2003 BUICK LESABRE Light button

Twilight Sentinelž
Twilight Sentinelžturns your headlamps on and off by
sensing how dark it is outside.
The lever for this feature is
located to the left of the
steering column.
To operate it, leave the exterior lamp button off.
If you slide the lever all the way to MAX, your
headlamps will remain on for about three minutes after
you turn off your engine. As you slide the lever
toward OFF, the headlamps will turn off more quickly.
You can change this delay time from only a few seconds
to three minutes.
The exterior lamps can be completely shut off while the
vehicle is in PARK (P) by sliding the Twilight Sentinel
ž
lever all the way to OFF. To turn the exterior lamps back
on, slide the lever toward MAX again, or shift out of
PARK (P).
Park Lamp Override Feature
If the Twilight Sentinelžlighting is active, it can be
disabled by turning on the manual parking lamps. The
lighting will be disabled until the ignition is moved
from RUN or until the outside light level becomes
daylight. The outside light level changing to daylight will
cause the Twilight Sentinel
žfeature to deactivate.
The wiper-activated headlamps will override the twilight
disable feature.
Light Sensor
Your Twilight Sentinelž
and DRL work with the
light sensor located on top
of the instrument panel.
Don't cover it up. If you do, the sensor will read ªdarkº
and the Twilight Sentinel
žlighting will turn on.

Exterior Lighting Battery Saver
If the exterior lamp button has been left on, the exterior
lamps will turn off approximately 10 minutes after the
ignition is turned to LOCK and any door has been
opened. This protects against draining the battery in
case you have accidentally left the headlamps or parking
lamps on. If you need to leave the lamps on for more
than 10 minutes, use the manual control to turn the
lamps back on after the ignition is turned to LOCK and
any door is opened. To delay the lamps from turning
off, see ªTwilight Sentinel
žº underExterior Lamps
on page 3-14.
Interior Lamps
Instrument Panel Brightness
The lever for this feature is
located to the left of the
steering column.
The brightness of the instrument panel lights can be
adjusted by sliding the INTERIOR lever from LO to HI.
The instrument panel lights will be on only while the
parking lamps are on. The interior courtesy lamps can
be turned on by sliding the INTERIOR lever all the
way to HI.

Courtesy Lamps
If it is dark enough outside, when any door is opened,
several lamps go on. They make it easy for you to enter
and leave the vehicle. You can also turn these lamps
on by sliding the INTERIOR lever all the way to the top.
Entry Lighting
If it is dark enough outside when you press the unlock
button on the remote keyless entry transmitter, the
interior courtesy lamps will turn on and stay on
for approximately 40 seconds. The lamps will turn off
immediately by pressing the lock button on the remote
keyless entry transmitter, turning the ignition key to

Delayed Entry Lighting
If it is dark enough outside when you open the door, the
interior lamps will turn on. When you close the door
with the ignition off, the interior lamps will stay on for up
to 25 seconds or until the ignition is turned to an on
position. When the lamps turn off as a result of
the 25 second timer or the ignition switch being turned
on, the lighting will deactivate via the theater dimming
effect. Locking the doors will override the delayed entry
lighting feature and the lamps will turn off right away.
Theater Dimming
This feature allows for a three to ®ve-second fade out of
the courtesy lamps instead of immediate turn off.
Delayed Exit Lighting
If it is dark enough outside when you remove the key
from the ignition, the interior lamps will turn on and stay
on for approximately 25 seconds. This will give you
time to ®nd the door pull handle or lock switches. Once
the key is inserted into the ignition the exit lighting
will be cancelled and the lighting will fade out.
Perimeter Lighting
If it is dark enough outside when the unlock button on
the remote keyless entry transmitter is pressed, the
DRL, parking lamps and back-up lamps will come on.

Climate Controls
Climate Control System
With this system you can control the heating, cooling
and ventilation for your vehicle.
TEMPERATURE:This lever is used to adjust the
temperature of the air coming through the system.
Moving the lever between COOL and WARM will change
the temperature of the air coming through your outlets.
9FAN:Move this lever to select the speed of
the fan. Moving the lever between LOW and HIGH will
decrease or increase the fan speed. The fan will be
off when the system is off.To change the current mode, select one of the following:
RECIRC (Recirculation):This mode keeps outside
air from coming in the vehicle. It can be used to prevent
outside air and odors from entering your vehicle or to
help heat or cool the air inside your vehicle more quickly.
Press this button to turn the recirculation mode on or
off. When the button is pressed, an indicator light
will come on. You may not use RECIRC with FRONT
defrost or BLEND.
VENT:This mode directs air to the instrument panel
outlets.
HTR (Heater):This mode directs most of the air to the
¯oor outlets with some air directed to the outboard
outlets (for the side windows) and some air directed to
the windshield.
BLEND:This mode splits the air¯ow between the
windshield and the ¯oor outlets. The air conditioning
compressor will be operating.
OFF:The ventilation system always allows fresh air to
¯ow through your vehicle when it is moving. The
system will try to keep the air at a previously chosen
temperature. When the system is off, the blower fan is
also off.
MAX (Maximum Air Conditioning):This mode directs
air¯ow through the instrument panel outlets. The
amount of outside air entering your vehicle is limited.
3-24

Also in this mode, the RECIRC function is activated to
create the maximum cooling effect in the vehicle. If
RECIRC was activated before selecting MAX, the light
in the RECIRC button will go off. If RECIRC is
selected after MAX, the light in the RECIRC button will
not come on.
NORM (Normal Air Conditioning):This mode cools
the outside air entering your vehicle and directs it
through the instrument panel outlets.
BI-LEV (Bi-Level Air Conditioning):This mode directs
approximately half of the air to the instrument panel
outlets, and then directs most of the remaining air to the
¯oor outlets. Some air may be directed toward the
windshield. Cooler air is directed to the upper outlets
and warmer air to the ¯oor outlets. The air conditioning
compressor is on in this mode.
On hot days, open the windows to let hot inside air
escape; then close them. This helps to reduce the time
it takes for your vehicle to cool down. It also helps
the system to operate more efficiently.
For quick cool down on hot days, do the following:
1. Select the vent mode.
2. Select the recirculation mode.
3. Select MAX.
4. Select the coolest temperature.
5. Select the highest fan speed.Using these settings together for long periods of time
may cause the air inside of your vehicle to become too
dry. To prevent this from happening, after the air in
your vehicle has cooled, turn the recirculation mode off.
The air conditioning system removes moisture from
the air, so you may sometimes notice a small amount of
water dripping underneath your vehicle while idling or
after turning off the engine. This is normal.
Sensors
The solar sensor on your vehicle monitors the solar
radiation and the air inside of your vehicle, then uses the
information to maintain the selected temperature by
initiating needed adjustments to the temperature, the fan
speed and the air delivery system. The system may
also supply cooler air to the side of the vehicle facing the
sun. The recirculation mode will also be activated, as
necessary. Do not cover the solar sensor located in the
center of the instrument panel, near the windshield,
or the system will not work properly.
Defogging and Defrosting
Fog on the inside of windows is a result of high humidity
(moisture) condensing on the cool window glass. This
can be minimized if the climate control system is
used properly. This mode allows you to clear fog or
frost from your windshield.
3-25

MID:This mode directs air¯ow through the instrument
panel outlets.
MID-FLOOR:This mode directs air¯ow through both
the ¯oor and the instrument panel outlets. There is also
a small amount of air directed to the windshield and
the outboard outlets (for the side windows).
FLOOR:This mode directs most of the air¯ow to the
¯oor outlets with some directed to the outboard
outlets (for the side windows) and the windshield.
OFF:Press the OFF button once to turn off the
passenger climate control, if it has been activated.
Pressing the OFF button a second time will turn off the
main system. The outside temperature will be shown
on the display when the system is off.
VENT (Flow-Through Ventilation):Pressing the VENT
button allows outside air to ¯ow through your vehicle
without the air conditioning compressor working. To turn
off the VENT selection, push the VENT button again.
Selecting the VENT and AUTO buttons at the same time
allows the system to control the air¯ow automatically
without using the air conditioning compressor or
the recirculation mode.RECIRC (Recirculation):Press this button to limit the
amount of outside air coming into the vehicle. It can
be used to prevent outside air and odors from entering
your vehicle or to help heat or cool the air inside
your vehicle more quickly. Press this button to turn the
recirculation mode on or off. When the button is
pressed, an indicator light will come on. The recirculation
mode cannot be used with the FRONT defrost or
VENT mode.
On hot days, open the windows to let hot air escape;
then close them. This helps to reduce the time it takes
for your vehicle to cool down. It also helps the system
to operate more efficiently.
For quick cool down on hot days, press the AUTO
button and the system will automatically enter
recirculation mode and the temperature will be at the full
cold position for maximum cooling.
Using these settings together for long periods of time
may cause the air inside of your vehicle to become too
dry. To prevent this from happening, after the air in
your vehicle has cooled, turn the recirculation mode off.
The air conditioning system removes moisture from
the air, so you may sometimes notice a small amount of
water dripping underneath your vehicle while idling or
after turning off the engine. This is normal.

To recall the climate control settings last stored on your
transmitter, press the unlock button on your remote
keyless entry transmitter and put the ignition in
ACCESSORY or RUN. The settings will be recalled.
Warning Lights, Gages and
Indicators
This part describes the warning lights and gages that
may be on your vehicle. The pictures will help you
locate them.
Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause
an expensive repair or replacement. Paying attention to
your warning lights and gages could also save you
or others from injury.
Warning lights come on when there may be or is a
problem with one of your vehicle's functions. As you will
see in the details on the next few pages, some
warning lights come on brie¯y when you start the
engine just to let you know they're working. If you are
familiar with this section, you should not be alarmed
when this happens.Gages can indicate when there may be or is a problem
with one of your vehicle's functions. Often gages
and warning lights work together to let you know when
there's a problem with your vehicle.
When one of the warning lights comes on and stays on
when you are driving, or when one of the gages
shows there may be a problem, check the section that
tells you what to do about it. Please follow this
manual's advice. Waiting to do repairs can be
costly ± and even dangerous. So please get to know
your warning lights and gages. They're a big help.
Your vehicle may also have a DIC that works along with
the warning lights and gages. See
Driver Information
Center (DIC) on page 3-45.
The volume of your vehicle's warning chimes can be
adjusted. For information see
Chime Level Adjustment
on page 3-81.
