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
Seek to stations with traffic announcements
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.

player will pull it in, and READING will appear on
the display. The CD should begin playing. If you want to
insert a CD with the ignition off, rst press the eject
button or the DISPL knob.
If the ignition or radio is turned off with a CD in the
player it will stay in the player. When the ignition or radio
is turned on, the CD will start to play where it stopped,
if it was the last selected audio source.
When the CD is inserted, the CD symbol will appear on
the display. As each new track starts to play, the
track number will appear on the display.
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 3-142for 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.
