1997 CADILLAC DEVILLE ECO mode

Downloaded from www.Manualslib.com manuals search engine To find your comfort zone, start with the 75°F (24°C)
setting and allow about 20 minutes for the system to
regulate. Press the red or blue temperature buttons
to
adjust the temperature if necessary. If you choose 60°F
(16"C), the system will remain at that maximum cooling
setting and will not regulate fan speed. If you choose the
temperature of
90°F (32"C), the system will remain at
that maximum heating setting and will not regulate fan
speed. Choosing either maximum setting will not cause
the system to heat or cool any faster.
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 aifflow 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 cornfort 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,
DEFROST will change
to automatic operation when the ignition
is shut off and
then turned back on.

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.
AUTOECON: 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 cool weather 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.
9 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.

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.
With the digital cluster climate control panel, press the
AUTOECON button to assist in cooling air and in
maintaining proper airflow. Adjust the temperature to a
comfortable setting by pressing the blue button to cool
your vehicle and pressing the red button to
warm your
vehicle. Press the fan button arrows up
or down to adjust
the fan speed.
If you have the analog cluster climate control panel,
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.

Downloaded from www.Manualslib.com manuals search engine Heating
With the digital cluster climate control panel, press the AUTOECON button to direct airflow and to help save
fuel. Adjust the temperature, if necessary, by pressing
the blue button to decrease temperature and pressing the
red button to increase temperature. Also remember to
adjust the fan speed by pressing the up or down
arrow.
If you have the analog cluster climate control panel,
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.
With each system, 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.
Ventilation System
Your Cadillac’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.
