A/C: This button turns the air conditioning
compressor off or on under most conditions. The light
on the A/C button will come on when the compressor is
operating in either the automatic or manual mode. The
air conditioning does not operate at temperatures below
approximately 35
F to 40
F (2
C to 4
C). The light
on the A/C button will flash if pressed when air
conditioning is not available. The air conditioning cools
and dehumidifies the air coming into the vehicle. The air
conditioning cannot be turned off in DEFROST and
DEFOG, as it helps to remove moisture from the
vehicle. It also helps to keep the windows clear.
If the system is operating in the AUTO mode, turning
the air conditioning off will delete AUTO from the
digital display and show current mode and fan settings.
The AUTO button must be pressed to return to the
automatic mode operation.
The air conditioning may be forced off at high engine
speeds or high engine oil or coolant temperatures. OUTSIDE AIR: Press this button to provide
outside air. The light on this air intake button will come
on to show when it is operating. When in the AUTO
mode, the system automatically selects OUTSIDE AIR
instead of recirculate, as required, to control the
temperature in the vehicle. By pressing OUTSIDE AIR,
the system will lock into the outside air mode. Any
adjustment to the air intake must then be made
manually. OUTSIDE AIR should be used when trying to
defrost or defog windows to help reduce moisture inside
of the vehicle.
RECIRCULATE: Press this button to limit the
amount of outside air entering the vehicle. The light on
this air intake button will come on to show when it is
operating. Recirculate is helpful when you are trying to
cool the air quickly or trying to limit odors and dust
from entering the vehicle. When in the AUTO mode,
the system automatically selects recirculate to cool the
vehicle's temperature. By pressing this button, the
system will lock into the recirculated air mode.
Any adjustment to the air intake must then be made
manually. Recirculation is not available when using the
defrost or defog mode because outside air is need to
reduce moisture inside of the vehicle.

Outside Air Temperature Sensor
This sensor is located in the air intake under the front
bumper of the vehicle. Information from this sensor
is used for the outside air temperature readings
shown on the digital display for the automatic climate
control system.
If the outside temperature goes up, the displayed
temperature will not change until:

The vehicle's speed is above 16 mph (26 km/h) for
one and a half minutes.

The vehicle's speed is above 45 mph (72 km/h) for
one minute.
These delays help prevent false readings. If the
temperature goes down, the outside temperature display
is updated immediately.
If the vehicle has been turned off for more than three
hours, the current outside temperature will be shown
when you start the vehicle. If it has been turned off for
less than three hours, the temperature will be recalled
from the previous vehicle operation.Inside Temperature Sensor
This sensor is located to the left of the ignition switch.
The automatic climate control system uses this sensor to
receive information, so if you block or cover it, the
system will not function properly.
Air Conditioning
On very hot days, the vehicle will cool down more
quickly and economically if you open the windows long
enough to let hot inside air escape. Then keep the
windows closed in order to allow the air conditioning to
work best. Maximum cooling will occur when the
recirculate setting is operating, airflow direction is in the
upper mode, and the temperature knob (on a manual
climate control system) is turned all the way to the blue
area. These settings will be selected by the automatic
electronic dual climate control system if operating in
AUTO when maximum cooling is required.
When the air conditioning is on, you may
sometimes notice slight changes in the vehicle's engine
performance and power. This is normal. The system is
designed to help fuel economy while maintaining the
desired cooling level.
The air conditioning removes moisture from the air,
so you may notice water dripping from under the
vehicle when it is idling or after it has been turned off.
This is normal.

3-12
The rear window defogger uses a warming grid to
remove fog from the rear window. Do not attach
anything like a temporary vehicle license or a decal
across the defogger grid on the rear window.
NOTICE:
Don't use a razor blade or something sharp on
the inside of the rear window. If you do, you
could cut or damage the warming grid, and
repairs wouldn't be covered by your warranty.
Ventilation System
Your vehicle's flow-through ventilation system supplies
outside air into the vehicle when it is moving. Outside
air will also enter the vehicle when the fan is running.
Ventilation Tips

Keep the hood and front air inlet free of ice, snow or
any other obstruction (such as leaves). The heater
and defroster will work far better, reducing the
chance of fogging the inside of the windows.
When you enter a vehicle in cold weather, turn the
fan to the highest speed for a few moments before
driving off. This helps clear the intake outlets of
snow and moisture, and reduces the chance of
fogging the inside of the windows.

Keep the area around the base of the center instrument
panel console and air path under the seats clear of
objects. This helps air circulate throughout the vehicle.
Audio Systems
Your audio system has been designed to operate easily
and give years of listening pleasure. You will get the
most enjoyment out of it if you acquaint yourself with it
first. Find out what your audio system can do and how
to operate all its controls, to be sure you're getting the
most out of the advanced engineering that went into it.
Your vehicle has a feature called Retained Accessory
Power (RAP). With RAP, you can play your audio
system even after the ignition is off. See ªRetained
Accessory Powerº in the Index.

3-27 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 has been interrupted. 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.
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 4.1. Write down any three or four
-digit number from
000 to 1999 and keep it in a safe place separate from
the vehicle.
2. Turn the ignition to ACC or ON.
3. Turn the radio off.
4. Press the 1 and 4 buttons together. Hold them down
until
--- shows on the display. Next you will use the
secret code number which you have written down.
5. Press MN and 000 will appear on the display.
6. Press MN again to make the last two digits agree
with your code.
7. Press HR to make the first one or two digits agree
with your code.
8. Press AM
-FM after you have confirmed that the
code matches the secret code you have written down.
The display will show REP to let you know that you
need to repeat Steps 5 through 7 to confirm your
secret code.
9. Press AM
-FM and this time the display will show
SEC to let you know that your radio is secure. The
LED indicator by the volume control will begin
flashing when the ignition is turned off.
