VENT: This setting brings in outside air and
directs it through the instrument panel outlets.
BI-LEVEL: This setting brings in outside air and
directs it two ways. Some air is directed through the
instrument panel outlets. Most of the air is directed
through the floor ducts and a little to the defrost and side
window vents.
FLOOR: This setting sends most of the air
through the ducts near the floor. The rest comes out of
the defroster and side window vents.
DEFOG: This setting allows half of the air to go
to the floor ducts and half to the defroster and side
window vents.
DEFROST: This setting directs most of the air
through the defroster and side window vents. Some of
the air goes to the floor ducts. The air conditioning
compressor will run automatically in this setting when it
is needed to help dry the air in the vehicle.
Air Conditioning Compressor Button
Press the A/C button to operate the air conditioner
compressor. The indicator light above the button will glow
when the compressor is running. You don’t have to press
the button to run the compressor in MAX or DEFROST.
Air Conditioning (If Equipped)
On very hot days, open the windows long enough to
let hot inside air escape. This reduces the time it takes
for your vehicle to cool down, which should help
fuel economy.
For quick cool
-down on very hot days, use MAX with
the temperature knob all the way in 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, use VENT with the
temperature knob in the blue area and 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
-LEVEL with the temperature knob in
the middle and the A/C button pushed in. The system
will bring in outside air and direct slightly warmer air to
your lower body. You may notice this temperature
difference more at some times than others.
