:
(Outside Air): Press this button to turn the
outside air mode on. When the button is
pressed, an indicator light will come on. When this
mode is on, outside air will circulate throughout
the vehicle. The outside air mode can be used with
all modes, but it cannot be used with the
recirculation mode.
?
(Recirculation): Press this button to turn
the recirculation mode on. When the button
is pressed, an indicator light will come on.
This mode keeps outside air from entering the
vehicle. It can be used to reduce outside air and
prevent odors from entering the vehicle.
Recirculation may also help cool the air inside the
vehicle more quickly once the temperature
inside the vehicle is less than the outside
temperature.
The recirculation mode cannot be used with floor,
defog or defrost modes. If recirculation is
selected with one of these modes, the indicator
light will flash three times and then turn off. While
in recirculation mode the windows may fog
when the weather is cold and damp. To clear the
fog, select either the defog or defrost mode
and increase the fan speed.
The recirculation mode can be turned off by
pressing the outside air button, or by turning off
the ignition.
#
(Air Conditioning): Press this button to turn
the air conditioning system on or off. When this
button is pressed, an indicator light on the button
will come on to let you know the air conditioning is
activated. The air conditioning can be selected in
any mode as long as the fan switch is on.
The air conditioning system removes moisture
from the air, so you may sometimes notice a small
amount of water dripping underneath your
vehicle while idling or after turning off the engine.
This is normal.
Defogging and Defrosting
Fog or frost on the inside of windows is a result of
high humidity (moisture) condensing on the cool
window glass. This can be minimized if the climate
control system is used properly. To avoid fogging
windows on rainy and humid days at temperatures
above freezing, run the air conditioning
compressor. It is best to avoid the use of the
recirculation mode, except when maximum A/C
performance is needed or for short times to avoid
exterior odors.
