2007 BUICK LUCERNE headlamp

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
You control the windshield wipers by turning the
band with the wiper symbol on it.
8(Mist):Turn the band to mist for a single wiping
cycle. Hold it there until the wipers start. Then let
go. The wipers stop after one wipe. For more wipe
cycles, hold the band longer on mist.
6(Delay):Turn the band to choose the delay time
between wipe cycles. The wiper speed can be set
for a long or short delay between wipes. The closer
the band is set to the top of the lever, the shorter
the delay.
6(Low Speed):Turn the band away from
you to the rst solid band past the delay settings
for steady wiping at low speed.
1(High Speed):For high-speed wiping, turn
the band further, to the second solid band past the
delay settings.
9(Off):To stop the wipers, move the band to off.
Clear ice and snow from the wiper blades before
using them. If they are frozen to the windshield,
carefully loosen or thaw them. If the blades
become worn or damaged, replace with new
blades or blade inserts.
Heavy snow or ice can overload the wiper motor. A
circuit breaker will stop the motor until it cools. Clear
away snow or ice to prevent an overload.
Your vehicle has wiper-activated headlamps. After
the windshield wipers have completed eight
wipe cycles within four minutes, the headlamps
automatically turn on. SeeWiper Activated
Headlamps on page 171for more information.

Using Cruise Control on Hills
How well the cruise control will work on hills
depends upon the vehicle 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. Of course, applying the
brake ends the cruise control. Many drivers
nd this to be too much trouble and do not use
cruise control on steep hills.
Ending Cruise Control
There are three ways to end cruise control:
Step lightly on the brake pedal.
Press the[(cancel) button on the steering
wheel.
Press theT(on/off) button on the steering
wheel.
Erasing Speed Memory
The cruise control set speed memory is erased by
turning off the cruise control or the ignition.

The exterior lamps
control is located on
the instrument panel
to the left of the
steering wheel.
It controls the following systems:
Headlamps

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, 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 automatic 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 the exterior lamp control to the
off position. The exterior lamps will turn back
on automatically when you move the transaxle out
of PARK (P). SeeExterior Lamps on page 170
for more information.
As with any vehicle, you should turn on the
regular headlamp system when you need it.
172

Fog Lamps
-(Fog Lamps):If your vehicle has 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.
Your ignition must be in RUN for the fog lamps to
illuminate.
To turn the fog lamps on, press the exterior lamps
button. A light will come on in the instrument
panel cluster to let you know that the fog lamps
are on. SeeInstrument Panel Cluster on page 194.
Press the exterior lamps button again to turn the
fog lamps off.
The ignition must be in RUN and the parking
lamps must be on for your fog lamps to work.
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
If your vehicle has this feature, the cornering lamps
come on when: the headlamps or parking lamps are
on, the vehicle is not in PARK (P), 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 OFF 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
OFF and any door is opened.

Electric Power Management
The vehicle has Electric Power Management
(EPM) that estimates the battery’s temperature and
state of charge. It then adjusts the voltage for
best performance and extended life of the battery.
When the battery’s state of charge is low, the
voltage is raised slightly to quickly put the charge
back in. When the state of charge is high, the
voltage is lowered slightly to prevent overcharging.
If the vehicle has a voltmeter gage or voltage
display on the Driver Information Center (DIC),
you may see the voltage move up or down. This
is normal. If there is a problem, an alert will
be displayed.
The battery can be discharged at idle if the
electrical loads are very high. This is true for all
vehicles. This is because the generator (alternator)
may not be spinning fast enough at idle to produce
all the power that is needed for very high electrical
loads.A high electrical load occurs when several of the
following loads are on: headlamps, high beams, fog
lamps, rear window defogger, climate control fan at
high speed, heated seats, engine cooling fans,
trailer loads, and loads plugged into accessory
power outlets.
EPM works to prevent excessive discharge of the
battery. It does this by balancing the generator’s
output and the vehicle’s electrical needs. It can
increase engine idle speed to generate more
power, whenever needed. It can temporarily
reduce the power demands of some accessories.
Normally, these actions occur in steps or levels,
without being noticeable. In rare cases at the
highest levels of corrective action, this action
may be noticeable to the driver. If so, a Driver
Information Center (DIC) message might be
displayed, such as Battery Saver Active or Service
Battery Charging System. If this message is
displayed, it is recommended that the driver
reduce the electrical loads as much as possible.
SeeDIC Warnings and Messages on page 221.

Inadvertent Power Battery Saver
This feature is designed to protect your vehicle’s
battery against drainage from the interior lamps, or
garage door opener. When the ignition is turned
off, the power to these features will automatically
turn off after 10 minutes. Power will be restored
for an additional 10 minutes if any door is opened,
the trunk is opened or the courtesy lamp switch
is turned on.
Battery Run-Down Protection
This vehicle has a feature to help prevent the
battery from being drained, if the interior courtesy
lamps, reading/map lamps, visor vanity lamps
or trunk lamp are accidentally left on. If any
of these lamps are left on, they will automatically
turn off after 10 minutes, if the ignition is off.
The lamps will not come back on again until one
of the following occurs:
The ignition is turned on.
The exterior lamps control is turned off, then
on again.
The headlamps will timeout after 10 minutes, if they
are manually turned on before the ignition is off.
