(Floor): This setting sends most of the air through
the floor ducts. The remaining air comes out of the
defroster and side window outlets. The recirculation
button cannot be selected in this mode.
(Defogger): 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.
(Defroster): 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.Mode Buttons
(Outside Air): Press this button to force the
system to use outside air. This button is usable in 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 can be used in the vent and bi
-level
modes. An indictor 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 defogger or
defroster mode and increase the fan speed. To avoid
refogging of the windows, use the outside air setting.
A/C (Air Conditioning): 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 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 select a fan
setting, turn the mode knob on the control panel to vent;
press the A/C and the recirculation buttons and move the
temperature controls 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 vent; press the A/C and the
outside air buttons and move the temperature control all
the way into the blue area. The system will bring in
outside air and cool and dehumidify 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 select a fan setting, turn the
mode knob on the control panel to the bi
-level mode,
press the A/C button, and move the temperature control
to a comfortable setting.
Heating
On cold days, select a fan setting, turn the mode knob on
the control panel to floor, press 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, select a fan setting and turn the mode
knob on the control panel to vent. Press the outside
air button and move the temperature controls 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
defroster with the temperature controls all the way in the
red area. To warm passengers while keeping the
windows clear, use defogger. For more information,
see ªRecirculationº in the Index.

Audio Systems
Your audio system has been designed to operate easily
and give years of listening pleasure. You will get the
most enjoyment out of it if you acquaint yourself with it
first. Find out what your audio system can do and how
to operate all of its controls to be sure you're getting the
most out of the advanced engineering that went into it.
