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.

The CD player can play the smaller 3 inch (8 cm) single
CDs with an adapter ring. Full-size CDs and the

If playing a CD-R, the sound quality may be reduced

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
