2007 BUICK LUCERNE fuses

PASS-Key®III+ Operation
Your vehicle is equipped with PASS-Key®III+
(Personalized Automotive Security System)
theft-deterrent system. PASS-Key
®III+ is a
passive theft-deterrent system. This means you do
not have to do anything special to arm or disarm
the system. It works when you insert or remove the
key from the ignition.
When the PASS-Key
®III+ system senses that
someone is using the wrong key, it prevents the
vehicle from starting. Anyone using a trial-and-error
method to start the vehicle will be discouraged
because of the high number of electrical key codes.
When trying to start the vehicle if the engine does
not start and the security light on the instrument
panel cluster comes on, the key may have a
damaged transponder. Turn the ignition off and
try again.If the engine still does not start, and the key
appears to be not damaged, try another ignition
key. At this time, you may also want to check the
fuse, seeFuses and Circuit Breakers on page 428.
If the engine still does not start with the other key,
your vehicle needs service. If your vehicle does
start, the rst key may be faulty. See your dealer
who can service the PASS-Key
®III+ to have a new
key made. In an emergency, contact Roadside
Assistance. SeeRoadside Assistance Program
on page 466.
It is possible for the PASS-Key
®III+ decoder
to “learn” the transponder value of a new or
replacement key. Up to 10 keys may be
programmed for the vehicle. The following
procedure is for programming additional keys
only. If all the currently programmed keys are lost
or do not operate, you must see your dealer or a
locksmith who can service PASS-Key
®III+ to have
keys made and programmed to the system.
See your dealer or a locksmith who can service
PASS-Key
®III+ to get a new key blank that is cut
exactly as the ignition key that operates the system.

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 you momentarily press
and release the lever, the turn signal will ash
three times.
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 428.
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, push the turn signal lever away from
you. To change from high beam to low beam,
pull the turn signal lever toward you.
While the high beams
are on, this light located
on the instrument
panel cluster will
also be on.

For Driver Information Center messages related to
URPA, seeDIC Warnings and Messages on
page 221.
If the bumper is damaged, your URPA system
may not work properly. Take the vehicle to
your dealer to repair the system.
Accessory Power Outlet(s)
The accessory power outlets can be used to plug in
electrical equipment such as a cellular telephone or
CB radio.
Your vehicle may have up to three power outlets
depending on the type of front seat you have.
If your vehicle has front bucket seats with a center
console, you will nd two outlets inside the rear
storage compartment. An extra power outlet
can be found in the ashtray.
Your vehicle may have a small cap that must be
pulled down to access the accessory power outlet.
If it does, when not using the outlet be sure to
cover it with the protective cap.
Notice:Leaving electrical equipment on for
extended periods will drain the battery. Always
turn off electrical equipment when not in use
and do not plug in equipment that exceeds the
maximum amperage rating.Certain electrical accessories may not be
compatible to the accessory power outlets and
could result in blown vehicle or adapter fuses. If
you experience a problem see your dealer for
additional information on the accessory power
outlets.
Notice:Adding any electrical equipment to
your vehicle may damage it or keep other
components from working as they should. The
repairs would not be covered by your warranty.
Do not use equipment exceeding maximum
amperage rating of 20 amperes. Check with
your dealer before adding electrical equipment.
When adding electrical equipment, be sure to
follow the proper installation instructions included
with the equipment.
Notice:Improper use of the power outlet can
cause damage not covered by your warranty.
Do not hang any type of accessory or
accessory bracket from the plug because the
power outlets are designed for accessory
power plugs only.

Electrical System
Add-On Electrical Equipment
Notice:Do not add anything electrical to your
vehicle unless you check with your dealer
rst. Some electrical equipment can damage
your vehicle and the damage would not
be covered by your warranty. Some add-on
electrical equipment can keep other
components from working as they should.
Add-on equipment can drain your vehicle’s battery,
even if your vehicle is not operating.
Your vehicle has an airbag system. Before
attempting to add anything electrical to your
vehicle, seeServicing Your Airbag-Equipped
Vehicle on page 86.
Power Windows and Other Power
Options
Circuit breakers in the rear fuse block protect the
power windows and other power accessories.
When the current load is too heavy, the circuit
breaker opens and closes, protecting the circuit
until the problem is xed or goes away.
Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected
from short circuits by a combination of fuses
and circuit breakers. This greatly reduces
the chance of res caused by electrical problems.
Look at the silver-colored band inside the fuse.
If the band is broken or melted, replace the fuse.
Be sure you replace a bad fuse with a new
one of the identical size and rating.
You will nd a fuse puller clipped in both of the
fuse blocks. Snap the wide end of the fuse puller
at the side indentations and pull the fuse out.
The MaxiFuses are located in two fuse blocks,
one located in the engine compartment on
the passenger’s side and the other under the rear
seat on the driver’s side. If a MaxiFuse should
blow, have your vehicle serviced by your dealer
immediately.
Underhood Fuse Block
The underhood fuse block is located on the
passenger’s side of the engine compartment.
Remove the fuse cover and secondary service
cover to access the fuse block.
