3-4 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.
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 switch 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 (Instrument Panel/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 (Instrument Panel): 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.

3-7 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.
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 for cooling.
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, turn the mode
knob to the defrost setting and turn 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.
