3-23 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 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 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 (GM Part No. 12344789).The cut tape detection feature of your cassette tape
player may identify the cleaning cassette as a damaged
tape. To prevent the cleaning cassette from being
ejected, use the following steps:
1. Turn the ignition to RUN or ACCESSORY.
2. Turn the radio off.
3. Press and hold the TAPE button for two seconds
until the radio produces one beep. 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.
After the cleaning cassette is ejected, the cut tape
detection feature will be 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.

3-24
After you clean the player, press and hold the eject
button for three seconds to reset the CLN 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 you have your tape
player serviced.
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 signal surface 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 vehicle
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 occasionally 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 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 HI 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 LO 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.
