3-4
Mode Buttons
(Outside air): Press this button to use outside air.
Using outside air will limit stale air odors and help to
prevent excessively humid interior air (from wet boots
or clothing or maximum passenger loads) from being
redirected onto windows.
Pressing the outside air button will cancel the
recirculation mode.
(Recirculation): Press this button to limit the
amount of outside air entering the vehicle to a very
small amount. This mode helps limit odors entering
the vehicle and will assist in reaching a comfortable
temperature in very hot temperature conditions.
Pressing recirculation will cause the system to
recirculate interior air continuously and may cause
the vehicle windows to fog if the passenger
compartment floor is excessively wet.
Recirculation may be selected with the fan control in
OFF to limit odors, outside air and dust from entering
your vehicle.
Pressing the recirculation button will cancel outside
air operation. To return to normal system operation
and to prevent stale passenger compartment air, be sure
to return to the outside air position.
To help reduce window fogging, recirculation will
not be available in floor, blend or defrost modes.
If the recirculation button is pressed in these modes,
the LED indicator for recirculation will flash three times
indicating that forced outside air is activated and that
recirculation is not available.
If the air conditioning system is activated and system
demand is high in situations such as city traffic, idling,
or very hot weather, the system will automatically
switch from outside air to recirculation. The LED
indicator will not change. After demand on the system
is reduced, the system will return to outside air.
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
is on. When in AUTO, the A/C is automatically engaged
when necessary.
Air conditioning will be automatically disabled when
the outside temperature drops below a level at which
air conditioning is effective.
