2001 BUICK PARK AVENUE display

2-98
The HUD controls
are located in the
overhead console.
1. Start your engine and slide the HUD dimmer control
all the way up.
The brightness of the HUD image is determined by
whether the headlamps are on or off, and where you
have the HUD dimmer control set.
2. Adjust the seat to your driving position. Slide the
image height adjuster control all the way up, raising
the image as far as possible.
3. Now slide the image height adjuster control down so
the image is as low as possible but still in full view.
4. Slide the dimmer control downward until the HUD
image is no brighter than necessary.To turn the HUD display off, slide the dimmer control
all the way down.
If the sun comes out, the sky becomes cloudy, or if you
turn your headlamps on, you may need to adjust the
HUD brightness using the dimmer control. Polarized
sunglasses could make the HUD image harder to see.
To change the display from English to metric units,
push the ENG/MET button located to the left of the
steering column.
Care of the HUD
Clean the inside of the windshield as necessary to
remove any dirt or film that reduces the sharpness or
clarity of the HUD image.
To clean the HUD lens, spray household glass cleaner
on a soft, clean cloth. Gently wipe and dry the HUD
lens. Do not spray cleaner directly on the lens to avoid
cleaner leaking inside the unit.

2-99 If You Can't See The HUD Image When the
Ignition is On
If the ignition is on and you can't see the HUD image,
check to see if:

The headlamps are on.

Something is covering the HUD unit.

The HUD dimmer control is adjusted properly.

The HUD image is adjusted to the proper height.

A fuse is blown. See ªFuses and Circuit Breakersº in
the Index.
Keep in mind that your windshield is part of the
HUD system. If you ever have to have your windshield
replaced, be sure to get one that is designed for HUD or
your HUD image may look blurred or out of focus.
Ultrasonic Rear Parking
Assist (URPA) (Option)
Ultrasonic rear parking assist can help you to determine
how close an object is to your rear bumper within a
given area, making parking easier.
The URPA display is located inside the vehicle, above
the rear window. It has three color
-coded lights that can
be seen through the rearview mirror.
How the System Works
Ultrasonic rear parking assist 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 rear sensors located
on the bumper. When shifting into REVERSE (R) and
an object is detected, one of the following will occur:

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. 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. For cleaning
instructions, see ªCleaning Your Vehicleº in the Index.

Comfort Controls
This section tells you how to operate your
comfort controls.
With these systems, 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.
Personal Choice Comfort Controls
(If Equipped)
This feature allows two different drivers to store and
recall their own climate control settings for temperature,
air delivery mode, fan and passenger climate control
(on/off) status. The personal choice settings recalled are
determined by the transmitter used to enter the vehicle.
After the button with the unlock symbol on a remote
keyless entry transmitter is pressed, and the ignition is in
RUN, the climate control will adjust to the last settings
of the identified driver. The settings can also be changed
by pressing one of the MEMORY buttons (1 or 2)
located on the driver's door, until you hear two beeps.
When adjustments are made, the new settings are
automatically saved for that driver.
Dual Automatic ComforTemp

Climate Control
Your vehicle has the dual automatic ComforTemp
climate control system. The following information tells
you how it works.
You will hear a beep each time a button is pushed and a
small light on the button will indicate which buttons are
active. The lights are on all buttons except TEMP, FAN
and AIR FLOW. The display will show fan speed,
comfort level setting and airflow direction for a few
seconds whenever any button, except for rear defog, is
pushed, and then it will display the outside temperature.
The outside temperature reading is most accurate when
the vehicle is moving.

3-3
During stops, when driving slow, or when the engine is
first started after a short trip, the outside temperature
reading can be affected by road or engine heat. Also,
starting the engine within a short time after the vehicle
has been running will affect the reading. To ensure
proper automatic climate control operation, the outside
temperature display may not update as quickly
as expected.
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 toward the sun. Be careful not to
put anything over the sensors on top of the dash.
Temperature Button
To adjust the comfort level you want maintained inside
the vehicle, push the TEMP button. If you want a
warmer comfort level, push the red arrow. If you want a
cooler comfort level, push the blue arrow. Your comfort
setting is shown in the display.Fan Button
The speed of the blower fan is controlled automatically
if you have the system set for AUTO. Pressing the
FAN button will display and hold the current blower
fan setting.
If you want the blower fan to run at a lower speed, push
the bottom of the FAN button. The fan speed will
decrease with every push of the button until the lowest
speed is reached. If you want to increase the fan speed,
push the top of the FAN button. Notice the fan
indicators on the display.
Mode Controls
Press the AIR FLOW button to deliver air through the
floor, middle or windshield outlets. The system will stay
in the selected mode until the AUTO button is pushed.
Press the up or down arrow on the AIR FLOW button
to cycle through the available modes.

3-4
Automatic Operation
Press the AUTO button when you want the system to
automatically adjust to changes in the temperature.
When the system is set for automatic operation, air will
come from the floor, middle or windshield outlets
depending on the temperature inside the vehicle, the
outside temperature and sun load. Fan speed will vary as
the system gets to and maintains the comfort setting you
have selected through the use of the TEMP button.
To find your comfort setting, start with the system in
AUTO mode and the TEMP button adjusted to a display
of 75
F (24
C), give the vehicle about 20 minutes to
stabilize, and adjust your comfort setting if necessary, by
using the TEMP button. The display will show the
comfort setting, fan speed and airflow direction for a
few seconds, and then it will display the outside
temperature. If you choose the temperature setting of
60
F (15
C), the system will remain at the maximum
cooling setting and fan speed. If you choose the
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. The length of the delay
depends on the engine coolant temperature and the
outside temperature. Pushing the FAN, AIR FLOW or
FRONT buttons will override this delay, turn off the
AUTO setting and change the fan speed.
Manual Operation
You may also manually adjust the air delivery or
fan speed.
AIR FLOW: This button is used to change the direction
of the airflow. The airflow choices available are FLOOR,
FLOOR
-MID, MID and WINDSHIELD-FLOOR.
If the system is set for AUTO, pressing the AIR FLOW
button will display the current airflow direction, the
comfort setting and the fan speed. Press the AIR
FLOW up or down button again to change the
direction of the airflow.
If the AIR FLOW up button is selected while in the
FRONT defrost mode, the system will direct the air
toward the mid
-position. If the AIR FLOW down button
is selected while in the FRONT defrost mode, the
system will direct the air toward the FLOOR, and the
FRONT defrost mode will cancel. Notice the arrows in
the display.

3-5
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 previous chosen comfort setting. The outside
temperature will show on the display when the system
is off.
The ventilation system always allows fresh air to flow
through your vehicle when the vehicle is moving, even
with the system in the OFF mode.
VENT: The VENT button allows outside air to flow
through your vehicle without the air conditioning
compressor working. Selecting the VENT and the
AUTO buttons at the same time allows the system to
control the air flow automatically without the use of the
air conditioning compressor or the use of the RECIRC
mode. To turn off the VENT selection, push the VENT
button again.RECIRC: 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 RECIRC until the ignition is
turned off. The system will return back to the previously
selected mode when the car is turned back on. RECIRC
can be selected in all manual airflow modes except
FRONT defrost. RECIRC cannot be selected with the
VENT button.
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 from the front defroster
will vary. If a manual fan speed setting is selected, the
fan speed will remain at that selection until another fan
speed selection is made or the AUTO mode is selected.
To turn off FRONT, press the AUTO or AIR
FLOW button.
FRONT defrost will work better if any ice or snow is
cleared from the hood and the air inlet area between the
base of the windshield and the hood.
