Automatic Operation
This climate control system
automatically maintains the desired
temperature inside the vehicle.
Do not cover the sensor located on
the top of the instrument panel near
the windshield or the sensor grille
below the climate control faceplate.
These two sensors help regulate the
inside air temperature.
AUTO (Automatic Fan):Turn the
fan knob to AUTO for the system
to automatically adjust the fan
speed to reach the desired inside
temperature.
Temperature Control:Select
the desired cabin air temperature
between 60-90°F (16-32°C).
Choosing the coldest or warmest
temperature setting does not cause
the system to heat or cool any faster.AUTO (Automatic Air Delivery
Mode):Turn the air delivery mode
knob to AUTO for the system to
automatically control the direction
of the air ow to help reach the
desired inside temperature.
The system automatically controls
the air inlet to supply the outside
air or recirculated inside air needed
to heat or cool the vehicle faster.
The recirculation button indicator
light is lit whenever the recirculation
mode is on.
Press the outside air button to
change to outside air. However,
the recirculation mode may
turn back on automatically.
In cold weather, if the fan and air
delivery modes are in automatic,
the system starts at lower fan speeds
to avoid directing cold air into the
vehicle until warmer air is available.
The climate control system directs
air to the oor, but may automaticallychange modes as the vehicle
warms up to maintain the chosen
temperature setting. The length of
time needed to warm the interior
depends on the outside temperature
and inside temperature of the
vehicle.
Manual Operation
A(Fan Control):Turn clockwise
or counterclockwise to increase
or decrease the fan speed. To turn
the fan off, turn the left knob to
the
9position. In any setting other
than off, the fan runs continuously
with the ignition on. The fan must be
turned on to run the air conditioning
compressor. There will be some
air ow noticeable from the various
outlets when driving, even with the
fan in the off position. To turn off the
air completely, turn the fan to
9and
select the recirculation button.

Temperature Control:Turn
clockwise or counterclockwise
to increase or decrease the
temperature. Select the desired
cabin air temperature between
60-90°F (16-32°C). Typically, the
best setting is near 75°F (23°C).
Choosing the coldest or warmest
temperature setting does not cause
the system to heat or cool any
faster.
Air Delivery Mode Control:Turn
clockwise or counterclockwise
to change the current air ow mode.
Select from the following air
delivery modes:
H(Vent):Air is directed to the
instrument panel outlets.
)(Bi-Level):Air is divided
between the instrument panel
outlets and the oor outlets.
6(Floor):Air is directed to the
oor outlets with some air directed
to the windshield.
When this mode is selected, the
system turns the recirculation mode
off. Recirculation mode cannot be
selected while in oor mode. This is
to help prevent window fogging.
-(Defog):This mode clears
the windows of fog or moisture.
Air is directed to the oor outlets,
with some air directed to the
windshield and side window outlets.
In this mode, the system turns the
recirculation mode off and runs the
air conditioning compressor unless
the outside air is at or below freezing.
Recirculation mode cannot be
selected while in defog mode.
This helps prevent window fogging.
0(Defrost):This mode removes
fog or frost from the windshield
more quickly. Air is directed to the
windshield and the side window
outlets. In this mode, the system
turns the recirculation mode off
automatically and runs the air
conditioning compressor unless the
outside air is at or below freezing.
Recirculation mode cannot be
selected while in defrost mode.
This helps prevent window fogging.
For best results, clear all snow and
ice from the windshield before
defrosting.
#(Air Conditioning):Press to
turn the air conditioning system on
or off. An indicator light comes on to
show that the air conditioning is on.
The air conditioning can be selected
in any mode as long as the fan is on
and the outside temperature is above
freezing. A ashing indicator light
indicates that the air conditioning
compressor is currently not available.

On hot days, use the automatic fan
and automatic air delivery mode
settings and the vehicle will reach the
desired temperature more quickly.
The desired fan and air delivery
mode settings can still be adjusted
manually. Open the windows to let
the hot inside air escape, then close
them. This helps reduce the time it
takes for the vehicle to cool down
and helps the system to operate
more efficiently.
The air conditioning system removes
moisture from the air, so a small
amount of water might drip under the
vehicle while idling or after turning off
the engine.
;(Outside Air):Press to turn
the outside air mode on. An indicator
light comes on to show that outside
air is on. Air from outside the vehicle
will circulate throughout the vehicle.
The outside air mode can be used
with all modes, but it cannot be
used with the recirculation mode.
Pressing this button will cancel the
recirculation mode.
@(Recirculation):Press to
turn on the recirculation mode.
An indicator light comes on to show
that recirculation is on. This mode
recirculates and helps to quickly cool
or heat the air inside the vehicle.
It can be used to prevent outside air
and odors from entering the vehicle.
Avoid using the recirculation mode
during high periods of humidity
and cool outside temperatures
since this may result in increased
window fogging. If window fogging
is experienced, select the
defrost mode.
Recirculation mode is not available in
oor, defog or defrost modes and will
shut off automatically and change to
outside air. If the button is selected
in any of these modes, the indicator
will ash. This helps prevent window
fogging and moisture building up
inside the vehicle.Rear Window Defogger
The rear window defogger uses a
warming grid to remove fog from the
rear window.
The rear window defogger only
works when the ignition is in
ON/RUN.
<(Rear Window Defogger):
Press to turn the rear window
defogger on or off. An indicator light
on the button comes on to show
that it is activated.
The rear window defogger stays
on for approximately 10 minutes
after the button is pressed, unless
the ignition is turned to ACC/
ACCESSORY or LOCK/OFF.
If turned on again, the defogger only
runs for approximately ve minutes
before turning off. At higher vehicle
speeds, the defogger may stay on
continuously. The defogger can
also be turned off by turning off
the engine.
