Automatic Operation
Press the AUTO button when you want the system to
automatically adjust to changes in the temperature.
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 a display
of 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, fan speed and airflow direction
for a few seconds, and then it will display the
outside temperature.
In cold weather, the system will delay turning the fan on
high, to avoid blowing cold air. 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 FLOOR,
FLOOR
-MID, MID and WINDSHIELD-FLOOR. If the
system is set for AUTO, pressing the AIR FLOW button
will display the current airflow direction, the comfort
setting and the fan speed. 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 mid
-position. 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 to 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.
VENT: The VENT button allows outside air to flow
through your vehicle without the air conditioning
compressor working. Selecting the VENT and the
AUTO buttons at the same time allows the system to
control the air flow automatically without the use of the
air conditioning compressor or the use of the RECIRC
mode. To turn off the VENT selection, push the VENT
button again.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 for some other reason. RECIRC
and AUTO may be selected at the same time. The
system will remain in RECIRC until the ignition is
turned off. The system will return back to the previously
selected mode when the car is turned back on. RECIRC
can be selected in all manual airflow modes except
FRONT defrost. RECIRC cannot be selected with the
VENT button.
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.

Personal Choice Radio Controls
(If Equipped)
With this feature, your vehicle will recall the latest radio
settings as adjusted the last time your vehicle was
operated. This feature allows two different drivers to
store and recall their own radio settings for AM and FM
presets, last tuned station, volume, tone and audio
source (radio, cassette or CD). The settings recalled by
the radio are determined by which transmitter (ª1º or
ª2º) was used to enter the vehicle. The number on the
back of the transmitter corresponds to driver 1 or to
driver 2. After the unlock button is pressed on the
transmitter and the ignition is in RUN, the radio settings
will automatically adjust to where they were last set by
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 changes are made, the new settings will be
saved for that driver.
