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.

your radio. The feature works automatically by learning
a portion of the Vehicle Identification Number (VIN).

operate and LOC will be displayed.
When the ignition is off and RAP is not active, the
blinking red light indicates that THEFTLOCK is armed.
With THEFTLOCK activated, your radio will not
operate if stolen.

3-38 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 cleaning the cassette tape player with the
recommended non
-abrasive cleaning cassette, it is
possible that the cassette may eject, because the cut
tape detection feature on your radio may recognize it
as a broken tape. To prevent the cleaning cassette from
being ejected, use the following steps:
1. Turn the ignition to ON or ACC.
2. Turn the radio off.
3. Press and hold the TAPE CD or the TAPE AUX
button for five seconds. READY will appear on
the display and a cassette symbol will flash for
five seconds.
4. Insert the scrubbing action cleaning cassette.
5. Eject the cleaning cassette after the manufacturer's
recommended cleaning time.
When the cleaning cassette has been ejected, the broken
tape detection feature is active again.
You may also choose a non
-scrubbing action, wet-type
cleaner which uses a cassette with a fabric belt to clean
the tape head. 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.

Because this antenna is built into your rear window,
there is a reduced risk of damage caused by car washes
and vandals.
If you choose to add a cellular telephone to your vehicle,
and the antenna needs to be attached to the glass, be sure
that you do not damage the grid lines for the AM
-FM
antenna. There is enough space between the lines to
attach a cellular telephone antenna without interfering
with radio reception.
Vehicle Customization Settings
Your audio system can be used to control vehicle
customization settings using the DISP button when
the radio is off. See ªVehicle Customization Settingsº
in the Index for more information.
Chime Level Adjustment
Chime level adjustment is only available on RDS radios.
The radio is the vehicle chime producer. The chime is
produced from the driver's side front door speakers.
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 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.
Each time the chime volume is changed, three chimes
will sound as an example of the new volume selected.
Removing the radio and not replacing it with a factory
radio or chime module will disable vehicle chimes.
