Comfort Controls
This section describes how to operate your climate
control system. Your climate control system uses
ozone
-friendly air conditioning refrigerant.
With these systems, 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.
Personal Choice Comfort Controls
(If Equipped)
This feature allows two different drivers to store and
recall their own climate control settings for temperature,
air delivery mode, fan and passenger climate control
(on/off) status. The personal choice settings recalled are
determined by the transmitter used to enter the vehicle.
After the button with the unlock symbol on a remote
keyless entry transmitter is pressed, and the ignition is in
RUN, the climate control will adjust to the last settings
of the identified driver. The settings can also be changed
by pressing one of the MEMORY buttons (1 or 2)
located on the driver's door, until you hear two beeps.
When adjustments are made, the new settings are
automatically saved for that driver.
Electronic Touch Climate Control
If your vehicle has this climate control system, the
following information tells you how it works.
Fan Lever
The FAN control is used to select the speed of the
blower fan and the force of air you want. Moving the
lever between LOW and HIGH will decrease or increase
the fan speed. The fan will be off when the system is off.

3-3
Temperature Lever
This lever adjusts the temperature of the air coming
through the system. Move the TEMPERATURE lever to
change the temperature of the air coming through your
outlets. Move the lever between COOL and WARM to
lower or raise the temperature.
Mode Controls
The buttons on your system allow you to choose
settings to deliver air through the lower, middle or
windshield outlets.
RECIRC: Press this button to limit the amount of
outside air entering your vehicle. This is helpful when
you are trying to cool the interior of the vehicle quickly,
or limit the amount of outside air entering your vehicle.
To turn off RECIRC, press the button again. If you
select FRONT defrost or BLEND while RECIRC is
selected, the system will automatically turn off RECIRC
to prevent fogging. If you select RECIRC while in
FRONT defrost, the RECIRC light will flash three times
to let you know this is not allowed.VENT: This setting directs outside air through the
middle instrument panel outlets. The air conditioning
compressor is not working when VENT is selected.
If you select VENT while in FRONT defrost, the VENT
light will flash three times to let you know this is not
allowed. This is to prevent fogging.
HTR: This button directs air out of the heater outlets.
Most of the air will come from the floor outlets while
some air will flow through the windshield and side
window outlets. The air conditioning compressor is not
working when HTR is selected.
BLEND: When BLEND is selected, the airflow will
be split between the windshield and the floor outlets.
The air conditioning compressor will be operating.
FRONT: This setting directs most of the airflow toward
the windshield.
OFF: The ventilation system always allows fresh
air to flow through your vehicle when it is moving.
The system will try to keep the air at a previously
chosen temperature. When the system is off, the
blower fan is also off.

3-4
MAX: This setting directs airflow through the middle
instrument panel outlets. The amount of outside air
entering your vehicle is limited with this setting. The air
conditioning compressor is on in this mode.
Also in this mode, the RECIRC function is activated to
create the maximum cooling effect in the vehicle. If
RECIRC was active before selecting MAX, the light in
the RECIRC button will go off. If RECIRC is selected
after MAX, the light in the RECIRC button will not
come on.
NORM: This setting cools the outside air entering your
vehicle and directs it through the middle instrument
panel outlets. The air conditioning compressor is on in
this mode.
BI
-LEV: This setting directs warm air to the floor and
cooler air to the middle instrument panel outlets. The air
conditioning compressor is on in this mode.
Dual Automatic ComforTemp

Climate Control (If Equipped)
If your vehicle is equipped with the Dual Automatic
ComforTemp Climate Control system, the following
information tells you how it works.
You will hear a beep each time a button is pushed and a
light on the button will indicate which function is active.
The lights are on all buttons except TEMP, FAN and
AIR FLOW. The display will show fan speed, comfort
level setting and airflow direction for a few seconds
whenever AUTO is selected, and then it will display the
outside temperature. The outside temperature reading is
most accurate when the vehicle is moving. During stops,
the display shows the previous temperature for best
accuracy and system control.

3-5
Sun and temperature sensors automatically adjust the air
temperature, the airflow direction and the fan speed to
maintain your comfort setting. The system may supply
cooler air to the side of the vehicle toward the sun.
Be careful not to put anything over the sensor on top
of the dash.
Temperature Button
To adjust the comfort level you want maintained inside
the vehicle, push the TEMP button. If you want a
warmer comfort level, push the up arrow. If you want
a cooler comfort level, push the down arrow. Your
comfort setting is shown in the display. The display
will then return to the outside temperature.
Fan Button
The speed of the blower fan is controlled automatically
if you have the system set for AUTO. Pressing the
FAN button will display and hold the current blower
fan setting.
If you want the blower fan to run at a lower speed, push
the bottom of the FAN button. The fan speed will
decrease with every push of the button until the lowest
speed is reached. If you want to increase the fan speed,
push the top of the FAN button. Notice the fan
indicators in the display.Mode Controls
Press the AIR FLOW button to deliver air through the
floor, middle or windshield outlets. The system will stay
in the selected mode until the AUTO button is pushed.
Use the up and down arrows on the AIR FLOW button
to cycle through the available modes.
Automatic Operation
Press the AUTO button when you want the system to
automatically adjust to changes in the temperature inside
the vehicle, the outside temperature and the sun load on
the vehicle. When the system is set for automatic
operation, air will come from the floor, middle or
windshield outlets depending on the temperature inside
the vehicle, the outside temperature and sun load. Fan
speed will vary as the system gets to and maintains the
comfort setting you have selected through the use of the
TEMP button.
To find your comfort setting, start with the system in
AUTO mode and the TEMP button adjusted to 75
F
(24
C), give the vehicle about 20 minutes to stabilize,
and adjust your comfort setting if necessary, by using
the TEMP button. The display will show the comfort
setting for a few seconds and then it will display the
outside temperature. If you want to see your current
automatic fan speed, airflow direction and comfort
setting, press the AUTO button.

3-6
In cold weather, the system will delay turning on the
fan, to avoid blowing cold air. During this delay the
system will be in FRONT defrost mode and the light in
the button will come on and stay on as long as the
display is showing the current mode, set TEMP and
FAN speed. This light will go off when the display
returns to the outside temperature. The length of the
delay depends on the engine coolant temperature and the
outside temperature. Pushing the FAN, AIR FLOW or
FRONT buttons will override this delay, turn off the
AUTO setting and change the fan speed.
Manual Operation
You may also manually adjust the air delivery or
fan speed.
AIR FLOW: This button is used to change the
direction of the airflow. The airflow choices available
are WINDSHIELD
-FLOOR, MID, MID-FLOOR, and
FLOOR. If the system is set for AUTO, pressing the
AIR FLOW button will display and hold the current
airflow direction and the comfort setting. Press the AIR
FLOW up or down button again to change the direction
of the airflow.If the AIR FLOW up button is selected while in the
FRONT defrost mode, the system will direct the air
toward the windshield and the floor. If the AIR FLOW
down button is selected while in the FRONT defrost
mode, the system will direct the air toward the floor, and
the FRONT defrost mode will cancel. Notice the arrows
in the display.
OFF: If the passenger comfort control is turned on,
it can be turned off by pressing the OFF button once.
Pressing the OFF button a second time will turn off the
main system. Turning off the main system causes the fan
to turn off and the airflow to be directed toward the
floor. The system will still try to keep the interior of the
vehicle at the previous chosen comfort setting. The
outside temperature will show on the display when the
system is OFF.
The ventilation system always allows fresh air to flow
through your vehicle when the vehicle is moving even
with the system in the OFF mode.

3-7
VENT: The VENT button allows outside air to flow
through your vehicle without the air conditioning
compressor working. Selecting VENT and the AUTO
button at the same time allows the system to control
automatically without the use of the RECIRC mode.
To turn off the VENT selection, push the VENT button
again. If you select VENT while in FRONT defrost, the
VENT light will flash three times to let you know this is
not allowed. This is to prevent fogging.
RECIRC: When RECIRC is selected, the system will
limit the amount of outside air entering your vehicle.
This is helpful when you are trying to cool the interior
of the vehicle quickly or limit the amount of outside air
entering your vehicle. RECIRC and AUTO may be
selected at the same time. The system will remain in
RECIRC until the ignition is turned off, then the system
will return back to the previously selected mode.
Deselecting the RECIRC button will also turn off the
RECIRC function. RECIRC can be selected in all
manual airflow modes except FRONT defrost and
VENT. If you select RECIRC while in FRONT defrost,
the RECIRC light will flash three times to let you know
this is not allowed. This is to prevent fogging.FRONT: This selection is used to defrost the windshield
by directing the airflow toward the windshield.
If FRONT is selected while in the AUTO mode, the
fan speed and the air temperature from the front
defroster will vary. If a manual fan speed setting is
selected, the fan speed will remain at that selection
until another fan speed selection is made or the
AUTO mode is selected. To turn off FRONT, press
the AUTO or AIR FLOW button.
FRONT defrost will work better if any ice or snow is
cleared from the hood and the air inlet area between the
base of the windshield and the hood.

3-8 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.
If you have the electronic touch system, for quick
cool
-down on very hot days, use MAX with the
temperature and fan speed adjusted to COOL and
HIGH. If this setting is used for long periods of time,
the air in your vehicle may become too cold and dry.
For normal cooling on hot days, use NORM and adjust
the temperature and fan speed for your comfort. If
RECIRC is selected while in the NORM air
conditioning mode, the system works like MAX and
recirculates the air.On sunny days, when the air is moderately warm or
cool, use BI
-LEV to deliver warm air to the floor and
cooler air to the middle instrument panel outlets. On
days like these, the sun may adequately warm your
upper body, but your lower body may not be warm
enough. To warm or cool the air delivered, adjust the
TEMPERATURE lever.
The amount of fresh air entering the vehicle is limited
when RECIRC is selected. This is helpful when you are
trying to cool the air in your vehicle or limit the air
entering the vehicle.
If your vehicle has the Dual Automatic ComforTemp

system and it is set for AUTO, on very hot days, the
system will automatically enter the RECIRC mode and
the temperature door will be positioned at the full cold
position for maximum cooling. If the system is not in
the AUTO mode, RECIRC should be selected to provide
maximum cooling. You can choose the extreme comfort
setting of 60
F (16
C), but the system will not cool any
faster by choosing the extreme comfort setting.

3-9 Heating
If your vehicle has the electronic touch system, on
cold days, use HTR with the TEMPERATURE lever
toward WARM.
If your vehicle has the Dual Automatic ComforTemp
system, and on cold days, if the AUTO mode is selected,
the system will automatically direct the air toward the
floor and the temperature door will be positioned at the
full hot position. You can choose the extreme comfort
setting of 90
F (32
C) but the system will not warm
up any faster by selecting the extreme comfort setting.
If the outside temperature is cold, the fan will be
delayed to avoid blowing cold air. Pushing the FAN,
AIR FLOW or FRONT buttons will override this delay,
turn off the AUTO mode and change the fan speed.
With each system, 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.
Defogging and Defrosting
If you have the electronic touch system, adjust the
TEMPERATURE lever toward WARM and the FAN
lever toward HIGH.
If you have the Dual Automatic ComforTemp system,
use the FRONT button to defog or defrost the
windshield. By choosing this button, the airflow will be
directed at the windshield. Adjust your comfort level by
pressing the TEMP up or down arrow. The fan speed
will be controlled by the system. You can change the fan
speed by pressing the top of the FAN button to increase
speed, and the bottom of the button to decrease speed.
To reduce the chance of fogging your windows in cold
weather, using the electronic touch system, select HTR
to supply air through the floor outlets. Then move the
FAN lever to HIGH for a few moments before driving
away. This will blow moist air from the intake outlets
toward the floor, not the windshield. If you have the
Dual Automatic ComforTemp system, the AUTO setting
will do this for you. Manual operation of the automatic
ComforTemp system in the FLOOR mode will also
supply air through the floor outlets.
