Buick Lucerne - 2007 Fuse Box Diagram

Buick Lucerne - 2007 Fuse Box Diagram

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 428
.
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, push the turn signal lever away from
you. To change from high beam to low beam,
pull the turn signal lever toward you.
While the high beams
are on, this light located
on the instrument
panel cluster will
also be on.

For Driver Information Center messages related to
URPA, see
DIC Warnings and Messages on
page 221
.
If the bumper is damaged, your URPA system
may not work properly. Take the vehicle to
your dealer to repair the system.
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 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.
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.
Do not use equipment exceeding maximum
amperage rating of 20 amperes. 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.

Ashtray(s) and Cigarette Lighter
Push down on the front center tray to reveal the
front ashtray, cigarette lighter, and accessory
power outlet. The ashtray can be removed
for cleaning. Hold the sides of the ashtray
and then pull the ashtray up and out.
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 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.
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 heat and
cool the inside of the vehicle, using the previous
system settings before the vehicle was turned off.
The rear window defogger will be turned on by the
climate control system when it is cold outside. If the
vehicle has heated seats, they will also turn on.
Cooled seats are not activated during a remote
start. Normal operation of the system will return
after the key is turned to the RUN position. See
Remote Keyless Entry (RKE) System Operation on
page 95
for more information.

Engine Oil
If the OIL LEVEL LOW ADD OIL message
appears in the Driver Information Center (DIC), it
means you need to check the engine oil level
right away. For more information, see
DIC
Warnings and Messages on page 221
. You should
check the engine oil level regularly; this is an
added reminder.
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 334
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 431
. You do not need to access
the battery to jump start your vehicle. See
Jump Starting on page 372
.

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 86
.
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.
Underhood Fuse Block
The underhood fuse block is located on the
passenger’s side of the engine compartment.
Remove the fuse cover and secondary service
cover to access the fuse block.

Rear Underseat Fuse Block
The rear fuse block is located under the rear seat
on the driver’s side. The rear seat cushion
must be removed to access the rear fuse block.
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.
3. To access the fuse block, pull out and lift up
on the cover latch, located at the end of the
