Theft-Deterrent Feature
THEFTLOCK” is designed to discourage theft of your
radio. It works by using a secret code to disable all radio
functions whenever battery power
is removed.

ignored.
If ignored, the system plays normally and the
radio is not protected by the feature. If THEFTLOCK is
activated, your radio will not operate if stolen.
When THEFTLOCK
is activated, the radio will display
LOC
to indicate a locked condition anytime battery
power
is removed. If your battery loses power for any
reason, you must unlock the radio with the secret code
before it will operate.

The instructions which follow explain how to enter your
secret code to activate
the THEFTLOCK system. It is
recommended that you read through all nine steps
before starting the procedure.
NOTE: If you allow more than 15 seconds to elapse
between any steps, the radio automatically reverts

Understanding Radio Reception
FM Stereo
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.
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 if you ever get it.
Tips About Your Audio System
Hearing damage from loud noise is almost undetectable
until it is too late. Your hearing can adapt to higher
volumes
of sound. Sound that seems normal can be loud
and harmful to your hearing. Take precautions by
adjusting the volume control on your radio to
a safe
sound level before your hearing adapts
to it.
3-19

Downloaded from www.Manualslib.com manuals search engine To help avoid hearing loss or damage:
Adjust the volume control to the lowest setting.
Increase volume slowly until you hear comfortably
and clearly.
1 NOTICE:
Before you add any sound equipment to your
vehicle
-- like a tape player, CB radio, mobile
telephone or two-way radio
-- be sure you can add
what you want.
If you can, it’s very important to do
it properly. Added
sound equipment may interfere
with the operation
of your vehicle’s engine, Delco
radio or other systems, and even damage them.
Your vehicle’s systems may interfere with the
operation
of sound equipment that has been
added improperly
So, hefore adding sound equipment, check with
your dealer and
tw sure to check Federal rules
covering
mobile radio and telephone units.
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. 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.
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. Insert
the cassette at least three times to ensure thorough
cleaning.
A scrubbing action cleaning cassette is
available through your GM dealership.

can reach. but be sure the vehicles aren't touching
each other.
If they are, it could cause a ground
connection
you don't want. You wouldn't be able to
start your vehicle. and the bad grounding could
damage the electrical systems.
You could be injured if the vehicles roll. Set the
parking brake firmly on each vehicle. Put
an
automatic transmission in PARK (Pj or a manual
transmission
in NEUTRAL (N). If you have a
four-wheel-drive vehicle with a manual transfer case
shift lever. be sure the transfer case is not
in
NEUTRAL (N).
I A CAUTION:
An electric fan can start up even when the engine
is not running and can injure you. Keep hands,
clothing and tools away from any underhood
electric
Fan.
3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into
the cigarette
lighter. or accessory power outlets,
if you have this
option.
Turn off all lamps that aren't needed as well
as radios. This will avoid sparks and help save both
batteries.
In addition, it could save your radio!
I NOTICE:
If you leave your radio on, it could be badly
damaged. The repair wouldn't be covered
by
your warranty.
I A CAUTION:
If your vehicle has air conditioning, the auxiliary
electric fan under the hood can
start up even
when the engine
is not running and can injure
you. Keep hands, clothing and tools away from
any underhood electric fan.

Downloaded from www.Manualslib.com manuals search engine Headlamps
The headlamp wiring is protected by an internal circuit
breaker.
An electrical overload will cause the lamps to go
on and off, or in some cases to remain off. If this happens,
have your headlamp wiring checked right away.
Windshield Wipers
The windshield wiper motor is protected by a circuit breaker
and a fuse.
If the motor overheats due to heavy snow, etc., the
wiper will stop until the motor cools.
If the overload is caused
by some electrical problem, be sure
to get it fixed.
Power Windows and Other Power Options
Circuit breakers protect the power windows and other
power accessories. When
the current load is too heavy,
the circuit breaker opens and closes, protecting the
circuit until the problem is fixed or goes away.
Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses, circuit breakers
and fusible thermal links. This greatly reduces the
chance
of fires caused by electrical problems.
Look at the silver-colored band inside the fuse. If the
band is broken or melted, replace the fuse. Be sure you
replace a bad fuse with a new one of the identical size
and rating. If you
ever have a problem on the road and don't have
a
spare fuse, you can borrow one that has the same
amperage. Just pick some feature
of your vehicle that
you
can get along without -- like the radio or cigarette
lighter
-- and use its fuse, if it is the correct amperage.
Replace it as soon as
you can.
Instrument Panel Fuse Block
The fuse block is at the
driver's end
of the
instrument panel.
Remove the cover by turning the fastener
counterclockwise. Extra fuses and the fuse extractor
are
provided in the cover. To reinstall the fuse panel cover,
push
in and turn the fastener clockwise.
