Remote Cassette Tape Player (If Equipped)
If your vehicle has this feature it is located in the center
console extension.Your tape player is built to work best with tapes that are
up to 30 to 45 minutes long on each side. Tapes longer
than that are so thin they may not work well in this player.
To load a cassette tape with the ignition off, first press
EJECT on the remote player. Then, insert the cassette
tape. The tape will play if the ignition is on but the radio
is off.
Once the tape is playing, use the control knobs for
VOL, AUTO TONE, BAL, FADE, BASS and TREB
just as you do for the radio. A lighted tape symbol
shows when a cassette tape is in the player. A lighted
arrow will also appear and show the direction of play
when a tape is active.
The player automatically senses if the cassette tape is
metal or CrO
2 and adjusts for best playback sound.
Anytime a cassette tape is inserted, the top side is
selected for play first.

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 do the following:
1. Adjust the volume control to the lowest setting.
2. Increase volume slowly until you hear comfortably
and clearly.

3-30
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, Delphi 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.
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.
Cleaning Your Remote Cassette Tape Player
Your remote tape player should be cleaned regularly
after every 50 hours of use. Your radio may display
CLN to indicate that you have used your remote
cassette tape player for 50 hours without resetting the
tape clean timer. If this message appears on the display,
your remote cassette 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.

3-31
The recommended cleaning method for your remote
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 casette, it is
possible that the cassette may eject, because the cut
tape detection feature on your tape player may recognize
it as a broken tape.
Use the following procedure to clean your remote
cassette tape player.
1. Turn the radio on.
2. Insert the recommended cleaning cassette.
3. If the cleaning cassette ejects, insert the cassette at
least three times to ensure thorough cleaning.
4. Eject the cleaning cassette if it does not eject on its own.After you clean the remote cassette tape player, press
and hold the RECALL button on the radio until CLN
appears on the radio display. While still pressing the
RECALL button, press the EJECT button on the remote
cassette tape player. Release both buttons when the radio
displays
---, indicating that the CLN indicator has
been reset.
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 cowl. If tightening is required, tighten
by hand, then with a wrench one quarter turn.

2. Get the vehicles close enough so the jumper cables
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 parking brake firmly on both vehicles involved in
the jump start procedure. Put the automatic
transmission in PARK (P), or a manual transmission
in NEUTRAL (N) before setting the parking brake.
If you have a four
-wheel-drive vehicle, be sure the
transfer case is in a drive gear not in NEUTRAL.
NOTICE:
If you leave your radio on, it could be badly
damaged. The repairs wouldn't be covered by
your warranty.
3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter or in the accessory power outlets. Turn off the
radio and all the lamps that aren't needed. This will
avoid sparks and help save both batteries. And it
could save your radio!
4. Open the hoods and locate the positive (+) and
negative (
-) terminal locations of the other vehicle.
Your vehicle has a remote positive (+) jump starting
terminal and a remote negative (
-) jump starting
terminal. You should always use these remote
terminals instead of the terminals on the battery.
The remote positive (+) terminal is located behind
a red plastic cover near the engine accessory drive
bracket. To uncover the remote positive (+) terminal,
open the red plastic cover.
The remote negative (
-) terminal is located on
the engine drive bracket on all V8 diesel engines.
On V8 engines it is marked ªGND.º
On V6 engines the remote negative (
-) terminal is
located on a tab attached to the engine accessory
drive bracket where it is marked ªGND.º
See ªEngine Compartment Overviewº in the Index
for more information on location.
