2009 BUICK LUCERNE panel

Wiper Activated Headlamps
This feature activates the headlamps and parking lamps
after the windshield wipers are turned on and have
completed eight wipe cycles within four minutes.
When the ignition is turned to LOCK/OFF, the
wiper-activated headlamps immediately turn off.
The wiper-activated headlamps also turn off if the
windshield wipers are turned off.
Headlamps on Reminder
If you leave the exterior lamp buttons for the headlamps
or parking lamps on, remove the key from the ignition
and open the driver’s door, you will hear a continuous
warning chime. The chime will turn off when the
lamps are turned off.
Daytime Running Lamps (DRL)
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the day.
Fully functional daytime running lamps are required
on all vehicles rst sold in Canada.
A light sensor on top of the instrument panel monitors
the exterior light level for the operation of DRL, so
be sure it is not covered.The DRL system makes the low-beam headlamps
turn on at reduced brightness in daylight when
the following conditions are met:
The ignition is on.
The exterior lamp button for the headlamps is off.
The automatic transmission is not in P (Park).
When the DRL are on, only the low-beam headlamps
will be on. The parking lamps, taillamps, sidemarker and
other lamps will not be on.
When it is dark enough outside, the low-beam
headlamps will come on. The other lamps that turn
on with the headlamps will also turn on. When it is bright
enough outside, the regular lamps will go off, and the
low-beam headlamps change to the reduced brightness
of DRL.
To turn off all exterior lighting at night when the vehicle
is parked, turn the exterior lamp control to the off position.
The exterior lamps will turn back on automatically when
the transmission is moved out of P (Park). SeeExterior
Lamps on page 3-15for more information.
The regular headlamp system should be turned on
when needed.

Fog Lamps
For vehicles with fog lamps, the button is located on
the exterior lamps control. The exterior lamps control is
located on the instrument panel to the left of the steering
column.
#(Fog Lamps):Press the exterior lamps button
to turn the fog lamps on or off. A light comes on in the
instrument panel cluster to show that the fog lamps
are on. SeeInstrument Panel Cluster on page 3-33.
The ignition must be in the ON/RUN position and
the parking lamps must be on for the fog lamps to
illuminate.
The fog lamps will go off while you change to high-beam
headlamps.
Some localities have laws that require the headlamps to
be on along with the fog lamps.
Cornering Lamps
For vehicles with this feature, the cornering lamps come
on when: the headlamps or parking lamps are on, the
vehicle is not in P (Park), and you signal a turn with
the turn signal/multifunction lever. They provide
more light for cornering.
Exterior Lighting Battery Saver
If the exterior lamp button has been left on, the exterior
lamps will turn off about 10 minutes after the ignition is
turned to LOCK/OFF and a door has been opened. This
protects against draining the battery if the headlamps or
parking lamps are accidentally left on. If you need to
leave the lamps on for more than 10 minutes, use the
exterior lamp control to turn the lamps back on after the
ignition is turned to LOCK/OFF and any door is opened.
Instrument Panel Brightness
D(Instrument Panel Brightness):This feature
controls the brightness of the instrument panel lights.
The knob for this control is located next to the exterior
lamps control.
Push the knob in and release when it pops out.
Turn the knob clockwise to increase the brightness
of the instrument panel lights and counter clockwise to
decrease the brightness. Turning the knob completely
clockwise to the detent will turn on the courtesy lamps.

Courtesy Lamps
When any door is opened, several lamps turn on
making it easier for you to enter and exit the vehicle.
Turn the instrument panel brightness control completely
clockwise to manually turn on these lamps.
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 about
40 seconds. The lamps can be turned off immediately by
pressing the lock button on the remote keyless entry
transmitter, turning the ignition key to ON/RUN or
activating the power door locks.
Delayed Entry Lighting
The interior lamps will turn on if you open the door when
it is dark enough outside. 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 by way of 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 about 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.
This feature can be programmed on for various amounts
of time in seconds for each transmitter.

AUTO (Automatic Mode)
1. Turn the fan control to AUTO.
2. Turn the mode control to AUTO.
3. Adjust the temperature to a comfortable setting
between 68°F (21°C) and 78°F (26°C).
Choosing the coldest or warmest temperature
setting will not cause the system to heat or cool any
faster. In cold weather, the system starts at reduced
fan speeds to avoid blowing cold air into the vehicle
until warmer air is available. The system will start
out blowing air to the oor, but may change modes
automatically as the vehicle warms up to maintain
the chosen temperature setting. The length of time
needed to warm the interior depends on the outside
temperature.
4. Wait a few minutes for the system to automatically
regulate. Then adjust the temperature as necessary
to nd your comfort setting.
Do not cover the solar sensor located in the center of
the instrument panel, near the windshield. For more
information on the solar sensor, see “Sensors” later in
this section.

Operation Tips

Clear away any ice, snow, or leaves from the air
inlets at the base of the windshield that could
block the ow of air into the vehicle.
Use of non-GM approved hood deectors can
adversely affect the performance of the system.
Keep the path under the front seats clear of objects
to help circulate the air inside the vehicle better.
Passenger Compartment Air Filter
Outside air is routed through a passenger compartment
air lter before entering the vehicle. This lter removes
certain particles from the air, including pollen and dust
particles. The lter should be replaced as part of routine
scheduled maintenance. SeeScheduled Maintenance
on page 6-4for when to replace the lter.
The access panel for the passenger compartment air
lter is located under the hood near the windshield,
on the passenger’s side of the vehicle.
