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 controls 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 controls 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: Use this setting to divide airflow
between the heater floor vents and instrument
panel vents.
HEAT: This setting directs air through the heater
floor vents. This setting is useful for cold weather.

yellowblue
3-3
HEAT/DEFROST: Use this setting to divide
airflow between the heater floor vents and windshield.
DEFROST: This setting directs air through the
windshield defroster vents. This setting is useful when
you have fog or ice on the windshield.
Heater/Air Conditioning Controls
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 controls 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 area 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: Use for normal cooling on hot days. This setting
cools outside air and directs it through the instrument
panel outlets.
BI-LEVEL A/C: Use this setting to divide airflow
between the heater floor vents and instrument panel
vents. The air conditioning compressor may operate in
this setting to cool the air.
VENT: This setting directs air through the
instrument panel vents.
HEAT: This setting directs air through the heater
floor vents. This setting is useful for cold weather.
HEAT/DEFROST: Use this setting to divide
airflow between the heater floor vents and windshield.
DEFROST: This setting directs air through the
windshield defroster vents. This setting is useful when
you have fog or ice on the windshield.
Rear Heater (Without Air Conditioning)
If you have a rear heater (without rear air conditioning),
the control switch 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 blower speed you want.
The knob has three speed positions. To increase the flow
of heated air, turn the thumbwheel toward HIGH. To
turn the fan off, turn the switch to OFF.

3-5 Rear Air Conditioning and Rear Heater
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 control knob
on the left side of the control panel to the desired
blower setting.
To activate the rear control, turn the fan knob on the
front control to REAR CNTL.

Rear Passenger Control
The rear control works just like the front control. It will
allow second seat passengers to adjust the controls as
they desire.
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, DEFROST or BLEND 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.

Heating
On cold days, use HEATER 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.
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
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.

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 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, turn the
blower fan to HI for a few moments 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.
Your vehicle has air vents in the center and on the sides
of your instrument panel.
You can move the vents from side to side or up and
down to direct the flow of air, or close the vents
altogether. When you close a vent, it will increase the
flow of air coming out of any vents that are open.
