Buick LeSabre - 2005 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 the 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 different 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 shuts down the vehicle’s
starter and fuel systems. The starter will not work and
fuel will stop being delivered to the engine. 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 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 undamaged, try another ignition key. At this time,
you may also want to check the fuse. See
Fuses
and Circuit Breakers on page 5-88
. 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.
It is possible for the PASS-Key
®
III decoder to learn the
transponder value of a new or replacement key. Up
to 10 additional keys may be programmed for the
vehicle. This procedure is for programming additional
keys only.
Canadian Owners:
If you lose or damage your keys,
only a GM dealer can service PASS-Key
®
III to
have new keys made. To program additional keys you
will need two current driver’s keys. You must add a step
to the following procedure. After Step 2, repeat
Steps 1 and 2 with the second current driver’s key. Then
continue with Step 3.
2-20
You may also have an arrow in the outside mirror that
flashes when the turn signal is used. See
Outside Power
Mirrors on page 2-35
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 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 5-88
.
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 flash 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. See
Head-Up Display
(HUD) on page 3-20
for 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 briefly to
flash-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.

2. Adjust the seat to your driving position. Press the
image height adjuster switch to raise the image as
far as possible.
3. Now press the image height adjuster switch to
position the image as low as possible, while still
keeping it in full view.
4. Slide the dimmer lever downward until the HUD
image is no brighter than necessary.
To turn the HUD display off, slide the dimmer lever
to OFF.
If the sun comes out and the sky becomes cloudy, you
may need to adjust the HUD brightness using the
dimmer lever. Polarized sunglasses could make the
HUD image harder to see.
To change the display from English to metric units,
push the ENG/MET button located to the left of
the steering column.
Clean the inside of the windshield as necessary to
remove any dirt or film that reduces the sharpness or
clarity of the HUD image.
To clean the HUD lens, spray household glass cleaner
on a soft, clean cloth. Gently wipe and dry the HUD
lens. Do not spray cleaner directly on the lens to avoid
cleaner leaking inside the unit.
If the ignition is in RUN and you cannot see the HUD
image, check to see if:
Something is covering the HUD unit.
The HUD dimmer lever is adjusted properly.
The HUD image is adjusted to the proper height.
A fuse is blown. See
Fuses and Circuit Breakers on
page 5-88
.
Keep in mind that your windshield is part of the HUD
system. If you ever have your windshield replaced,
be sure to get one that is designed for HUD or your HUD
image may look blurred or out of focus.
Accessory Power Outlets
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 find two outlets inside the rear storage compartment.
An extra power outlet can be found in the ashtray.
3-22
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. 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.
Ashtrays and Cigarette Lighter
Pull down the front center tray to reveal the front
ashtray, cigarette lighter and accessory power outlet.
The front center and rear ashtrays can be removed for
cleaning. Hold the sides of the ashtray and then pull
the ashtray up and out.
Notice:
If you put papers 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. Do not
use anything other than the cigarette lighter in the
heating element.

Engine Oil
If the ENGINE OIL LOW
CHECK LEVEL DIC
message appears on the
instrument cluster, it
means you need to check
your engine oil level
right away. For more
information, see
DIC
Warnings and Messages
on page 3-50
.
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.

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 5-91
. You do not need to access the battery to
jump start your vehicle. See
Jump Starting on
page 5-40
.
{
CAUTION:
A battery that is not properly vented can let
sulfuric acid fumes into the area under the rear
seat cushion. These fumes can damage your
rear seat safety belt systems. You may not be
able to see this damage, and the safety belts
might not provide the protection needed in a
crash. If a replacement battery is ever needed,
it must be vented in the same manner as the
original battery. Always make sure that the
vent hose is properly reattached before
reinstalling the seat cushion.
5-38
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 1-56
.
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.
5-88
Engine Compartment Fuse Block
The engine compartment
fuse block is located near
the front on the
passenger’s side of the
vehicle. See
Engine
Compartment Overview on
page 5-12
for more
information on location.
Lift the cover to gain access. On some vehicles, there
may be an additional cover that you will need to lift
to gain access to the fuses.

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 reinstall the rear seat cushion, do the following:
{
CAUTION:
A safety belt that is not properly routed
through the seat cushion or is twisted will not
provide the protection needed in a crash. If the
safety belt has not been routed through the
seat cushion at all, it will not be there to work
for the next passenger. The person sitting in
that position could be badly injured. After
reinstalling the seat cushion, always check to
be sure that the safety belts are properly
routed and are not twisted.
