Playing an MP3/WMA
While the ignition is on, insert a CD partway into the
slot, label side up. The player pulls it in, Loading, then
Filecheck, and then MP3 or WMA displays. The CD
should begin playing. A CD plays only while the ignition
is on or ACC (Accessory).
As each new track starts to play, the track number, and
the song name displays.
If the ignition or radio is turned off with a CD in the
player, it stays in the player. When a CD is in the player
and the ignition is turned on, the radio must be turned
on before the CD starts playback. When the ignition and
radio are turned on, the CD starts playing 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 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 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 does not
play properly. If the surface of the CD is soiled, see Care
of Your CDs on page 3-78 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 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.
If an error displays, see "CD Messages" later in this
section.
All of the CD functions work the same while playing an
MP3/WMA, except for those listed here. See "Playing
a CD" earlier for more information.
