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.
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 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 on page 3-126 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 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.
