2002 BUICK PARK AVENUE display

2-100
A chime will sound the first time an object is detected,
if the object is between 20 inches (0.5 m) and 5 feet
(1.5 m) away.
URPA can detect objects 3 inches (7.6 cm) and wider,
and at least 10 inches (2.5 cm) tall, but cannot detect
objects that are above trunk level. 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 when you are driving if a
trailer is attached to your vehicle, or if you have a
bicycle or an object hanging out of your trunk. 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. For cleaning instructions, see
ªCleaning Your Vehicleº in the Index.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 then
driving 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 airbrakes
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
This section tells you how to operate your
comfort controls.
With this system, you can control the heating, cooling
and ventilation in your vehicle. Your vehicle also has a
flow
-through ventilation system described later in
this section.
Dual Automatic ComforTemp

Climate Control
Your vehicle has the dual automatic ComforTemp
climate control system. The following information tells
you how it works.TEMP (Temperature): To adjust the temperature, press
the TEMP arrows. If you want a warmer temperature,
press the red arrow. If you want a cooler temperature,
press the blue arrow. The temperature setting is shown
in the display.
FAN: If you want the fan to run at a lower speed,
press the down arrow on the FAN button. The fan speed
will decrease with every press of the down arrow until
the lowest speed is reached. If you want to increase the
fan speed, press the up arrow on the FAN button. The
fan indicators will also be shown on the display.
Pressing this button will display the current setting.
AIRFLOW: Press the up or down arrow to change the
direction of the airflow. The available choices are FLOOR,
FLOOR
-MID, MID and WINDSHIELD-FLOOR.
If the system is set for AUTO, pressing an up or down
arrow will display the current airflow direction, the
temperature setting and the fan speed.
If the up arrow is selected while in the FRONT defrost
mode, the system will direct the air toward the
mid
-position. If the down arrow is selected while in the
FRONT defrost mode, the system will direct the air
toward the floor, and the FRONT defrost mode will
cancel. The arrows will also be shown in the display.

3-3
Mode Buttons
VENT: The VENT button allows outside air to flow
through your vehicle without the air conditioning
compressor working. Selecting the VENT and AUTO
buttons at the same time allows the system to control the
air flow automatically without using the air conditioning
compressor or the recirculation mode. To turn off the
VENT selection, press the VENT button again.
RECIRC (Recirculation): When RECIRC is selected,
the system will limit the amount of outside air entering
your vehicle. This is helpful when you are trying to cool
the interior of the vehicle quickly or limit the amount of
outside air entering your vehicle for some other reason.
RECIRC and AUTO may be selected at the same time.
The system will remain in recirculation until the ignition
is turned off. The system will return to the previously
selected mode when the car is restarted. RECIRC can be
selected in all manual airflow modes except FRONT
defrost and VENT.
FRONT: This selection is used to defrost
the windshield by directing the airflow toward
the windshield.If FRONT is selected while in the AUTO mode, the fan
speed and the air temperature coming from the front
defroster will vary. If a manual fan speed is selected, it
will remain until another fan speed or the AUTO mode
are selected. To turn off FRONT, press the AUTO or
AIR FLOW button.
FRONT defrost will work better if ice or snow is cleared
from the hood and the air inlet area, located between the
base of the windshield and the hood.
OFF: If the passenger comfort control is turned on,
it can be turned off by pressing the OFF button once.
Pressing the OFF button a second time will turn off the
main system. Turning off the main system causes the fan
to turn off and the airflow to be directed to the floor. The
system will still try to keep the interior of the vehicle at
the previously chosen temperature setting. The outside
temperature will be shown on the display when the
system is off.
The ventilation system always allows outside air to flow
through your vehicle when the vehicle is moving, even
with the system in the OFF mode.

3-4
AUTO (Automatic Climate Control): Press the AUTO
button when you want the system to automatically
maintain a set temperature. When the system is set for
automatic operation, air will come from the floor ducts,
instrument panel outlets or windshield outlets depending
on the temperature inside the vehicle, the outside
temperature and the sun load. Sun and temperature
sensors automatically adjust the air temperature, the
airflow direction and the fan speed to maintain your
comfort setting. The system may supply cooler air to the
side of the vehicle toward the sun. Be careful not to put
anything over the sensors on top of the dash.
To find your preferred temperature setting, start with the
system in AUTO mode and the temperature set at 75
F
(24
C). Give the vehicle about 20 minutes to stabilize,
and adjust your the temperature setting, if necessary,
using the TEMP button. The display will show the
selected temperature, fan speed and airflow direction for
a few seconds, and then it will display the outside
temperature. If you choose a temperature setting of 60
F
(15
C), the system will remain at the maximum cooling
setting and fan speed. If you choose a temperature
setting of 90
F (33
C), the system will remain at the
maximum heat setting and fan speed. Choosing either
maximum setting will not cause the system to heat or
cool any faster.In cold weather, the system will delay turning the fan
on high, to avoid blowing cold air into the vehicle. The
length of the delay depends on the engine coolant
temperature and the outside temperature. Pressing the
FAN, AIR FLOW or FRONT buttons will override
this delay, turn off the AUTO setting and change the
fan speed.
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.
On very hot days, the automatic system will enter the
recirculation mode and the temperature door will be
positioned at the full cold position for maximum cooling
for as long as necessary to reach the set temperature.
You can choose the extreme temperature setting of
60
F (15
C), but the system will not cool any faster.

following reasons:
E10: The tape is tight and the player can't turn the
tape hubs. Remove the tape. Hold the tape with the
open end down and try to turn the right hub
counterclockwise with a pencil. Turn the tape over
and repeat. If the hubs do not turn easily, your tape
may be damaged and should not be used in the
player. Try a new tape to make sure your player is
working properly.
E11: The tape is broken. Try a new tape.
CLN (Clean): If this message appears on the display,
the cassette tape player needs to be cleaned. It will still
play tapes, but you should clean it as soon as possible to
prevent damage to the tapes and player. See ªCare of
Your Cassette Tape Playerº in the Index.
If any error occurs repeatedly or if an error can't be
corrected, contact your dealer. If your radio displays an
error number, write it down and provide it to your dealer
when reporting the problem.
