cooling is needed, use the vent mode to direct outside
air through your vehicle. Your vehicle also has the
flow

Using RDS
Your audio system is equipped with a Radio Data
System (RDS). RDS is a system that receives data
along with the audio of the FM station you are
currently tuned to.You can use RDS to display program information
and to control your radio. With RDS, the radio can
do the following:

Seek only to stations with the types of programs
you want to listen to,

seek to stations with traffic announcements,

receive announcements concerning local and
national emergencies, and

receive and display messages from radio stations.
RDS is always on. RDS features are only available for
use on FM stations which broadcast RDS information.
The RDS features of your radio rely upon receiving
specific RDS information from these stations. These
features will only work when the RDS information
is available. In rare cases, a radio station may broadcast
incorrect information that will cause the radio features
to work improperly. If this happens, contact the
radio station.
When you are tuned to an RDS station, the station name
will appear on the display, instead of the frequency.
Most RDS stations provide their station name, the time
of day and a Program Type (PTY) for their current
programming. Some stations also provide the name of
the current program.

Compact Disc Messages
CHECK CD: If this message appears on the radio
display and the disc comes out, it could be for one of the
following reasons:

The road is too rough. The disc should play when the
road is smoother.

The disc is dirty, scratched, wet or upside down.

The air is very humid. If so, wait about an hour and
try again.
If the CD is not playing correctly, for any other reason,
try a known good CD.
If any error occurs repeatedly or if an error can't be
corrected, contact your dealer. If your radio displays an
error message, write it down and provide it to your
dealer when reporting the problem.Theft-Deterrent Feature (If Equipped)
THEFTLOCK is designed to discourage theft of your
radio. The feature works automatically by learning a
portion of the Vehicle Identification Number (VIN). If
the radio is moved to a different vehicle, it will not
operate and LOCKED will be displayed.
When the radio and vehicle are turned off, the blinking
red light indicates that THEFTLOCK is armed.
With THEFTLOCK activated, your radio will not
operate if stolen.

3-29 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 or
CLEAN 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 cleaning the cassette tape player with the
recommended non
-abrasive cleaning cassette, it is
possible that the cassette may eject, because the cut
tape detection feature on your radio, may recognize it 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 and Compact Disc Player with Radio Data
System and Programmable Equalization, use the
following steps:
1. Turn the ignition to ON or ACCESSORY.
2. Turn the radio off.
3. Press and hold the CD TAPE button for five seconds.
READY will appear on the display for five seconds.
4. Insert the scrubbing action cleaning cassette.
5. Eject the cleaning cassette after the manufacturer's
recommended cleaning time.
When the cleaning cassette has been ejected, the broken
tape detection feature is active again.

3-30
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 the eject
button for five seconds to reset the CLEAN PLAYER
or CLN indicator. The radio will display CLEANED
or
--- 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 side without writing 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. If tightening is required, tighten
by hand, then with a wrench one quarter turn.
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.
