OFF - 12: This message means that the air conditioning
system detects
a refrigerant level that is low enough to
cause damage to the air conditioning compressor.
To avoid damage, the air conditioning compressor
automatically turns off and the Electronic Climate
Control will automatically switch from AUTO to AC
and remain there. Have the air conditioning system
serviced if this message appears.
Continuous Variable - Real Time Damping
(CV-RTD) (DeVille Concours Only)
The CV-RTD automatically adjusts the ride of your
vehicle. Automatic ride control is achieved through
a
computer controller used to control and monitor the
suspension system. The computer controller receives
inputs from various sensors to determine the proper
system response. If the computer controller detects a
problem within the system, the DIC will display a
SERVICE RIDE CONTROL message. If this
message appears, have your vehicle serviced at your Cadillac dealership.
Oil Life Indicator
This feature lets you know when to change the engine
oil. It's based on the engine oil temperatures and
your driving patterns.
To see the display, press the
INFORMATION (INFO) button until
XX OIL LIFE
LEFT appears.
If you see 99% OIL LIFE LEFT,
99 percent of your current oil life remains.

Downloaded from www.Manualslib.com manuals search engine The DIC may display a CHECK OIL LEVEL message.
Always keep a written record of the mileage and date
when you changed your oil. For more information, see
the Cadillac Maintenance Schedule booklet. If you see
CHECK
OIL LEVEL, it means that you have less than
10 percent of the oil life left and you should consider
changing your engine oil. If you see CHANGE
ENGINE OIL, it means the oil life is gone and you
should change the oil right away.
The system should indicate changing the oil between
3,000 miles (5 000 km) and 7,500 miles (12 500 km).
It may indicate changing the oil before 3,000 miles
(5 000 km) depending on your driving habits. If the vehicle has been driven
7,500 miles (12 500 km), it will
indicate to change the oil.
If you drive in a dusty area,
you should change your oil every
3,000 miles (5 000
km) or three months (whichever comes first) unless the
display indicates changing it sooner. The system doesn’t
check
how much oil you have, so you’ll still have to
check for that.
To see how, see “Engine Oil” in
the Index.
When new oil
is added, you’ll need to reset the system.
To reset, display the Oil Life Indicator by pressing the
INFORMATION (INFO) button. Then press and hold
the RESET button until the display shows 100% OIL
LIFE LEFT.

This section tells you how to make your air system work
for
you. Your Electronic Climate Control (ECC) system
uses ozone-friendly
R- 134a refrigerant.
With the ECC system, you can control the heating,
cooling and ventilation in your Cadillac. Your vehicle
also has
a flow-through ventilation system described
later in this section.

Fan Button
The button with the fan symbol adjusts the fan speed. Press the up arrow
to increase fan speed and the down
arrow
to decrease fan speed.

Downloaded from www.Manualslib.com manuals search engine Driver’s Side Temperature Button
The red and blue temperature buttons adjust the air
temperature coming through the system. Press the blue
button for a cooler setting or the red button for a
warmer setting.
Passenger’s Side Temperature Knob
With this feature, the right front passenger can control
the temperature of 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 knob on the passenger’s
side armrest. Rotate the knob clockwise to increase the
temperature and turn counterclockwise to decrease the
temperature. Press the knob again
to turn the system off.
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 ENG/MET (Englishlmetric)
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.
Mode Controls
The AUTOBCON button automatically controls the
direction of air delivery for air conditioning and non-air
conditioning modes.
Automatic Operation
When the system is set for automatic operation, 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.

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.
