2003 BUICK LESABRE fuses

Testing the Alarm
The alarm can be tested by following these steps:
1. From inside the vehicle, roll down the driver's
window and open the driver's door.
2. Activate the system by locking the doors with the
power door lock switch while the door is open, or
with the remote keyless entry transmitter.
3. Get out of the car, close the door and wait for the
SECURITY light to go out.
4. Then reach in through the window, unlock the door
with the manual door lock and open the door. This
should set off the alarm.
If the alarm does not sound when it should, but the
vehicle's lamps ¯ash, check to see if the horn works.
The horn fuse may be blown. To replace the fuse,
see
Fuses and Circuit Breakers on page 5-86.
If the alarm does not sound or the vehicle's lamps do
not ¯ash, the vehicle should be serviced by an
authorized service center.

2-19

PASS-KeyžIII Operation
Your vehicle is equipped
with the PASS-KeyžIII
(Personalized Automotive
Security System)
theft-deterrent system.
PASS-Key
žIII is a passive
theft-deterrent system.
This means you don't have
to do anything different
to arm or disarm the
system. It works when you
insert or remove the key
from the ignition.
When the PASS-Key
žIII system senses that someone
is using the wrong key, it shuts down the vehicle's
starter and fuel systems. The starter will not work and
fuel will stop being delivered to the engine. 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 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 5-86. If the engine still
does not start with the other key, your vehicle needs
service. If your vehicle does start, the ®rst key may be
faulty. See your dealer who can service the
PASS-Key
žIII to have a new key made.
It is possible for the PASS-KeyžIII decoder to learn the
transponder value of a new or replacement key. Up
to 10 additional keys may be programmed for the
vehicle. This procedure is for programming additional
keys only.
Canadian Owners:If you lose or damage your keys,
only a GM dealer can service PASS-Key
žIII to
have new keys made. To program additional keys you
will need two current driver's keys. You must add a step
to the following procedure. After Step 2, repeat
Steps 1 and 2 with the second current driver's key. Then
continue with Step 3.
To program the new key, do the following:
1. Verify that the new key has PK3
žstamped on it.
2. Insert the current driver's key in the ignition
and start the engine. If the engine will not start, see
your dealer for service.
3. After the engine has started, turn the key to OFF,
and remove the key.

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 ¯ash in
the direction of the
turn or lane change.
If your vehicle is equipped with the Head-Up Display
(HUD), an arrow will also appear in the display area to
indicate the direction of the turn or lane change.
See
Head-Up Display (HUD) on page 3-20for more
information.
You may also have an arrow in the outside mirror that
¯ashes when the turn signal is used. See
Outside Power
Mirrors on page 2-35for more information.
Raise or lower the lever until the arrow starts to ¯ash to
signal a lane change. Hold it there until the lane
change is complete.
If the arrows ¯ash very fast as you signal a turn or a
lane change, a signal bulb may be burned out and other
drivers won't see your turn signal.If a bulb is burned out, replace it to help avoid an
accident. If the arrows don't go on at all when you signal
a turn, check the fuse. See
Fuses and Circuit Breakers
on page 5-86.
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 ¯ash 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
or high beam to low beam, pull the turn signal lever
toward you and release it.
When the high beams are
on, this light located on the
instrument panel cluster
will also be on.
If your vehicle is equipped with the Head-Up Display
(HUD), this symbol will also appear in the display area to
indicate the high beams are on. See
Head-Up Display
(HUD) on page 3-20for more information.

3. Now press the image height adjuster switch to
position the image as low as possible, while still
keeping it in full view.
4. Slide the dimmer lever downward until the HUD
image is no brighter than necessary.
To turn the HUD display off, slide the dimmer lever all
the way down.
If the sun comes out and the sky becomes cloudy, you
may need to adjust the HUD brightness using the
dimmer lever. Polarized sunglasses could make the
HUD image harder to see.
To change the display from English to metric units, push
the ENG/MET button located to the left of the steering
column.
Clean the inside of the windshield as necessary to
remove any dirt or ®lm that reduces the sharpness or
clarity of the HUD image.
To clean the HUD lens, spray household glass cleaner
on a soft, clean cloth. Gently wipe and dry the HUD
lens. Do not spray cleaner directly on the lens to avoid
cleaner leaking inside the unit.
If the ignition is on and you can't see the HUD image,
check to see if:
·Something is covering the HUD unit.
·The HUD dimmer lever is adjusted properly.
·The HUD image is adjusted to the proper height.
·A fuse is blown. SeeFuses and Circuit Breakers on
page 5-86
.Keep in mind that your windshield is part of the HUD
system. If you ever have your windshield replaced,
be sure to get one that is designed for HUD or your HUD
image may look blurred or out of focus.
Accessory Power Outlets
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 ®nd 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.
The accessory power outlets will only operate when the
ignition key is in RUN and for 10 minutes after turning
the ignition off. If you would like the outlets to operate
regardless of ignition position, and for extended periods
of time, see ªEngine Compartment Fuse Blockº under
Fuses and Circuit Breakers on page 5-86or contact
your dealer.
3-22

Notice:When using an accessory power outlet,
maximum electrical load must not exceed 15 amps.
Always turn off any electrical equipment when
not in use. Leaving electrical equipment on for
extended periods will drain your battery.
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 some electrical equipment to your
vehicle can damage it or keep other things from
working as they should. This wouldn't be covered by
your warranty. Check with your dealer before
adding electrical equipment, and never use anything
that exceeds the amperage rating.
When adding electrical equipment, be sure to follow the
proper installation instructions included with the
equipment.
Notice:Power outlets are designed for accessory
plugs only. Do not hang any type of accessory
or accessory bracket from the plug. Improper use of
the power outlet can cause damage not covered
by your warranty.
Ashtrays and Cigarette Lighter
Pull down the front center tray to reveal the front
ashtray, cigarette lighter and accessory power outlet.
The front center and rear ashtrays may be removed for
cleaning. Hold the sides of the ashtray and then pull
the ashtray up and out.
Notice:Don't put papers or other ¯ammable
items into your ashtrays. Hot cigarettes or other
smoking materials could ignite them, causing
a damaging ®re.
To use a 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:Don't hold a cigarette lighter in with your
hand while it is heating. If you do, it won't be able to
back away from the heating element when it's
ready. That can make it overheat, damaging the
lighter and the heating element.
The cigarette lighter will only operate when the ignition
key is in RUN and for 10 minutes after turning the
ignition off. If you would like the lighter to operate
regardless of ignition position, and for extended periods
of time, see ªEngine Compartment Fuse Blockº under
Fuses and Circuit Breakers on page 5-86or see
your dealer.

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 ®xed
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 ®res
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 ®nd 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.
Engine Compartment Fuse Block
The engine compartment
fuse block is located near
the front on the
passenger's side of the
vehicle. See
Engine
Compartment Overview on
page 5-12
for more
information on location.
Lift the cover to gain access. On some vehicles, there
may be an additional cover that you will need to lift
to gain access to the fuses.
Fuse 22 or 23 can be moved to the outer position to
provide continuous power to the auxiliary outlets
or cigarette lighter when the ignition is not on. See your
dealer for additional assistance, if needed.
