Comfort Controls
This section tells you how to make your air system
work for you.
With the climate control 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.
Climate Control Panel
Fan Switch
!~
(Fan): The switch with the fan symbol adjusts the
fan speed. Press the up arrow to increase fan speed and
the down arrow to decrease fan speed.Driver's Side Temperature Knob
The TEMP/AUTO knob adjusts the air temperature
coming through the system. Turn the TEMP/AUTO
knob clockwise to increase the temperature and
counterclockwise to decrease the temperature.
Press the TEMP/AUTO knob to put the system
in the automatic mode.
Passenger's Side Temperature Switch
With this dual
-zone feature, the right front passenger
can control the temperature of air for his/her own zone.
The passenger can select a temperature that is up to
four degrees warmer or cooler than the driver's setting.
To turn the system on, press the PASS/TEMP switch.
Press the up arrow to increase the temperature and press
the down arrow to decrease it. Pressing the OFF button
will turn off the dual
-zone function.
Outside Temperature Display
The outside temperature is always displayed when your
vehicle is running. You can change it from Fahrenheit
to Celsius with the Driver Information Center (DIC).
Pressing the SKIP INFO button (above the radio) until
ENGLISH/METRIC RESET is displayed. Then press
the NO INFO RESET button to select.

3-3
The outside temperature sensor is located near the front
grille. The sensor can be affected by road or engine
heat during idling, slow driving or when the engine is
first started after a short trip. In order to ensure proper
automatic climate control operation, the outside air
temperature display may not update as quickly as
expected. This is to allow the air surrounding the outside
temperature sensor to be as close to the actual outside
conditions as possible. This is determined by how much
time has elapsed since the vehicle has been turned off
and by vehicle speed.
Mode Switch
Press the MODE switch to deliver air through the floor,
middle or windshield outlets. The system will stay in
the selected mode until the MODE switch is pressed
again. Press the up or down arrow to cycle through
the available modes.Manual Operation
You may manually adjust the air delivery mode or
fan speed.
(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.
Heater/Defrost): 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.
(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.

3-4
!~(Fan): Press the switch with the fan symbol on it
until AUTO is displayed on the screen. This setting
automatically controls the fan speed. If it is cold outside,
the fan may not run in the maximum 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 compartment. If you
want the fan at a higher speed, press the up arrow until
you see HI on the display. If you want the fan speed to
be automatic, but you want the fan speed to be higher
than the AUTO setting, press the fan symbol until
HI AUTO is shown on the display. If you want the
fan at a lower speed, press the down arrow until LO is
shown on the display. If you want the fan speed to run
lower than the AUTO setting, press the switch until
LO AUTO is shown on the display.OFF: Press this button to turn the system off.
Fresh air will continue to flow through the vehicle,
and the system will try to maintain the previously set
temperature. The outside temperature will show on the
display when the system is OFF.
AC (Air Conditioning): Press this button to turn the
air conditioning on and off. The system will cool and
dehumidify the air inside the vehicle. In the AUTO
mode, the display will show that AC is active, but the
air conditioning compressor only operates when the
system determines it is needed.
(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. 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.

3-5
Automatic Operation
When the system is set for automatic operation,
sensors will control the air delivery mode. Air will
come from the floor, middle or windshield outlets.
The fan speed will vary as the system maintains the
selected temperature setting.
Be careful not to put anything over the solar sensor
located in the middle of the instrument panel near the
windshield. This sensor is 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/AUTO 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 the
temperature of 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 automatically cycles when needed to cool
the air. 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 a
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 air conditioning outlets (AC mode) to
maintain comfort and prevent stuffiness.
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 air outlets for a few seconds. That is normal.
This is to expel hot air from the air outlets. As the
air is cooled, the airflow will move through the air
conditioning outlets. If you start your vehicle with the
fan setting on HI, it will skip the air conditioning purge.

3-6
To avoid blowing cold air in cold weather, the system
will delay turning on the fan until warm air is available.
The length of delay depends on the outside air
temperature, engine coolant temperature or the
time since the engine was last started. As the coolant
warms up, the fan speed will gradually increase and
air will flow from the floor outlets, with some airflow
to the windshield to prevent fogging under most
normal conditions.
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, whereas, defrost mode will change
to automatic operation when the ignition is shut off and
then turned back on.Electronic Solar Sensor
The sensor monitors the sun's solar radiation and
is located on top of the instrument panel near the
windshield. The electronic climate control panel uses
this information to automatically make the necessary
temperature and airflow adjustments to maintain
your comfort.

3-7 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 AC button or the TEMP/AUTO knob to turn
the system on and then select the proper mode to direct
airflow. The system will cool and dehumidify the air
inside the vehicle. Also while in the AUTO mode, the
system will use recirculation as necessary to cool the air.
You may also need to adjust the interior temperature and
the fan speed as needed.
When the air conditioner is on, you may sometimes
notice slight changes in your vehicle's engine speed
and power. This is normal because the system is
designed to cycle the compressor on and off to
maintain the desired temperature.
Heating
Press the MODE switch to select the heater mode.
Adjust the interior temperature to a comfortable level
and if the fan speed needs adjusting, press the up or
down arrow.
Outside air will be brought in and sent through the floor,
air conditioning or bi
-level outlets (depending on the
condition). The heater works best if you keep your
windows closed while using it.
Defogging and Defrosting
Use defrost to remove fog or ice from the windshield
quickly in extremely humid or cold conditions.
Press the MODE switch. If you select defrost mode,
adjust the fan speed by pressing the fan switch up or
down. If you select defrost mode from AUTO, the
system will control the fan speed. The temperature also
needs to be adjusted by turning the TEMP/AUTO knob.
Recirculation is not available in the defrost or defog modes.

3-8 Rear Window Defogger
The lines you see on the rear window warm the glass.
When the rear window defogger is turned on, the rear
window and both outside rearview mirrors are heated to
remove ice and snow from the surface of the glass.
Press this button to
turn on the rear defogger.
The system will automatically shut off after 10 minutes.
If further defogging is desired, press the button again.
Do not attach a temporary vehicle license, tape or decals
across the defogger grid on the rear window.
NOTICE:
Don't use a razor blade or something else sharp
on the inside of the rear window. If you do, you
could cut or damage the warming grid or the
integrated rear window antenna, and the repairs
wouldn't be covered by your warranty.
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 running.
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 lever located
on each side of the outlets downward.
