boot CHEVROLET AVALANCHE 2002 1.G Owners Manual

3-3
(Floor): This setting directs most of the
warmed air through the floor outlets and center floor
console outlets (if equipped), as well as some air
through the windshield defroster outlets and side
window defroster outlets. If air from the center floor
console outlets is not desired, turn the vents off at the
console. Recirculation will not be available in this mode.
See ªRecirculationº following for more information.
(Blend): Airflow is delivered through the floor
outlets, center floor console outlets (if equipped), the
windshield defroster outlets and the side window defroster
outlets. The air flow can be divided between floor and
defrost depending upon where the knob is placed between
the settings. The air conditioning compressor may run
to dehumidify the air to prevent window fogging.
Recirculation will not be available in this mode. See
ªRecirculationº following for more information.
(Defrost): This setting directs most of the air
through the windshield defroster outlets with airflow
also delivered from the side window and the floor
outlets. When in defrost mode, the air conditioning
compressor may run to assist in dehumidifying the
air and limit window fogging. Recirculation will not be
available in this mode. See ªRecirculationº following
for more information.
(Outside Air): This setting should be used for
normal system operation and directs the system to use
outside air. This button is located under the fan knob.
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 button.
(Recirculation): This setting limits the amount
of outside air entering the vehicle to a very small
amount. This button is located under the fan knob. This
will be helpful to limit odors entering the vehicle and
will assist in reaching comfort in very high
temperatures. 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.
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.

3-6
(Blend): This setting divides airflow equally
between the floor outlet and the windshield defroster
outlets. The air conditioning compressor may run
to dehumidify the air to prevent window fogging.
Recirculation will not be available in this mode. See
ªRecirculationº following for more information.
(Defrost): This setting directs most air through
the windshield defroster outlets and some through the
floor outlets. The air conditioning compressor may
run to dehumidify the air to prevent window fogging.
Recirculation will not be available in this mode. See
ªRecirculationº following for more information.
(Outside Air): Press this button, located under
the fan knob, 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 button.
(Recirculation): Press this button to limit the
amount of outside air entering the vehicle to a very small
amount. This will be helpful to limit odors entering the
vehicle and will assist in reaching comfort 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.
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.
Recirculation will not be available in floor, blend or
defrost modes to help reduce window fogging. If the
recirculation button is pressed in theses modes, the
LED indicator for recirculation will flash three times
indicating that forced outside air is activated and
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 not so great, the system will return back to outside air.
