Cadillac STS - 2008 Fuse Box Diagram

Cadillac STS - 2008 Fuse Box Diagram

If the vehicle is locked using the keyless access
transmitter and the trunk lid, hood or a door is open or
not closed completely, the security light will flash for
60 seconds and then turn off. At this time, the
theft-deterrent system is armed but the alarm will not
sound if the trunk lid, hood or door that was not closed
completely is tampered with or opened. The alarm
will sound for the trunk lid, hood or a door that was
completely closed at the time the vehicle was locked
using the keyless access transmitter.
The vehicle can be programmed to automatically unlock
the doors and disarm the theft-deterrent system when
you approach the vehicle and the keyless access
transmitter is with you. See
Vehicle Personalization
on page 2-60
.
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 about 30 seconds until the security light
goes off.
3. Reach in and open the door using the inside door
handle. 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 5-117
. 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.
Do not leave the key or device that disarms or
deactivates the theft deterrent system in the vehicle.
2-24
If the vehicle does not start and the keyless access
transmitter appears to be undamaged, try another
keyless access transmitter. Or, you may try placing the
transmitter in the transmitter pocket. See “NO FOBS
DETECTED” under
DIC Warnings and Messages
on page 3-80
for additional information. At this time,
you may also want to check the fuse. See
Fuses and
Circuit Breakers on page 5-117
. If the engine still
does not start with the other transmitter, your vehicle
needs service. If the engine does start, the first
transmitter may be faulty. See your dealer/retailer
who can service the theft-deterrent system and have
a new keyless access transmitter programmed to
the vehicle.
It is possible for the immobilizer system to learn new
or replacement keyless access transmitters. Up to
4 keyless access transmitters can be programmed for
the vehicle. To program additional transmitters, see
“Matching transmitter(s) to Your Vehicle” under
Keyless
Access System Operation on page 2-6
.
Do not leave the key or device that disarms or
deactivates the theft deterrent system in the vehicle.
Starting and Operating
Your Vehicle
New Vehicle Break-In
Notice:
Your vehicle does not need an elaborate
break-in. But it will perform better in the long run if
you follow these guidelines:
Do not drive at any one constant speed, fast or
slow, for the first 500 miles (805 km). Do not
make full-throttle starts. Avoid downshifting to
brake or slow the vehicle.
Avoid making hard stops for the first 200 miles
(322 km) or so. During this time the new brake
linings are not yet broken in. Hard stops
with new linings can mean premature wear and
earlier replacement. Follow this breaking-in
guideline every time you get new brake linings.
Do not tow a trailer during break-in. See
Towing
a Trailer (Vehicles With Heavy Duty Cooling) on
page 4-34
or
Towing a Trailer (Vehicles Without
Heavy Duty Cooling) on page 4-40
for the trailer
towing capabilities of your vehicle and more
information.
Following break-in, engine speed and load can be
gradually increased.
2-27
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 5-117
.
The windshield is part of the HUD system.
See
Windshield Replacement on page 5-55
.
The following Adaptive Cruise Control message
may appear in the HUD:
The PEDAL APPLIED ACC OVERRIDE message
indicates that you are pressing your foot on the
accelerator pedal and overriding Adaptive Cruise
Control. While this is being done, 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.
An Adaptive Cruise Control active symbol, alert symbol
or vehicle ahead symbol may also appear. See
Adaptive
Cruise Control on page 3-20
for more information.
Accessory Power Outlet(s)
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.
3-46

Leaving electrical equipment plugged in for
an extended period of time while the vehicle is off
will drain the battery. Power is always supplied
to the outlets. Always unplug electrical equipment
when not in use and do not plug in equipment
that exceeds the maximum 20 ampere 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. Do not use
equipment exceeding maximum amperage rating
of 20 amperes. Check with your dealer/retailer
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.

If the vehicle has an oil problem, this light may stay
on after the engine is started, or come on while you
are driving.
This light indicates that oil is not going through the engine
quickly enough to keep it lubricated. The engine could
be low on oil or could have some other oil problem.
Have it fixed right away.
The oil light could also come on in the following
situations:
The light will come on briefly when the ignition
is turned on to show that it is working properly.
If it does not come on with the ignition on,
there may be a problem with the fuse or bulb.
Have it fixed right away.
Sometimes when the engine is idling at a stop,
a chime will sound and the light may blink on
and off. This is normal.
{
CAUTION:
Do not keep driving if the oil pressure is low.
If you do, your engine can become so hot that
it catches fire. You or others could be burned.
Check your oil as soon as possible and have
your vehicle serviced.
Notice:
Lack of proper engine oil maintenance may
damage the engine. The repairs would not be covered
by your warranty. Always follow the maintenance

If your vehicle is equipped with front compartment
underhood sight shields, before closing the hood be sure
to reinstall the sight shields. To reinstall the shields,
locate the tabs on the left and right sides and insert
them into the openings in the tower to tower brace. Then
insert the fasteners into the top of the shield and push
the fasteners back into place.
5-17
Headlamp Wiring
The headlamp wiring is protected by fuses in the fuse
block. An electrical overload will cause the lamps to turn
off. If this happens, have your 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.
Power Windows and Other Power
Options
Circuit breakers in the 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, 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 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.
5-117
Underhood Fuse Block
5-118
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 5-11
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.
Notice:
Spilling liquid on any electrical components
on your vehicle may damage it. Always keep the
covers on any electrical component.
