light BUICK LESABRE 2005 Owner's Guide

You may also have an arrow in the outside mirror that
ashes when the turn signal is used. SeeOutside Power
Mirrors on page 2-35for more information.
Raise or lower the lever until the arrow starts to ash to
signal a lane change. Hold it there until the lane
change is complete.
If the arrows ash very fast as you signal a turn or a
lane change, a signal bulb may be burned out and other
drivers will not see your turn signal. If a bulb is burned
out, replace it to help avoid an accident.
If the arrows do not go on at all when you signal a turn,
check the fuse. SeeFuses and Circuit Breakers on
page 5-88.
Turn Signal On Chime
If your turn signal is left on for more than 0.8 miles
(1.3 km), a chime will sound at each ash of the turn
signal. To turn off the chime, move the turn signal lever
to the off position.
Headlamp High/Low-Beam Changer
To change the headlamps from low beam to high
beam or high beam to low beam, pull the turn signal
lever toward you and release it.
While the high beams are
on, this light located on the
instrument panel cluster
will also be on.
If your vehicle is equipped with the Head-Up Display
(HUD), this symbol will also appear in the display area to
indicate the high beams are on. SeeHead-Up Display
(HUD) on page 3-20for more information.
Flash-to-Pass
This feature lets you use the high-beam headlamps to
signal the driver in front of you that you want to pass. It
works even if your headlamps are off.
Pull the turn signal lever toward you briey to
ash-to-pass.
If the headlamps are off or on low beam, the high-beam
headlamps will turn on. They will stay on as long as
you hold the lever toward you and the high-beam
indicator on the instrument panel cluster will come on.

Windshield Wipers
The windshield wipers are controlled by turning the
band marked WIPER.
If your windshield wipers are on for more than
six seconds while you are driving, the low-beam
headlamps, instrument panel cluster backlighting and
taillamps will turn on. For more information see
Wiper Activated Headlamps on page 3-14.
OFF:Turn the band to OFF to turn the wipers off.
MIST:For a single wiping cycle, turn the band to MIST.
Hold it there until the wipers start, then let go. The
wipers will stop after one cycle. If you want more cycles,
hold the band on MIST longer.
LO (Low Speed):Turn the band to LO for steady
wiping at a slow speed.
HI (High Speed):Turn the band to HI for steady wiping
at a high speed.
The wiper speed may be set for a long or short delay
between wipes. Turn the band to choose the delay time.
The closer to LO, the shorter the delay.Heavy snow or ice can overload your wiper motor. A
circuit breaker will stop the motor until it cools.
Clear away snow or ice to prevent an overload.
Keep in mind that damaged wiper blades may prevent
you from seeing well enough to drive safely. To
avoid damage, be sure to clear ice and snow from the
wiper blades before using them. If your blades do
become damaged, get new blades or blade inserts.
Rainsense™II Wipers
If your vehicle has this feature, the moisture sensor is
mounted on the interior of the windshield below the
rearview mirror and is used to automatically operate the
wipers. This system operates by monitoring the
amount of moisture build-up on the windshield. Wipes
occur as needed to clear the windshield depending
on the driving conditions and the sensitivity setting. In
light rain or snow, fewer wipes will occur. In heavy
rain or snow, wipes will occur more frequently.
The system will operate in the delay, low speed and
high speed modes. If the system is left on for long
periods of time, occasional wipes may occur without any
moisture on the windshield. This is normal and
indicates that the Rainsense™ system is active.

When you take your foot off the pedal, your vehicle will
slow down to the cruise control speed you set earlier.
Using Cruise Control on Hills
How well your cruise control will work on hills depends
upon your speed, load and the steepness of the
hills. When going up steep hills, you may have to step
on the accelerator pedal to maintain your speed.
When going downhill, you may have to brake or shift to
a lower gear to keep your speed down. Applying the
brake or shifting into a lower gear will take your vehicle

Daytime Running Lamps (DRL)
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the
day. DRL can be helpful in many different driving
conditions, but they can be especially helpful in the short
periods after dawn and before sunset. 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 and
Twilight Sentinel
®, so be sure it is not covered.
The DRL system will make your 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 transaxle is not in PARK (P).
When the DRL are on, only your low-beam headlamps
will be on. The parking lamps, taillamps, sidemarker
and other lamps will not be on.When it is dark enough outside, your low-beam
headlamps will come on. The other lamps that turn on
with your headlamps will also turn on. When it is
bright enough outside, the regular lamps will go off, and
your low-beam headlamps change to the reduced
brightness of DRL.
To turn off all exterior lighting at night when you are
parked, turn off the headlamps and move the Twilight
Sentinel
®lever all the way toward OFF. The exterior
lamps will turn back on automatically when you move
the transaxle out of PARK (P).
As with any vehicle, you should turn on the regular
headlamp system when you need it.

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
®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).

Light Sensor
Your Twilight
Sentinel®and DRL work
with the light sensor
located on top of the
instrument panel.
Do not cover it up. If you do, it will sense darkness and
the Twilight Sentinel
®lighting will turn on.
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 and a 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

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
