Safety Belt Warning Light and Chime
This warning light and chime remind you to fasten your safety
belt.
mIf the safety belt is not buckled when the ignition is turned to
the ON position, the chime will sound for four (4) to eight (8)
seconds and the light will remain on until the safety belt is
fastened.
mIf the safety belt is buckled while the light is on and the chime
is sounding, both the light and chime will turn off.
mIf the safety belt is buckled before the ignition is turned to the
ON position, the chime does not sound, and the warning light
will not illuminate.
Air Bag Readiness Light
The supplemental air bag system uses a readiness light to
indicate the condition of the system. If the system is functioning
properly, the light will illuminate for about six (6) seconds
when the ignition switch is turned to the ON position.
If there is a problem with the system, the readiness light may fail
to illuminate, continue to flash, or remain on. If any of these
conditions occur, have the system serviced as soon as possible.
Unless the system is serviced, the supplemental air bag system may
not function properly in the event of a collision.

WARNING
Operating with the function selector control in off or in
the recirculated air mode for extended periods of time in
cold weather can result in fog buildup on interior glass
surfaces.
mThe Mix () button directs approximately equal amounts
of air to the windshield and floor outlets with a small
amount to the side windows.
mThe Defrost (
) button directs air to the windshield and
front side windows with a small amount going to the floor
outlets.
mThe Panel (
) button directs air to the instrument panel
outlets.
mThe Panel/Floor (
) button directs approximately equal
amounts of air to the instrument panel outlets and the floor
outlets.
mThe Floor (
) button directs most of the system's air
supply to the floor outlets with a small amount going to the
windshield and side window defrosters.
Air Outlets
Air intake selector button
The typical air intake selection is outside air. However, for
recirculated air, the air intake selector button may be activated.
When the air intake selector button is activated (indicator light is
on), it prevents the intake of outside air. This is the typical
selection when using the air conditioner (if equipped). It
recirculates interior air for faster cooling. The recirculated air
function also helps to prevent the intake of dusty or unpleasant air.
Controls and Features
57

There are several air outlets on the instrument panel. There are
side outlets near the driver's window and passenger's window, two
center outlets, floor outlets, and windshield outlets. The
direction and amount of air flow from the center and side
instrument panel outlets can be adjusted for personal comfort.
NOTE: Selection of the recirculated air mode under cold and
humid conditions may result in window fogging due to
entrapped humidity within the vehicle. To counteract
this circumstance, switch to the Defrost mode and set fan
speed to 3 or 4. Adjust air temperature to a ªwarmº
instead of ªhotº setting and deactivate the air intake
selector.
Heating Only System (Without air conditioning)
You can heat and ventilate the inside of your vehicle, or defrost
the windshield with the function selector buttons, the fan speed
knob and the temperature control knob.
An additional push-on/push-off air intake selector button
provides for the selection of recirculated inside air (button lighted)
or outside air (button not lighted).
58

To defrost the windshield and side windows:
mPress the Defrost button, turn the temperature control knob to
the WARM (red) area and turn the fan speed knob to the
position of your choice. The recirculated air feature will be
automatically turned off in this setting (outside air will be
provided).
mTo reduce window fogging under extreme conditions, select
defrost and high fan speed while reducing temperature to a
ªwarmº instead of ªhotº setting. Deactivating the air intake
selector may also help dry the interior window surfaces.
To heat and defrost at the same time:
mPress the Mix function selector button, turn the temperature
control knob and the fan speed knob to provide the
temperature and fan speed you prefer. The recirculated air
feature will be automatically turned off in this setting (outside
air will be provided).
Controlling the Temperature in Your Vehicle
mTo ventilate your vehicle with outside air, make sure that the
air intake selector button is set for outside air. Open the
instrument panel registers enough to provide the amount of
air desired for your comfort.
mTo vary the temperature inside your vehicle, move the
temperature control knob toward WARM (red) for warmer
temperatures and toward COOL (blue) for cooler temperatures.
The temperature control knob setting determines the
temperature of the air being discharged from the system in all
operating modes (heating or A/C).
60

mDo not place objects under the front seats unless your vehicle
is equipped with an underseat storage compartment.
Improperly stored objects will interfere with the flow of air to
the back seats.
mRemove any snow, ice, or leaves from the area below the
windshield on the outside of your vehicle. They could block the
air intake.
Heating and Air Conditioning System (If equipped)
Turning on the heat
You can heat the inside of your vehicle and defrost the
windshield using the function selector buttons located in the
control assembly in the instrument panel.
The six function selector buttons are: OFF, Mix (
), Defrost
(
), Panel (), Panel/Floor (), and Floor (). If your
vehicle is equipped with a rear seat climate control system, the
instrument panel will also include a rear seat climate control lever.
To turn on the rear passenger compartment control system,
select REAR, 1, 2, 3, or 4. With the lever set to REAR, rear seat
passengers will have control of rear fan speed on the rear seat
climate control panel. Positions 1, 2, 3, or 4 will control rear
fan speed from the front control panel. The temperature of the air
from the rear system is controlled by the rear passenger
compartment climate control system.
Controls and Features
61

The standard heating system and the heating portion of the heating
and air conditioning system are essentially identical. There is
one exception, however; the air conditioning compressor may
automatically engage when the Defrost position is selected to aid in
defogging and defrosting the inside glass. When Defrost is
selected, the A/C compressor will automatically operate when
the outside temperature is above approximately 40É F (4É C),
whether or not the A/C button is illuminated. Manual
selection and illumination of the A/C button in defrost mode
does not override the automatic compressor operation discussed
above. Refer to the heating system operating instructions
covered previously for a more detailed explanation of heating
system operation.

Turning on the air conditioner
To cool your vehicle quickly in warm weather:
1. Press one of the function selector buttons (typically Panel, but
Panel/Floor, Floor or Mix can be selected).
2. Turn the temperature control knob to COOL.
3. Press the A/C button. The indicator light on the A/C button
will illuminate.
4. The air intake selector button may be in the outside air mode
or the recirculated air mode. The outside air mode is
recommended for best A/C performance when the vehicle
interior is very warm. As interior air comfort is reached, you
may decide to switch to the recirculated air mode.
5. Turn the fan speed knob to the position of your choice.
6. If your vehicle is equipped with the rear passenger compartment
air conditioning unit, it will be on when the front A/C is on
and the rear climate control lever is set to REAR, 1, 2, 3, or 4.
Refer to the previous section for an explanation of the
heating system.
7. Adjust your instrument panel registers.
8. If the inside of your vehicle is very warm, you may want to
drive for a few minutes with the windows down and the air
conditioner on. This forces most of the hot, stale air out of the
vehicle and allows the air conditioner to cool down the
interior more quickly.
The air conditioner may be used to cool the outside air being
drawn into your vehicle, but using recirculated air is more
economical and cools your vehicle more quickly.
Controls and Features
63

NOTE: The A/C button independently toggles the A/C system's
compressor signal and indicator light ON and OFF in
the Panel, Panel/Floor, Floor, Defrost and Mix functions.
The A/C button will not operate or light when the
system is set in the OFF position. The A/C button will
operate in defrost but will not override previously
discussed automatic operation.
Cooling your vehicle with outside air
Cooling your vehicle with air conditioned outside air is quieter
but less economical than using recirculated air. It also has less
cooling capacity.
To cool your vehicle using outside air:
1. Turn the air intake selector button off (the outside air
position). The air conditioning unit directs outside air through
the instrument panel registers.
2. Press one of the function selector buttons.
3. Press the A/C button. The indicator light on the A/C button
will illuminate.
4. Turn the temperature control knob to COOL.
5. Turn the fan speed knob to the position of your choice.
6. Make sure the registers in the instrument panel are open.
During periods of high humidity, vapor may be emitted from the
air outlets when using the A/C with outside air. Correct this
by switching to recirculated air with the A/C button.
