Comfort Controls
This section tells you how to make your air system
work for you.
With these systems, you can control the heating, cooling
and ventilation in your vehicle.
Heater Controls
If your vehicle does not have air conditioning, your
heater controls will look like this.
Fan Knob
The knob on the left side of the heating system control
panel regulates the fan speed. The knob has four speed
positions. To increase airflow, turn the knob toward HI.To decrease airflow, turn it toward LO. To turn the fan
off, turn the mode knob on the far right to OFF.
Temperature Knob
The middle knob on the control panel regulates the
temperature of the air flowing into your vehicle. Turn
the knob toward the red area for warmer air. Turn the
knob toward the blue area for cooler air.
Mode Knob
The right knob changes the heater setting.
VENT: This setting directs air through the
instrument panel vents.
BI-LEVEL: This setting divides airflow between
the heater floor vents and instrument panel vents.
HEAT: This setting directs air through the heater
floor vents.
HEAT/DEFOG: This setting divides airflow
between the heater floor vents and windshield.
DEFROST: This setting directs air through the
windshield defroster vents. This setting is used to
remove fog or ice from the windshield.

3-3 Heater/Air Conditioning Controls
(If Equipped)
If your vehicle has air conditioning, your heater/air
conditioning controls will look like this.
Before using your vehicle's air conditioning, open the
windows to clear the vehicle of hot air.Fan Knob
The knob on the left side of the heating system control
panel regulates the fan speed. The knob has four speed
positions. To increase airflow, turn the knob toward HI.
To decrease airflow, turn it toward LO. To turn the fan
off, turn the mode knob on the far right to OFF.
Temperature Knob
The middle knob on the control panel lets you select the
temperature of the air flowing into the passenger
compartment of your vehicle. This knob will allow you to
adjust the air temperature independently of the function knob
setting. Turn the knob toward the red area for warmer air.
Turn the knob toward the blue area for cooler air.
Mode Knob
The right knob on the control panel changes the
heater/air conditioning setting.
MAX A/C: Turn the right knob to MAX A/C for
maximum cooling. This setting puts the system in the
recirculation mode and helps to maximize your air
conditioner's performance and your vehicle's fuel
economy. This setting also cools the air the fastest. After
the vehicle's interior reaches a comfortable temperature,
turn the knob clockwise to place the air conditioning
system in the A/C mode.

3-4
A/C: This setting is used for normal cooling on hot
days. It cools outside air and directs it through the
instrument panel outlets.
BI-LEVEL A/C: This setting divides airflow
between the heater floor vents and instrument panel
vents. The air conditioning compressor will cycle
continuously in this setting as long as the outside air
temperature is warm enough to activate the compressor.
VENT: This setting directs air through the
instrument panel vents.
HEAT: This setting directs air through the heater
floor vents. It is useful for cold weather.
HEAT/DEFOG: This setting divides airflow
between the heater floor vents and the windshield. In the
blended position, the air conditioning compressor is
automatically activated to dehumidify the air.
DEFROST: This setting directs air through the
windshield defroster vents. It is useful when you have
fog or ice on the windshield.
Rear Heater (Without Air Conditioning)
(If Equipped)
If you have a rear heater (without rear air conditioning),
the control is located on the instrument panel.
To increase and decrease the flow of heated air to the
rear floor vents, turn the thumbwheel marked REAR
HEAT to the speed you want.
The thumbwheel has three speed positions. To increase
the flow of heated air, turn the thumbwheel toward
HIGH. To turn the fan off, turn the control to OFF.

3-5 Rear Air Conditioning and Rear Heater
(If Equipped)
If your vehicle has a rear air conditioning and rear
heater system combination, controls are provided
to regulate the temperature, location and speed of
the airflow.
Front Passenger ControlTo adjust the air temperature, turn the temperature knob
on the right side of the control panel.
For warmer air, turn the knob toward the red area, and
for cooler air, turn the knob toward the blue area.
To regulate the airflow location, adjust the center knob
on the control panel. Turn the knob counterclockwise
for floor vent airflow or clockwise for headliner vent air
flow. Generally, the upper vents are used for air
conditioning and the floor vents for heating. The control
knob can be set to any blend setting.
To adjust the airflow speed, turn the fan knob on the left
side of the control panel to the desired fan speed.
To activate the rear control, turn the fan knob on the
front control to REAR CNTL.

3-6
Rear Passenger Control
The rear control works just like the front control. It will
allow second seat passengers to adjust the controls if the
front control is switched to the rear position.
Air Conditioning
Before using your vehicle's air conditioning, open the
windows to clear the vehicle of hot air. This reduces the
time it takes for your vehicle to cool down. Then keep
your windows closed for the air conditioner to work at
its best.
You can use MAX A/C with the temperature knob in the
blue area when it's really hot outside and you need to
cool the inside air quickly. MAX A/C lets in only a little
air from the outside.
If you first use MAX A/C, you can then use A/C with
the temperature knob in the blue area, as soon as the
vehicle has cooled down, so outside air will be going
through your vehicle.
If your vehicle has rear air conditioning, setting it on
LO may enhance front A/C performance by allowing
trapped refrigerant in rear lines to circulate.
When the air conditioning is on, you may notice a slight
increase or decrease in engine speed, due to compressor
operation. This is normal because the system is
designed to cycle the compressor on and off to keep
the desired temperature.

3-7
Heating
On cold days, use HEAT with the temperature knob in
the red area. Outside air will be brought in through the
floor outlets. The heater works best if you keep your
windows closed while using it.
If you use the optional engine coolant heater before
starting your engine, your heating system will produce
warmer air faster to heat the passenger compartment in
cold weather. See ªEngine Coolant Heaterº in the Index.
Defrosting
Use DEFROST to remove fog or ice from the
windshield quickly in extremely cold conditions. The
temperature knob should be in the red area and the fan
knob toward high. The air conditioning compressor may
operate in this setting to dehumidify the air.
Rear Window Defogger (If Equipped)
If you see lines running across the rear windows, you
have a rear window defogger. The lines warm the glass.
For best results, clear the windows of as much snow or
ice as possible before using the rear window defogger.
To turn on the rear window
defogger, press this button
located near the fan control.
An indicator light in the
button will come on when
the rear window defogger
is working.
The rear window defogger will only work when the
ignition is in RUN.
The rear window defogger will turn itself off after
several minutes. If you need additional warming time,
press the button again. Pressing the button when the
indicator light is illuminated will turn the defogger off.
If your vehicle is equipped with heated outside rearview
mirrors, the rear window defogger button will activate
both the rear window defogger and the heated outside
rearview mirrors. See ªHeated Outside Rearview
Mirrorsº in the Index.

3-8
Do not attach a temporary vehicle license, tape or decals
across the defogger grid on the rear windows. Use care
not to damage the wiring bands that connect the rear
window defogger grid when operating the rear
swing
-out windows (if equipped).
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.
Ventilation System
For mild outside temperatures when little heating or
cooling is needed, use VENT to direct outside air
through your vehicle. Air will flow through the
instrument panel vents.
Your vehicle's flow
-through ventilation system supplies
outside air to the inside of your vehicle when it is
moving. With the side windows closed, air will flow into
the front air inlet grilles at the base of the windshield,
through the vehicle and out the rear air exhaust valve.
Outside air will also enter the vehicle when the heater or
the air conditioning fan is running.
Your vehicle has air vents near the center and on the
sides of the instrument panel that allow you to adjust the
direction and the amount of airflow inside the vehicle.
Move the dial on the vent up or down to direct airflow
to your preference. Increase or reduce the amount of
airflow by opening and closing the louvers. The vents
turn to direct the airflow from side to side.
