Comfort Controls
This section tells you how to make your air system work
for you.
Climate Control Panel
Your vehicle is equipped with an electronic climate
control system. This system can automatically adjust
and control temperature, fan speed, air delivery mode,
air conditioning operation and air intake. You can use
the AUTO (automatic) setting or override the automatic
operation by manually adjusting the controls. If your
vehicle is equipped with the climate control
personalization feature, you will be able to recall your
preferred climate control settings using your remote
keyless entry transmitter. See ªClimate Control
Personalizationº in the Index.Manual Operation
To turn the system on, press the knob located on the left
side of the climate control panel.
~MODE!: Press MODE to deliver air through the
floor, instrument panel or windshield outlets. The
system will stay in the selected mode until MODE is
pressed again. The current mode is displayed on the
climate control panel when MODE is pressed. Press the
up or down arrow to cycle through the following modes:


(Upper): This setting directs the airflow
through the instrument panel outlets.


(Bi-Level): This setting directs airflow into
your vehicle in two ways. Cooler air is directed to
the upper portion of your body through the four
instrument panel outlets while warmer air is directed
to the floor.


(Floor/Defrost): This setting directs airflow to
the floor outlets and toward the windshield.


(Floor): This setting directs airflow through
the floor outlets. Some air is diverted to the
windshield to minimize fogging.

3-3
!~(Fan): This switch adjusts the fan speed. Press the
up arrow to increase fan speed and the down arrow to
decrease it.
(Recirculation): Press this button to limit the
amount of outside air entering your vehicle. This is
helpful when you are trying to cool the air quickly or
limit odors entering your vehicle. Press this button again
to turn off the recirculation feature. If you notice the
windows fogging, turn off the recirculation feature.
Recirculation is not available in the defrost mode.
FRONT (Defrost): Press this button to quickly
remove fog or frost from the windshield. This setting
sends most of the airflow to the windshield with only a
small amount to the floor outlets. The air conditioning
compressor will operate in this mode.
A/C (Air Conditioning): Press this button to turn the
air conditioning compressor on and off. The system will
cool and dehumidify the air inside the vehicle. A/C
cannot be turned off in defrost mode.PASS OFF (Passenger's Climate Control): Pressing
this button will turn off or on the climate controls for the
passengers. When this feature is active, the driver's
climate control settings are used for both the front and
rear seating areas.
Driver's Temperature Knob: The knob located on the
left side of the climate control panel is used to adjust the
air temperature coming through the system for the
driver's side of the vehicle while the passenger's side
controls are active. Turn the knob clockwise to increase
the temperature displayed on the climate control panel,
or turn the knob counterclockwise to decrease the
temperature. Press the knob to turn the climate control
system off.
~PASS TEMP! (Passenger's Temperature): This
switch is used to increase or decrease the temperature of
the air for the right front passenger independent of the
driver's setting.
Press the up arrow to increase the temperature setting or
the down arrow to decrease it.

3-4
Automatic Operation
AUTO: This button is used to select the automatic
operation of the climate control system. When the
automatic operation is active, AUTO will appear on
the display.
A sensor will control the air delivery mode. Air will
come from the floor, the instrument panel or windshield
outlets. The fan speed and use of air conditioning
will vary as the system maintains the selected
temperature setting.
Do not cover the electronic solar sensor located on top
of the instrument panel near the windshield. The sensor
is used by the automatic system to regulate temperature.
See ªElectronic Solar Sensorº later in this section for
more information.
To find your comfort zone, start with the 75
F (24
C)
setting and allow about 30 minutes for the system to
regulate. Turn the driver's temperature knob to adjust
the temperature if necessary. If you choose 60
F
(16
C), the system will remain at that maximum cooling
setting and will not regulate fan speed. If you choose
90
F (32
C), the system will remain at that maximum
heating setting and will not regulate fan speed. Choosing
either maximum setting will not cause the system to heat
or cool any faster.In cold weather, when the system senses the need for
heat, the airflow will be directed out of the floor outlets.
As the interior temperature approaches the desired
setting, the fan speed will decrease. To maintain interior
comfort, the airflow may move to the instrument panel
air outlets and floor outlets (bi
-level mode). On bright
sunny days in cold weather, the airflow may come out of
the instrument panel outlets in A/C mode to maintain
comfort and prevent stuffiness.
When the automatic setting is active, the air
conditioning compressor cycles when needed to cool the
air. If your vehicle is sitting out on a hot day and AUTO
is active, the air will first flow out of the floor outlets for
a few seconds. This is normal. This is to remove hot air
from the air outlets. As the air is cooled, the airflow will
move through the instrument panel outlets. If you start
your vehicle with the fan setting on HI, it will skip the
air conditioning purge and the system will be in
manual mode.

3-6 Air Conditioning
On 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. Then keep your windows closed
for the air conditioner to work its best.
Press the driver's temperature knob to turn the system
on manually. You may also need to adjust the
temperature and fan speed. The system will cool and
dehumidify the air inside the vehicle.
When the system is in AUTO, it will use recirculation as
necessary to cool the air.
Heating
Press MODE to select floor. Adjust the interior
temperature manually to a comfortable level. If the fan
speed needs adjustment, press the up or down arrow.
Outside air will be brought in, warmed and sent through
the floor, instrument panel outlets. The heater works
best if you keep your windows closed while using it.
In AUTO, the fan will not run at high speed to minimize
warm
-up time.
Defogging and Defrosting
Use FRONT on cool and humid days to keep the
windshield and side windows clear. This setting will
remove fog or ice from the windshield quickly in
extremely humid or cold conditions. If you desire to
have more air on your feet, turn the control to the
floor/defrost mode.
Press FRONT to activate the defrost mode. Adjust the
fan speed by pressing the up or down arrow on the fan
button. You may also adjust the temperature by turning
the driver's temperature knob. If you select floor/defrost
from AUTO, the system will control the fan speed and
temperature for you.
Recirculation is not available in the defrost mode, and
the A/C system cannot be turned off in this mode.

3-9
~ TEMP ! (Temperature): Press this switch to
manually adjust the temperature. Press the up arrow to
increase the temperature or the down arrow to decrease
it. The current temperature will appear on the display
above the climate control panel.
The front seat climate control panel has an AUTO
button that can override the climate controls of the rear
seating area automatically. When AUTO is pressed, the
rear automatic mode is selected and the rear air
temperature and mode will readjust to coincide with the
setting selected for the front seating area.
The PASS OFF button on the front climate control panel
allows the settings for the driver to be used for the front
and rear seat areas.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 heater or the air
conditioning fan is in operation. See ªRecirculationº
listed previously in this section for more information.
The front outlets are located in the center and at each
side of the instrument panel. You can adjust the
direction of airflow by moving the center control levers
or you can stop the airflow by moving the thumbwheel
located on each outlet downward.
