Downloaded from www.Manualslib.com manuals search engine Temperature Knob
The TEMP knob adjusts the air temperature coming
through the system. Turn the
TEMP knob clockwise to
increase the temperature and counterclockwise to
decrease
the temperature. The outside temperature is
always displayed when your vehicle is running.
Automatic Operation
Mode Button
Press this button to deliver air through the floor, middle
or windshield outlets. The system will stay in the
selected mode until
the MODE button is pushed again.
Press the
up or down arrow to cycle through the
available modes.
When the system is set for AUTO, sensors will control
the air delivery mode. Air will come
from the floor,
middle or windshield outlets. The fan speed will vary as
the system maintains the selected temperature setting.
Be careful not to put anything over the solar sensor
located in the middle
of the instrument panel near the
windshield. This sensor
is used by the automatic system
to regulate temperature.
To find your comfort zone, start with 75°F (24°C)
setting, 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 this 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 A/C 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 in the air outlets. As the air is cooled, the
airflow will move through the A/C outlets. If you start
your vehicle
with the fan setting on HI it will skip the
A/C 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 AUTO 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 middle instrument
panel outlets while warmed air
is directed to the floor,
’’ HEATER/DEFROS’E This setting directs air to
the floor outlets and toward the windshield.
’/J 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.
@? DE-ICE (Option): Pressing this button helps to
remove ice or frost from the windshield. See “Heated
Windshield’’ later in this section.
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. This feature is not
available with the heated windshield option.
% FAN SPEEDS: Press the button with the fan
symbol 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 HIGH 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
HIGH AUTO is shown on the display. If you want the
blower fan at a low speed, press the down arrow button
until
LOW is shown on the display. If you want the fan
speed
to run lower than the AUTO setting, press the
button until LOW 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 OW.

Downloaded from www.Manualslib.com manuals search engine 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.
DUAL TEMPERATURE CONTROL: With this
feature, the right front passenger can control the
temperature of heated air for hisher 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. 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.
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
ECC system, press the AUTO/ECON 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 dual-zone system, press the AC button
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. Turn the TEMP knob clockwise to increase
the temperature and counterclockwise
to decrease
temperature. Adjust 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.

With
the ECC system, press the AUTOECON button to
direct airflow out
of the floor outlets 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 dual-zone system, press the MODE
button to select heater. This will direct airflow out of the
floor outlets. Adjust the interior temperature to your
comfort level by turning the
TEMP knob clockwise to
increase temperature and counterclockwise to decrease
temperature. 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 outlets. The heater works best if you
keep your windows closed while using it. 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 aifflow by moving the center control levers
or
you can stop the airflow by moving the lever located
on each side
of the outlets downward.

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.
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.
The direction
of airflow for the rear seats can also be
adjusted. Move the
FAN lever to adjust the blower speed
from
LO to HI. Move the VENT lever to direct airflow
toward the upper or floor outlets.

Downloaded from www.Manualslib.com manuals search engine Heated Windshield (Option)
The heated windshield will remove ice or frost in cold
weather.
1. Remove snow that is piled up on the windshield.
2. Start your Cadillac and leave it in PARK (P).
3. Press the DE-ICE button. A light will come on to tell
you
it is working. Try not to use other electrical
equipment while the system is working.
The system will go off after a four-minute heating cycle.
If you shift out of PARK (P), the system will only cycle
for two minutes.
If you want it to cycle again, press the
button.
It will go on for two-minute cycles after that. If
the windshield has cleared before the cycle is over, you
can turn
it off by pressing the button again. Use
the defroster feature to clear
fog from the
windshield
as previously described.
There is
a metal film in the windshield which will block
out some radio or microwave signals. Therefore, the
heated windshield will reduce the
useful range of
devices such as garage door openers and radar detectors.
(In certain states, radar detectors are legal.)
Do not use the DE-ICE button if your vehicle has a.
cracked windshield.
A crack will not allow the system to
function properly. Have the windshield repaired before
using the DE-ICE button again.
