player will pull it in, and READING will appear on
the display. The CD should begin playing. If you want
to insert a CD with the ignition off, rst press the
eject button or the DISPL knob.
If the ignition or radio is turned off with a CD in the
player it will stay in the player. When the ignition or radio
is turned on, the CD will start to play where it stopped,
if it was the last selected audio source.
When the CD is inserted, the CD symbol will appear
on the display. As each new track starts to play,
the track number will appear on the display.
The CD player can play the smaller 3 inch (8 cm) single
CDs with an adapter ring. Full-size CDs and the
smaller CDs are loaded in the same manner.
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 nding 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, seeCare of Your CDs and DVDs on
page 3-129for more information.If there is no apparent damage, try a known good CD.
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 marking pen instead.
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.
