2007 CADILLAC DTS fuses

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 RKE transmitter.
To avoid activating the alarm by accident:
Lock the vehicle with the door key or the
manual door lock after the doors are closed.
Always unlock a door with a key or use the
RKE transmitter system. Pressing the unlock
button on the RKE 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 RKE transmitter system, or by starting the car
with a valid key.
Changes or modications 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 RKE 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 ash.
You can turn off the alarm by unlocking the driver’s
door with your key, using the unlock button on
the RKE 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, seeFuses and Circuit
Breakers on page 452. 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.

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,
seeFuses and Circuit Breakers on page 452.Ifthe
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/retailer who
can service the PASS-Key
®III+ to have a new key
made. In an emergency, contact Roadside
Assistance.
It is possible for the PASS-Key
®III+ decoder to
“learn” the transponder value of a new or
replacement key. Up to nine additional keys may be
programmed for the vehicle. The following
procedure is for programming additional keys only.
If all the currently programmed keys are lost or do
not operate, you must see your dealer/retailer or a
locksmith who can service PASS-Key
®III+ to have
keys made and programmed to the system.
See your dealer/retailer or a locksmith who can
service PASS-Key
®III+ to get a new key blank that
is cut exactly as the ignition key that operates the
system.To program the new key:
1. Verify that the new key has a
1stamped
on it.
2. Insert the original, already programmed, key
in the ignition and start the engine. If the
engine will not start, see your dealer/retailer
for service.
3. After the engine has started, turn the key to
OFF, and remove the key.
4. Insert the new key to be programmed
and turn it to the RUN position within
ve seconds of removing the original key.
The security light will turn off once the key has
been programmed.
5. Repeat Steps 1 through 4 if additional keys
are to be programmed.
If you are driving and the security light comes on
and stays on, you may be able to restart your
engine. Your PASS-Key
®III+ system, however,
may not be working properly and must be serviced
by your dealer/retailer.

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.
If your vehicle has a stationary center console,
the power outlet is located inside the lower storage
area. There are outlets also on the right front
lower part of the driver’s seat and in the lower
storage bin. SeeCenter Console Storage Area
on page 155.
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 can be used at
any time.
Notice: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 unplugelectrical 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.
Do not hang any type of accessory or
accessory bracket from the plug because the
power outlets are designed for accessory
power plugs only.

Electrical System
Add-On Electrical Equipment
Notice:Do not add anything electrical to your
vehicle unless you check with your dealer
rst. Some electrical equipment can damage
your vehicle and the damage would not
be covered by your warranty. Some add-on
electrical equipment can keep other
components from working as they should.
Add-on equipment can drain your vehicle’s battery,
even if your vehicle is not operating.
Your vehicle has an airbag system. Before
attempting to add anything electrical to your
vehicle, seeServicing Your Airbag-Equipped
Vehicle on page 86.
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 xed.
451

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.
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 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 on the
passenger’s side of the engine compartment.
Remove the fuse cover and secondary service
cover to access the fuse block.
