2002 CADILLAC ESCALADE Owners Manual

2-98
A chime will sound the first time an object is detected.
URPA can detect objects 3 inches (7.6 cm) and wider,
and at least 10 inches (25.4 cm) tall, but it cannot detect
objects that are above the center of the Cadillac crest
badge. In order for the rear sensors to recognize an
object, it must be within operating range.If the URPA system is not functioning properly, the
display will flash red, indicating that there is a problem.
The light will also flash red while driving if a trailer or
trailer hitch ball mount is attached to your vehicle or if a
bicycle or object is on the back of, or hanging out of
your vehicle. The light will continue to flash until the
trailer or the object is removed and your vehicle is
driven forward at least 15 mph (25 km/h).
It may also flash red if the ultrasonic sensors are not
kept clean. So be sure to keep your rear bumper free of
mud, dirt, snow, ice and slush or the system may not
work properly. If after cleaning the rear bumper and
driving forward at least 15 mph (25 km/h), the display
continues to flash red, see your dealer. It may also flash
red if your vehicle is moving in REVERSE (R) at a
speed greater than 3 mph (5 km/h).
Other conditions that may affect system performance
include things like the vibrations from a jackhammer
or the compression of air brakes on a very large truck.
As always, drivers should use care when backing
up a vehicle. Always look behind you, being sure to
check for other vehicles, obstructions and blind spots.
For cleaning instructions, see ªCleaning Your Vehicleº
in the Index.

Electronic Climate Control System
Fan Knob
The knob on the left side of the electronic climate control
panel is used to regulate the fan speed. To manually
increase airflow, move the knob clockwise. To manually
decrease airflow, move it counterclockwise.
OFF: If the knob is in OFF, outside air will still enter
the vehicle, and will be directed based on the position of
the mode knob.
AUTO: If the knob is in AUTO, the fan speed will vary
as the system maintains the selected temperature.
When both the fan knob and mode knob are in the AUTO
position, the system will then automatically maintain the
desired cabin temperature as selected by the temperature
knob. Manual operation is also available.Temperature Knob
The middle knob on the control panel is used to select
the desired air temperature in your vehicle. This knob
will allow you to adjust the interior air temperature
independent of the mode knob setting. Move the knob
clockwise toward 82 for warmer air. Move the knob
counterclockwise toward 66 for cooler air. When the
system is set for automatic operation, sensors will
control the fan speed.
Full Hot: If you turn the temperature knob past 82, the
system will go into the ªfull hotº mode. The system will
remain at that maximum heating setting and the fan will
blow at the speed to which the fan knob is set. If the fan
is in AUTO, it will run at full speed.
Full Cold: If you turn the temperature knob past 66, the
system will go into the ªfull coldº mode. The system
will remain at that maximum cooling setting and the fan
will blow at the speed to which the fan knob is set. If the
fan is in AUTO, it will run at full speed.

3-3
Mode Knob - Automatic Operation
The right knob on the control panel allows you to
choose the direction of air delivery. When the system is
set in AUTO mode, sensors will control the air delivery
mode. Air will come primarily from the floor or
instrument panel outlets, with some air directed to the
windshield to prevent fogging.
When the system is in AUTO mode, the air conditioning
light will turn on, and the recirculation and outside air
lights turn off. With the system in full auto control
(both the fan and mode knobs in AUTO), you still
have the ability to override any function. However,
continually overriding the outside air or the A/C
compressor will limit the ability of the system to cool
the vehicle quickly.
If you push a button for a function which is not
available, the light next to that button will flash
three times to alert you that it's not available.
To find your comfort zone, start with the 74 setting
and allow about 20 minutes for the system to adjust
the temperature if necessary.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 of the floor
outlets. As the interior temperature approaches a desired
setting, the fan speed will decrease. To maintain interior
comfort, the airflow will adjust between the instrument
panel air outlets and floor outlets. On bright sunny days
in cool weather, the airflow may come out of the air
conditioning and floor outlets (bi
-level mode) to
maintain comfort and prevent stuffiness.
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 fan speed will gradually increase and
air will flow from the floor outlets, with some airflow
to the windshield to prevent fogging under most
normal conditions.
Be careful not to put anything over the solar sensor
located near the center of the instrument panel.
This sensor is used by the automatic system to
regulate temperature.

3-4
Mode Knob - Manual Operation
The right knob on the control panel allows you to
choose the direction of air delivery.
You can choose to set the climate control system
operations yourself, or let the system work for you
by placing the system in AUTO mode. See ªMode
Knob
- Automatic Operationº earlier in this section.
(Vent): This setting directs most of the air through
the instrument panel outlets and a small amount through
the floor outlets.
(Bi-level): This setting delivers air through
the floor outlets as well as the instrument
panel outlets.
(Floor): This setting directs most of the warmed
air through the floor outlets and some air through the
windshield defroster outlets.
(Blend): This setting divides airflow equally
between the floor outlets and the windshield defroster
outlets. The air conditioning compressor may run to
dehumidify the air to prevent window fogging.
(Defrost): This setting directs most air through
the windshield defroster outlets and some through the
floor outlets. The air conditioning compressor may run
to dehumidify the air to prevent window fogging. When
using the defrost mode with auto fan speed selected, the
fan speed may be higher than normal.
(Outside air): Press this button, located under
the fan knob, to use outside air. Using outside air will
limit stale air odors and help to prevent excessively
humid interior air (from wet boots or clothing or
maximum passenger loads) from being redirected onto
windows.
Pressing the outside air button will cancel the
recirculation button and AUTO mode of the airflow.
Pressing outside air will return the system to auto mode.
(Recirculation): Press this button to limit the
amount of outside air entering the vehicle to a very
small amount. This will be helpful to limit odors
entering the vehicle and will assist in reaching comfort
in very hot temperature conditions. Pressing
recirculation will cause the system to recirculate interior
air continuously and may cause the vehicle windows
to fog if the passenger compartment floor is
excessively wet.

3-5
Pressing the recirculation button will cancel outside air
operation. To return to normal system operation and to
prevent stale passenger compartment air, be sure to
return to the outside air position.
Recirculation will not be available in floor, blend or
defrost modes. This helps reduce window fogging.
If the recirculation button is pressed in theses modes,
the LED indicator for recirculation will flash three times
indicating that forced outside air is activated and
recirculation is not available.
If the air conditioning system is activated and system
demand is high in situations such as city traffic, idling,
or very hot weather, the system will automatically
switch from outside air to recirculation. The LED
indicator will not change. After the demand on the
system is not so great, the system will return to
outside air.
(A/C): Press this button to turn the air
conditioning on and off. The system will cool and
dehumidify the air inside the vehicle when the A/C light
is on. When in AUTO, the A/C is automatically engaged
when necessary.
Air conditioning will be automatically disabled when
the outside temperature drops below a level which air
conditioning is ineffective.
Rear Air Conditioning and Rear Heater
(With Sunroof)
Your vehicle has the rear air conditioning and rear heater
system combination. Controls are provided to regulate
temperature, location and speed of the airflow.
Front Control
To adjust the airflow speed, turn the fan control knob
located on the left side to the desired setting.
To regulate the airflow direction, adjust the right knob on
the control panel. Turn the knob clockwise for floor vent
airflow or counterclockwise for headliner vent airflow.
Generally, the upper vents are used for air conditioning
and the floor vents for heating. The knob can be set to
any blend setting.
To adjust the air temperature, turn the temperature knob
on the center of the control panel.
For warmer air, turn the knob clockwise toward red. For
cooler air, turn the knob counterclockwise toward blue.

3-6 Rear Air Conditioning and Heating Systems
with Electronic Climate Control System
(Without Sunroof)
Front Control
Rear Control
With this system the rear passengers can control the air
temperature, air flow and air speed. The climate control
has three knobs.To adjust the airflow speed, turn the fan knob located on
the left side of the control panel to the desired setting.
The system can be controlled from the front controls as
well as the rear controls. Choosing AUTO from the front
will control the rear settings. Choosing OFF from the
front control will also turn off the rear climate control.
When the front control is set to REAR, the rear controls
can be used by rear seat passengers.
To adjust the air temperature on either control panel,
turn the temperature knob on the center of the control
panel. For warmer air, turn the knob clockwise
toward 82. Turn the knob counterclockwise toward 66
for cooler air.
To regulate the airflow direction, adjust the right knob
on the control panel. Turn the knob clockwise for floor
vent airflow or counterclockwise for headliner vent
airflow. Generally, the upper vents are used for air
conditioning and the floor vents for heating. The knob
can be set to any blend setting.

3-7 Air Conditioning
On hot days, open the windows long enough to let hot
air inside 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.
The A/C button, below the mode knob, allows the air
coming into your vehicle to be cooled. This setting is
useful for normal cooling on hot days. When you use
A/C with the recirculation button pressed in, turn off
recirculation as soon as the vehicle reaches a
comfortable interior temperature.
Using A/C with the recirculation setting active allows
the air inside your vehicle to be recirculated. This
setting helps to maximize your air conditioner's
performance and your vehicle's fuel economy. This
setting also cools air the fastest and can be used to keep
unwanted odors and/or dust from entering the vehicle.
When using the air conditioner, turn off the recirculation
setting and use the outside air setting after the vehicle
reaches a comfortable interior temperature. When the
right knob on the control panel is between floor and
defrost, the recirculation feature will not function to
reduce window fogging.Passenger Compartment Air Filter
Your vehicle is equipped with a passenger compartment
air filter, which filters outside air entering the vehicle.
For information on replacing the filter see ªPassenger
Compartment Air Filterº in the Index.
Heating
The heater works best if you keep your windows closed
while using it. On cold days, use the floor setting with
the temperature knob in the red area.
On cold days, approximately 32
F (
-0
C) or lower,
you may experience differences in how the transmission
shifts until the engine is warm. This feature
automatically reduces the time it takes for the engine to
reach normal operating temperature and shortens the
time it takes the heater to reach full output.
If you use the engine coolant heater before starting your
engine in cold weather, 20
F (
-8
C) or lower, the
heating system will produce warmer air faster to heat the
passenger compartment.
The use of an engine coolant heater also reduces the
time it takes for the engine to reach normal operating
temperature. For more information, see ªEngine Coolant
Heaterº in the Index.
