Comfort Controls
This section tells you how to make your air system work
for you.
Manual operation of the system is described first,
followed by automatic operation. See ªAutomatic
Operationº later in this section for more information.
Climate Control System
Manual Operation
To turn the system on, press the PWR button located on
the driver's side of the climate control panel.
!~(Mode): This switch selects the direction of
the airflow through the vehicle. Press the up or down
arrow to scroll through the available modes. The symbol
for the current mode will be displayed on the climate
control panel.
Regardless of the mode selected, there will be some air
flowing to the outboard outlets unless you close the
outlet. See ªVentilation Systemº later in this section for
more information.
The following modes can be selected:


(Vent): 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
instrument panel outlets while warmer air is directed
to the floor ducts.

3-3

(Floor/Defrost): This setting directs airflow to
the floor ducts and toward the windshield, with some
air diverted toward the outboard outlets to defog the
side windows.


(Floor): This setting directs airflow
through the floor ducts. Some air is diverted
to the windshield and outboard outlets to
minimize fogging.
!~ (Fan): This switch adjusts the fan speed.
Press the up or down arrow to increase or decrease the
fan speed.
(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 and
will automatically turn off after 10 minutes if
floor/defrost mode is selected.
(Defrost): Press this button to quickly remove
fog or frost from the windshield. This setting sends
most of the airflow to the windshield with a small
amount diverted to the outboard outlets to minimize
fogging. The air conditioning compressor may operate
in this mode.
A/C OFF (Air Conditioning Off): Press this button
to turn off the air conditioning compressor. AC OFF will
appear on the display. Press the button again to turn the
compressor back on. When the compressor is on, the
system will cool and dehumidify the air inside the
vehicle. The compressor cannot be turned off in
defrost mode.
(Driver's Temperature Switch): This switch is used
to adjust the air temperature for the driver's side of the
vehicle. To adjust the temperature, press the up or down
arrow located on the PWR button. The temperature will
increase or decrease with each press of an arrow.
The driver's set temperature is always displayed when
the climate control system is on regardless of whether or
not the system is in AUTO. See ªAutomatic Operationº
later in this section for more information on the
AUTO button.

3-4
(Passenger's Temperature Switch): This switch is
used to increase or decrease the temperature of the air
for the passengers independent of the driver's setting.
To turn the system on, press the PWR button located
on the passenger's side of the climate control panel.
To adjust the temperature, press the up or down arrow
on the PWR button. The temperature will increase or
decrease with each press of an arrow.
If the passenger's temperature switch is off, the driver's
temperature switch controls the temperature for the
entire vehicle.
The passenger's side temperature is only displayed
when the passenger's side temperature switch is on.
Automatic Operation
AUTO (Automatic Climate Control): This button is
used to select the automatic operation of the climate
control system. When the automatic operation is active,
AUTO will appear next to the fan and mode settings on
the display.There are three sensors in the climate control system.
One monitors the sun's solar radiation, another monitors
temperature of the air inside the vehicle, and a third
monitors the temperature outside the vehicle. The
climate control system will vary the fan speed, air
delivery mode and use of the air conditioning
compressor to maintain the set temperature based on the
information received from these sensors. See ªDriver's
Temperature Switchº and ªPassenger's Temperature
Switchº listed previously for more information on
setting a temperature.
To find your comfort zone, start with the 75
F (24
C)
setting and allow approximately 10 to 30 minutes for the
system to regulate. Adjust the temperature if necessary.
If you choose either the lowest temperature setting,
60
F (16
C), or the highest temperature setting,
90
F (32
C), the system will not cool or heat any
faster, but the system will stay at that setting without
regulating fan speed.
To avoid blowing cold air in cold weather, the system
will start at lower fan speeds until warm air is available.
The length of reduction depends on the outside air
temperature, engine coolant temperature or the time
since the engine was last started. As the engine coolant
warms up, the fan speed will gradually increase.

3-5
Interior Temperature Sensor
This sensor
monitors the interior
temperature of the
vehicle. It is located to
the right of the
steering wheel on the
instrument panel.
While the climate control system is in AUTO, the
system uses both the interior temperature sensor and the
electronic solar sensor to automatically adjust the
temperature and airflow in the vehicle. See ªElectronic
Solar Sensorº following for more information. Be sure
not to cover the sensor with anything. If you do, the
automatic climate control system will not work properly.Electronic Solar Sensor
This sensor monitors the sun's solar radiation. It is located
on top of the instrument panel near the windshield.
While the climate control system is in AUTO, the system
uses the information collected by the electronic solar
sensor to automatically adjust the temperature and airflow
to maintain your comfort. The climate control system may
supply cooler air to one side of your vehicle, if that side is
facing the sun. Be sure not to cover the sensor on top of
the instrument panel. If you do, the automatic climate
control system will not work properly.

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.
While the system is in AUTO, it will use recirculation
as necessary to cool the air.
Defogging and Defrosting
When the mode switch is set for floor/defrost or the
defrost button is pressed, outside air will be selected
automatically. This helps clear the windshield more
quickly. Adjust the temperature and set the fan speed to
the highest setting. When the windshield is clear, adjust
the fan speed for maximum defrosting to a lower setting
or return to AUTO mode.
Recirculation is not available in the defrost mode, and
the air conditioning compressor cannot be turned off in
this mode.
For maximum side window defogging, turn the outboard
outlet thumbwheels to the side window defogger setting.
See ªVentilation Systemº later in this section for more
information on the outlet settings.
Rear Window Defogger
When the rear window defogger is turned on, the rear
window and both outside rearview mirrors are heated to
remove fog from the surface of the glass.
The rear window defogger
button is located on the
climate control panel to the
right of the defrost button.
Press the button to turn on the rear defogger. Press the
button again to turn the system off.
The system will automatically shut off after 10 minutes
unless your vehicle is traveling more than 30 mph
(48 km/h). If further defogging is desired once the
system is off, press the button again. The system will
automatically shut off after five minutes for any cycles
after the initial activation.
