DEFOG: This setting directs the majority of the
airflow to the lower floor outlets and the front defroster.
A small amount of airflow is directed to the side
window defroster outlets. This mode can be useful to
remove the moisture from the inside of the windshield
when the outside temperature is cold or the humidity
is high.
DEF (Defrost): This setting directs the majority
of the airflow to the windshield with some airflow to
the side window defrosters and lower floor outlets.

knob clockwise.
RECIRC ON: Press this button to limit the amount of
outside air entering your vehicle. This is helpful when

for some other reason. The RECIRC ON button and the
AUTO
-PUSH knob may be selected at the same time.
The system will remain in RECIRC ON until the
ignition is turned off, then the system will return back to
the previously selected mode. RECIRC ON may be
selected in all manual airflow modes except
front defrost.Operating the RECIRC ON mode in cold temperatures
or under high humidity conditions may cause moisture
to form on the inside of the windshield. If this condition
occurs, deselect the RECIRC ON button.
A/C ON: Press this button to turn the air conditioning
on and off. If the system is operating in the automatic
mode, the A/C ON indicator light will automatically
illuminate. In the auto mode, the A/C compressor will
only operate when the system determines it is needed.
OFF: Turn the AUTO
-PUSH knob to OFF. Turning the
system off will cause the fan to turn off and the airflow
to be directed out the lower floor outlets. The system
will still try to keep the interior of the vehicle at the
previously chosen comfort setting. The outside
temperature will show in the display when the system is
set to OFF.

Playing a Cassette Tape
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.
The longer side with the tape visible should face to the
right. If the ignition is on, but the radio is off, the tape
can be inserted and will begin playing. If you hear
nothing but a garbled sound, the tape may not be in
squarely. Press EJECT to remove the tape and start over.
While the tape is playing, use the VOL, FADE, BAL,
TREB, BASS, TONE, SEEK and SCAN controls just as
you do for the radio. (The TONE control is not available
on the Bose radio.) Other controls may have different
functions when a tape is inserted. The display will show
TP with a box around it and an arrow to show which
side of the tape is playing.
Your tape bias is set automatically. When a metal or
chrome tape is inserted, HI
-BIAS appears on the
display. If you want to insert a tape when the ignition is
off, first press EJECT or RCL.If E and a number appear on the radio display and the
tape won't play because of an error, it could be that:

tape hubs. Remove the tape. Hold the tape with the
open end down and try to turn the right hub
counterclockwise with a pencil. Turn the tape over
and repeat. If the hubs do not turn easily, your tape
may be damaged and should not be used in the
player. Try a new tape to make sure your player is
working properly.

E11: The tape is broken. Try a new tape.
If any error occurs repeatedly or if an error can't be
corrected, please contact your dealer. If your radio
displays an error number, write it down and provide it to
your dealer when reporting the problem.

another part of the tape. Press the button again to return
to playing speed. The radio will play the last selected

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.
The THEFTLOCK feature for the radio may be used or
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.
Activating the Theft
-Deterrent Feature
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 to
time and you must start the procedure over at Step 4.
