Comfort Controls
Dual ComforTemp Climate Control
With this system, the driver and passenger can maintain
separate temperatures. The system works best if you
keep your windows closed while using it.
Fan Control Knob
The left knob labeled FAN controls the fan speed selection.
If the airflow seems very low when the fan is adjusted
to the highest setting regardless of the mode setting,
your passenger compartment air filter may need to be
replaced. See ªMaintenance Scheduleº or ªPassenger
Compartment Air Filterº in the Index.Driver's Temperature Lever
The lever on the left adjusts the air temperature on the
driver's side outlets independent of the temperature set by
the passenger. Slide the lever up to raise the temperature.
Slide the lever down to lower the temperature.
Passenger's Temperature Lever
The lever on the right adjusts the air temperature on the
passenger's side independent of the temperature set by
the driver. Slide the lever up to raise the temperature.
Slide the lever down to lower the temperature.
Mode Knob
The right knob has several settings to control the
direction of airflow. To access the various modes
available, turn the mode knob to the desired mode.
MAX: This setting recirculates much of the air inside
your vehicle and sends it through the instrument
panel outlets. The air conditioning compressor will
run automatically in this setting unless the outside
temperature is below 40
F (4
C). (Even when the
compressor is running, you can control the temperature.)
VENT: This setting brings in outside air and directs it
through the instrument panel outlets.

3-3
BI-LEV: This setting brings in outside air and
directs it two ways. Half of the air is directed through
the instrument panel outlets. Most of the remaining air is
directed through the floor ducts and a little to the defrost
and side window vents.
HTR: This setting sends most of the air through the
ducts near the floor. The rest comes out of the defroster
and side window vents.
BLEND: This setting allows half of the air to go to
the floor ducts and half to the defroster and side
window vents. The air conditioning compressor will
run automatically in this setting unless the outside
temperature is below 40
F (4
C). (Even when the
compressor is running, you can control the temperature.)
DEF: This setting directs most of the air through
the defroster and side window vents. Some of the air
goes to the floor ducts and the side window vents.
The air conditioning compressor will run automatically
in this setting unless the outside temperature is below
40
F (4
C). (Even when the compressor is running,
you can control the temperature.)
A/C: Press this button to turn the air conditioning
on and off. The system will cool and dehumidify the
air inside the vehicle when the A/C light is on.Heating
On cold days, use HTR with the driver and passenger
levers all the way in the red area. This system will bring
in outside air, heat it, and send it to the floor ducts.
Heating (Engine Coolant Heater)
If your vehicle has an engine coolant heater, you can use
it to help your system provide warm air faster when it's
cold outside
-- 0
F (-18
C) or lower. An engine
coolant heater warms the coolant your engine and
heating system use to provide heat. See ªEngine Coolant
Heaterº in the Index.
Air Conditioning
On very hot days, open the windows long enough
to let hot, inside air escape. This reduces the time for
the vehicle to cool down.
For a quick cool
-down on very hot days, use MAX
with the temperature levers all the way in the blue area.
If this setting is used for long periods of time, the air in
your vehicle may become too dry.
For normal cooling on hot days, use VENT with the
temperature levers in the blue area. The system will
bring in outside air and cool it.

3-4
On cool, but sunny days, the sun may warm your upper
body, but your lower body may not be warm enough.
You can use BI
-LEV and set the temperature levers to a
comfortable setting. The system will bring in outside air
and direct it to your upper body, while sending slightly
warmed air to your lower body. You may notice this
temperature difference more at some times than others.
Push the A/C button on for cooling.
Dual Automatic ComforTemp Climate
Control (If Equipped)
With this system, you set a temperature. You can
then either let the system automatically control airflow
direction and force to maintain the temperature, or you
can manually adjust it. The system works best if you
keep your windows closed while using it.
Automatic Control
For the most efficient operation, you should set the
system temperature and press AUTO. The system will
select the best fan speed and airflow settings to keep
you comfortable. The air conditioning compressor will
run if the outside temperature is above 40
F (4
C).
You may notice a delay of two to three minutes before
the fan comes on at start up in cool weather.
Temperature Control
The TEMP switch sets the temperature for the entire
system when the light on the DUAL button isn't lit.
If the DUAL button light is lit, this master temperature
control sets the temperature for the driver only. Press the
up arrow to raise the temperature and press the down
arrow to lower the temperature. The display will show
your selection for a few seconds, then the outside
temperature will be displayed. If you push the AUTO
button, the system will control the fan speed and airflow.
For the automatic system to function, the temperature
must be set between 61
F (16
C) and 89
F (31
C).
The driver's temperature and passenger's temperature
settings will be automatically maintained even if manual
overrides have been selected except for settings at
60
F (15
C) and 90
F (32
C).

3-6
Manual Control
If you prefer to manually control the heating, cooling and
ventilation in your vehicle, you can select airflow direction,
fan speed, outside or recirculated air, air compressor and
temperature operation with the following:
AIR FLOW: This control has several settings to control
the direction of airflow when the system is not in AUTO.
To access the various modes available, continue to press
the AIR FLOW rocker button up or down until the
desired mode appears in the display:
WINDSHIELD/FLOOR: This setting directs half of
the air to the floor ducts and half to the defroster and
side window vents. The air conditioning compressor
will run automatically in this setting unless the outside
temperature is below 40
F (4
C).
MID/FLOOR: This setting directs half of the air
through the instrument panel outlets. Most of the
remaining air is directed through the floor ducts and
a little to the defroster and side window vents.
MID: This setting directs air through the instrument
panel outlets.FLOOR: This setting sends most of the air through
the ducts near the floor. The rest comes out of the
defroster and side window vents. When in this setting
and the RECIRC setting, the windows can fog up.
See ªRECIRCº in the Index.
FRONT: This setting brings in outside air
and directs most of the air through the defrost vent.
Some of the air also goes to the floor ducts and the side
window defogger outlets. The indicator on the button
will light and WINDSHIELD will be lit in the display.
The air conditioning compressor will run automatically
in this setting unless the outside temperature is below
40
F (4
C).
VENT: This setting turns the air conditioning
compressor on and off. The indicator is lit when the
compressor is turned off. Recirculation is not permitted
when the compressor is off. The system will try to
control the temperature automatically, but without
the compressor.
VENT is not permitted in FRONT defrost mode. If the
VENT button is pushed while in FRONT defrost mode,
the indicator will light briefly and then turn off.

3-7
RECIRC: This setting recirculates much of the air
inside your vehicle. This setting is not permitted in
FRONT defrost mode and is only permitted in
WINDSHIELD/FLOOR mode if the compressor
is turned on. The indicator light will be lit when
recirculation is engaged, but will light briefly and
then turn off if selected when not permitted.
Operating the climate control system in the RECIRC
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 WINDSHIELD/FLOOR
or WINDSHIELD mode and increase the fan speed.
To avoid re
-fogging of the windows, operate the
system with RECIRC disengaged.
Defogging and Defrosting
If you have the DUAL COMFORTEMP CLIMATE
CONTROL, your system has two settings for clearing
the front and side windows. To defrost the windows
quickly, press the DEF button with the temperature
knob all the way in the red area.
For maximum defroster performance, set both driver and
passenger temperature controls to the warmest setting.
To warm passengers while keeping the windows clear,
use BLEND.
If you have the DUAL AUTOMATIC COMFORTEMP
CLIMATE CONTROL, your system has two settings
for clearing the front and side windows. To defrost the
windows quickly, press the FRONT button; set the
temperature to 90
F (32
C), select high fan speed
and turn the DUAL button off. To warm passengers
while keeping the windows clear, push the AIR FLOW
button until WINDSHIELD/FLOOR appears in the
display. Select fan speed for comfort and windshield
clearing performance.

Climate Control
The rear window defogger uses a warming grid to
remove fog from the rear window. Press the button to
turn the rear defogger on. It will turn off after about
15 minutes. If you turn it on again, the rear defogger
will only run for about 7.5 minutes before turning off.
You can also turn it off by pressing the button again.
NOTICE:
Do not attach anything like a temporary vehicle
license or decal across the defogger grid.
NOTICE:
Don't use a razor blade or anything else sharp
on the inside of the rear window. If you do, you
could cut or damage the warming grid, and the
repairs wouldn't be covered by your warranty.
