GM Owner Manuals - Buick

W (Floor/Defog): This mode clears the windows of fog
or moisture. Air is directed to the floor outlets, with
some air directed to the windshield and side window
outlets. The system turns off recirculation and runs the
air-conditioning compressor unless the outside
temperature is at or below freezing. The recirculation
mode cannot be selected while in the floor/defog mode.
0 (Defrost): This mode removes fog or frost from
the windshield more quickly. Air is directed to the
windshield and the side window outlets. The system
automatically turns off recirculation and runs the
air-conditioning compressor, unless the outside
temperature is at or below freezing. Recirculation cannot
be selected while in the defrost mode.
# (Air Conditioning): Press to turn the air conditioning
system on or off and override the automatic system.
An indicator light below the button comes on to
show that this mode is on.
The air conditioning system removes moisture from the
air, so a small amount of water might drip under the
vehicle while idling or after turning off the engine. This is
normal.
: (Outside Air): Press to let outside air enter the
vehicle. An indicator light comes on to show this mode
is on. Pressing ? cancels this mode.
? (Recirculation): Press to turn the recirculation
mode on. An indicator light below the button comes on
to show that this mode is on. This mode recirculates
and helps to quickly cool the air inside the vehicle. It can
be used to prevent outside air and odors from entering
the vehicle. This mode cannot be selected while in
the defog or defrost modes. If you try to select
the recirculation mode, the indicator light flashes three
times and turns off.
Operation in this mode during periods of high humidity
and cool outside temperatures may result in increased
window fogging. If window fogging is experienced, select
the defrost mode.
PASS (Passenger Climate Control): Press to turn the
passenger climate control systems on or off.
When the passenger climate control system is on, the
passenger temperature setting is displayed.
If the PASS button is pressed to turn the passenger
temperature setting off, the driver temperature setting
controls the temperature for the entire vehicle.
