Playing a CD (Single CD Player)
Insert a CD partway into the slot, label side up.
The player pulls it in and the CD should begin
playing.
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 playing
where it stopped, if it was the last selected audio
source.
When a CD is inserted, the CD symbol appears
on the radio display. As each new track starts
to play, the track number displays.
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 can 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 can 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 370for more information.
If there is no apparent damage, try a known
good CD.
Notice:If a label is added to a CD, or 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.
