3-61 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
CLEAN PLAYR 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 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.
If the cleaning cassette ejects, insert the cassette at least
three times to ensure thorough cleaning.
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.

3-62
After you clean the player, press and hold the eject
(upward pointing triangle) button for five seconds to
reset the CLEAN PLAYR indicator. The radio will
display CLEANED 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 Disc and
DVD 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.
Care of Your Compact Discs and DVDs
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 side without writing when
handling discs. Pick up discs by grasping the outer
edges or the edge of the hole and the outer edge.
Cleaning the Video Screen
Pour some isopropyl or rubbing alcohol on a clean cloth
and gently wipe the video screen. Do not spray directly
onto the screen and do not press too hard or too long on
the video screen.

3-63 Diversity Antenna System
Your AM FM antennas are located in the rear side
windows. Be sure that the inside surfaces of the rear side
windows are not scratched and that the lines on the glass
are not damaged. If the inside surfaces are damaged,
they could interfere with radio reception.
NOTICE:
Do not try to clear frost or other material from
the inside of the rear side windows with a razor
blade or anything else that is sharp. This may
affect your radio's ability to pick up stations
clearly. The repairs wouldn't be covered by
your warranty.
If you choose to add an aftermarket cellular telephone
to your vehicle, and the antenna needs to be attached to
the glass, be sure that you do not damage the grid lines
for the AM FM antennas or place the cellular telephone
antenna over the grid lines.
Chime Level Adjustment
The volume level of the vehicle's chimes can be
controlled by the radio. To change the volume level,
press and hold pushbutton 6 with the ignition on
and the radio power off. The chime volume level will
change from the normal level to loud, and LOUD will
be displayed on the radio. To change back to the default
or normal setting, press and hold pushbutton 6 again.
The chime level will change from the loud level to
normal, and NORMAL will be displayed.
