OFF:
If
the passenger comfort control is turned on,
it
can be turned off by pressing the
OFF
button once.
Pressing the
OFF
button
a
second time will turn off the
main system. Turning off the main system causes the fan
to turn off and the airflow to
be
directed to the FLOOR.
The system will still try to keep the interior of the
vehicle at the previous chosen comfort setting. The
outside temperature will show on the display when the
system is
OFF.
The ventilation system always allows fresh air to flow
through your Buick when the vehicle is moving even
with the system in the
OFF
mode.
VENT
The VENT button allows outside air to flow
through your Buick without the air conditioning
compressor working. Selecting VENT and the AUTO
button at the same time allows the system to control
automatically without the use of the air conditioning
compressor or the use of
the
RECIRC mode. To turn off
the VENT selection, push the VENT button again.
RECIRC:
When RECIRC is selected, the system
will
limit the amount of outside air entering your vehicle.
This is helpful when you are trying to cool the interior
of the vehicle quickly or limit the amount of outside
air entering your vehicle. RECIRC and AUTO may
be selected at the same time. The system
will
remain
in
RECIRC
until
the ignition is turned off, then the
system will return back to the previously selected
mode. Deselecting the RECIRC button will also turn
off the RECIRC function. RECIRC can be selected
in
all
manual airflow modes except FRONT defrost
and VENT.
FRONT
This selection is used to defrost the windshield
by directing the airflow toward the windshield.
If
FRONT is selected while in the AUTO mode, the
fan speed and the air temperature from the front
defroster
will
vary. If
a
manual fan speed setting is
selected, the fan speed will remain at that selection
until
another fan speed selection is made or the AUTO
mode is selected.
To
turn off FRONT, press the AUTO
or
AIR
FLOW
button.
FRONT defrost will work better if any ice or snow is
cleared from the hood and the air inlet area between the
base
of
the windshield and the hood.
