Cadillac DeVille - 2005 Fuse Box Diagram

Cadillac DeVille - 2005 Fuse Box Diagram

If a door or the trunk is opened without a key or a
remote keyless entry transmitter, the horn will sound
and the lamps will flash for about 30 seconds.
Remember, the theft-deterrent system will not arm if you
lock the doors with a key or use the manual door
lock. It activates only if you use a power door lock with
the door open or the remote keyless entry transmitter.
To avoid activating the alarm by accident do the
following:
The vehicle should be locked with the door key or
the manual door lock after the doors are closed if
you do not want to arm the theft-deterrent system.
Always unlock a door with a key or use the remote
keyless entry transmitter system. Pressing the
unlock button on the remote keyless entry
transmitter disables the theft-deterrent system.
Unlocking a door any other way will activate
the alarm when a door or the trunk is opened.
If you activate the alarm by accident, unlock the driver’s
door with your key. You can also turn off the alarm by
using the unlock button on the remote keyless entry
transmitter system, or by starting the car with a valid key.
Changes or modifications made to this system by other
than an authorized service facility could void
authorization to use the theft system.
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 system 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 flash.
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 5-98
. 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.

PASS-Key
®
III Operation
Your vehicle is equipped with the PASS-Key
®
III
(Personalized Automotive Security System)
theft-deterrent system. PASS-Key
®
III is a passive
theft-deterrent system. This means you do not have to
do anything different to arm or disarm the system. It
works when you insert or remove your key from
the ignition.
When the PASS-Key
®
III 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 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 5-98
. If the engine still
does not start with the other key, your vehicle needs
service. If your 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.
It is possible for the PASS-Key
®
III 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.

.
Turn and Lane-Change Signals
To signal a turn, move the lever all the way up or down.
The lever returns automatically when the turn is
complete.
An arrow on the instrument
panel cluster and in the
outside rearview mirror will
flash in the direction of
the turn or lane change.
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. 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 flash rapidly when signaling for a turn or
lane change may be caused by a burned out signal bulb.
Other drivers will not 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
Rear
Underseat Fuse Block on page 5-101
.
3-8
It may also flash red if the ultrasonic sensors are not
kept clean. So be sure to keep your rear bumper free of
mud, dirt, snow, ice and slush or materials such as
paint or the system may not work properly. If after
cleaning the rear bumper and driving forward at least
15 mph (25 km/h), the display continues to flash red, see
your dealer. For cleaning instructions, see
Washing
Your Vehicle on page 5-91
.
It may also flash red if your vehicle is moving in
REVERSE (R) at a speed greater than 3 mph (5 km/h).
Other conditions that may affect system performance
include things like the vibrations from a jackhammer or
the compression of air brakes on a very large truck.
As always, drivers should use care when backing up a
vehicle. Always look behind you, being sure to check
for other vehicles, obstructions and blind spots.
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.
If you have a vehicle with a center storage compartment
located on the instrument panel, you may have an
accessory power outlet in the storage drawer. There is
also an outlet on the front passenger’s seat near
the umbrella tray.
There are two accessory power outlets in the rear seat
area located on the door armrests next to the ashtrays.
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 ACCESSORY 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:
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 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 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. Check with your
dealer before adding electrical equipment.
3-28
Follow the proper installation instructions that are
included with any electrical equipment you install.
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.
Ashtrays and Cigarette Lighter
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.
Front Ashtray
With the full floor console, the ashtray is located below
the climate control system. To open, push down on
the cover. To clean the ashtray, lift it out by gripping
the sides.
For vehicles without the floor console, pull the tray
located below the radio to reveal the ashtray. The
ashtray can be removed for cleaning.
Rear Ashtray
The ashtrays are located on the door armrests. To use
an ashtray, lift the lid.
Cigarette Lighter
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 anything other than the cigarette lighter in the
heating element.
The cigarette lighter is located near the front ashtray.
Press the lighter all the way in and release it. It will pop
back out by itself once the element has heated for use.
Cigarette lighters can be used to provide electrical
power to accessories. See
Accessory Power Outlets on
page 3-28
for more information.

4. With the coolant surge tank pressure cap off, start
the engine and let it run until you can feel the upper
radiator hose getting hot. Watch out for the
engine cooling fans.
By this time, the coolant level inside the coolant
surge tank may be lower. If the level is lower, add
more of the proper mixture to the coolant surge tank
until the level reaches about 4.5 inches (11.4 cm)
from the top of the filler neck.
5. Then replace the pressure cap. Be sure the arrow
on the pressure cap lines up with the tube.
Start the engine and allow it to warm up. If the CHECK
COOLANT LEVEL message does not appear on the
Driver Information Center (DIC), coolant is at the proper
fill level. If a CHECK COOLANT LEVEL message
does appear, repeat Steps 1 to 3 then reinstall the
pressure cap, or see your dealer.
Power Steering Fluid
The power steering fluid
reservoir is located next to
the underhood fuse
block on the passenger’s
side of the vehicle.
See
Engine Compartment
Overview on page 5-12
for more information
on location.
When to Check Power Steering Fluid
It is not necessary to regularly check power steering fluid
unless you suspect there is a leak in the system or
you hear an unusual noise. A fluid loss in this system
could indicate a problem. Have the system inspected
and repaired.
5-35
Brake Pedal Travel
See your dealer if the brake pedal does not return to
normal height, or if there is a rapid increase in
pedal travel. This could be a sign of brake trouble.
Brake Adjustment
Every time you apply the brakes, with or without the
vehicle moving, your brakes adjust for wear.
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 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
Rear Underseat Fuse Block on
page 5-101
. You do not need to access the battery to
jump start your vehicle. See
Jump Starting on page 5-42
.
5-40
4. Open the hoods and locate the positive (+) and
negative (
) terminal locations on the other
vehicle. Your vehicle has a remote positive (+) jump
starting terminal and a remote negative (
) jump
starting terminal.
The remote positive (+)
terminal is located in the
engine compartment
on the passenger’s side of
the vehicle. A second
remote positive (+) terminal
is located on the rear
underseat fuse block. Lift
the red plastic cap to
access the terminal.
The remote negative (
) terminal is located near
the power steering fluid reservoir. It is marked
GND (
). See
Engine Compartment Overview on
page 5-12
for more information on location.
You will not see the battery of your vehicle under
the hood. It is located under the rear passenger’s
seat. You will not need to access the battery
for jump starting. The remote positive (+) terminal is
for that purpose.
{
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.
5-44
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.
Your vehicle has an airbag system. Before attempting to
add anything electrical to your vehicle, see
Servicing
Your Airbag-Equipped Vehicle on page 1-54
.
Headlamp Wiring
The headlamp wiring system has four individual fuses.
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 fixed.
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 fixed or goes away.
5-97
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. If a fuse should blow, see your dealer
for service immediately.
If you ever have a problem on the road and do not have
a spare fuse, you can “borrow” 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 in
the engine compartment, and the other under the
rear seat. If a fuse should blow, have your vehicle
serviced by your dealer immediately.
Underhood Fuse Block
The underhood fuse block
is located next to the
engine on the passenger’s
side of the vehicle. For
more information on
location, see
Engine
Compartment Overview on
page 5-12
.
To access the fuses, push in the two tabs located at
each end of the fuse block cover. Then lift the cover off.
