CADILLAC DEVILLE 2000 8.G Owners Manual

3-4
With the automatic setting, the air conditioning
compressor automatically cycles when needed to cool
the air. In cold weather, when the system senses the need
for heat, the airflow will be directed out the floor
outlets. As the interior temperature approaches a desired
setting, the blower speed will decrease. To maintain
interior comfort, the airflow may move to the instrument
panel air outlets and floor outlets (bi
-level mode). On
bright sunny days in cold weather, the airflow may come
out of the air conditioning outlets (AC mode) to
maintain comfort and prevent stuffiness.
If your vehicle is sitting out on a hot day and you have it
set on AUTO, the air will first flow out the floor air
outlets for a few seconds. That is normal. This is to
expel hot air from the air outlets. As the air is cooled,
the airflow will move through the air conditioning
outlets. If you start your vehicle with the fan setting on
HI, it will skip the air conditioning purge.
To avoid blowing cold air in cold weather, the system
will delay turning on the fan until warm air is available.
The length of delay depends on the outside air
temperature, engine coolant temperature or the time
since the engine was last started. As the coolant warms
up, the blower fan speed will gradually increase and air
will flow from the heater outlets, with some airflow to
the windshield to prevent fogging under most normal
conditions.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, FRONT DEFROST will
change to auUse only household glass cleaner and a soft
cloth. Wipe gently and dry throughly.tomatic 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 four
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.

3-5
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 AUTO. 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.
OFF: Press the knob 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 on
the display when the system is OFF.AC: Press this button to turn the air conditioning on and
off. The system will cool and dehumidify the air inside
the vehicle. In the AUTO mode the air conditioning
compressor only operates when the system determines it
is needed. The display will show A/C OFF when the air
conditioning is off.
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.

3-6 Electronic Solar Sensor
The sensor monitors the sun's solar radiation and is
located on top of the instrument panel near the
windshield. The ECC panel uses this information to
automatically make the necessary temperature and
airflow adjustments to maintain your comfort.
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.
Press the AUTO button or the TEMP knob to turn the
system on. The system will cool and dehumidify the air
inside the vehicle. Also while in the AUTO mode, the
system will use recirculation as necessary to cool the air.
You may also need to adjust the interior temperature and
the fan speed as needed.
When the air conditioner is on, you may sometimes
notice slight changes in your vehicle's engine speed
and power. This is normal because the system is
designed to cycle the compressor on and off to keep the
desired temperature.
Heating
Press the MODE button to select heater. Adjust the
interior temperature to a comfortable level and if the fan
speed needs adjusting, press the up or down arrow.
Outside air will be brought in and sent through the floor,
air conditioning or bi
-level outlets (depending on the
condition). The heater works best if you keep your
windows closed while using it.

3-7 Defogging and Defrosting
On cool, humid days, use defog HEATER/DEFROST to
keep the windshield and side windows clear. Use defrost
to remove fog or ice from the windshield quickly in
extremely humid or cold conditions.
Press the MODE button to select DEFROST. Adjust the
fan speed by pressing the fan button up or down. If you
select DEFROST from AUTO, the system will control
the fan speed. The temperature also needs to be adjusted
by turning the TEMP knob.
RECIRCULATION is not available in the defrost or
defog modes.
Rear Window Defogger
The lines you see on the
rear window warm the
glass. Press this button to
turn on the rear defogger.
With it, the rear window
and both outside rearview
mirrors are heated.The system will automatically shut off after 10 minutes
of use. If you turn it on again, the defogger will operate
for about five minutes. However, if your vehicle is
traveling above 30 mph (48 kph) the system will not
shut off. You can also turn the defogger off by turning
off the ignition or by pressing the button again.
Do not attach a temporary vehicle license, tape or decals
across the defogger grid on the rear window.
NOTICE:
Don't use a razor blade or something else sharp
on the inside of the rear window. If you do, you
could cut or damage the warming grid or the
integrated rear window antenna, and the repairs
wouldn't be covered by your warranty.

3-8 Rear Climate Control
Your vehicle is equipped with a rear climate control.
With this system, the rear passengers can control thetemperature of the air flow for his/her own zones. The
climate control has three buttons:
Mode: Press this button to adjust the direction of the
airflow. Press again to use the AUTO adjust mode and
let the system decide for you.
Fan: Press the button with the fan symbol on it to adjust
the blower speed.
Temp: Press this button to adjust the temperature.
The system also has a front AUTO button that can
automatically change the temperature of the rear seating
area, based on information from the front system. A
PASS
-OFF button located on the front climate control
panel also allows the driver to turn off the rear passenger
seat controls from the front seat.

3-9 Ventilation System
Your vehicle's flow-through ventilation system supplies
outside air into the vehicle when it is moving. Outside
air will also enter the vehicle when the heater or the air
conditioning fan is running.
The front outlets are located in the center and at each
side of the instrument panel. You can adjust the
direction of airflow by moving the center control levers
or you can stop the airflow by moving the lever located
on each side of the outlets downward.Ventilation Tips

Keep the hood and front air inlet free of ice, snow or
any other obstruction (such as leaves). The heater
and defroster will work far better, reducing the
chance of fogging the inside of the windows.

Keep the air path under the front seats clear of
objects. This helps circulate air throughout
your vehicle.
Passenger Compartment Air Filter
This ventilation system includes an air filter that helps to
remove dust, pollen, etc. from the air flowing into your
vehicle. A restriction in the airflow coming into the
passenger compartment could be the result of dirt in
the filter. For more information, see ªPassenger
Compartment Air Filter Replacementº in the Index.
Also see the Maintenance Schedule booklet for when to
change the filter.

3-10 HVAC Steering Wheel Controls
Some heating and cooling
controls can be adjusted at
the steering wheel. Other
touch controls operate some
audio controls. See ªAudio
Steering Wheel Controlsº
in the Index.
FAN SPEED: Press the up arrow lever to increase
the fan speed and the down arrow lever to decrease
fan speed.
TEMP: Press the up arrow lever to increase the
temperature and the down arrow lever to
decrease temperature.
Climate Control Personalization
(If Equipped)
With this feature, your vehicle will recall the latest
climate control settings as adjusted the last time your
vehicle was operated. This feature allows two different
drivers to store and recall their own climate control
settings. The settings recalled by the climate control
system are determined by which remote keyless entry
transmitter (ª1º or ª2º) was used to enter the vehicle.
The number on the back of the remote keyless entry
transmitter corresponds to driver 1 or to driver 2. After
the unlock button is pressed on the remote keyless entry
transmitter or the ignition key is placed in the ignition
(the ignition must be turned to OFF), the climate control
settings will automatically adjust to where they were last
set. The settings can also be changed by briefly pressing
the memory seat buttons 1 or 2 located on the
driver's door.
