How the System Works
URPA comes on automatically when the shift lever is
moved into REVERSE (R) and the vehicle speed is less
than 3 mph (5 km/h). When the system comes on, the
three lights on the display will illuminate to let you
know that the system is working. URPA senses how
close your vehicle is to an object. The distance is
determined by the four ultrasonic sensors located on the
rear bumper. When you shift into REVERSE (R) and an
object is detected, the following will occur in sequence
depending on the distance from the object:

At 5 feet (1.5 m) a chime will sound and one amber
light will be lit;

at 40 inches (1.0 m) both amber lights will be lit;

at 20 inches (0.5 m) a continuous chime will sound
and all three lights (amber/amber/red) will be lit; and

at 1 foot (0.3 m) a continuous chime will sound and
all three lights (amber/amber/red) will flash.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 on the tailgate. In order for the rear sensors to
recognize an object, it must be within operating range.
NOTICE:
The URPA system will not work correctly with
the tailgate lowered. You could damage your
vehicle by backing into an object before URPA
detects it. Turn off the URPA system when
driving with the tailgate lowered.

If the URPA Display Flashes Red
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 any of the
following conditions exist:

A trailer or trailer
-hitch ball mount is attached to
your vehicle.

A bicycle or object is on the back of, or hanging out
the cargo area.

If the tailgate is lowered.

If your vehicle is moving in REVERSE (R) at a
speed greater than 3 mph (5 km/h).
The light will continue to flash until the trailer or the
object is removed or the tailgate raised 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 materials such as paint 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. For
cleaning instructions, see ªCleaning Your Vehicleº in
the Index.
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.

Comfort Controls
Electronic Climate Control System
Fan Knob
The knob on the left side of the electronic climate
control panel regulates the fan speed. To manually
increase airflow, turn the knob clockwise. To manually
decrease airflow, turn 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. The temperature can also be adjusted
using the temperature knob.
AUTO (Automatic Operation): 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 selected.
Manual operation is also available.
Temperature Knob
The middle knob on the control panel lets you select
the desired air temperature in your vehicle. Turn the
knob clockwise toward 82
F (28
C) for warmer air.
Turn the knob counterclockwise toward 66
F (19
C)
for cooler air.
(Full Hot): If you turn the temperature knob past
82
F (28
C), 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
F (19
C), 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 -- 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 manually, or let the system work
automatically by turning the knob on the control
panel to AUTO. See ªMode Knob
-- Automatic
Operationº later in this section.
(Vent): This mode directs most of the air through
the instrument panel outlets and a small amount through
the floor outlets.
(Bi-level): This mode directs air through the floor
outlets as well as the instrument panel outlets.
(Floor): This mode directs most of the airflow
through the floor outlets and some air through the
windshield defroster outlets. Recirculation will not be
available in this mode. See ªRecirculationº following
for more information.
(Blend): This mode 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.
Recirculation will not be available in this mode.
See ªRecirculationº following for more information.
(Defrost): This mode 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.
Recirculation will not be available in this mode.
See ªRecirculationº following for more information.

3-4
Mode Buttons
(Outside air): Press this button 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 mode.
(Recirculation): Press this button to limit the
amount of outside air entering the vehicle to a very
small amount. This mode helps limit odors entering
the vehicle and will assist in reaching a comfortable
temperature 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.
Recirculation may be selected with the fan control in
OFF to limit odors, outside air and dust from entering
your vehicle.
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.To help reduce window fogging, recirculation will
not be available in floor, blend or defrost modes.
If the recirculation button is pressed in these modes,
the LED indicator for recirculation will flash three times
indicating that forced outside air is activated and that
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 demand on the system
is reduced, the system will return to outside air.
A/C (Air Conditioning): 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 at which
air conditioning is effective.

3-5
Mode Knobs -- Automatic Operation
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, the air conditioning light
will turn on, and the recirculation and outside air lights
will turn off. With the system in full automatic 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 air
conditioning compressor will limit the ability of the
system to cool the vehicle quickly.
If you press 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
F (23
C)
setting and allow about 20 minutes for the system to
adjust the temperature. Then set the temperature higher
or lower if necessary. The system will maintain the set
temperature.With the automatic mode, 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 outlets
and floor outlets. On bright sunny days in cool weather,
the airflow may come out of the instrument panel and the
floor outlets 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.

3-6 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 mode allows the air coming into your vehicle
to be cooled. This mode is useful for normal cooling
on hot days.
Use A/C with recirculation on to allow the air inside
your vehicle to be recirculated. This mode will help to
maximize your air conditioner's performance and your
vehicle's fuel economy. This mode also cools the air the
fastest and can be used to keep unwanted odors and/or
dust from entering the vehicle.
When using the air conditioner, in manual mode, turn
off the recirculation mode and use the outside air mode
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. This helps 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, when using manual mode,
use the floor or bi
-level mode 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.

3-7 Defogging and Defrosting
On cool, humid days, use defog to keep the windshield
and side windows clear. Use defrost to remove fog or ice
from the windshield in extremely humid or cold conditions.
Use defrost with the temperature knob toward the red area
and the fan knob turned all the way clockwise.
Rear Window Defogger
Do not remove the rear window with the rear defogger on.
You may see a discharge spark coming from the latch area
if you remove the rear window with the rear defogger on.
The lines running across the rear window are the
defogger grid. The lines warm the glass.
To turn on the rear
window defogger,
press this button located
below the mode knob.The rear window defogger will only work if the ignition
is in RUN. For best results, clear the window of as much
snow or ice as possible first.
The defogger will shut itself off after several minutes.
If you need additional warming time, press the button
again. You can turn the defogger off at any time by
pressing the button.
Your vehicle is equipped with heated outside mirrors.
The rear window defogger button will also activate the
heated outside mirrors.
Do not attach a temporary vehicle license, tape or decals
across the defogger grid on the rear window.NOTICE:
Don't use a razor blade or something else sharp
on the inside of the rear window. If you do, you
could cut or damage the warming grid, and the
repairs wouldn't be covered by your warranty.

3-8 Ventilation System
Your vehicle has air outlets
in the center and on the
sides of the instrument
panel. There are also two
outlets located on the back
of the center console for the
rear seat passengers.
You can move the louvers from side
-to-side and
up and down to direct the flow of air. The driver's and
passenger's side outlets can be closed.The two outlets, located on the rear of the center
console, can also be closed. Turn the thumbwheel to the
left to shut off air flow or to the right to allow air flow.
When you close an outlet, it will increase the flow of air
coming out of any outlets that are open. The center
outlet, located on the instrument panel, does not
completely shut off airflow.
For mild outside temperatures when little heating or
cooling is needed, use outside air to direct outside air
through your vehicle.
Your vehicle's ventilation system supplies outside air to
the inside of your vehicle when it is moving. With the
side windows closed, air will flow into the front air inlet
grilles, through the vehicle, and out the air exhaust valves.
Outside air will also enter the vehicle when the heater or
the air conditioning fan is running, unless you have the
recirculation mode active. For more information on the
recirculation button, see ªAir Conditioningº earlier in
this section.
