The TEMP/AUTO knob adjusts the air temperature coming
through the system.
Turn the TEMP/AUTO knob clockwise
to increase the temperature and counterclockwise to
decrease the temperature. Press the
TEMWAUTO knob to
put the system
in the automatic mode.
Passenger’s Side Temperature Button
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 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 OFF 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 (Englishlmetric) 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 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.
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 OF (24°C)
setting and allow about
20 minutes for the system to
regulate. Turn the
TEMP/AUTO knob to adjust the
temperature
if necessary. If you choose 60°F (1 6"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 O 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 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.

# 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.

Downloaded from www.Manualslib.com manuals search engine 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.
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.

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 ducts 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.

Downloaded from www.Manualslib.com manuals search engine Defogging and Defrosting
On cool, humid days, use DEFOG (digital cluster
climate control panel only) to keep the windshield and
side windows clear. Use DEFROST to remove fog or
ice from the windshield quickly in extremely humid or
cold conditions.
With the digital cluster climate control panel, press the
DEFOG button and adjust the fan speed by pressing the
fan button up or down.
If you use DEFROST, adjust the
fan speed the same way. If you select DEFROST from
AUTO, the system will control the fan speed. The
temperature will also need to be adjusted to your
comfort level. Press the blue button to decrease the
temperature and the red button to increase the
temperature.
If you have the analog cluster climate control panel,
press the DEFROST 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.
Note that recirculation is not available in the defrost or
defog modes.
Rear Window Defogger
