Buick Lucerne - 2006 Fuse Box Diagram

These are some examples of symbols that may be found on the vehicle:
v
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, see
Fuses
and Circuit Breakers on page 5-93
. If the engine
still does not start with the other key, your vehicle needs
service. If your vehicle does start, the first 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. See
Roadside
Assistance Program on page 7-6
.
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.

Turn and Lane-Change Signals
To signal a turn, move the lever on the left side of the
steering wheel all the way up or down. The lever returns
automatically when the turn is complete.
An arrow on the instrument
panel cluster will flash in
the direction of the
turn or lane change.
You may also have an arrow in the outside mirror that
flashes when the turn signal is used. See
Outside Power
Mirrors on page 2-36
for more information.
Raise or lower the lever until the arrow starts to flash 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 flash three times.
If the arrows flash 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. See
Fuses and Circuit Breakers on
page 5-93
.

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. 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.
Ashtray(s) and Cigarette Lighter
Push down on the front center tray to reveal the front
ashtray, cigarette lighter, and accessory power outlet.
The ashtray can be removed for cleaning. Hold the sides
of the ashtray and then pull the ashtray up and out.
Notice:
If you put papers, pins, or other flammable
items in the ashtray, hot cigarettes or other
smoking materials could ignite them and possibly
damage your vehicle. Never put flammable items in
the ashtray.
To use the lighter, push the center all the way in and
let it go. When it is ready, the center will pop back
out by itself. Pull out the entire unit to use it.
Notice:
Holding a cigarette lighter in while it is
heating will not allow the lighter to back away from
the heating element when it is hot. Damage from
overheating may occur to the lighter or heating
element, or a fuse could be blown. Do not hold a
cigarette lighter in while it is heating.

Engine Oil
If the ENGINE OIL LOW ADD OIL message appears in
the Driver Information Center (DIC), it means you
need to check your engine oil level right away. For more
information, see
DIC Warnings and Messages on
page 3-56
.
You should check your engine oil level regularly; this is
an added reminder.
Checking Engine Oil
It is a good idea to check your engine oil every time you
get fuel. In order to get an accurate reading, the oil
must be warm and the vehicle must be on level ground.
The engine oil dipstick handle is a yellow loop. See
Engine Compartment Overview on page 5-12
for
the location of the engine oil dipstick.
1. Turn off the engine and give the oil several minutes
to drain back into the oil pan. If you do not do this,
the oil dipstick might not show the actual level.
2. Pull out the dipstick and clean it with a paper towel
or cloth, then push it back in all the way. Remove it
again, keeping the tip down, and check the level.
5-15
Brake Pedal Travel
See your dealer if the brake pedal does not return to
normal height, or if there is a rapid increase in
pedal travel. This could be a sign of brake trouble.
Brake Adjustment
Every time you apply the brakes, with or without the
vehicle moving, your brakes adjust for wear.
Replacing Brake System Parts
The braking system on a vehicle is complex. Its many
parts have to be of top quality and work well together if
the vehicle is to have really good braking. Your
vehicle was designed and tested with top-quality GM
brake parts. When you replace parts of your braking
system — for example, when your brake linings
wear down and you need new ones put in — be sure
you get new approved GM replacement parts. If you do
not, your brakes may no longer work properly. For
example, if someone puts in brake linings that are wrong
for your vehicle, the balance between your front and
rear brakes can change — for the worse. The braking
performance you have come to expect can change
in many other ways if someone puts in the wrong
replacement brake parts.
Battery
Your vehicle has a maintenance free battery. When it is
time for a new battery, get one that has the replacement
number shown on the original battery’s label. We
recommend an ACDelco
®
replacement battery.
Warning:
Battery posts, terminals, and related
accessories contain lead and lead compounds,
chemicals known to the State of California to cause
cancer and reproductive harm. Wash hands after
handling.
The battery is located under the rear seat cushion. To
access the battery, see “Removing the Rear Seat
Cushion” under
Rear Underseat Fuse Block on
page 5-96
. You do not need to access the battery to
jump start your vehicle. See
Jump Starting on
page 5-44
.
5-42
Electrical System
Add-On Electrical Equipment
Notice:
Don’t add anything electrical to your
vehicle unless you check with your dealer first.
Some electrical equipment can damage your vehicle
and the damage wouldn’t be covered by your
warranty. Some add-on electrical equipment can
keep other components from working as they
should.
Your vehicle has an airbag system. Before attempting to
add anything electrical to your vehicle, see
Servicing
Your Airbag-Equipped Vehicle on page 1-67
.
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 fixed
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 fires
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 find 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.
5-93
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.

Rear Underseat Fuse Block
The rear fuse block is located under the rear seat on
the driver’s side. The rear seat cushion must be
removed to access the rear fuse block.
Removing the Rear Seat Cushion
Notice:
If you touch the exposed wires with the
metal on the seat cushion, you could cause a short
that could damage the battery and or wires. Avoid
contact between the rear seat and the fuse
center whenever you remove or reinstall the rear
seat. Do not remove covers from any of the covered
parts, and do not store anything under the seats.
To remove the rear seat cushion, do the following:
1. Pull up on the front of the cushion to release the
front hooks.
2. Pull the cushion up and out toward the front of the
vehicle.
To access the fuse block, pull out and lift up on the
cover latch, located at the end of the fuse block, near
the battery cable.
