Buick 2005 Century - Manual (Page 119)

VENT (Ventilation): This mode brings in outside air
and directs it through the instrument panel outlets.
BI-LEV (Bi-Level): This mode directs approximately
half of the air to the instrument panel outlets, and then
directs most of the remaining air to the floor outlets.
Some air may be directed toward the windshield.
HTR (Heater): This mode directs most of the air to the
floor outlets, with some air directed to the outboard
outlets, for the side windows, and some air directed to
the windshield.
BLEND: This mode directs half of the air to go to the
floor outlets and half to the defroster and side window
outlets. The air-conditioning compressor will run
automatically in this setting unless the outside
temperature is below 40°F (4°C).
The right knob can also be used for the defrost mode.
Information on defrosting and defogging can be
found later in this section.

FAN: The left knob controls the fan speed.
OFF: Turn the knob all the way counterclockwise to
turn off the fan.
LO (Low Fan Speed): This setting creates the lowest
fan speed.
HI (High Fan Speed): This setting creates the highest
fan speed.
DRIVER (Driver’s Side Temperature): The lever on
the left adjusts the air temperature for the driver’s
side outlets. Slide the lever up to raise the temperature
and down to lower the temperature.
PASSENGER (Passenger’s Side Temperature):
The lever on the right adjusts the air temperature for the
passenger’s side outlets. Slide the lever up to raise
the temperature and down to lower the temperature.
A/C (Air Conditioning): Press this button to turn
the air-conditioning on and off. An indicator light above
the button will come on when the air conditioning is
on. During daylight hours the interior lighting control
might need adjustment to the highest setting in order
for the indicator light to be seen. The system will
cool and dehumidify the air inside the vehicle when the
A/C indicator light is on.
On very hot days, open the windows long enough to let
hot, inside air escape. This reduces the time for the
vehicle to cool down.
