Manual Operation
RECIRCULATION: Press this button to limit the
amount of fresh air entering your vehicle. This is helpful
when you are trying to cool the air quickly or limit odors
entering your vehicle. In the AUTO mode, the system
will use recirculation as necessary to cool the air.
Pressing the recirculation button will change the
operation to a manual mode and the air will recirculate
non
-stop. Press this button again to turn off the
recirculation feature.
If you notice the windows fogging, press the
recirculation button to exit the recirculation mode.
OFF: Press this button to turn the system off. Fresh air
will continue to flow through the vehicle, and the
system will try to maintain the previously set
temperature. The outside temperature will show in the
display when the system is off.
DEFOG: Press this button to divide the air between the
windshield and the heater outlets. This is useful when
fog appears on the windshield or side glass due to
sudden rain or snowy conditions.
AUTO/ECON: Press this button to switch between
AUTO and ECON. The ECON setting attempts to keep air
at a selected temperature, however, it does not remove
humidity from the air. Use this setting in cold or coolweather to save fuel. The AUTO setting is used when
it's warm outside and you need to cool the air in order to
maintain a selected temperature and blower speed.
FAN SPEEDS: Press the button with the fan symbol
on it until AUTO is displayed on the screen. At this
setting, the fan speed is automatically controlled. If it is
cold outside, the blower may not run in the maximum high
fan speed right away. The system checks the temperature
of the engine coolant to assure it is warm enough to
provide heat. When the engine coolant is warm, the
controller allows the fan to gradually increase to a higher
speed. This prevents cold air from blowing into the
passenger compartment. If you want the blower fan at a
high speed, press the up arrow button until you see HI on
the display. If you want the fan speed to be automatic, but
you like the fan speed to be higher than the AUTO setting,
press the fan symbol button until HI AUTO is shown on
the display. If you want the blower fan at a low speed,
press the down arrow button until LO is shown on the
display. If you want the fan speed to run lower than the
AUTO setting, press the button until AUTO LO is shown
on the display.
DEFROST: Press this button to quickly remove
fog or frost from the windshield. This setting sends most
of the airflow to the windshield with only a small
amount to the floor outlets.

3-6 Analog Cluster Climate Control Panel
(DeVille Concours Only)
Fan Button
The button with the fan symbol adjusts the fan speed.
Press the up arrow to increase fan speed and the down
arrow to decrease fan speed.
Driver's Side Temperature Knob
The TEMP/AUTO knob adjusts the air temperature
coming through the system. Turn the TEMP/AUTO
knob clockwise to increase the temperature and
counterclockwise to decrease the temperature. Press
the TEMP/AUTO knob to put the system in the
automatic mode.Passenger's Side Temperature Button
With this feature, the right front passenger can control
the temperature of air for his/her own zone. The
passenger can select a four degree warmer or cooler
temperature from the driver's setting.
To turn the system on, press the PASS/TEMP button
located below the radio. Press the up arrow to increase
the temperature and press the down arrow to decrease
the climate setting. Pressing the OFF button will turn
off the dual
-zone function.
Outside Temperature Display
The outside temperature is always displayed when your
vehicle is running. You can change it from Fahrenheit to
Celsius by pressing the ENG/MET (English/metric)
button on the Driver Information Center (DIC).
The outside temperature sensor is located near the front
grille. The sensor can be affected by road or engine heat
during idling, slow driving or when the engine is first
started after a short trip. In order to ensure proper
automatic climate control operation, the outside air
temperature display may not update as quickly as
expected. This is to allow the air surrounding the outside
temperature sensor to be as close to the actual outside
conditions as possible. This is determined by how much
time has elapsed since the vehicle has been turned off
and by vehicle speed.

If you leave your vehicle, the system will remember
the control setting the next time you start your engine,
except for recirculation and defrost. Each ignition cycle
cancels recirculation, whereas, DEFROST will change
to automatic operation when the ignition is shut off and
then turned back on.
Manual Operation
You may manually adjust the air delivery mode or
fan speed.
AC: This setting directs airflow through the middle
instrument panel outlets.
BI-LEVEL: This setting directs air into your
vehicle in two ways. Cool air is directed to the upper
portion of your body through the four instrument panel
outlets while warmed air is directed to the floor.
HEATER/DEFROST: This setting directs air to
the floor outlets and toward the windshield.
HEATER: This setting directs warmed air
through the floor outlets. Some warm air is diverted to
the windshield to minimize fogging.
DEFROST: Press this button to quickly remove
fog or frost from the windshield. This setting sends most
of the airflow to the windshield with only a small
amount to the floor outlets.
FAN SPEEDS: Press the button with the fan
symbol on it until AUTO is displayed on the screen.
At this setting, the fan speed is automatically controlled.
If it is cold outside, the blower may not run in the
maximum high fan speed right away. The system
checks the temperature of the engine coolant to assure
it is warm enough to provide heat. When the engine
coolant is warm, the controller allows the fan to
gradually increase to a higher speed. This prevents
cold air from blowing into the passenger compartment.
If you want the blower fan at a high speed, press the up
arrow button until you see HI on the display. If you want
the fan speed to be automatic, but you like the fan speed
to be higher than the AUTO setting, press the fan
symbol button until HI AUTO is shown on the display.
