Buick Lucerne - 2008 Fuse Box Diagram

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.
The system is automatically armed when the key is
removed from the ignition.
You do not have to manually arm or disarm the system.
The security light will come on if there is a problem
with arming or disarming the theft-deterrent system.
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, there may be a problem with your
theft-deterrent system. 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 5-105
. 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/retailer 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 7-8
.
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/retailer
or a locksmith who can service PASS-Key
®
III+ to have
keys made and programmed to the system.
See your dealer/retailer 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 2-37
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 5-105
.

Battery Run-Down Protection
This vehicle has a feature to help prevent the battery
from being drained, if the interior courtesy lamps,
reading/map lamps, visor vanity lamps or trunk lamp are
accidentally left on. If any of these lamps are left on,
they will automatically turn off after 10 minutes, if
the ignition is off. The lamps will not come back on again
until one of the following occurs:
The ignition is turned on.
The exterior lamps control is turned off, then on
again.
The headlamps will timeout after 10 minutes, if they are
manually turned on before the ignition is off.
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 installed. If your
vehicle has front bucket seats with a center console,
there are two outlets inside the rear storage
compartment. An extra power outlet can be found under
the climate control system next to the ashtray.
Your vehicle may have a small cap that must be pulled
down to access the accessory power outlet. Cover the
outlet with the protective cap when it is not being used.
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/retailer 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/retailer before adding
electrical equipment.

Engine Oil
Checking Engine Oil
It is a good idea to check the 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
Battery
Your vehicle has a maintenance free battery. When it is
time for a new battery, see your dealer/retailer for
one that has the replacement number shown on the
original battery’s label.
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 5-108
. You do not need to access the battery to
jump start your vehicle. See
Jump Starting on
page 5-48
.
{
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.

Electrical System
Add-On Electrical Equipment
Notice:
Do not add anything electrical to your
vehicle unless you check with your dealer/retailer
first. 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, see
Servicing
Your Airbag-Equipped Vehicle on page 1-72
.
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/retailer immediately.
5-105
Underhood Fuse Block
The underhood fuse block is located on the passenger side of the engine compartment. Remove the fuse cover and
secondary service cover to access the fuse block.
Notice:
Spilling liquid on any electrical components on your vehicle may damage it. Always keep the covers
on any electrical component.
