Cadillac STS - 2005 Fuse Box Diagram

Cadillac STS - 2005 Fuse Box Diagram

The Theft-Deterrent system will not arm if:
The key is used to lock the driver’s door.
The driver’s door is locked using the power door
lock switch after the doors are closed.
If the vehicle is locked using the keyless access
transmitter and a door, trunk lid or hood is open or not
closed completely, the security light will flash for 60
seconds and then go off. At this time the theft-deterrent
system will be armed but door, trunk lid or hood that
was open or not completely closed will not trigger
an alarm event. The door, trunk lid or hood that was
completely closed will still be armed and will trigger a
theft event if they are opened or tampered with.
The vehicle can be programmed to automatically unlock
the doors when you approach the vehicle and the
keyless access transmitter is with you. See
Vehicle
Personalization on page 2-47
.
Pressing the unlock button on the keyless access
transmitter or using the key to unlock the driver’s door
disarms the theft-deterrent system. Unlocking a door
any other way while the system is armed will activate
the alarm.
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 switch
or the Keyless Access transmitter and close
the door. Wait approximately 30 seconds until the
security light goes off.
3. Reach in and unlock the door using the power door
lock switch and open the door. The horn will sound
and the exterior lamps will flash.
You can turn off the alarm by pressing the unlock
button on the keyless access transmitter or by starting
the car.
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.

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 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 to its original
position when it’s released.
Arrows that flash rapidly when signaling for a turn or
lane change may be caused by a burned-out signal bulb.
Other driver’s won’t see the 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
for more information.

As light shines out from the HUD, it is possible for light
to shine back in. In rare occurrences, when the sun
is at a specific angle and position, the sun’s rays can
shine back into the HUD. When this occurs, the display
device within the HUD will be temporarily illuminated.
The event will end when the vehicle’s angle to the
sun changes.
Clean the inside of the windshield as needed to remove
any dirt or film that reduces the sharpness or clarity
of the HUD image.
To clean the HUD, spray household glass cleaner
on a soft, clean cloth. Wipe the HUD lens gently, then
dry it.
Notice:
When cleaning, be careful not to
scratch the HUD or camera lenses. Do not spray
glass cleaner directly on the HUD lens because
the cleaner could leak inside the unit and
cause damage.
If the ignition is on and you cannot see the HUD image,
check to see if:
Something is covering the HUD unit.
The brightness is adjusted properly.
The HUD image is adjusted to the proper height.
Ambient light in the direction your vehicle is facing
is low.
A fuse is blown. See
Fuses and Circuit Breakers on
page 5-93
.
Keep in mind that your windshield is part of the HUD
system. If you ever have to have your windshield
replaced, be sure to get one that is designed for HUD
or your HUD image may look blurred and out of focus.
The following Adaptive Cruise Control message may
appear in the HUD:
PEDAL APPLIED ACC OVERRIDE:
This message
indicates that you are pressing your foot on the
accelerator pedal and overriding Adaptive Cruise
Control. While you are doing this, the system will not
automatically apply the brakes. Once you remove your
foot from the accelerator pedal, Adaptive Cruise
Control will return to normal operation and be able to
apply the brakes, if needed.
You may also see an Adaptive Cruise Control
active symbol, alert symbol or vehicle ahead
symbol. See
Adaptive Cruise Control on page 3-19
for more information.

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.
Your vehicle has one outlet in front of the center
console, one in the center console lid and there may be
an additional outlet in the rear of the center console.
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.
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.
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
Your vehicle may have an ashtray 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

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 1-56
.
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.
5-92
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.
Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses, circuit breakers
and fusible thermal links. 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 don’t have
a spare fuse, you can borrow one that has the same
amperage. Just 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 three fuse blocks. One is
located in the engine compartment, on the passenger’s
side of the vehicle, and the other two are located
under the rear seat on both the driver’s and passenger’s
side of the vehicle.
5-93
Underhood Fuse Block
5-94
The underhood fuse block is located in the front of the
engine compartment on the passenger’s side of the
vehicle. See
Engine Compartment Overview on
page 5-12
for more information on location, and removal
procedure for the front compartment underhood sights
shields.
To access the fuses, push in the tabs located on each
side of the fuse block cover. Then, lift the cover off.
