(Fan): The center knob on the control panel is used
to control the fan speed. Turn the knob clockwise or
counterclockwise to increase or decrease the fan speed.
If the knob is set on "0" (zero), some outside air will
still enter the vehicle and will be directed according to
the position of the mode knob.
Mode Knob
The right knob on the control panel is used to direct the
airflow inside the vehicle. Turn the knob to select one
of the following modes:
H
(Vent): Select this mode to direct air to the
instrument panel outlets.
\
(Bi-Level): Select this mode to direct approximately
half of the air to the instrument panel outlets, and the
remaining air to the floor outlets and the defroster
and side window outlets. Cooler air is directed to the
upper outlets and warmer air to the floor outlets.
[
(Floor): Select this mode to direct air to the floor
outlets. Recirculation is disabled in this mode because
interior window could fog under some conditions. If
this occurs, see "Defogging and Defrosting" following.
Mode Buttons
@
(Recirculation): Press this button to turn the
recirculation mode on or off. An indicator light on the
button comes on to show that the recirculation mode is
activated. This mode recirculates air inside the cabin,
and prevents outside air from coming in the vehicle.
It can be used to cool the air inside the vehicle
more quickly.
Recirculation is only available and should only be used in
the bi-level and vent modes. Recirculation is not available
while in heat, floor, floor/defog, or defrost modes. If your
try to select recirculation while in one of those modes,
the indicator light will not come on or flash.
#
(Air Conditioning): Press this button to turn the air
conditioning system on or off. An indicator light on the
button comes on to show that the air conditioning is
activated. When the system is on, this setting cools
and dehumidifies the air entering the vehicle.
The air conditioning will not function if the fan is
turned off.
You may notice a slight change in engine performance
when the air conditioning compressor shuts off and
turns on again. This is normal. The system is designed
to make adjustments to help with fuel economy while
still maintaining the selected temperature.
