To find your comfort setting, start with the system in
AUTO mode and the
TEMP button adjusted to a display
of
75 OF (24"C), give the vehicle about 20 minutes to
stabilize, and adjust your comfort setting if necessary, by
using the TEMP button. The display will show the
comfort setting, fan speed and airflow direction for a few
seconds, and then it will display the outside temperature.
In cold weather, the system will delay turning the fan on
high, to avoid blowing cold air. The length of the delay
depends on the engine coolant temperature and the
outside temperature. Pushing the FAN, AIR FLOW
or FRONT buttons will override this delay, turn
off the
AUTO setting and change the fan speed.
Manual Operation
You may also manually adjust the air delivery or fan speed.
AIR FLOW This button is used to change the direction
of the aifflow. The airflow choices available are FLOOR,
FLOOR-MID,
MID and WINDSHIELD-FLOOR. If the
system is set
for AUTO, pressing the AIR FLOW button
will display the current airflow direction, the comfort
setting and the fan speed. Press the AIR FLOW up or
down button again
to change the direction of the airflow.
If the AIR FLOW up button is selected while in the
FRONT defrost mode, the system will direct the air
toward the mid-position.
If the AIR FLOW down button is
selected while
in the FRONT defrost mode, the system
will direct the air toward the
FLOOR, and the FRONT
defrost mode will cancel. Notice the arrows in the display.
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 for some other reason. RECIRC
and AUTO may be selected at the same time. The
system will remain in RECIRC until the ignition is
turned
off. The system will return back to the previously
selected mode when the car is turned back on. RECIRC
can be selected in all manual airflow modes except
FRONT defrost. RECIRC cannot be selected with the
VENT button.
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.
Air Conditioning
On hot days, open the windows long enough to let hot
inside air escape. This reduces the time it takes for your
vehicle
to cool down. Then keep your windows closed
for the air conditioner to work its best.
On very hot days, the system will automatically enter
the RECIRC mode and the temperature door will be
positioned at the full cold position for maximum
cooling. If the system is not in the AUTO mode,
RECIRC should be selected to provide maximum
cooling.
You can choose the extreme comfort setting of
60°F (16"C), but the system will not cool any faster
by choosing the extreme comfort setting.
Heating
Press AUTO and adjust the temperature by pressing the
TEMP up or down arrow. You may also adjust the dual
automatic comfortemp system manually by pressing the
AIR FLOW button until FLOOR appears. Again, adjust
the temperature by pressing the TEMP up or down arrow.
Outside air will be brought in and sent through the
floor outlets. The heater works best if you keep your
windows closed.
