2007 BUICK LUCERNE battery light

Ignition Positions
With the ignition key in the ignition, the key can be
turned to four different positions:
Notice:Using a tool to force the key from the
ignition switch could cause damage or break
the key. Use the correct key and turn the key
only with your hand. Make sure the key is in all
the way. If none of this works, then your vehicle
needs service.A (OFF):This is the only position in which the
ignition key can be inserted or removed. This
position locks the ignition and transaxle. It is a
theft-deterrent feature.
B (ACCESSORY):This position lets the radio
and windshield wipers operate while the engine is
off. To use ACCESSORY, turn the key clockwise.
C (RUN):This position is where the key returns
to after the vehicle is started. This position displays
some of the warning and indicator lights.
The battery could be drained if you leave the key in
the ACCESSORY or RUN position with the engine
off. You may not be able to start your vehicle if the
battery is allowed to drain for an extended period
of time.
D (START):This position starts the engine.
A warning chime will sound and the Driver
Information Center (DIC) will display DRIVER
DOOR OPEN when the driver’s door is opened if
the ignition is in OFF, ACCESSORY and the key is
in the ignition. SeeDIC Warnings and Messages on
page 221for more information.

Key In the Ignition
Never leave your vehicle with the keys inside, as it
is an easy target for joy riders or thieves. If you
leave the key in the ignition and park your vehicle,
a chime will sound, when you open the driver’s
door. Always remember to remove your key from
the ignition and take it with you. This will lock
your ignition and transaxle. Also, always remember
to lock the doors.
The battery could be drained if you leave the
key in the ignition while your vehicle is parked.
You may not be able to start your vehicle after
it has been parked for an extended period of time.
Retained Accessory Power (RAP)
After you turn the ignition off and remove the key,
you will still have power to such accessories as the
power windows, clock, radio, and if equipped, audio
steering wheel controls and sunroof. The power
to the accessories can last up to 10 minutes. The
instrument panel cluster lights will stay on for a
few seconds, then will go out. Once you open the
driver’s door, the power will shut off. Your vehicle
has a feature designed to protect the battery
against drainage. For more information see
Inadvertent Power Battery Saver on page 177
andElectric Power Management on page 176.

OnStar®service that involves location information
about your vehicle cannot work unless GPS
satellite signals are unobstructed and available in
that place as well.
Your vehicle must have a working electrical
system (including adequate battery power) for the
OnStar
®equipment to operate. There are other
problems OnStar®cannot control that may prevent
OnStar®from providing OnStar®service to you
at any particular time or place. Some examples are
damage to important parts of your vehicle in an
accident, hills, tall buildings, tunnels, weather
or wireless phone network congestion.
Your Responsibility
You may need to increase the volume of your radio
to hear the OnStar®advisor. If the light next to the

System. If there is one triangular Light Emitting
Diode (LED) above the Universal Home Remote
buttons, follow the instructions below. If your
vehicle has three round LED above the Universal
Home Remote buttons, follow the instructions under
Universal Home Remote System Operation (with
three round LED).
Do not use the Universal Home Remote with any
garage door opener that does not have the stop
and reverse feature. This includes any garage door
opener model manufactured before April 1, 1982.If you have a newer garage door opener with rolling
codes, please be sure to follow Steps 6 through 8 to
complete the programming of your Universal Home
Remote Transmitter.
Read the instructions completely before attempting
to program the Universal Home Remote. Because
of the steps involved, it may be helpful to have
another person available to assist you in the
programming steps.
Keep the original hand-held transmitter for use in
other vehicles as well as for future Universal Home
Remote programming. It is also recommended that
upon the sale of the vehicle, the programmed
Universal Home Remote buttons should be erased
for security purposes. See “Erasing Universal
Home Remote Buttons” later in this section or, for
assistance, seeCustomer Assistance Offices on
page 464.
Be sure that people and objects are clear of the
garage door or gate operator you are programming.
When programming a garage door, it is advised to
park outside of the garage.
It is recommended that a new battery be installed in
your hand-held transmitter for quicker and more
accurate transmission of the radio-frequency signal.

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.

If, after several seconds, all status indicator lights
remain on, or if there are no lights at all, there
may be a problem with the lights or the passenger
sensing system. See your dealer for service.
{CAUTION:
If the off indicator and the airbag readiness
light ever come on together, it means that
something may be wrong with the airbag
system. If this ever happens, have the
vehicle serviced promptly, because an
adult-size person sitting in the right front
passenger seat may not have the
protection of the airbags. SeeAirbag
Readiness Light on page 197.
Charging System Light
When you turn the key to
RUN or START, this light
will come on briey to
show that it is working.
If this light stays on, your vehicle needs service.
You should take your vehicle to the dealer at once.
To save your battery until you get there, turn off
all accessories.
