Cassette Tape Messages
If an error message appears on the display, it could be
for one of the following reasons:
TIGHT TAPE:The tape is tight and the player
cannot 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.
BROKEN TAPE:The tape is broken. Try a
new tape.
CLEAN PLAYER:If this message appears on the
display, the 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 the tapes and player.

The CD player can play the smaller 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. You may experience an
increase in skipping, difficulty in nding tracks, and/or
difficulty in loading and ejecting. If these problems occur
try a known good CD.
Do not add paper labels to CDs, they could get caught

Theft-Deterrent Feature
THEFTLOCK®is designed to discourage theft of your
vehicle’s radio. It works by using a secret code to
disable all radio functions whenever battery power is
removed and the radio is placed in a different vehicle.
This feature requires no user input to be activated.
The radio is automatically armed when it is put into the
vehicle for the rst time.
When the ignition is turned off, the blinking red light
indicates that THEFTLOCK
®is armed.
If THEFTLOCK
®is activated, the radio will not operate
if stolen. The radio will display LOCKED and a red
LED indicator light will come on above the key symbol
to indicate a locked condition. If this occurs, the radio will
need to be returned to your GM dealer.
Audio Steering Wheel Controls
If your vehicle has this feature, some audio functions
can be adjusted at the steering wheel. They include
the following:
QSEEKR:Press the up or the down arrow to go to
the next or to the previous radio station. The radio
will only seek stations with a strong signal that are in
the selected band.
When a cassette tape or CD is playing, press the
up or the down arrow to go to the next or the
previous selection.
3-63

SCAN:Press this button until SCAN appears on the
display. The radio will go to the rst preset station on the
pushbuttons, play for a few seconds, then go to the
next preset station. Press SCAN again to stop scanning.
The radio will only scan preset stations with a strong
signal that are in the selected band.
AM FM:Press this button to switch between FM1,
FM2, or AM.
When a cassette tape or CD is playing, press this
button to listen to the radio. The inactive tape or CD will
remain safely inside the radio for future listening.
SRCE (Source):Press this button to play a cassette
tape or CD when listening to the radio.
MUTE:Press this button to silence the audio system.
Press it again to turn on the sound.
QVOLR(Volume):Press the up or the down arrow
to increase or to decrease the volume.
Radio Reception
AM
The range for most AM stations is greater than for FM,
especially at night. The longer range, however, can
cause stations to interfere with each other. AM can pick
up noise from things like storms and power lines.
Try reducing the treble to reduce this noise.
FM
FM stereo will give you the best sound, but FM signals
will reach only about 10 to 40 miles (16 to 65 km).
Tall buildings or hills can interfere with FM signals,
causing the sound to come and go.

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 are not, they may not operate
properly or they may cause failure of the tape player.
The tape player should be cleaned regularly after every
50 hours of use. The radio may display CLEAN
PLAYER to indicate that the tape player has been used
for 50 hours without resetting the tape clean timer.
If this message appears on the display, the cassette
tape player needs to be cleaned. It will still play tapes,
but it should be cleaned as soon as possible to
prevent damage to the tapes and player. If there is a
reduction in sound quality, try a known good cassette to
see if the tape or the tape player is at fault. If this
other cassette has no improvement in sound quality,
clean the tape player.
For best results, use 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.The cut tape detection feature of the cassette tape
player may identify the cleaning cassette tape as
a damaged tape, in error. If the cleaning cassette ejects,
insert the cassette at least three times to ensure
thorough cleaning.
A non-scrubbing action, wet-type cleaner which uses a
cassette with a fabric belt to clean the tape head
can be used. This type of cleaning cassette will not
eject on its own. A non-scrubbing action cleaner may not
clean as thoroughly as the scrubbing type cleaner.
The use of a non-scrubbing action, dry-type cleaning
cassette is not recommended.
After the player is cleaned, press and hold the eject
button for ve seconds to reset the CLEAN PLAYER
indicator. The radio will display --- to show the indicator
was reset.
Cassettes are subject to wear and the sound quality
may degrade over time. Always make sure the
cassette tape is in good condition before the tape player
is serviced.

Care of Your CDs
Handle CDs carefully. Store them in their original
cases or other protective cases and away from direct
sunlight and dust. If the surface of a CD 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 CDs. Pick up CDs by grasping the outer edges
or the edge of the hole and the outer edge.
Care of Your CD Player
The use of CD lens cleaners for CD players 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 xed mast antenna can withstand most car washes
without being damaged. If the mast should ever
become slightly bent, straighten it out by hand. If the
mast is badly bent, replace it.
Check occasionally to make 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 radio is the vehicle’s chime producer. To change
the volume level, press and hold pushbutton 6 with
the ignition on and the radio power off. The chime
volume level will change from the normal level to loud,
and Loud Chime Vol will appear on the radio display.
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 Soft Chime
Vol will appear on the radio display. Removing the radio
and not replacing it with a factory radio or chime will
disable vehicle chimes.
