2000 CADILLAC ELDORADO Owners Manual

3-4
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, 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.
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.

3-5
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 LO AUTO is
shown on the display.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 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 display will show
that AC is active, but the air conditioning compressor
only operates when the system determines it is needed.
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 AC button or the TEMP/AUTO knob to turn
the system on and then select the proper mode to direct
airflow. 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 Defrosting
Use defrost to remove fog or ice from the windshield
quickly in extremely humid or cold conditions.
Press the MODE button. If you 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/AUTO 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.
If further defogging is desired, press 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 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.
The direction of airflow for the rear seats can also be
adjusted. Move the fan lever to adjust the blower speed
from low to high. Move the vent lever to direct
the airflow.
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.

3-9

When you enter a vehicle in cold weather, adjust the
fan to the highest speed for a few moments before
driving off. This helps clear the intake outlets of
snow and moisture, and reduces 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.
HVAC Steering Wheel Controls
Some heating and cooling
controls can be adjusted at
the steering wheel. Other
touch controls operate some
audio controls. SeeªAudio
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)
This feature allows both driver's (driver 1 or 2 depending
on the number on the back of your remote keyless entry
transmitter) to personalize their own climate control
settings. For more information, see ªMemory and
Personalization Featuresº in the Index.
