in loading
and ejecting. If these problems occur, check the
bottom surface of the CD. If the surface of the CD
is damaged, such as cracked, broken, or
scratched, the CD will not play properly. If the
surface of the CD is soiled, see Care of Your CDs
and DVDs on page 352 for more information.
If there is no apparent damage, try a known
good CD.
Notice: If you add any label to a CD, insert
more than one CD into the slot at a time,
or attempt to play scratched or damaged CDs,
you could damage the CD player. When
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.
Do not add any label to a CD. It could get caught
in the CD player. If a CD is recorded on a
personal computer and a description label is
needed, try labeling the top of the recorded CD
with a soft marker instead.
If an error appears on the display, see "CD
Messages" later in this section.
CD (Eject): Press and release the CD eject
Z
button to eject the CD-R that is currently
playing in the bottom slot. You will hear a beep
and Ejecting Disc will be displayed. Once the disc
is ejected, Remove Disc will appear on display.
The CD-R can be removed. If the CD-R is
not removed, after several seconds, the CD-R will
be automatically pulled back into the player.
If loading and reading of a CD cannot be
completed, such as unknown format, etc., and the
disc fails to eject, press and hold the DVD eject
button for more than five seconds to force the disc
to eject.
