dehumidify the air inside of your vehicle. You may
notice a slight change in engine performance
when the air conditioning compressor shuts off and
turns on again. This is normal.
Defogging and Defrosting
Fog on the inside of the windows is a result of
high humidity (moisture) condensing on the
cool window glass. This can be minimized if the
climate control system is used properly. There are
two modes to choose from to clear fog or frost
from your windshield. Use the defog mode to clear
the windows of fog or moisture and warm the
passengers. Use the defrost mode to remove fog
or frost from the windshield more quickly.
Turn the right knob to select one of the following
modes:
-(Defog):This mode directs the air to the oor
outlets, windshield and the side window outlets.
The air conditioning compressor will run
automatically to dehumidify the air to prevent
window fogging. The recirculation mode cannot be
selected while in the defog mode.
233

1(Defrost):This mode directs most of the air to
the windshield and the side window outlets, with
only a little air directed to the oor outlets. The air
conditioning compressor will run automatically
to dehumidify the air to prevent window fogging.
The recirculation mode cannot be selected while in
defrost mode.
Do not drive the vehicle until all the windows are
clear.
Rear Window Defogger
If your vehicle has this feature, the rear window
defogger uses a warming grid to remove fog from
the rear window.
If your vehicle has a sliding rear window, you will
not have a rear window defogger.
<(Rear):Press this button to turn the rear
window defogger on or off. An indicator light in the
button will come on to let you know that the
rear window defogger is activated. This button will
also activate the heated mirrors, if the vehicle
has them.The rear window defogger will automatically turn
off several minutes after the button is pressed.
Pressing the button while the defogger is running
can also turn off the defogger.
W(Mirror):If your vehicle does not have a rear
defogger and has heated mirrors, your vehicle
will have this button to activate the heated mirrors.
Notice:Do not use anything sharp on the
inside of the rear window. If you do, you could
cut or damage the warming grid, and the
repairs would not be covered by your warranty.
Do not attach a temporary vehicle license,
tape, a decal or anything similar to the
defogger grid.
234

If you select recirculation while in defrost, defog,
or oor, the light in the button will ash and then go
out to let you know that this is not allowed. This
is normal and helps to prevent fogging.
When the weather is cool or damp, operating the
system in recirculation for extended periods of
time may cause fogging of the vehicle’s windows.
To clear the fog, select either defog or front
defrost.
You may also notice that the air condition
compressor will run while in recirculation mode.
This is normal and helps to prevent fogging.
9(Off):Press this button to turn off the entire
climate control system. Outside air will still
enter the vehicle, and will be directed to the oor.
This direction can be changed by pressing the
mode button. The temperature can also be
adjusted using either temperature knob. Press the
up or down arrows on the fan switch, the defrost
button, the AUTO button, or the air conditioning
button to turn the system on when it is off.
Display
If you press the mode button to select an air
delivery mode, the display will change to show you
the selected air delivery mode. After ten seconds,
the display will change to show the driver
temperature setting and the selected mode.
If you press the up or down arrows on the fan
switch, the display will change to show the
selected fan speed. After ten seconds, the display
will change to show the driver temperature
setting and the selected mode.
Whenever you press AUTO, the display will
change to show the following:
The current driver’s set temperature and an
arrow for ve seconds

Air Conditioning
#
(Air Conditioning):Press this button to turn
the air conditioning (A/C) compressor on and
off. The snowake symbol will appear on
the display when the A/C is on and will turn off
when the air conditioning is off.
Pressing this button when the outside temperature
is too cool for air conditioning will make the
snowake symbol ash three times and then turn
off to let you know the air conditioning mode is
not available. If the air conditioning is on and the
outside temperature drops below a temperature
which is too cool for air conditioning to be effective,
the snowake symbol will turn off to let you
know the air conditioning mode has been
canceled.
When air conditioning is selected or in AUTO
mode, the system will run the air conditioning
automatically to cool and dehumidify the air
entering the vehicle. If you select A/C off while in
front defrost, defog or recirculation, the A/C
snowake symbol will turn off, but the A/C
compressor will still run to help prevent fogging.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.
On cool, but sunny days while using manual
operation of the automatic system, use bi-level to
deliver warm air to the oor and cooler air to
the instrument panel outlets. To warm or cool the
air delivered, turn the temperature knob to the
desired setting.
In AUTO mode the system will cool and dehumidify
the air inside the vehicle. Also while in AUTO
mode, the system will maximize its performance
by using recirculation as necessary.
240

In order to prevent false temperature readings at
startup, the displayed temperature will not
change until the following occurs:
Vehicle speed is above 10 mph (16 kmh) for
5 minutes.
Vehicle speed is above 32 mph (51 kmh) for
2 and a half minutes.
The climate control system uses the information
from these sensors to maintain your comfort
setting by adjusting the outlet temperature, fan
speed, and the air delivery mode. The system may
also supply cooler air to the side of the vehicle
facing the sun. The recirculation mode will also be
used as needed to maintain cool outlet
temperatures.
Defogging and Defrosting
You can use either defog or front defrost to clear
fog or frost from your windshield. Use the
defog mode to clear the windows of fog or
moisture. Use the front defrost button to defrost
the front windshield.
-(Defog):Use this setting to clear the windows
of fog or moisture. Press the mode button to
select this setting. This setting will deliver air to
the oor and windshield outlets.
0(Front Defrost):Press the front defrost button
to defrost the windshield. The system will
automatically control the fan speed if you select
defrost from AUTO mode. If the outside
temperature is 40°F (4°C) or warmer, your air
conditioning compressor will automatically run to
help dehumidify the air and dry the windshield.
