Buick LaCrosse - 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 nothing special
needs to be done to arm
or disarm the system.
It works when the key
is inserted or removed
from the ignition.
PASS-Key III
®
uses a transponder in the ignition key
that matches a decoder in the vehicle.
When the PASS-Key
®
III system senses that the wrong
key has been inserted into the ignition, it shuts down
the vehicle’s starter and fuel systems. The starter will
not work and fuel will stop flowing to the engine.
If someone tries to start the vehicle again with the
wrong key, the vehicle will not start. Anyone using
a trial-and-error method to start the vehicle will
be discouraged to do so because of the high number
of electrical key codes.
When trying to start the vehicle, if the engine does not
start and the STARTING DISABLED warning message
on the Driver Information Center (DIC) 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 5-93
. If the engine still
does not start with the other key, the vehicle needs
service. If the 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
for
more information.
It is possible for the PASS-Key
®
III decoder to accept
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 programmed keys are lost or do
not operate, see your dealer or a locksmith who
can service PASS-Key
®
III to have keys made and
programmed to the system.
2-21
Turn and Lane-Change Signals
To signal a turn, move the lever up or down. The lever
returns to its original position when the turn is completed.
An arrow on the instrument
panel cluster will flash in
the direction of the
turn or lane change.
To signal a lane change, raise or lower the lever until the
arrow starts to flash. Hold it there until the lane change is
completed. The lever will return to its original position
when released.
Arrows that flash rapidly when signaling for a turn or lane
change, or that fail to work, may indicate a burned-out
signal bulb or fuse. Other drivers will not see the signal.
See
Front Turn Signal and Parking Lamps on page 5-53
and
Taillamps, Turn Signal, Sidemarker, Stoplamps and
Back-up Lamps on page 5-54
for turn signal bulb
replacement procedures. Also see
Fuses and Circuit
Breakers on page 5-93
for location of fuses.
A chime will sound if the turn signal is left on for more
than 3/4 mile (1.2 km).
Headlamp High/Low-Beam Changer
To change the headlamps from low beam to high beam,
push the turn signal/multifunction lever away from you.
When the high beams are
on, a light on the instrument
panel cluster also will be on
if the ignition is on.
To change the headlamps from high beam to low beam,
pull the turn signal lever toward you.
Flash-to-Pass
This feature lets you use your high-beam headlamps
momentarily to signal a driver in front of you that
you want to pass.
To use it, pull the turn signal/multifunction lever toward
you until the high-beam headlamps come on, then
release the lever to turn them off.
3-8
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.
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.
When adding electrical equipment, be sure to follow
the proper installation instructions included with
the equipment.
Ashtray(s) and Cigarette Lighter
You may have an ashtray and cigarette lighter.
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 remove the ashtray, pull it from the center console.
Slide it back in and push down to be sure it is secure.
To use the cigarette lighter, push it in all the way, and let
go. When it’s ready, it will pop back out by itself.
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.
3-21
Oil Pressure Light
Your vehicle may have this
feature. If the vehicle has
an oil problem, this light
may stay on after the
engine is started, or come
on while you are driving.
This light indicates that oil is not going through the
engine quickly enough to keep it lubricated. The engine
could be low on oil or could have some other oil
problem. Have it fixed right away.
The oil light could also come on in the following
situations:
The light will come on briefly when the ignition
is turned on to show that it is working properly.
If it does not come on with the ignition on,
there may be a problem with the fuse or bulb.
Have it fixed right away.
Sometimes when the engine is idling at a stop,
a chime will sound and the light may blink on
and off. This is normal.
{
CAUTION:
Do not keep driving if the oil pressure is low.
If you do, your engine can become so hot that
it catches fire. You or others could be burned.
Check your oil as soon as possible and have
your vehicle serviced.
Notice:
Lack of proper engine oil maintenance
may damage the engine. The repairs would not
be covered by your warranty. Always follow
the maintenance schedule in this manual for
changing engine oil.

Engine Oil
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
4. Open the hood on the other vehicle and locate the
positive (+) and negative (
) terminal locations on
that vehicle.
You will not use your vehicle’s battery for jump
starting. It has a remote positive (+) jump starting
terminal, located on the underhood fuse block, for
that purpose. See
Engine Compartment Overview on
page 5-12
for more information on location.
To uncover the remote
positive (+) terminal, press
the tab at the bottom of
the fuse block and lift
the cover up.
Always use the remote positive (+) terminal instead
of the positive (+) terminal on the battery.
{
CAUTION:
An electric fan can start up even when the
engine is not running and can injure you.
Keep hands, clothing and tools away from any
underhood electric fan.
{
CAUTION:
Fans or other moving engine parts can injure
you badly. Keep your hands away from moving
parts once the engine is running.

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 1-65
.
Headlamp Wiring
The headlamp wiring is protected by a circuit breaker
in the underhood fuse block. An electrical overload
will cause the headlamps to go on and off, or in some
cases to remain off. If this happens, have the headlamp
system checked right away.
Windshield Wiper Fuses
The windshield wiper motor is protected by a circuit
breaker and a fuse. If the motor overheats due to heavy
snow, etc., the wiper will stop until the motor cools.
If the overload is caused by some electrical problem,
have it fixed.
Power Windows and Other
Power Options
Circuit breakers in the instrument panel 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.
Fuses and Circuit Breakers
The wiring circuits in the vehicle are protected from
short circuits by a combination of fuses, circuit breakers
and in the fuse block wiring itself. 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. Make sure
a bad fuse is replaced with a new one of the identical
size and rating.
