Playing an MP3/WMA
With the ignition on, insert a CD partway into the slot,
label side up. The player will pull it in, Loading, then
Filecheck, and then MP3 or WMA will appear on the
display. The CD should begin playing. You cannot insert
a CD with the ACC off.
As each new track starts to play, the track number, and
the song name will appear on the display.
If the ignition or radio is turned off with a CD in the player,
it will stay 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 will start playback. When the ignition and
radio are turned on, the CD will start 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 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 3-75 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.
If an error appears on the display, 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.

button for longer than two seconds. The song title or

only when the SOUND button is pressed for longer
