Comfort Controls
This section tells you how to make your air system work
for you. Your comfort control system uses
ozone
-friendly R-134a refrigerant.
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 counterclockwise
(toward the blue area) for cooler air. Turn it clockwise
(toward the red area) for warmer air.
Mode Knob
This knob controls the direction of where the air will
enter 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.

DEFOG: This setting directs air to the windshield
and through the floor ducts. This mode is particularly
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
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.
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.
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.
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.

3-4 Heating
Turn the temperature knob clockwise (toward the red
area) to warm the air.
In the LOWER mode, 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.

3-7
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 and between and under the front seats free
of objects that could obstruct airflow to the rear.

SCV: Your system has a feature called
Speed
-Compensated Volume (SCV). With SCV, your
audio system adjusts automatically to make up for road
and wind noise as you drive. Set the volume at the
desired level. Turn the control ring behind the upper
knob clockwise to adjust the SCV. Then, as you drive,
SCV automatically increases the volume, as necessary,
to overcome noise at any particular speed. The volume
level should always sound the same to you as you drive.
If you don't want to use SCV, turn the control all the
way down. Each notch on the control ring allows for
more volume compensation at faster vehicle speeds.
