Cadillac DTS - 2007 Fuse Box Diagram

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 443
. 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.

Engine Oil
Checking Engine Oil
It is a good idea to check the engine oil every time
you get fuel. In order to get an accurate reading,
the oil must be warm and the vehicle must be
on level ground.
The engine oil dipstick handle is a yellow loop.
See
Engine Compartment Overview on page 356
for the location of the engine oil dipstick.
1. Turn off the engine and give the oil several
minutes to drain back into the oil pan. If you
do not do this, the oil dipstick might not
show the actual level.
2. Pull out the dipstick and clean it with a paper
towel or cloth, then push it back in all the
way. Remove it again, keeping the tip down,
and check the level.
357
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 356
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.
How to Check Power Steering Fluid
To check the power steering fluid, do the following:
1. Turn the key off and let the engine
compartment cool down.
2. Wipe the cap and the top of the reservoir clean.
3. Unscrew the cap and wipe the dipstick with a
clean rag.
4. Replace the cap and completely tighten it.
5. Remove the cap again and look at the
fluid level on the dipstick.
The level should be at the FULL COLD mark.
If necessary, add only enough fluid to bring
the level up to the mark.
What to Use
To determine what kind of fluid to use, see
Recommended Fluids and Lubricants on page 467
.
Always use the proper fluid. Failure to use the
proper fluid can cause leaks and damage hoses
and seals.
377
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 447
. You do not need to
access the battery to jump start your vehicle.
See
Jump Starting on page 384
.
{
CAUTION:
A battery that is not properly vented
can let sulfuric acid fumes into the area
under the rear seat cushion. These fumes
can damage your rear seat safety belt
systems. You may not be able to see this
damage, and the safety belts might not
provide the protection needed in a crash.
If a replacement battery is ever needed,
it must be vented in the same manner as
the original battery. Always make sure
that the vent hose is properly reattached
before reinstalling the seat cushion.
382
Put an automatic transaxle in PARK (P) or
a manual transaxle in NEUTRAL before
setting the parking brake.
Notice:
If you leave your radio or other
accessories on during the jump starting
procedure, they could be damaged. The repairs
would not be covered by your warranty.
Always turn off your radio and other
accessories when jump starting your vehicle.
3. Turn off the ignition on both vehicles.
Unplug unnecessary accessories plugged into
the cigarette lighter or the accessory power
outlets. Turn off the radio and all lamps
that are not needed. This will avoid sparks
and help save both batteries. And it could
save the radio!
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. Lift the red plastic
cap to access the terminal. See
Engine
Compartment Overview on page 356
for more
information on the location of the remote
positive (+) terminal.
A second remote positive (+) terminal is
located on the rear underseat fuse block.

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.
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.
443
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.
