player pulls it in and the CD should begin playing.
If you want to insert a CD with the ignition off, rst
press the eject button or the DISP knob.
If the ignition or radio is turned off with a CD in the
player it stays in the player. When the ignition or
radio is turned on, the CD starts to play where it
stopped, if it was the last selected audio source.
When the CD is inserted, the CD symbol appears
on the display. As each new track starts to
play, the track number appears 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 on page 231
for 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.
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.
If an error appears on the display, see
“CD Messages” later in this section.
