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 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 352for 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

Radio Data System (RDS)
The audio system has a Radio Data System
(RDS). RDS features are available for use only on
FM stations that broadcast RDS information.
With RDS, the radio can do the following:
Seek to stations broadcasting the selected
type of programming
Receive announcements concerning local and
national emergencies
Display messages from radio stations
This system relies upon receiving specic
information from these stations and will only work
when the information is available. In rare cases,
a radio station may broadcast incorrect information
that will cause the radio features to work
improperly. If this happens, contact the radio
station.
While the radio is tuned to an RDS station, the
station name or call letters will appear on the
display instead of the frequency. RDS stations may
also provide the time of day, a program type
(PTY) for current programming, and the name of
the program being broadcast.
