3-48 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 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.
If your vehicle is equipped with the AM
-FM Stereo with
Cassette Tape Player do the following:
1. Turn the ignition to RUN or ACCESSORY.
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.

If your vehicle is equipped with the AM-FM Stereo
with Cassette Tape and Compact Disc Player with
Radio Data System and Programmable Equalization
do the following:
1. Turn the ignition to RUN or ACCESSORY.
2. Turn the radio off.
3. Press and hold the TAPE CD button for five seconds.
READY will appear 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.
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.
After you clean the player, press and hold the cassette
eject symbol or the EJT button for five seconds to reset
the CLEAN or CLN indicator. The radio will display
CLEANED or
--- 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.

in the Index.
CAUTION:
Operating the engine with the air cleaner/filter
off can cause you or others to be burned. The air
cleaner not only cleans the air, it stops flame if
the engine backfires. If it isn't there, and the
engine backfires, you could be burned. Don't
drive with it off, and be careful working on the
engine with the air cleaner/filter off.
NOTICE:
If the air cleaner/filter is off, a backfire can
cause a damaging engine fire. And, dirt can easily
get into your engine, which will damage it.
Always have the air cleaner/filter in place when
you're driving.
