Using RDS
Your audio system is equipped with a Radio Data
System (RDS). RDS is a system that sends data along
with the audio of the FM station you are currently tuned
to. You can use RDS to display program information
and to control your radio. With RDS, the radio can:

Seek only to stations with the types of programs
you want to listen to,

seek to stations with traffic announcements,

receive announcements concerning local and
national emergencies, and

receive and display messages from radio stations.
RDS is always on. RDS features are only available for
use on FM stations which broadcast RDS information.
The RDS features of your radio rely upon receiving
specific RDS information from these stations. These
features will only work when the RDS information
is available.

3-35
In rare cases, a radio station may broadcast incorrect
information that will cause the radio features to work
improperly. If this happens, please contact the
radio station.
When you are tuned to an RDS station, the station name
will appear on the display, instead of the frequency.
Most RDS stations provide their station name, the time
of day and a Program Type (PTY) for their current
programming. Some stations also provide the name
of the current program.
DISP: Press this knob to change what appears on the
display while using RDS. The display options are station
name, station frequency, PTY and the name of the
program (if available). Press and hold the display knob
to set the default display of the RDS station from the
displays available.
Accessing RDS Stations:
1. Push the SEEK TYPE button or turn the P
-TYPE
LIST/AUDIO knob to display the program type list.
2. Turn knob either clockwise or counterclockwise to
select a program type. List is alphabetical. If you
select ANY TYPE your radio will seek to the first
PTY available.
3. Push SEEK TYPE button to activate search.TRAF: Press this button to receive traffic
announcements. If the current tuned station does not
broadcast traffic announcements, the radio will seek to
a station that does. The TRAF icon will flash on the
display. When the radio finds a station that broadcasts
traffic announcements, it will stop. If no station is found,
NO TRAF will appear on the display.
Traffic Interrupt Feature: Your radio can be
programmed to interrupt the playback of a cassette tape,
CD or FM radio by enabling the traffic interrupt feature.
Press the TRAF button once to seek to an RDS station
that supports the traffic interrupt feature if the current
tuned station does not. The TRAF icon will flash on the
display when seeking for a station that supports traffic
interrupt. When the traffic interrupt feature is on, TRAF
will appear on the display.
When a traffic announcement comes on the tuned radio
station, you will hear it, even if the volume is muted or
a cassette tape or compact disc is playing. The TRAF
icon and TRAFFIC will appear on the display while
the traffic announcement plays. If the cassette tape or
compact disc player was being used, the tape or compact
disc will stay in the player and resume play at the point
where it stopped.

VOL: Turn this knob clockwise to increase volume when
RDS interrupts regular play. Turn it counterclockwise to
decrease volume.
INFO: If the current station has a message, INFO will
appear on the display. These text messages are from the
RDS broadcaster to the listening public and may be
general information such as artist and song title, call in
phone numbers, etc. Press this button to see the
message. If the whole message does not appear on
the display, parts of the message will appear every
three seconds until the message is completed. To scroll
through the message at your own speed press the INFO
button again for less than one second. A new group
of words will appear on the display. Once the complete
message has been displayed, INFO will disappear from
the display until another new message is received. The
old message can be displayed by pressing the INFO
button until a new message is received or a different
station is tuned to.P-TYPE LIST: Turn this knob clockwise or
counterclockwise to select the Program Type (PTY) you
want to listen to. TYPE and a PTY will appear on the
display. Press the SEEK TYPE button and the radio
will seek to the first RDS broadcaster of the selected
P
-TYPE. If the radio cannot find the desired P-TYPE,
NONE will appear on the display and the radio will
return to the last station you were listening to.
SEEK TYPE: Press this button to go to a station with
the last selected PTY. TYPE and the last selected PTY
will appear on the display, if it is not already showing.
Press SEEK TYPE a second time to seek. If a station
with the selected PTY is not found, the radio will return
to the original station and display NONE.
ALERT!: This type of announcement warns of national
or local emergencies. You will not be able to turn off alert
announcements. ALERT! appears on the display when an
alert announcement plays. When an alert announcement
comes on the tuned radio station, you will hear it, even if
the volume is muted or a cassette tape or compact disc
is playing. If the cassette tape or compact disc player is
playing, play will stop for the announcement and resume
when the announcement is finished.
This function will only work during actual emergency
broadcasts, and will not work during tests of the
emergency broadcast system. This feature is not
supported by all RDS stations.

and the radio will beep once. The radio will not
automatically switch to other stations when AF is off.
Playing a Cassette Tape
Your tape player is built to work best with tapes that are
up to 30 to 45 minutes long on each side. Tapes longer
than that are so thin they may not work well in this
player. The longer side with the tape visible should face
to the right. If the ignition is on, but the radio is off,
the tape can be inserted and will begin playing. A tape
symbol is shown on the display whenever a tape is
inserted. If you hear nothing but a garbled sound, the
tape may not be in squarely. Press EJT to remove the
tape and start over.
While the tape is playing, use the VOL, FADE, BAL,
TREB, BASS and SEEK controls just as you do
for the radio. The display will show TAPE and an
arrow showing which side of the tape is playing.If you want to insert a tape when the ignition is off,
first press EJT or DISP.
If CHK TAPE appears on the radio display, the tape
won't play because of an error.
CHK TAPE may be displayed when the tape is tight and
the player can't turn the tape hubs. Remove the tape.
Hold the tape with the open end down and try to turn
the right hub counterclockwise with a pencil. Turn the
tape over and repeat. If the hubs do not turn easily,
your tape may be damaged and should not be used in
the player. Try a new tape to make sure your player is
working properly.
CHK TAPE may be displayed when the tape is broken.
Try a new tape.
CHK TAPE may be displayed when the tape is wrapped
around the tape head. Attempt to get the cassette out.

3-44 Care of Your Cassette Tape Player
A tape player that is not cleaned regularly can cause
reduced sound quality, ruined cassettes or a damaged
mechanism. Cassette tapes should be stored in their
cases away from contaminants, direct sunlight and
extreme heat. If they aren't, they may not operate
properly or may cause failure of the tape player.
Your tape player should be cleaned regularly after every
50 hours of use. Your radio may display CLEAN
to indicate that you have used your tape player for
50 hours without resetting the tape clean timer. If this
message appears on the display, your cassette tape
player needs to be cleaned. It will still play tapes, but
you should clean it as soon as possible to prevent
damage to your tapes and player. If you notice a
reduction in sound quality, try a known good cassette
to see if it is the tape or the tape player at fault. If this
other cassette has no improvement in sound quality,
clean the tape player.The recommended cleaning method for your
cassette tape player is the use of a scrubbing action,
non-abrasive cleaning cassette with pads which scrub
the tape head as the hubs of the cleaner cassette turn.
The recommended cleaning cassette is available through
your dealer (GM Part No. 12344789).
When using a scrubbing action, non
-abrasive cleaning
cassette, it is normal for the cassette to eject because
your unit is equipped with a cut tape detection feature
and a cleaning cassette may appear as a broken tape.
To prevent the cleaning cassette from being ejected,
use the following steps.
If your vehicle is equipped with the AM FM Stereo with
Cassette Tape Player:
1. Turn the ignition to ON or ACC.
2. Turn the radio off.
3. Press and hold the TAPE AUX button for
five seconds. READY will appear on the display
and a cassette icon will flash for five seconds.
4. Insert the scrubbing action cleaning cassette.
5. Eject the cleaning cassette after the manufacturer's
recommended cleaning time.
