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.

3-4
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).

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.
