Using RDS
Your audio system is equipped with Radio Data Systems
(RDS). RDS mode gives you many useful new features.
With RDS the radio can do the following:

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,

receive and display messages from radio stations and

search for a stronger station when a station is too
weak for listening.
RDS features are only available for use on FM stations
which broadcast RDS information.
(RDS Select): Press this button to use the
alternate RDS functions (RDS, TA, MSG, PTY and
the PTY arrows).HR (Hour) or MN (Minute): Press the RDS select
button, followed by one of these buttons to display the
time of the current station. STATION TIME IS will be
displayed. If a time has not been sent to the radio,
NO STATION TIME will be displayed. If you have
recently tuned to the station, you may need to wait a
minute before the time is available to the radio. To set
the clock to the current displayed station time, press and
hold HR or MN until TIME UPDATED is displayed.
There is a two second delay before the time is updated.
RDS does not have to be on to use this function,
but you must be tuned to an FM RDS station.
REGION: Press the RDS select button, then press
and hold the RDS pushbutton for two seconds.
REGION: ON will appear on the display. When an
RDS station becomes weak, this function searches for
a stronger station within the same network. A network
can span a great distance. One network can have stations
spread across a country or continent. Each network
breaks down into regions. With regions, local news
items like weather and traffic are available to you.
When the region function is on, the radio only searches
for stations in the same network and region. You can
only use the region function when RDS is on. Press the
RDS pushbutton again to turn the region function off.
REGION: OFF will appear on the display.

PTY name may be the same or different. Press BAND
to recall the frequency and PTY displays. If the radio
is tuned to a station that is not broadcasting RDS
information, the station's frequency will remain on the
display. While RDS is on, the radio will search for a
stronger station in the network when a station gets too
weak for listening.

two seconds, the PTY you set will return.
5. Repeat the steps for each pushbutton.
When battery power is removed and later applied,
you will not have to reset your RDS presets because
the radio remembers them.RDS Messages
ALERT: This type of announcement warns of national
or local emergencies. You will not be able to turn off

TA VOLUME will appear on the display while the
volume is being adjusted. When an alert announcement
comes on the current radio station or a related network
station, you will hear it, even if the volume is muted
or a cassette tape or compact disc is playing. If the
radio tunes to a related network station for an alert
announcement, it will return to the original station

announcements, the radio will seek to a station
which does.
When the radio finds a station which broadcasts traffic
announcements, it will stop. If no station is found,
NONE FOUND will appear on the display and the TA
symbol will turn off. When the SEEK or SCAN buttons
are pressed with the TA function on, the radio will only
stop at stations which broadcast traffic announcements.

special type of volume called TA volume. To increase
TA volume, turn the VOL knob clockwise. Turn it
counterclockwise to decrease volume. TA VOLUME
will appear on the display while the volume is
being adjusted.When a traffic announcement comes on the current
radio station or a related network station, you will
hear it, even if the volume is muted or a cassette tape or
compact disc is playing. If the radio tunes to a related
network station for a traffic announcement, it will
return to the original station when the announcement is
finished. 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.

A new group of words will appear on the display.
Once the complete message has been displayed,
MSG will disappear from the display until another
new message is received.

The cassette tape is tight and the cassette player
cannot turn the hubs of the tape. Hold the cassette
tape with the open end down and try turning the
right hub counterclockwise with a pencil. Flip the
tape over and repeat. If the hubs do not turn easily,

tape is broken. Try a new tape.)

3-31 Radio Personalization with Home and
Away Feature (If Equipped)
If DRIVER 1 (HOME or AWAY) PRESETS or
DRIVER 2 (HOME or AWAY) PRESETS appears
in the display when the radio is first turned on,
your vehicle is equipped with this feature.
This feature allows the driver to return to the last used
audio source (radio, cassette or CD) using their remote
keyless entry transmitter. This feature can also store
and recall AM and FM presets, volume, tone and the
last selected radio station. The number on the back of
each transmitter (1 or 2) corresponds to driver 1 or 2.
If transmitter 1 is used to enter the vehicle, the last
used audio source and/or settings set by driver 1 will be
recalled. If transmitter 2 is used to enter the vehicle, the
last used audio source and/or settings set by driver 2 will
be recalled. The settings can also be recalled by pressing
the MEMORY seat buttons 1 or 2 located on the
driver's door.
Your radio can store home and away presets. Home and
away presets allow you to use one set of preset radio
settings in the area where you live, and another set when
you go out of town. That way, you will not need to
reprogram your presets every time you travel. With the
radio off and the clock displayed, use fast forward andreverse to select home or away presets. To select the
away presets, press and hold FF for five seconds until
you hear a beep. The next time the radio comes on,
the away presets will be active. To select the home
presets, press and hold RW or REV for five seconds
until you hear a beep. The next time the radio comes on,
the home presets will be active.
When battery power is removed and later applied, you
will not have to reset your home radio presets because
the radio remembers them. However, you will have to
reset your away radio presets.
Theft-Deterrent Feature
THEFTLOCK
is designed to discourage theft of
your radio. Your vehicle has a ªbuilt
-inº theft-deterrent
feature on each radio that is automatic
-- there is
no programming required. The radio in your vehicle
cannot be used in any other vehicle. When the radio
was originally installed in your vehicle at the factory,
it stored the Vehicle Identification Number (VIN).
Each time the ignition is turned on, the VIN is verified.
If the vehicle's VIN does not match the VIN stored in
the radio, THEFTLOCK will be activated and the audio
system will not play. If the radio is removed from your
vehicle, the original VIN in the radio can be used to
trace the radio back to your vehicle.
