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 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.
Cleaning may be done with a scrubbing action,
non-abrasive cleaning cassette with pads which scrub
the tape head as the hubs
of the cleaner cassette turn. It
is normal for the cassette to eject while cleaning because
your unit is equipped with
a cut tape feature. To
temporarily override this feature (for one insertion), turn
the radio off and press and hold TAPE AUX until the
tape symbol flashes on the display, then insert
the
cassette again. Insert the cassette at least three times to
ensure thorough cleaning. A scrubbing action cleaning
cassette
is available through your GM dealer.
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. It
may not clean as thoroughly as the scrubbing type cleaner.
Cassettes are subject
to wear and the sound quality may
degrade over time. Always make sure that
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.
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 every once in a while to be sure the mast is still
tightened to the cowl.

I
Operating the engine with the air cleaner 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 off.
I NOTICE:
If the air cleaner 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
in place when you’re driving.
