Comfort Controls
This section tells you how to make your air system work
for you.
With this system, you can control the heating, cooling
and ventilation in your vehicle. Your vehicle also has a
flow
-through ventilation system described later in
this section.
Fan Knob
The left knob is the fan knob and selects the force of air
you want. Turn the knob clockwise to increase fan speed
and counterclockwise to decrease fan speed. The fan
must be turned on for the air conditioning compressor
to operate.Temperature Knob
The center knob controls the temperature of the air
coming through the system. Turn it clockwise (toward
the red area) for warmer air. Turn it counterclockwise
(toward the blue area) for cooler air.
Mode Knob
The right knob is used to select and determine the
direction of the air flowing into the vehicle.
UPPER: This setting directs outside air through
the instrument panel outlets.
BI-LEVEL: This setting directs outside air into
your vehicle in two ways. Cooler air is directed toward
your upper body through the front instrument panel
outlets, while warmed air is directed through the heater
ducts at your feet.
LOWER: This setting brings in most of the air
through the floor ducts. This setting is also used to send
air to the rear of the vehicle. Keep the area under the
front seats free of objects that could obstruct airflow to
the rear of the vehicle.

3-3
DEFOG: This setting directs air to the
windshield and through the floor ducts. This mode is
useful during cold or inclement weather because of your
vehicle's larger windshield area.
DEFROST: This setting directs most of the air to
the windshield and side window vents.
Mode Buttons
OUTSIDE AIR: Press this button
(the light will glow) to send outside air into your
vehicle. Using this setting while trying to defrost or
defog the windows will help clear the vents of moisture.
Press the RECIRCULATION button (the light on the
OUTSIDE AIR button will go off) to limit outside air
entering the vehicle. When the DEFOG or DEFROST
setting is selected, the system will automatically go to
OUTSIDE AIR mode.
RECIRCULATION: Press this button
(the light will glow) to limit the amount of fresh air
entering your vehicle by recirculating much of the air
inside your vehicle. You may use this setting to limit
odors entering your vehicle. Press the OUTSIDE AIR
button (the light on the RECIRCULATION button will
go off) to let outside air circulate into the vehicle.Operating the Heating/Ventilation/Air Conditioning
(HVAC) system in the RECIRCULATION mode may
cause fogging of the vehicle's windows when the
weather is cold and damp. To clear the fog, switch the
HVAC system to either the DEFOG or DEFROST mode
and increase the fan speed. To avoid re
-fogging of
the windows, operate the HVAC system in the
OUTSIDE AIR mode.
Air Conditioning
On very hot days, your vehicle will cool down more
quickly and economically if you open the windows long
enough to let hot, inside air escape. For all settings,
adjust the temperature control knob and fan speed
as desired.
To get maximum cooling or a quick cool
-down on very
hot days, press the A/C and RECIRCULATION buttons
(the lights will glow) and turn the temperature knob
counterclockwise (toward the blue area). Adjust the
mode knob to direct the air to the desired location.
This setting should not be used for long periods of time
because the air may become too cold and dry. Push the
A/C button again (the light will go off) to turn off the
air conditioning.

3-4
When the air conditioner compressor is on, you may
sometimes notice slight changes in your vehicle's engine
performance and power. This is normal. The system is
designed to help fuel economy while it maintains the
desired cooling level.
The air conditioner removes moisture from the air, so
you may sometimes notice water dripping from under
your vehicle's engine compartment when it is idling or
after it has been turned off. This is normal.
Heating
Turn the temperature knob clockwise (toward the red
area) to warm the air.
In the LOWER setting, outside air will be brought in
and sent through the floor outlets. The heater works best
if you keep your windows closed while using it.
The BI
-LEVEL setting is designed for use on sunny
days when the air is only moderately warm or cool.
On days like these, the sun may adequately warm your
upper body, but your lower body may not be warm
enough. For the best results, turn the temperature
control knob to the middle position, and then adjust it
for comfort.If you have the optional engine coolant heater and use it
during cold weather, 0
F (
-18
C) or lower, your heating
system will provide heat more quickly because the
engine coolant is already warmed. See ªEngine Coolant
Heaterº in the Index.
Defogging and Defrosting
To rapidly defrost the windshield, turn the temperature
control knob all the way clockwise (to the red area) and
turn the mode knob to DEFROST. Adjust the fan to the
highest speed.
To keep the windshield clear and bring in heated air
through the heater ducts, turn the mode knob
to DEFOG.
When the temperature outside is above freezing, the air
conditioner compressor will run in these settings to help
remove moisture from the air.
Your vehicle is equipped with side window defogger
vents located on the top of the instrument panel. For
additional side window defogging, turn the mode knob
to the BI
-LEVEL setting and adjust the fan to the
highest speed. Aim the side vents on the instrument
panel toward the side windows. For increased airflow to
the side vents, close the center vents.

3-5
Operating the HVAC system in the RECIRCULATION
mode may cause fogging of the vehicle's windows when
the weather is cold and damp. To clear the fog, switch
the HVAC system to either the DEFOG or DEFROST
mode and increase the fan speed. To avoid re
-fogging of
the windows, operate the HVAC system in the
OUTSIDE AIR mode.
For additional information, refer to
ªRECIRCULATIONº earlier in this section.
Rear Window Defogger (If Equipped)
Press the REAR button
(the light will glow) to
warm the defogger grid on
the rear window and to turn
on the heated outside
rearview mirrors.
The system will turn off automatically after about
10 minutes of use. If you turn it on again, the defogger
will operate for about five minutes. You can also turn
the defogger off by turning off the ignition or by
pressing the button again.Do not attach a temporary vehicle license across the
defogger grid on the rear window.
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.
Rear Climate Control (Option)
If you have the optional rear climate control, the rear
seat passengers can control the temperature and the
amount of air directed to the rear of the vehicle. You can
also adjust the amount of air directed to the rear of the
vehicle using the front fan control knob.
When it's cold outside, set the main climate control
knob to LOWER, DEFOG or DEFROST, to send air to
the rear of the vehicle through the lower vents.
Set the main climate control mode knob to UPPER or
BI
-LEVEL to send air to the rear of the vehicle through
the headliner outlets.

3-6
To send conditioned air to the rear of the vehicle, press
the A/C button (the light will glow) on the main climate
controls. If you do not select A/C, air directed to the rear
of the vehicle will be cabin temperature.
Rear Fan Control
This option comes with the rear climate controls.
Keep the area around the base of the center instrument
panel console and the area between and under the front
seats free of objects that would obstruct airflow to the
rear of the vehicle.
The rear fan control is
located below the
climate control system,
in the switchbank.Turn the fan to the desired setting for the amount of air
to be directed to the rear of the vehicle. The temperature
of the air will be the same as the air in the front of the
vehicle. The rear fan control in the instrument panel
switchbank has an ªRº setting which allows the rear
passengers to use the rear climate control knobs to
adjust the air through the rear air outlets.
Rear Comfort Controls
The rear climate control knobs are in a panel next to the
second row seat. If your vehicle has the optional dual
sliding doors, the panel is above the driver's seat.

3-7
Turn the temperature knob counterclockwise (to the blue
area) for cooler air, or clockwise (to the red area) for
warmer air.
To maintain a comfortable temperature in the rear, use
either rear fan control to adjust the force of air coming
through the rear outlets.
Select the desired climate control mode using the
directional controls on the instrument panel (see ªMode
Knobº earlier in this section). The mode you choose will
regulate both the front and rear climate control systems.Rear Air Vents
To maximize airflow through the rear heater outlet, place
the left bucket seat in the second row in the forward
position (see ªAdjusting Rear Seatsº in the Index).
The vent behind the left rear seat is the cold air return
vent. Be sure to keep it free of obstructions.
Keep the area around the base of the center instrument
panel console, between and under, the front seats free of
objects that could obstruct airflow to the rear.

3-8 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.
Your vehicle has air outlets that allow you to adjust the
direction and amount of airflow inside the vehicle. Push
the outlet up or down to direct the airflow to your
preference. Increase or reduce the amount of airflow by
opening and closing the louvers. Opening and closing
the louvers will also direct airflow from side to side.
The air
-flow through the vents can be shut off
completely by turning the thumbwheel next to each
outlet all the way down. You can also stop outside air
from entering by turning the fan to OFF and pushing the
RECIRCULATION button.
Ventilation Tips

Keep the hood and front air inlet free of ice, snow or
any other obstruction (such as leaves). This will
allow the heater and defroster to work much better,
reducing the chance of fogging the inside of
your windows.

When you enter a vehicle in cold weather, turn the
fan knob to ª5º, the highest setting, 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 area around the base of the center
instrument panel console and the air path under the
front seats clear of objects. This helps air to circulate
throughout your vehicle.

In cold weather, operating the system in the
OUTSIDE AIR mode will improve the time it takes
to warm the vehicle.
