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
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 Knob
The center knob sets the temperature for the driver's
outlets. Turn the knob toward red (clockwise) for
warmer air. Turn it toward blue (counterclockwise) for
cooler air.
Passenger's Temperature Lever
The bottom lever adjusts the air temperature on the
passenger's side independent of the temperature set by
the driver. Slide the lever toward the right to raise the
temperature. Slide the lever toward the left 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.)

Heating
On cold days, use HTR with the temperature knob and
lever all the way in the red area. The system will bring
in outside air, heat it and send it to the floor ducts.
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.
Ventilation
For mild outside temperatures when little heating or
cooling is needed, use VENT to direct outside air through
your vehicle. Your vehicle also has the flow
-through
ventilation system described later in this section.
Defogging and Defrosting
Your system has two settings for clearing the front and side
windows. To defrost the windows quickly, use FRONT 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.
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.
