Understanding Radio Reception
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.
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.
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.
To help avoid hearing loss or damage:
0 Adjust the volume control to the lowest setting.
Increase volume slowly until you hear comfortably
and clearly.
I NOTICE:
I
I 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 Electronics 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, before adding sound equipment, check with
your dealer and be sure to check Federal rules
covering mobile radio and telephone units.

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 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 dealership
(GM Part No. 12344789).
When using a scrubbing action, non-abrasive cleaning
cassette, it is normal for the cassette to eject because
your unit is equipped with a cut tape detection feature
and a cleaning cassette may appear 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:
1.
2.
3.
4.
5.
Turn the ignition to RUN or ACCESSORY.
Turn the radio on.
Insert the scrubbing action cleaning cassette.
Within five seconds, press and hold the REV and
FWD buttons at the same time for three seconds. The
tape symbol on the display will flash, showing that
the cut tape detection feature is no longer active.
Eject the cleaning cassette after the manufacturer’s
recommended cleaning time.
If your vehicle is equipped with the AM-FM Stereo with Cassette Tape Player and Automatic Tone Control:
1. Turn the ignition to RUN or ACCESSORY.
2. Turn the radio off.

4.
5.
Press and hold the TAPE AUX button for five
seconds. The tape symbol
on the display will flash
for two seconds.
Insert the scrubbing action cleaning cassette while
the tape symbol is flashing.
Eject the cleaning cassette after the manufacturer’s
recommended cleaning time.
When the cleaning cassette has been ejected, the cut 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
EJECT for
five 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 car 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 fender.

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.
To avoid the possibility of the vehicles rolling, set
the parlung brake firmly on both vehicles involved in
the procedure. Put an automatic transmission vehicle
in
PARK (P) and a manual transmission vehicle in
NEUTRAL (N).
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!
NOTICE:
If you leave your radio on, it could be badly
damaged. The repair wouldn’t be covered
by
your warranty.
4. Open both hoods and locate the batteries. Find
the positive
(+) and negative (-) terminals on
each battery.
AUTION:
I
Using a match near a battery can cause battery
gas to explode. People have been hurt doing this,
and some have been blinded.
Use a flashlight if
you need more light.
Be sure the battery has enough water.
You don’t
need to add water to the ACDelco Freedom@
battery installed in every new
GM vehicle. But if
a battery has filler caps, be sure the right amount
of fluid is there. If it is low, add water to take care
of that first.
If you don’t, explosive gas could
be present.
Battery fluid contains acid that can burn you.
Don’t get it on you.
If you accidentally get it in
your eyes or on your
skin, flush the place with
water and get medical help immediately.

Downloaded from www.Manualslib.com manuals search engine Headlamps Fuses and Circuit Breakers
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. The
wiring circuits in your vehicle are protected from
short circuits by a combination
of fuses and circuit
breakers. 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.
