CADILLAC DEVILLE 1998 7.G Owners Manual

Downloaded from www.Manualslib.com manuals search engine To find your comfort zone, start with the 75 "F (24°C)
setting and allow about 30 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 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 warrns 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.

0 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.
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.

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
OW 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
ENGMET (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.
