FAN SPEED: Press the button with the fan symbol
on it to manually lock in the current fan speed and to
stop the automatic fan speed control. Pressing the
arrows will delete AUTO from the digital display. The
fan graphics with the fan speed bars will be shown. To
increase the fan speed so that more air flows into the
vehicle, press the UP arrow on the fan switch. To
decrease the fan speed and airflow, press the DOWN
arrow. The AUTO button must be pressed to return to
the automatic fan control.
MODE: Press the MODE button to manually lock in
the current air delivery setting and to stop the automatic
mode control. Pressing the MODE button will delete
AUTO from the digital display and the mode graphics
will be shown. To change the setting, press the MODE
button again. The AUTO button must be pressed to
return to the automatic mode selection.
UPPER: This setting directs most of the air
through the instrument panel outlets and a very small
amount to the lower outlets.
BI-LEVEL: This setting directs air into the
vehicle in two ways. Cooler air is directed toward your
upper body through the instrument panel outlets, while
warmer air is directed through the lower outlets.
LOWER: This setting directs most of the air to
the floor area and some of it toward the windshield and
side window vents.
DEFOG: This setting divides the air between
the windshield and lower outlets and a small amount
toward the side window vents. This is useful when fog
appears on the windshield or side glass due to rain or
snowy conditions.
Function Buttons
These buttons control climate control ON/OFF, air
intake, front defrost, rear defrost and the air
conditioning operation.
OFF: Press the OFF button to turn off the climate
control system. This is the only setting that fully shuts
off the fan. The digital display will show only the
outside temperature. You can still adjust the driver set
temperature, the passenger temperature offset and the
air intake mode while in OFF.

3-8
A/C: This button turns the air conditioning
compressor off or on under most conditions. The light
on the A/C button will come on when the compressor is
operating in either the automatic or manual mode. The
air conditioning does not operate at temperatures below
approximately 35
F to 40
D (2
C to 4
C).
The light on the A/C button will flash if pressed when
air conditioning is not allowed. The air conditioning
cools and dehumidifies the air coming into the vehicle.
The air conditioning cannot be turned off in DEFROST
and DEFOG, as it helps to remove moisture from the
vehicle. It also helps to keep the windows clear.
If the system is operating in the AUTO mode, turning
the air conditioning off will delete AUTO from the
digital display and show current mode and fan settings.
The AUTO button must be pressed to return to the
automatic mode operation.
The air conditioning may be forced off at high engine
speeds or high engine oil or coolant temperatures. FRESH AIR: Press this button to provide fresh
air from the outside. The light on this air intake button
will come on to show when it is operating. When in the
AUTO mode, the system automatically selects FRESH
AIR instead of recirculate, as required, to control the
temperature in the vehicle. By pressing FRESH AIR, the
system will lock into the fresh air mode. Any adjustment
to the air intake must then be made manually. FRESH
AIR should be used when trying to defrost or defog
windows to help reduce moisture inside the vehicle.
RECIRCULATE: Press this button to limit the
amount of fresh air entering the vehicle. The light on
this air intake button will come on to show when it is
operating. Recirculate is helpful when you are trying to
cool the air quickly or trying to limit odors and dust
from entering the vehicle. When in the AUTO mode,
the system automatically selects recirculate to cool the
vehicle's temperature. By pressing this button, the
system will lock into the recirculated air mode.
Any adjustment to the air intake must then be made
manually. The recirculated air mode is not allowed in
the front defrost or defog modes as fresh air helps
reduce moisture inside the vehicle.

3-9
Operating the system in the recirculation mode may
cause fogging of the vehicle's windows when the
weather is cold and damp. To clear the fog, switch the
system to either the DEFOG or DEFROST mode and
increase the fan speed. To avoid re
-fogging of the
windows, operate the system in the OUTSIDE
AIR mode.
FRONT: Press the FRONT defrost button to
quickly remove fog or frost from the windshield. This
setting directs most of the airflow to the windshield and
a small amount toward the lower and side window
outlets. The light on the button will come on and the
digital display will show the defrost mode symbol and
fan speed when the front defrost mode is being used.
Pressing FRONT defrost again will return the system to
the last operating mode and the air intake mode will be
in FRESH AIR.
If the system is in FRONT defrost when you shut the
engine off, it will restart in FRONT defrost unless the
engine is off for longer than 40 minutes. If the engine is
off longer than 40 minutes, the system will restart in the
operating mode you had set prior to FRONT defrost and
the air intake mode will be in FRESH AIR.
See ªRear Window Defoggerº later in this section for
more information.
Sensors
The automatic electronic dual climate control system
uses several sensors to control operation and
display information.
Solar Load Sensor
This sensor is located on the top right side of the
defroster grille. The defroster grille is on the top of the
instrument panel.
The sensor monitors the sun's solar radiation and uses
this information as part of the automatic climate control
system when operating in the AUTO mode.
Be careful not to put anything over the sensor. When
covered, the sensor cannot compensate for changes in
the amount of heat the vehicle is absorbing from the sun.
Outside Air Temperature Sensor
This sensor is located in the air intake under the front
bumper of the vehicle. Information from this sensor is
used for the outside air temperature readings shown
on the digital display for the automatic climate
control system.

3-10
If the outside temperature goes up, the displayed
temperature will not change until:

The vehicle's speed is above 16 mph (26 km/h) for
one and a half minutes.

The vehicle's speed is above 45 mph (72 km/h) for
one minute.
These delays help prevent false readings. If the
temperature goes down, the outside temperature display
is updated immediately.
If the vehicle has been turned off for more than three
hours, the current outside temperature will be shown
when you start the vehicle. If it has been turned off for
less than three hours, the temperature will be recalled
from the previous vehicle operation.
Inside Temperature Sensor
This sensor is located to the left of the ignition switch.
The automatic climate control system uses this sensor to
receive information, so if you block or cover it, the
system will not function properly.Air Conditioning
On very hot days, the vehicle will cool down more
quickly and economically if you open the windows
long enough to let hot inside air escape. Then keep the
windows closed in order to allow the air conditioning to
work best. Maximum cooling will occur when the
recirculate setting is operating, airflow direction is in the
upper mode, and the temperature control knob (on a
manual climate control system) is turned all the way to
the blue area. These settings will be selected by the
automatic electronic dual climate control system if
operating in AUTO when maximum cooling is required.
When the air conditioning is on, you may sometimes
notice slight changes in the vehicle's engine
performance and power. This is normal. The system is
designed to help fuel economy while maintaining the
desired cooling level.
The air conditioning removes moisture from the air, so
you may notice water dripping from under the vehicle
when it is idling or after it has been turned off.
This is normal.
