Comfort Controls
Manual Single Zone Climate Control
With this system, you can control the heating, cooling
and ventilation in your vehicle. The system works best if
you keep your windows closed while using it.
Fan Knob
The knob on the left side of the climate control panel
regulates the fan speed. To turn the fan off, turn the
knob to OFF.If airflow seems very low when the fan knob is turned to
the highest setting, regardless of the mode setting, your
passenger compartment air filter (if equipped) may need
to be replaced. See ªMaintenance Scheduleº in the Index.
Temperature Knob
The center knob on the control panel changes the
temperature of the air coming through the system.
Turn this knob toward red (clockwise) for warmer air.
Turn it toward blue (counterclockwise) for cooler air.
Mode Knob
The right knob on the control panel has several settings
to control the direction of the airflow:UPPER: This setting directs air through the
instrument panel outlets.
BI-LEVEL: This setting directs air two ways.
Half of the air is directed through the instrument panel
outlets. Most of the remaining air is directed through the
floor vents and a small amount to the windshield
defroster and side window outlets.

3-3
LOWER: This setting sends most of the air
through the ducts near the floor. The remaining air
comes out of the defroster and side window outlets.
The RECIRCULATION button cannot be selected
in this mode.
DEFOG: This setting sends half of the air
to the floor ducts and half to the defroster and side
window outlets. The air conditioning compressor will
run automatically in this setting unless the outside
temperature is below 40
F (4
C). The air inlet
will also be automatically set to outside air. The
RECIRCULATION button cannot be selected in
this mode.
DEFROST: This setting directs most of the air
through the defroster and side window vents. Some of
the air also goes to the floor ducts. The air conditioning
compressor will run automatically in this setting unless
the outside temperature is below 40
F (4
C). The
air inlet will also be automatically set to outside air.
The RECIRCULATION button cannot be selected
in this mode.
OUTSIDE AIR: Press this button to force the
system to use outside air. This button is usable with all
of the mode settings. An indicator on the button will
light up when this button is selected.
RECIRCULATION: Press this button to limit
the amount of outside air entering your vehicle. This is
helpful when you are trying to limit odors entering your
vehicle. This button is usable in UPPER and BI
-LEVEL
modes. An indicator on the button will light up when
this button is selected. The system will default back to
the outside air setting, so you will have to reselect this
setting every time you restart your vehicle.
While in the RECIRCULATION mode the system
may cause fogging of the windows when the weather
is cold and damp. To clear the fog, select either the
DEFOG or DEFROST mode and increase the fan
speed. To avoid refogging of the windows, use the
OUTSIDE AIR setting.
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 and the fan are on.

3-4 Dual ComforTemp

inside the vehicle when the A/C light and the fan are on.

3-6 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. Then keep your windows closed
for the air conditioner to work its best.
For quick cool down on very hot days, turn the mode
knob on the control panel to UPPER; push the A/C
button on; push the RECIRCULATION button on and
move the temperature control(s) all the way into 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, turn the mode knob on
the control panel to UPPER; push the A/C button on;
push the OUTSIDE AIR button on and move the
temperature control all the way into 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.
To remedy this you can turn the mode knob on the
control panel to BI
-LEV. Push the A/C button on and
move the temperature control to a comfortable setting.
Heating
On cold days, turn the mode knob on the control panel
to LOWER, push the OUTSIDE AIR button on and
move the temperature control all the way in the red area.
The system will bring in outside air, heat it and send it to
the floor ducts.
Ventilation
For mild outside temperatures when little heating or
cooling is needed, turn the mode knob on the control
panel to UPPER; push the A/C button off; push the
OUTSIDE AIR button on and move the temperature
control(s) to a comfortable setting. 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
DEFROST with the temperature control(s) all the way
in the red area. To warm passengers while keeping the
windows clear, use DEFOG. For more information,
see ªRecirculationº in the Index.

3-7 Rear Window Defogger
Press the button marked
REAR to turn the defogger
on. An indicator on the
button will light.
When turned on, the rear window defogger uses a
warming grid to remove fog from the rear window.
If your vehicle has the optional heated outside mirrors,
they will heat to clear the mirror surface before driving.The rear window defogger and the mirrors will
automatically turn off after about 15 minutes. If you
turn them on again, the defogger and the mirrors will
only stay on for about seven and one half minutes before
turning off again. You can also turn them off by turning
the ignition off or by pressing the button again.
Do not attach anything like a temporary vehicle license
or decal across the defogger grid.
NOTICE:
Don't use a razor blade or something 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.
Don't put decals there because you might have
to scrape them off.

3-8 Ventilation System
Adjust the direction
of airflow by moving
the vents.
Your vehicle's flow
-through ventilation system supplies
outside air into the vehicle when it is moving. Outside
air will also enter the vehicle when the air conditioning
fan is running and the OUTSIDE AIR button is pushed.
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 (if equipped) may
need to be replaced. See ªMaintenance Scheduleº in
the Index.Ventilation Tips

Keep the hood and front air inlet free of ice, snow or
any other obstruction (such as leaves). The heater
and defroster will work far better, reducing the
chance of fogging the inside of your windows.

When you enter a vehicle in cold weather, adjust the
mode knob to LOWER and the fan to the highest
speed for a few seconds before driving off. This
helps clear the intake ducts of snow and moisture
and reduces the chance of fogging the inside of
your windows.

Keep the air path under the front seats clear of
objects. This helps air to circulate throughout
your vehicle.
