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, and
receive and display messages from radio stations.

Radio Calibration
Your audio system has been calibrated for your vehicle
from the factory. If CALIBRATE appears on the display
it means that your radio has not been configured
properly for your vehicle and must be returned to the
dealership for service.
Personal Choice Radio Controls
(If Equipped)
With this feature, your vehicle will recall the latest radio
settings as adjusted the last time your vehicle was
operated. This feature allows two different drivers to
store and recall their own radio settings for AM and FM
presets, last tuned station, volume, tone and audio
source (radio, cassette or CD). The settings recalled by
the radio are determined by which transmitter was used
to enter the vehicle. After the UNLOCK button is
pressed on the transmitter and the ignition is in ON, the
radio settings will automatically adjust to where they
were last set by the identified driver. All vehicles are
shipped with this feature on. This feature can be
disabled by your dealer if desired.
Theft-Deterrent Feature Non-RDS Radios
(If Equipped)
THEFTLOCK is designed to discourage theft of your
radio. The feature works automatically by learning a
portion of the Vehicle Identification Number (VIN).
If the radio is moved to a different vehicle, it will not
operate and LOC will be displayed.
With THEFTLOCK activated, your radio will not
operate if stolen.
Theft-Deterrent Feature RDS Radios
(If Equipped)
THEFTLOCK is designed to discourage theft of your
radio. The feature works automatically by learning a
portion of the Vehicle Identification Number (VIN).
If the radio is moved to a different vehicle, it will not
operate and LOCKED will be displayed.
When the radio and vehicle are turned off, the blinking
red light indicates that THEFTLOCK is armed.
With THEFTLOCK activated, your radio will not
operate if stolen.

3-32 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 CLN or
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 broken 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 button for five seconds.
CAS will flash on the display for five seconds.
4. Insert the scrubbing action cleaning cassette.
5. Eject the cleaning cassette after the manufacturer's
recommended cleaning time.

3-34 Care of Your Compact Discs
Handle discs carefully. Store them in their original cases
or other protective cases and away from direct sunlight
and dust. If the surface of a disc is soiled, dampen a
clean, soft cloth in a mild, neutral detergent solution and
clean it, wiping from the center to the edge.
Be sure never to touch the side without writing when
handling discs. Pick up discs by grasping the outer edges
or the edge of the hole and the outer edge.
Care of Your Compact Disc Player
The use of CD lens cleaner discs is not advised, due to
the risk of contaminating the lens of the CD optics with
lubricants internal to the CD mechanism.
Fixed Mast Antenna
The fixed mast antenna can withstand most car washes
without being damaged. If the mast should ever become
slightly bent, you can straighten it out by hand. If the
mast is badly bent, as it might be by vandals, you should
replace it.
Check every once in a while to be sure the mast is still
tightened to the fender. If tightening is required, tighten
by hand, then with a wrench one quarter turn.
Chime Level Adjustment
The volume level of the vehicle's chime can be
controlled by the radio. To change the volume level,
press and hold pushbutton 6 with the ignition in ON and
the radio power off. The chime volume level will change
from the normal level to loud, and LOUD will be
displayed on the radio. To change back to the default or
normal setting, press and hold pushbutton 6 again. The
chime level will change from the loud level to normal,
and NORMAL will be displayed.
