Automatic operation
Press AUTO and select the desired
temperature. The system will either
heat or cool the vehicle to achieve
the selected temperature. The
system will automatically determine
fan speed, airflow location and
whether outside or recirculated air
is required.
When in automatic operation and
weather conditions require heat, the
air will be sent to the floor ducts.
However, until the engine is warmed, the fan speed will operate at a low
speed and airflow will be directed to the windshield defroster ducts.
Upon engine warm up, the system will automatically direct airflow to the
floor ducts and operate at the required fan speed to achieve the selected
temperature.
If unusual conditions exist (i.e. window fogging, etc.), the manual
overrides allow you to select airflow locations and fan speed. To return
to automatic operation after an airflow selection, press AUTO.
Single/dual temperature zone
Press DUAL to enable or disable the
dual zone temperature feature.
When DUAL is pressed, the display
window indicates the current
temperature setting for the driver
and the last temperature setting for
the passenger. In addition to the
DUAL control, the passenger may
manually enable the dual zone
temperature feature by pressing the
passenger temperature control.
The DUAL indicator will be lit when the dual zone temperature feature is
selected.
Driver/passenger temperature selection
To control the temperature, select the desired temperature by pressing
the driver/passenger temperature controls.

Temperature conversion
Press the Fahrenheit/Celsius (°F /°C)
control to switch between Fahrenheit
and Celsius.
Displaying outside temperature
Press Ext to display the outside
temperature. The outside
temperature will be displayed until
Ext has been pressed again.
If the interior temperature or fan speed are adjusted or a manual
override is selected while the outside temperature is being displayed, the
new temperature, fan speed or override control will appear in the display
window for four seconds, the outside temperature will then return to the
display window.
The outside temperature reading is most accurate when the vehicle is
moving. Higher temperature readings may be displayed when the vehicle
is not moving. Due to locations, the outside temperature readings from
the vehicle may not agree with those obtained from the radio station
broadcasts.

Fan speed ()
When in automatic operation, fan
speed operates as necessary to
achieve the selected temperature. If
desired, the fan speed can be
adjusted manually through the use
of the fan speed control.
•A/C control
A/C(air conditioning) — Used to
manually enable or disable air
conditioning in all modes except
Defrost. The A/C will only function
if the outside temperature is above
approximately 2°C (35°F). In
Defrost, the A/C will operate
automatically if the outside
temperature is above approximately
2°C (35°F). However, the A/C indicator will not be lit in Defrost mode.
In automatic operation, the air conditioning operates as necessary to
achieve the selected temperature and the A/C indicator will be lit if the
outside temperature is above approximately 2°C (35°F). You may
override the automatic A/C operation at any time. To manually control
the A/C operation and cancel automatic A/C operation, press the A/C
control. When the air conditioning is manually controlled in automatic
operation, the AUTO indicator will remain lit. To return to automatic air
conditioning operation, press AUTO.
Since the air conditioner removes moisture from the air, it is considered
normal operation if clear water drips on the ground under the air
conditioner drain.

•Recirculated air
(recirculated air) — Used to
manually enable or disable the
operation of recirculated air in all
modes except Defrost. When the air
conditioning is operating,
recirculated air helps to reduce the
amount of time required to cool the
inside of the vehicle. Recirculated
air will reduce undesirable odors
from entering the vehicle.
Recirculated air cannot be selected in Defrost, as interior fogging may
occur. In Floor and Floor and Defrost modes, the recirculated air control
can be enabled. However, to reduce the risk of fogging, the recirculated
air button will be disabled in approximately 4 minutes.
In automatic operation, the recirculated air operates automatically as
necessary to achieve the selected temperature. If desired, recirculated
air can be controlled manually through the use of the recirculated air
control. When recirculated air is controlled while in automatic operation,
the AUTO indicator will remain lit and the system will remain in
automatic operation. To return to automatic recirculated air, press
AUTO.
Under cold or dampconditions, do not leave the climate control system
in recirculated air for extended periods of time as this may cause interior
fogging of the windows.
Manual override controls
The manual override controls allow you to determine where airflow is
directed. To return to full automatic control, press AUTO.

•Off-Outside air is shut out and the fan will not operate. This mode will
reduce undesirable odors from entering the vehicle but may increase
the possibility of interior window fogging.
•Panel - Distributes outside or recirculated air through the instrument
panel registers. The A/C compressor will only function if the outside
temperature is above approximately 2°C (35°F). The system will allow
some airflow through the floor ducts.
•Panel and Floor -Distributes outside or recirculated air through the
instrument panel registers and floor ducts. The A/C compressor will
only function if the outside temperature is above approximately 2°C
(35°F). The air distributed through the floor ducts will be slightly
warmer than that sent to the instrument panel registers.
•Floor -Distributes outside or recirculated air through the floor ducts.
The A/C compressor will only function if the outside temperature is
above approximately 2°C (35°F).
•Floor & Defrost -Distributes outside or recirculated air through the
floor ducts, windshield defroster ducts and the side window demisters.
The A/C compressor will operate automatically if the outside
temperature is above approximately 2°C (35°F). The air distributed
through the floor ducts will be slightly warmer than that sent to the
windshield defroster ducts and the side window demisters.
•Defrost-Distributes outside air through the windshield defroster ducts
and the side window demisters. The A/C compressor will operate
automatically if the outside temperature is above approximately 2°C
(35°F). This mode will clear ice and fog from the windshield.
Operating tips
•To reduce fogging in humid weather, place the climate control system
in Defrost mode and Rear Defrost before driving.
•To reduce humidity buildupinside the vehicle in warm weather
conditions, don’t drive with the climate control system in the Off
mode.
•To reduce humidity buildupinside the vehicle in cold weather
conditions, don’t drive with the climate control system in recirculation
mode or Off mode.
•Remove any snow, ice or leaves from the exterior base of the

•Do not place objects under the front seat or over the defroster ducts.
They may reduce visibility, fall into the ducts, or degrade the
performance of your climate control system.
Do not place objects on top of the instrument panel, as these
objects may become projectiles in a collision or sudden stop.
AUXILIARY CLIMATE CONTROLS
The auxiliary climate control feature provides increased capacity to
quickly heat or cool the vehicle. The auxiliary climate controls are
located in the overhead console of the first row seating and in the floor
console of the second row seating.
The auxiliary climate controls are independent of the main climate
control system. If the main climate control system is in the Off position,
the auxiliary climate controls will still operate. However, if the main
climate control system is ON, the auxiliary air will not be cooled unless
the air conditioning is functioning on the main climate control system.
The auxiliary unit can be
controlled either by the front
seat passengers using the front
auxiliary control or by the rear
seat passengers using the rear
auxiliary control, but not both.
To control the auxiliary unit using the rear control, the front
