Playing a Compact Disc

Insert a disc partway into the slot, label side up. The
player will pull it in. The disc should begin playing. The
display will show CD. If you want to insert a compact disc
with the ignition off, first press RCL or the eject button.
The integral CD player can play the smaller 8 cm single
discs with an adapter ring. Full-size compact discs
and the smaller discs 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. You may experience an
increase in skipping, difficulty in finding tracks and/or
difficulty in loading and ejecting. If these problems occur
try a known good CD.
Do not add paper labels to discs, they could get caught
in the CD player.
Do not play 3 inch discs without a standard adapter disc.
If an error appears on the display, see "Compact Disc
Messages" later in this section.
