Comfort Controls
This section tells you how to make your air system
work for you.
Climate Control Panel
Your vehicle is equipped with a dual-zone 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 altering the controls.
If your vehicle is equipped with the Climate Control
Personalization feature, you will be able to program
your preferred climate control settings by using your
remote keyless entry transmitter. See ªClimate Control
Personalizationº in the Index.
AUTO: The AUTO button will turn on the system
and automatically adjust the fan blower speed, air
delivery mode and temperature to your previously
programmed settings.
TEMP: This knob adjusts the air temperature coming
through the system. Turn the TEMP knob clockwise
to increase the temperature and counterclockwise to
decrease the temperature. You may also press the TEMP
knob to turn the system on and off. (You can turn the
comfort control system on by pressing any button on
the panel. The passenger's TEMP knob only turns off
the system of the passenger's side.) Once the system is
turned off, fresh air will continue to flow through the
vehicle, and the system will try to maintain the
previously set temperature.
Driver's Side Temperature Knob
You can control the temperature of the driver's side
independently from the passenger's side. Turn the driver's
side TEMP knob clockwise to increase the temperature
and counterclockwise to decrease the temperature.

3-3
Passenger's Side Temperature Knob
The right front passenger can control the temperature
of air for both the front passenger and rear seat area.
(The passenger's and driver's knob adjust from 60
F
(16
C) to 90
F (32
C) independent of each other.
It is suggested, however, that the passenger's setting
stay no more than four degrees warmer or cooler in
temperature from the driver's setting.) To turn the
system on, press the passenger's side TEMP knob.
Turn the passenger's side TEMP knob clockwise to
increase the temperature and counterclockwise to
decrease the temperature. Press the passenger's side
TEMP knob again to turn off the passenger's side
system. If the passenger's side is turned off, the driver's
side will control the temperature of the entire vehicle.
Automatic Operation
When the system is set for automatic operation, sensors
will control the air delivery mode. Air will come from
the floor, the instrument panel or windshield outlets.
The fan speed will vary as the system maintains the
selected temperature setting.Be careful not to put anything over the electronic solar
sensors located near the ends of the instrument panel
near the windshield. These sensors are used by the
automatic system to regulate temperature.
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 TEMP 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.
With the automatic setting, the air conditioning
compressor cycles when needed to cool the air.
In cold weather, when the system senses the need for
heat, the airflow will be directed out the floor outlets.
As the interior temperature approaches a desired setting,
the blower 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 air conditioning outlets (A/C mode) to maintain
comfort and prevent stuffiness.

3-4
If your vehicle is sitting out on a hot day and you have it
set on AUTO, the air will first flow out 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 air conditioning outlets.
To avoid blowing cold air in cold weather, the system
will start at reduced 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 coolant
warms up, the blower fan speed will gradually increase
and air will flow from the heater outlets, with some
airflow to the windshield to prevent fogging under most
normal conditions. If you select defrost mode or a
manual fan speed, this function will be skipped.
If you leave your vehicle, the system will remember
the control setting the next time you start your engine,
except for recirculation and defrost. Each ignition cycle
cancels recirculation. Defrost will change to automatic
operation when the ignition is shut off and then turned
back on.Manual Operation
You may manually adjust the air delivery mode, fan
speed, air input and compressor operation using the
following controls.
DEFROST (FRONT): 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.
RECIRCULATION: Press this button to limit
the amount of fresh air entering your vehicle. This is
helpful when you are trying to cool the air quickly or
limit odors entering your vehicle. In the AUTO mode,
the system will use recirculation as necessary to cool
the air. Pressing the recirculation button will change the
operation to a manual mode and the air will recirculate
non
-stop. Press this button again to turn off the
recirculation feature. If you notice the windows fogging,
press the recirculation button to exit the recirculation
mode. Recirculation is not available in the defrost mode.

3-5
A/C: Press this button to turn the air conditioning
compressor on and off. When you press the button,
an A/C OFF message appears on the climate control
panel's display. Press the button again and the air
conditioner will return to automatic control. The
system will cool and dehumidify the air inside the
vehicle. In the automatic mode, the air conditioning
compressor only operates when the system determines it
is needed. The A/C OFF function is not available in the
defrost mode.
MODE: Press this button (the right or left arrow)
to deliver air through the floor, instrument panel or
windshield outlets. The climate control system will
stay in the selected mode until the MODE button, the
DEFROST button or the AUTO button is pressed again.
Press the left or right arrow to cycle through the
following available modes.
UPPER: This setting directs airflow through
the middle instrument panel outlets. Your vehicle is
equipped with a driver's side lap cooler which will also
come on when the upper vents are being used.
BI-LEVEL: This setting directs air into your
vehicle in two ways. Cool air is directed to the upper
portion of your body through the four instrument panel
outlets while warmed air is directed to the floor.
DEFOG: This setting directs air to the floor
outlets and toward the windshield.
HEATER: This setting directs warmed air
through the floor outlets. Some warm air is diverted
to the windshield to minimize fogging.
FAN: The button with the fan symbol adjusts the
fan speed. Press the up arrow to increase fan speed and
the down arrow to decrease fan speed. Press the AUTO
button to set the fan speed for automatic operation.
If it is cold outside, the blower may not run in the
maximum high fan speed right away. The system
checks the temperature of the engine coolant to assure
it is warm enough to provide heat. When the engine
coolant is warm, the controller allows the fan to
gradually increase to a higher speed. This prevents cold
air from blowing into the passenger's compartment.
Selecting a manual fan speed will override this feature.
