Buick LaCrosse - 2007 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.
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 450
. 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 484
for more
information.

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 397
and
Taillamps, Turn
Signal, Sidemarker, Stoplamps and Back-up
Lamps on page 398
for turn signal bulb
replacement procedures. Also see

Accessory Power Outlet(s)
The accessory power outlets enable power
electrical equipment such as a cellular telephone
or a CB radio to be used inside the vehicle.
Your vehicle has 12-volt outlets. One outlet is
located on the center console below the climate
controls. There may be another outlet located
inside the center storage console or in the flip and
fold console.
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.
Do not use equipment exceeding maximum
amperage rating of 20 amperes. 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 plugged
in for an extended period of time while the
vehicle is off will drain the battery. Power is
always supplied to the outlets. Always unplug
electrical equipment when not in use and
do not plug in equipment that exceeds
the maximum 20 ampere rating.
When adding electrical equipment, be sure to
follow the proper installation instructions included
with the equipment.
167
Ashtray(s) and Cigarette Lighter
Your vehicle may have a removable ashtray and
cigarette lighter. The cigarette lighter may be
located under the climate control system.
The removable ashtray can be placed into the
front console cupholder.
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 cigarette lighter, push it in all the way,
and let go. When the heating element is 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.
Do not use equipment exceeding maximum
amperage rating of 20 amperes.
Climate Controls
Climate Control System
With this system you can control the heating,
cooling and ventilation for your vehicle.
If your vehicle has the remote start feature and
it is activated, the climate control system will
automatically cool the vehicle if the temperature is
greater than 90°F (32°C) and heat the vehicle if the
temperature is below 37°F (3°C). If the temperature
is between 37°F (3°C) and 90°F (32°C), the last
control setting selected when the engine was
running will be used. Normal operation and the last
setting of the climate control system will return after
the key is turned to the RUN position.
168
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 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 350
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.
353
Notice:
If you leave your radio or other
accessories on during the jump starting
procedure, they could be damaged. The repairs
would not be covered by your warranty.
Always turn off your radio and other
accessories when jump starting your vehicle.
3. Turn off the ignition on both vehicles.
Unplug unnecessary accessories plugged into
the cigarette lighter or the accessory power
outlets. Turn off the radio and all lamps
that are not needed. This will avoid sparks
and help save both batteries. And it could
save the radio!
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 350
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.

To disconnect the jumper cables from both
vehicles, do the following:
1. Disconnect the black negative (
) cable from
the vehicle that had the dead battery.
2. Disconnect the black negative (
) cable from
the vehicle with the good battery.
3. Disconnect the red positive (+) cable from the
vehicle with the good battery.
4. Disconnect the red positive (+) cable from the
other vehicle.
5. Return the fuse block cover to its original
position.
Headlamp Aiming
The vehicle has a visual optical headlamp aiming
system. The aim has been preset at the factory
and should need no further adjustment
However, If the vehicle is damaged in an accident,
the headlamp aim may be affected and adjustment
may be necessary.
If oncoming vehicles flash their high beams at
you, this may also mean the vertical aim needs to
be adjusted.
It is recommended that the vehicle is taken to your
dealer for service if the headlamps need to be
re-aimed. It is possible however, to re-aim
the headlamps as described in the following
procedure.
The vehicle should be properly prepared as follows:
The vehicle should be placed so the headlamps
are 25 ft. (7.6 m) from a light colored wall.
The vehicle must have all four tires on a
perfectly level surface which is level all the way
to the wall.
The vehicle should be placed so it is
perpendicular to the wall.
The vehicle should not have any snow, ice or
mud on it.
The vehicle should be fully assembled and all
other work stopped while headlamp aiming is
being done.
The vehicle should be normally loaded with a
full tank of fuel and one person or 160 lbs
(75 kg) on the driver’s seat.
Tires should be properly inflated.
391
Electrical System
Add-On Electrical Equipment
Notice:
Do not add anything electrical to your
vehicle unless you check with your dealer
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 80
.
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.
449
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.
Instrument Panel Fuse Block
The instrument panel
fuse block is located on
the passenger’s side
of the instrument panel.
Pull off the cover
labeled FUSES to
expose the fuse block.
