Comfort Controls
Air Conditioning with Electronic Controls
With these systems, you can control the heating, cooling
and ventilation in your vehicle. The systems work best if
you keep your windows closed while using them.
Fan Knob
The right knob with the fan symbol controls the force of
air you want. To turn the fan off, turn the knob to ªO.º
Temperature Control
If your system does not have the auxiliary temperature
control option, the center knob changes the temperature
of the air coming through the system. Turn this knob
toward red (clockwise) for warmer air. Turn it toward
blue (counterclockwise) for cooler air.
If your system does have the auxiliary temperature
control option, the center levers change the temperature
of the air coming through the system. The DRIV lever
sets the temperature for the driver and rear seat
passengers, and the PASS lever sets the temperature for
the front seat passenger. For maximum defroster
performance, set the DRIV and PASS levers at
full warm.

Mode Knob
The left knob has several settings to control the direction
of airflow. For each setting, set the temperature to a
comfortable setting.
MAX: This setting recirculates much of the air inside
your vehicle and sends it through the instrument panel
outlets. The air conditioning compressor will run
automatically in this setting unless the outside
temperature is below 40
F (4.5
C). (Even when the
compressor is running, you can control the temperature.)
A/C: This setting brings in outside air and directs it
through the instrument panel outlets. The air
conditioning compressor will run automatically in this
setting unless the outside temperature is below 40
F
(4.5
C). (Even when the compressor is running, you can
control the temperature.)
BI-LEVEL: This setting brings in the outside air
and directs it two ways. Half of the air is directed
through the instrument panel outlets. Most of the
remaining air is directed through the floor ducts and a
little to the defrost and side window vents. The air
conditioning compressor will run automatically in this
setting unless the outside temperature is below 40
F
(4.5
C). (Even when the compressor is running, you can
control the temperature.)
VENT: This setting brings in outside air and
directs it through the instrument panel outlets.
FLOOR: This setting sends most of the air
through the ducts near the floor. The rest comes out of
the defrost and side window vents.
DEFOG: This setting allows half of the air to go
to the floor ducts and half to the defrost and side
window vents. The air conditioning compressor will run
automatically in this setting unless the outside
temperature is below 40
F (4.5
C). (Even when the
compressor is running, you can control the temperature.)
DEFROST: This setting directs most of the air
through the defrost and side window vents. Some of the
air goes to the floor ducts. The air conditioning
compressor will run automatically in this setting unless
the outside temperature is below 40
F (4.5
C).
(Even when the compressor is running, you can control
the temperature.)

3-4 Air Conditioning
On very hot days, open the windows long enough to let
hot, inside air escape. This reduces the A/C compressor
load, which should help fuel economy.
For quick cool
-down on very hot days, use MAX with
the temperature control all the way in the blue area. If
this setting is used for long periods of time, the air in
your vehicle may become too dry.
For normal cooling on hot days, use A/C with the
temperature control in the blue area. The system will
bring in outside air and cool it.
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 control in the
middle. The system will bring in outside air and direct it to
your upper body, while sending slightly warmed air to
your lower body. You may notice this temperature
difference more at some times than at others.
Heating
On cold days use FLOOR with the temperature control
all the way in the red area. The system will bring in
outside air, heat it and send it to the floor ducts.
If your vehicle has an engine coolant heater, you can use
it to help your system provide warm air faster when it'scold 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
Your system has two settings for clearing the front and
side windows. To defrost the windows quickly, use
DEFROST with the temperature knob all the way in the
red area. To warm passengers while keeping the
windows clean, use DEFOG.
Rear Window Defogger
The rear window defogger
uses a warming grid to
remove fog from the
rear window. Press the area
labeled PUSH to turn the
defogger on.

3-5
It will turn itself off after about 10 minutes. If you turn it
on again, the defogger will only run for about five
minutes before turning off. You can also turn it off by
turning off the ignition or pressing the button again.
Do not attach anything like a temporary vehicle license
or decal across the defogger grid.
NOTICE:
Don't use a razor blade or something 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.
Don't put decals there because you might have to
scrape them off.
Ventilation System
Adjust the direction of airflow by moving the vents.
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.
Ventilation Tips

For mild outside temperatures when little heating or
cooling is needed, use VENT to direct outside air
through your vehicle.

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.
