DEFOG: This position divides the airflow
between the floor outlets and the windshield defroster
vent. The air conditioning compressor will run
automatically in this position when it is needed to help
dry the air in the vehicle.
FRONT DEFROSTER: This position directs
most of the airflow through the window defroster vent.
Some of the air goes to the floor outlets. The air
conditioning compressor will run automatically in this
position when it is needed to help dry the air in
the vehicle.
OUTSIDE AIR: Press this button to force the
system to use outside air.
Pressing the OUTSIDE AIR button will cancel the
RECIRCULATION button.
RECIRCULATION: Press this button to limit
the amount of fresh air entering your vehicle. This is
helpful when you are trying to limit odors entering your
vehicle. Press it again to turn off the recirculation.
Pressing the RECIRCULATION button will cancel the
OUTSIDE AIR button.Air Conditioning Compressor Button
Press A/C to operate the air conditioner compressor.
The indicator light will glow when the button is pressed
to indicate that the air conditioning system has been
turned on. The fan knob must be set to a speed.
Air Conditioning
The air conditioner and heater work best if you keep
your windows closed while using them. Your vehicle
also has the flow
-through ventilation system described
later in this section.
On very hot days, open the windows long enough to
let hot inside air escape. This reduces the time it takes
for your vehicle to cool down, which should help
fuel economy.
On cool, but sunny days, the sun may warm your upper
body, but your lower body may not be warm enough.
You can use BI
-LEVEL with the temperature knob in
the middle and the A/C indicator light glowing. The
system will bring in outside air and direct slightly
warmer air to your lower body.
For normal cooling on hot days, use VENT with the
temperature knob in the blue area and the A/C indicator
light glowing. The system will bring in outside air and
cool it.

3-4 Heating
On cold days, use FLOOR and the outside air button
with the temperature knob all the way in the red area.
The system will bring in outside air, heat it and send it to
the floor outlets.
Your vehicle has heat ducts that are directed toward the
rear seat. Keep the area under the front seats clear of
obstructions so that the heated air can reach the rear
seat passengers.
If your vehicle has an engine coolant heater, you can use
it to help your system provide warm air faster when it's
cold outside (0
F (
-18
C) or lower). An engine coolant
heater warms the coolant your engine and heating
system use to provide heat. See ªEngine Coolant
Heaterº in the Index.
Defogging and Defrosting Windows
Your system has two settings for clearing the front and
side windows. For each setting, adjust the temperature
control as desired.
To defrost the front window quickly, turn the
temperature control knob all the way in the red area.
Use FRONT DEFROST and adjust the fan to the highest
speed. To warm passengers while keeping the front
window clean, use DEFOG.If you select RECIRCULATION while in the VENT,
BI
-LEVEL or FLOOR modes, humid air can recirculate
inside the vehicle and allow moisture to form on the
windows. If this happens either press the A/C button
to on or select FRONT DEFROSTER or the
DEFOG modes.
Your vehicle is equipped with side window defogger
vents. The side window defogger vents are located on the
outside of the side instrument panel vents. To defrost the
side windows, turn the temperature control knob all the
way in the red area. Use FLOOR and adjust the fan to the
highest speed. To control fogging of the windows, turn
the temperature control knob all the way in the red area.
Use DEFOG and adjust the fan to the highest speed.
To defog the side windows while using air conditioning,
use BI
-LEVEL and adjust the fan to the highest speed
and press the A/C button so that the indicator light is
glowing. For added airflow to the side windows aim
the side vents toward the windows and close the
center vents.

3-5 Rear Window Defogger
The rear window defogger
uses a warming grid to
remove fog from the
rear window.
Press the defogger button. The indicator light will glow.
The rear window defogger will turn itself off after about
10 minutes after the first time the button is pressed, and
after five minutes each additional time the button is
pressed. You can turn the defogger off by pressing the
button again or turning off the ignition.Do not attach a temporary vehicle license across the
defogger grid on the rear window.
NOTICE:
Don't use a razor blade or anything else sharp on
the inside of the rear window. If you do, you
could cut or damage the warming grid, and the
repairs wouldn't be covered by your warranty.

3-6 Ventilation System
For mild outside temperatures when little heating or
cooling is needed, use VENT to direct outside air
through your vehicle. Your vehicle also has the
flow
-through 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 air conditioning
fan is running.
You will find air outlets in the center and on the sides of
your instrument panel.You can direct the airflow side to side by moving the
sliding levers. The outlet can be tilted up and down also.
To control the amount of airflow through the outlets,
rotate the thumbwheel.
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 your windows.

When you enter a vehicle in cold weather, adjust the
mode knob to FLOOR and the fan to the highest
speed for a few moments before driving off. This
helps clear the intake ducts of snow and moisture
and reduces the chance of fogging the inside of
your windows.

Keep the air path under the front seats clear of
objects. This helps air circulate throughout
your vehicle.

To prevent circulation of outside air, press the
recirculation button. This will close all outside vents.

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.

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.
