2003 CADILLAC SEVILLE fuses

Testing the Alarm
1. From inside the vehicle, roll down the window, then
get out of the vehicle, keeping the door open.
2. From outside of the vehicle, with the door open,
lock the vehicle using the power door lock or the
remote keyless entry transmitter and close the
door. Wait 30 seconds until the SECURITY lamp
goes off.
3. Reach in and unlock the door using the manual
lock and open the door. The horn will sound and
the hazard lights will ¯ash.
You can turn off the alarm by unlocking the driver's door
with your key, using the unlock button on the remote
keyless entry transmitter or by starting the car with
a valid key.
If the alarm does not sound when it should, check to
see if the horn works. The horn fuse may be blown. To
replace the fuse, see
Fuses and Circuit Breakers on
page 5-93. If the fuse does not need to be replaced, you
may need to have your vehicle serviced.
To reduce the possibility of theft, always arm the
theft-deterrent system when leaving your vehicle.
Valet Lockout Switch
The valet lockout switch
is located inside the
glove box.
Press the switch to ON to disable the use of the trunk,
fuel door, garage door opener and cellular telephone
(option). The remote keyless entry transmitter cannot
open the trunk if the valet lockout switch is in ON.
Press this switch to OFF to enable the use of the trunk,
fuel door, garage door opener and optional cellular
telephone.
Locking the glove box with your key will also help to
secure your vehicle.

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 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 5-93. 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
ž
III to have a new key made.It is possible for the PASS-Key
žIII 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 learning 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 require two current driver's keys (black in color). 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 stamped 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.
4. Insert the key to be programmed and turn it to ON
within 10 seconds of removing the previous key.

Turn Signal/Multifunction Lever
The lever located on the left side of the steering column
includes the following:
·Turn and Lane Change Signals
·Headlamp High/Low-Beam Changer
·Flash-To-Pass
For information on the exterior lamps, see
Exterior
Lamps on page 3-16.
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 located on the
instrument panel cluster
will ¯ash in the direction of
the turn or lane change.
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. The lever returns when it is released.
If the turn signal is left on, a warning chime will sound
and the Driver Information Center (DIC) will display
TURN SIGNAL ON after driving about a mile to remind
you to turn it off.
Arrows that ¯ash rapidly when signaling for a turn or
lane change may be caused by a burned-out signal bulb.
Other drivers won't see the turn signal.
Replace burned-out bulbs to help avoid possible
accidents. Check the fuse and for burned-out bulbs if
the arrow fails to work when signaling a turn. See
Fuses
and Circuit Breakers on page 5-93.

Accessory Power Outlets
Your vehicle is equipped with accessory power outlets.
The outlets can be used to plug in electrical equipment
such as a cellular telephone, CB radio, etc.
The accessory power outlets are located at the rear of
the center console and on the lower inboard carpeted
panel on the passenger's side of the vehicle.
Your vehicle may have a small cap that must be
removed 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 outlet will only operate when the
ignition is in ACC or ON and for 10 minutes after
turning the ignition OFF. If you would like the accessory
power outlet to operate regardless of ignition position,
and for extended periods of time, see your dealer
for more information.
Notice:When using an accessory power outlet,
maximum electrical load must not exceed amperage
rating. Always turn off any electrical equipment
when not in use. Leaving electrical equipment on for
extended periods will drain your battery.Certain accessory power plugs may not be compatible
to the accessory power outlet and could result in
blown vehicle or adapter fuses. If you experience a
problem see your dealer for additional information on the
accessory power plugs.
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.
Follow the proper installation instructions that are
included with any electrical equipment you install.
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.

Electrical System
Add-On Electrical Equipment
Notice:Don't add anything electrical to your
vehicle unless you check with your dealer ®rst.
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.
Your vehicle has an air bag system. Before attempting
to add anything electrical to your vehicle, see
Servicing Your Air Bag-Equipped Vehicle on page 1-52.
Headlamp Wiring
The headlamp wiring has an individual fuse. An
electrical overload will cause the lamps to go on and off,
or in some cases to remain off. If this happens, have
the headlamp wiring checked right away.
Windshield Wiper Fuses
The windshield wiper motor is protected by an internal
circuit breaker. If the wiper motor overheats due to
heavy snow, the wipers will stop until the motor cools
and will then restart.
A fuse powers the wiper motor. If the fuse blows, there
is an electrical problem. Be sure to have it ®xed.
Power Windows and Other Power
Options
Circuit breakers protect the power windows and power
seats. When the current load is too heavy, the circuit
breaker opens and closes, protecting the circuit until the
problem is ®xed or goes away.
5-92

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. If a fuse should blow, see your dealer
for service immediately.
If you ever have a problem on the road and don't have
a spare fuse, you can ªborrowº one that has the
same amperage. Pick some feature of your vehicle that
you can get along without ± like the radio or cigarette
lighter ± and use its fuse, if it is the correct amperage.
Replace it as soon as you can.
The fuses are located in two fuse blocks, one located
near the engine compartment on the passenger's
side and the other under the rear seat on the driver's
side. If a fuse should blow, have your vehicle serviced
by your dealer immediately.
Underhood Fuse Block
The underhood fuse block is located in the front of the
engine compartment between the windshield washer
¯uid reservoir and the power steering ¯uid reservoir on
the passenger's side of the vehicle. See
Engine
Compartment Overview on page 5-12for more
information on location.
To access the fuses, push in the two tabs located at
each end of the fuse block cover. Then, lift the cover off.
