2002 BUICK LESABRE Owner's Manual

3-4 Dual Automatic ComforTemp
Climate Control (If Equipped)
TEMP (Temperature): To manually adjust the
temperature inside the vehicle, push the TEMP arrow.
Push the TEMP up arrow for warmer temperature
settings and the TEMP down arrow for cooler
temperature settings. The setting will be shown in the
display. The display will then return to the outside
temperature after a few seconds.
FAN: Pressing the FAN button will display and
hold the current fan speed while in manual mode.If you want the fan to run at a lower speed, push the
down arrow on 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 up arrow on the FAN button.
AIR FLOW: Pressing the AIR FLOW button will
display and hold the current setting while in manual
mode. Use the up and down arrows on the AIR FLOW
button to cycle through the available modes.

WINDSHIELD
-FLOOR: This setting directs
most of the airflow to the front windshield defroster
with some airflow to the side window defrosters and
floor ducts.

MID: This setting directs airflow through the
instrument panel outlets.

MID
-FLOOR: This setting directs airflow through
both the instrument panel outlets and the floor ducts.
There is also a small amount of air directed to the
front defroster and the side window defrosters.

FLOOR: This setting directs most of the airflow to
the floor ducts with some airflow directed to the side
window defrosters. There is also a small amount of
airflow directed to the front defroster.

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 toward the
floor. The system will still try to keep the interior of the
vehicle at the previously chosen temperature 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
when the system is off.
VENT (Flow
-Through Ventilation): The VENT
button allows outside air to flow through your vehicle
without the air conditioning compressor working. To
turn off the VENT selection, push the VENT button
again. If you select VENT while in FRONT defrost, the
VENT light will flash three times to let you know this is
not allowed. This is to prevent fogging.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. RECIRC and AUTO
may be selected at the same time. The system will remain
in RECIRC until the ignition is turned off or the RECIRC
button is pressed again. RECIRC can be selected in all
manual airflow modes except FRONT defrost and VENT.
If you select RECIRC while in FRONT defrost, the
RECIRC light will flash three times to let you know this is
not allowed. This is to prevent fogging. FRONT: This selection is used to defrost
the windshield by directing the airflow toward the
windshield. To turn off FRONT, press the AUTO
or AIR FLOW button.
If the AIR FLOW up button is selected while in the
FRONT defrost mode, the system will direct the air
toward the windshield and the floor. 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.
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.

3-6 Passenger Climate Control (If Equipped)
If your vehicle is equipped with the Dual Automatic
ComforTemp system, the front seat passenger can
control the air temperature in his or her seating area. The
control is located on the passenger's door armrest.The temperature can be set up to 5
F (3
C) cooler
or warmer than the primary setting. To activate the
passenger control, press the button with the red arrow
to increase temperature. Each time you press the button, a
red indicator light will come on. To decrease temperature,
press the button with the blue arrow. Each time you press
the button a blue indicator light will come on.
If the passenger control has been turned on, it can be
turned off by pressing the OFF button on the main
system once. (Pressing the OFF button a second time
will turn off the main system.)
Automatic Operation
Press the AUTO button when you want the system to
automatically maintain a selected temperature inside of
your vehicle. 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 sun load. Fan speed and use of air conditioning and
recirculation will vary as needed.

3-7
Sun and temperature sensors automatically adjust the air
temperature, the airflow direction and the fan speed to
maintain your temperature setting. The system may
supply cooler air to the side of the vehicle toward the
sun. Be careful not to put anything over the sensor on
top of the dash.
The display will show fan speed, temperature level
setting and airflow direction for a few seconds whenever
AUTO is selected, and then it will display the outside
temperature. The outside temperature reading is most
accurate when the vehicle is moving. During stops, the
display shows the previous temperature for best
accuracy and system control.
To find your preferred temperature setting, start with the
system in AUTO mode and the TEMP button adjusted
to 75
F (24
C), give the vehicle about 20 minutes to
stabilize, and adjust your temperature setting if
necessary, by using the TEMP button. The display will
show the temperature setting for a few seconds and then
it will display the outside temperature. If you want to
see your current automatic fan speed, airflow direction
and temperature setting, press the AUTO button.In cold weather, the system will delay turning on the fan,
to avoid blowing cold air. During this delay the system
will be in FRONT defrost mode and the light in the button
will come on and stay on as long as the display is showing
the current mode, set TEMP and FAN speed. This light
will go off when the display returns to the outside
temperature. 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 return
the system to manual operation.
Personal Choice Comfort Controls
(If Equipped)
This feature enables up to two drivers to store and recall
comfort control settings for the temperature, fan speed
and the direction of the airflow.
The memory buttons (1 or 2) for this feature are located
on the driver's door panel and correspond to the
numbers (1 or 2) found on the back of each keyless
entry transmitter.
To recall comfort settings, press the unlock button on the
remote keyless entry transmitter and put the ignition in
ACCESSORY or RUN. The climate control setting last
chosen by the identified driver (1 or 2) will be recalled.

3-8
To program a personal choice climate control setting,
do the following:
1. Choose a temperature setting for the driver and if
desired, for the passenger. See ªDual Automatic
ComforTemp

Climate Controlº and ªPassenger
Climate Controlº earlier in this section.
2. Adjust the fan speed and the direction of the airflow.
3. Locate the memory buttons on the driver's
door panel.
4. Press a memory button (1 or 2) until you hear two
beeps. The beeps confirm that your selection has
been saved and can now be recalled.
Follow these steps each time you want to change the
stored settings. For more information on the memory
feature, see ªMemory Seat and Mirrorsº in the Index.
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.
If you have the electronic touch system, for quick
cool
-down on very hot days, use maximum air
conditioning with the temperature and fan speed
adjusted to COOL and HIGH. If this setting is used
for long periods of time, the air in your vehicle may
become too cold and dry.
For normal cooling on hot days, use Normal and
adjust the temperature and fan speed for your comfort.
If Recirculation is selected while in the Normal air
conditioning mode, the system works like maximum
air conditioning and recirculates the air.

3-9
On sunny days, when the air is moderately warm or
cool, use Bi
-Level to deliver warm air to the floor ducts
and cooler air to the instrument panel outlets. On days
like these, the sun may adequately warm your upper
body, but your lower body may not be warm enough.
To warm or cool the air delivered, adjust the
TEMPERATURE lever.
The amount of fresh air entering the vehicle is limited
when Recirculation is selected. This is helpful when you
are trying to cool the air in your vehicle or limit the air
entering the vehicle.
If your vehicle has the Dual Automatic ComforTemp
system and it is set for Automatic Operation, on very hot
days, the system will automatically enter recirculation
mode and the temperature door will be positioned at the
full cold position for maximum cooling. If the system is
not in the automatic mode, recirculation should be
selected to provide maximum cooling. You can choose
the extreme comfort setting of 60
F (16
C), but the
system will not cool any faster as a result.Heating
If your vehicle has the electronic touch system, on cold
days, use HTR with the TEMPERATURE lever toward
WARM and the fan speed toward HIGH.
If your vehicle has the Dual Automatic ComforTemp
system, and on cold days, if the automatic mode is
selected, the system will automatically direct the air
toward the floor and the temperature door will be
positioned at the full hot position. You can choose the
extreme comfort setting of 90
F (32
C) but the
system will not warm up any faster as a result. If the
outside temperature is cold, the fan will be delayed to
avoid blowing cold air. Pushing the FAN, AIR FLOW
or FRONT buttons will override this delay, turn off
the automatic mode and return the system to
manual operation.
With each system, outside air will be brought in and sent
through the floor ducts. The heater works best if you
keep your windows closed while using it.

3-10 Defogging and Defrosting
If you have the electronic touch system, press the
FRONT button and adjust the TEMPERATURE lever
toward WARM and the FAN lever toward HIGH.
If you have the Dual Automatic ComforTemp
system,
use the FRONT button to defog or defrost the
windshield. By choosing this button, the airflow will be
directed at the windshield. Adjust your temperature
level by pressing the TEMP up or down arrow. The fan
speed will be controlled by the system. You can change
the fan speed by pressing the up FAN arrow to increase
speed, and the down arrow to decrease speed.
To reduce the chance of fogging your windows in cold
weather, using the electronic touch system, select HTR
to supply air through the floor ducts. Then move the
FAN lever to HIGH for a few moments before driving
away. This will blow moist air from the intake outlets
toward the floor, not the windshield. If you have the
Dual Automatic ComforTemp system, the AUTO setting
will do this for you. Manual operation of the automatic
ComforTemp system in the floor mode will also supply
air through the floor ducts.
Rear Window Defogger
The lines you see on the
rear window warm the
glass. Press this button to
start warming your rear
and side windows.
At speeds above 35 mph (55 km/h), the defogger
will operate continuously until you press the REAR
button again. After 10 minutes of driving below 35 mph
(55 km/h), the defogger will turn off automatically. If
you need additional warming time, push the button
again. The system will then operate for five minutes
before going off by itself.

3-11
NOTICE:
Do not try to clear frost or other material from
the inside of the rear window with a razor blade
or anything else that is sharp. This may damage
the rear defogger grid. The repairs wouldn't be
covered by your warranty.
Do not attach a temporary vehicle license, tape or decals
across the defogger grid on the rear window.
Ventilation System
For mild outside temperatures when little heating
or cooling is needed, use VENT (on the electronic
touch system or manual operation on the Dual
Automatic ComforTemp
system) to direct
outside air through your vehicle. Air will flow
through the instrument panel outlets.
Your vehicle's flow
-through ventilation system supplies
outside air into the vehicle while it's moving. While the
vehicle is not moving, you can get outside air to flow
through by selecting any air choice (except the rear
window defogger) and any fan speed.
Adjust the direction of
airflow by moving the
louvered vents.
If you have the optional rear
passenger ComforTemp,
you can adjust the direction
of the airflow to the rear
seating area.
