Black plate (18,1)Buick Lucerne Owner Manual - 2011
-(Floor/Defog):This clears the windows of fog or
moisture. Air is directed to the windshield and side
window outlets and to the floor outlets. The system runs
the air conditioning compressor unless the outside
temperature is near or below freezing.
0(Defrost): This mode clears the windshield of fog
or frost more quickly. Air is directed to the windshield
and side window outlets. The system runs the air
conditioning compressor unless the outside temperature
is near or below freezing.
#(Air Conditioning): Press to turn the air
conditioning system on or off. An indicator light
below the button comes on to show that this mode
is on. Air conditioning can be selected in any mode
as long as the fan knob is not in the off position.
On hot days during the vehicle's initial start-up, open
the windows to let hot inside air escape; then close
them. This helps to reduce the time it takes for the
vehicle to cool down. It also helps the system to operate
more efficiently. For quicker cool down on hot days, do the following:
1. Select
H.
2. Select
h.
3. Select
#.
4. Select the coolest temperature.
5. Select the highest fan speed.
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.
h(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.

Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog from the rear window.
<(Rear Window Defogger):Press to turn the rear
window defogger on or off. An indicator light below the
button comes on to show that the rear window defogger
is on. Be sure to clear as much snow from the rear
window as possible.
The rear window defogger only works when the
ignition is in ON/RUN. The rear window defogger stays
on for about 20 minutes after the button is pressed if
traveling at slow speeds. At higher vehicle speeds, the
rear defogger may stay on continuously. If turned on
again, the defogger only runs for about 10 minutes
before turning off. The defogger can be turned off by
pressing the button again, by turning the ignition to
ACC/ACCESSORY or ON/RUN, or by turning off the
engine. If the vehicle has heated outside rearview mirrors, the
mirrors heat to help clear fog or frost from the surface
of the mirror when the rear window defogger is on.
See
Outside Heated Mirrors
on page 3‑34for more
information.
Notice: Do not use anything sharp on the inside of
the rear window. If you do, you could cut or damage
the warming grid, and the repairs would not be
covered by the vehicle warranty. Do not attach a
temporary vehicle license, tape, a decal, or anything
similar to the defogger grid.

AUTO (Automatic Mode)
1. Turn the fan control to AUTO.
2. Turn the mode control to AUTO.
3. Adjust the temperature to a comfortable settingbetween 68°F (21°C) and 78°F (26°C).
Choosing the coldest or warmest temperature
setting will not cause the system to heat or cool
any faster. In cold weather, the system starts at
reduced fan speeds to avoid blowing cold air
into the vehicle until warmer air is available. The
system will start out blowing air to the floor, but
may change modes automatically as the vehicle
warms up to maintain the chosen temperature
setting. The length of time needed to warm the
interior depends on the outside temperature.
4. Wait a few minutes for the system to automatically regulate. Then adjust the temperature as
necessary to find your comfort setting.
Do not cover the solar sensor located in the center of
the instrument panel, near the windshield. For more
information on the solar sensor, see “Sensors”later in
this section.
After the vehicle is started, the display shows the
interior temperature settings. When the ENG/MET (English/metric) button on the
Driver Information Center (DIC) is pressed, the display
shows readings in Fahrenheit or Celsius. Use the
ENG/MET button to toggle between the readings.
AUTO (Automatic Air Conditioning):
If AUTO is
selected on the fan or mode control, the system
automatically controls the air conditioning compressor.
The A/C compressor runs automatically even at cool
outside temperatures in order to dehumidify the air. The
A/C indicator light is lit when the system is operating
automatically. Press the A/C button on the fan control to
turn off the A/C. To clear windows better in defog or
defrost modes, the A/C compressor runs automatically
in damp cool conditions.
h(Auto Recirculation): If AUTO is selected on
either the fan or mode control, the system automatically
controls the supply of fresh outside air or recirculates
the interior air to cool the car faster. The indicator light
on the recirculation button will light whenever the
system switches to recirculation. You may force outside
air by pressing the outside air button. The next time
AUTO fan or mode is selected, it will reset back to
AUTO operation.

There is also an interior temperature sensor located
next to the steering wheel that measures the
temperature of the air inside the vehicle.
There is also an exterior temperature sensor located
behind the front grille. This sensor reads the outside air
temperature and helps maintain the temperature inside
the vehicle. Any cover on the front of the vehicle could
cause a false temperature reading to display.
In order to prevent false temperature readings at
startup, the displayed temperature will not change
until the following occurs:
.Vehicle speed is above 10 mph (16 km/h) for
five minutes.
.Vehicle speed is above 32 mph (51 km/h) for
two and a half minutes.
The climate control system uses the information from
these sensors to maintain your comfort setting by
adjusting the outlet temperature, fan speed, and the
air delivery mode. The system may also supply cooler
air to the side of the vehicle facing the sun. The
recirculation mode will also be used as needed to
maintain cool outlet temperatures.
