Push the PASS button on the system face
so the light
on
it is lit. Turn the knob on the door toward red

The indicator light on the button will glow when the
button is pressed.
RECIRC: This setting recirculates much of the air
inside your vehicle and sends it through the instrument
panel outlets. The air conditioning compressor will run
automatically
in this setting unless the outside
temperature
is below 40°F (4.5"C).
UPPER: This setting brings in outside air and directs it
through the instrument panel outlets.
BI-LEV. This setting brings in the outside air and
directs it two-ways. Half of the air is directed through
the instrument panel outlets.
Most of the remaining air is
directed through the floor ducts and a little to the defrost
and side window vents.
LOWER: This setting sends most of the air through the
ducts' near the floor. The rest comes out of the defrost
and side window vents.
DEFOG: This setting allows half of the air to go to the
floor ducts and half to the defrost and side window
vents.
DEF: This setting directs most of the air through the
defrost and side window vents. Some of the air goes
to
the floor ducts. The air conditioning compressor will run
automatically in this setting unless the outside

Automatic Control
For the most efficient operation, you ,should.set the
system temperature and press the knob. The system will
select the best fan speed and air flow, settings to keep
you comfortable. The air conditioning compressor will
run
if the outside temperature is above 40°F (4.5 ” C).
YOU may notice
a delay of three to four minutes before
the fan comes on.
Manual Control
If you prefer to manually control the heating, cooling
and ventilation
in your vehicle, push UPPER, BI-LEV,
LOWER, DEFOG or
DEE AUTO will go off the
display. Set the system to the temperature and fan
speed you want. The system will try to maintain the
temperature you set using the mode you select. The
following suggestions will help the system run more
efficiently in manual mode.
Air Conditioning
On very hot days, open the windows long enough to
let hot inside
air escape. This reduces the time the
compressor has to run, which should help fuel economy.
For quick cool-down on very hot days, use RECIRC. 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, use UPPER with the
A/C button pushed
in. 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. You
can use BI-LEV with the A/C’ button pushed in.’
The system will bring in outside air and direct it to your
upper body, while sending slightly warmed air to your
lower body. You may notice this temperature difference
more at some times than.others.
Heating
On cold days use LOWER. The system will bring in
outside air, heat it and send it to the floor ducts.
If your vehicle has an engine coolant heater, you, can use
it to help your system provide warm air faster when it’s
cold outside
(0°F (-18°C) or lower). An engine coolant
heater warms the‘coolant your engine and heating
system use to provide heat. See “Engine Coolant
Heater” in the Index.
Ventilation
For mild outside temperatures when little heating or
cooling is needed, use-UPPER to direct outside air through
your vehicle.
Your vehicle also has the flow-through
ventilation system described later in
this section.

Flow-Through Ventilation System
Your vehicle's flow-through ventilation system supplies
outside air info the vehicle when it is moving. Outside
air will also enter the vehicle when the air conditioning
fan
is running.
Ventilation Tips
Keep the hood and fkont 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, set the
mode to
FLQOR or LOWER and the fan to .the
highest speed 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.
'0 Keep the air path under the front seats'clear of
objects. This helps air to circulate throughout your
vehicle.
