Cadillac DTS - 2006 Fuse Box Diagram

Cadillac DTS - 2006 Fuse Box Diagram

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 5-93
. 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.

PASS-Key
®
III+ uses a radio frequency transponder in
the key that matches a decoder in your vehicle.
PASS-Key
®
III+ Operation
Your vehicle has 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 special to arm
or disarm the system. It works when you insert or
remove the key from the ignition or transition the key
from run, accessory or start from the off position.
2-21
When the PASS-Key
®
III+ system senses that someone
is using the wrong key, it prevents the vehicle from
starting. Anyone using a trial-and-error method to start
the vehicle will be discouraged because of the high
number of electrical key codes.
If the engine does not start and the security light comes
on when trying to start the vehicle, the key may have
a damaged transponder. Turn the ignition off and
try again.
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, see
Fuses
and Circuit Breakers on page 5-93
. 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. 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 or a locksmith who can service PASS-Key
®
III+
to have keys made and programmed to the system.
See your dealer 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 do the following:
1. Verify that the new key has a
+
stamped 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 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 five seconds of removing
the original key.
5. The security light will turn off once the key has
been programmed.
6. Repeat Steps 1 through 5 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.
If you lose or damage your PASS-Key
®
III+ key,
see your dealer or a locksmith who can service
PASS-Key
®
III+ to have a new key made.

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. If you momentarily press and release the
lever, the turn signal will flash 3 times.
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 5-96
.

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. 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.
Ashtray(s) and Cigarette Lighter
Notice:
If you put papers, pins, 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

Engine Oil
If the ENGINE OIL LOW ADD OIL message appears on
the Driver Information Center (DIC), it means you
need to check your engine oil level right away. See
“ENGINE OIL LOW ADD OIL” under
DIC Warnings and
Messages on page 3-76
.
You should check your engine oil level regularly; this is
an added reminder.
Checking Engine Oil
It is a good idea to check your 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 5-12
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.
5-13
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.
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 6-12
.
Always use the proper fluid. Failure to use the proper
fluid can cause leaks and damage hoses and seals.
5-33
The battery is located under the rear seat cushion. To
access the battery, see
Rear Underseat Fuse Block on
page 5-96
. You do not need to access the battery to jump
start your vehicle. See
Jump Starting on page 5-39
.
{
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.
To be sure the vent hose (A) is properly attached, the
vent hose connectors (B) must be securely reattached to
the vent outlets (C) on each side of the battery, and
the vent assembly grommet (D) must be secured to the
floor pan (E).
5-38
2. Get the vehicles close enough so the jumper cables
can reach, but be sure the vehicles are not touching
each other. If they are, it could cause a ground
connection you do not want. You would not be able
to start your vehicle and the bad grounding could
damage the electrical systems.
To avoid the possibility of the vehicles rolling, set
the parking brake firmly on both vehicles involved in
the jump start procedure. 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 5-12
for more information on the location
of the remote positive (+) terminal.
A second remote positive (+) terminal is located on
the rear underseat fuse block.
The remote negative (
) terminal is located behind
the power steering pulley, near the engine cover.
It is marked GND (
).

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 1-70
.
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.
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 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 on the passenger’s
side of the engine compartment. Remove the fuse
cover and secondary service cover to access the
fuse block.
