Buick Century - 2004 Fuse Box Diagram

The ignition key must be clean and dry before it is
inserted in the ignition or the engine may not start. If the
engine does not start and the SECURITY warning
light on the instrument panel is flashing, the key may be
dirty or wet. Turn the ignition off.
Clean and dry the key. Wait about three minutes and try
again. If the vehicle still does not start, the ignition
key may be faulty. Wait about three more minutes and
try a spare ignition key. At this time, you may also
want to check the fuse. See
Fuses and Circuit Breakers
on page 5-97
for information on fuse location. If the
starter will not work with the spare key, the vehicle
needs service. See your dealer or a locksmith who can
service the PASS-Key
®
II.
If a key is accidentally used that has a damaged or
missing resistor pellet, the starter will not work.
The SECURITY warning light on the instrument panel
will then come on. But you do not have to wait three
minutes before trying another ignition key.
See your dealer or a locksmith who can service the
PASS-Key
®
II to have a new key made.
If the SECURITY warning light comes on the instrument
panel while the vehicle is being driven, the engine
will still be able to be started after it is turned off. The
PASS-Key
®
II system, however, is not working properly
and must be serviced by your dealer. The vehicle is
not protected by the PASS-Key
®
II system when
this happens.
If a PASS-Key
®
II ignition key is lost or damaged,
see your dealer or a locksmith who can service
PASS-Key
®
II to have a new key made. Also, see
Roadside Assistance Program on page 7-5
for more
information.
Starting and Operating Your
Vehicle
New Vehicle Break-In
Notice:
Your vehicle does not need an elaborate
“break-in.” But it will perform better in the long run
if you follow these guidelines:
Do not drive at any one speed — fast or
slow — for the first 500 miles (805 km). Do not
make full-throttle starts.
Avoid making hard stops for the first 200 miles
(322 km) or so. During this time your new
brake linings are not yet broken in. Hard stops
with new linings can mean premature wear
and earlier replacement. Follow this breaking-in
guideline every time you get new brake
linings.
Do not tow a trailer during break-in. See
Towing
a Trailer on page 4-39
for more information.

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 5-52
and
Taillamps, Turn Signal, and
Stoplamps on page 5-54
for turn signal bulb replacement
procedures. Also see
Fuses and Circuit Breakers on
page 5-97
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 beams to high
beams, or high to low, pull the multifunction lever until a
click is heard, then release it.
This indicator light on
the instrument panel
cluster will come on
while the high-beam
lamps are on.
Flash-to-Pass
This feature lets you use your high-beam headlamps to
signal the driver in front of you that you want to pass.
It works even if the headlamps are off. Pull the turn
signal lever toward you a little, but not so much that you
hear a click.
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. The high-beam indicator
on the instrument panel cluster will come on.
3-6
Accessory Power Outlets
The accessory power outlets enable power electrical
equipment such as a cellular telephone or a CB radio
to be used inside the vehicle.
The vehicle is equipped with a 12-volt outlet. It is
located on the console, near the floor on the
passenger’s side. Open the cover to use the outlet. Be
sure to close the cover when the outlet is not in use.
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.
Certain power accessory plugs may not be compatible
to the power accessory outlet and could result in
blown vehicle or adapter fuses. If you experience a
problem, see your dealer.
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.
Ashtrays and Cigarette Lighter
The center front ashtray is located below the instrument
panel comfort controls.
To remove the ashtray, open the storage door. Then
open the ashtray lid, lift up and pull it out.
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.
Push the lighter to use it. When the heating element is
hot, the lighter will pop back out by itself.
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.
3-17
Oil Pressure Light
If the vehicle has a 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, 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.
Turn off the engine and give the oil several minutes to
drain back into the oil pan. If you don’t, the oil
dipstick might not show the actual level.
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.
5-13
The system normally takes 15 to 20 minutes of driving
time in each of three speed ranges to determine
tire pressures. The speed ranges are 15 to 40 mph
(25 to 65 km/h), 40 to 65 mph (65 to 105 km/h)
and above 65 mph (105 km/h). When the storage of the
tire inflation information is complete, the LOW TIRE
light will come on the instrument panel after two
to eight minutes if one tire is inflated 12 psi (83 kPa)
less than the other three tires. Detection thresholds
may be higher and detection times may be longer on
rough roads, curves and at high speeds. The system is
not capable of inflation differences at speeds greater
than 70 mph (110 km/h).
The tire inflation monitor system will not alert you if the
pressure in more than one tire is low, if the system
is not properly calibrated, or if the vehicle is moving
faster than 70 mph (110 km/h).
The LOW TIRE light will stay on while the ignition is on,
until the system is reset
Do not reset the tire inflation monitor system without
first correcting the cause of the problem and checking
and adjusting the pressure in all four tires. If the
system is reset when the tire pressures are incorrect, it
will not function properly and may not alert you when
a tire is low.
Any time a tire’s pressure is adjusted, the tires are
rotated, or one or more tires is repaired or replaced, the
tire inflation monitor system will need to be reset. The
system also needs to be reset when new tires are
purchased and if the vehicle’s battery has been
disconnected.
To reset the system:
1. Turn the ignition to RUN.
2. Remove the passenger’s side instrument panel
cover to get to the fuse block.
3. Press and hold the RESET button in the fuse block
for about five seconds.
4. The LOW TIRE light will come on and flash
three times. Then it will go off. If the light does
not go off, see your dealer for service.

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.
The vehicle has an air bag system. Before attempting to
add anything electrical to the vehicle, see
Servicing
Your Air Bag-Equipped Vehicle on page 1-58
.
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. Be sure
a bad fuse is replaced with a new one of the identical
size and rating.
5-97
Instrument Panel Fuse Block
Some fuses are located in
a fuse block on the
passenger’s side of the
instrument panel. Pull off
the cover labeled
FUSES to expose the
fuse block.
