Cadillac Escalade EXT - 2007 Fuse Box Diagram

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 transition the key
to RUN, ACCESSORY or START from the OFF
position.
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
on the instrument panel 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 509
. 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.

Holding the turn signal lever for more than
one second will cause the turn signals to flash
until you release the lever. The lever will return
by itself when it is released.
An arrow on the
instrument panel
cluster will flash in
the direction of the
turn or lane change.
As you signal a turn or a lane change, if the
arrows flash more quickly than normal, a signal
bulb may be burned out and other drivers will
not see your turn signal.
If a bulb is burned out, replace it to help avoid an
accident. If the arrows do not go on at all when
you signal a turn, check for burned-out bulbs and
a blown fuse. See
Instrument Panel Fuse
Block on page 510
and
Underhood Fuse Block
on page 513
.
Turn Signal On Chime
If your turn signal is left on for more than
3/4 of a mile (1.2 km), a chime will sound at
each flash of the turn signal and the message
TURN SIGNAL ON will also appear in the
DIC. See
DIC Warnings and Messages on
page 248
. To turn the chime and message off,
move the turn signal lever to the off position.
Headlamp High/Low-Beam Changer
53
(Headlamp High/Low Beam Changer):
To
change the headlamps from low to high beam, push
the lever toward the instrument panel. To return to
low-beam headlamps, pull the multifunction lever
toward you. Then release it.
When the high beams
are on, this indicator
light on the instrument
panel cluster will
also be on.
197
Accessory Power Outlet(s)
Accessory power outlets can be used to connect
auxiliary electrical equipment, such as a cellular
telephone or CB radio.
One outlet is located in the center console. Lift
up on the lower latch located at the front of
the console lid to access the outlet.
There may also be an accessory power outlet
located on the back of the center console above
the cupholder.
To use an outlet, lift up on the spring-loaded
protective cap. When not in use, the cap
will automatically close over the outlet. The
accessory power outlet is powered at all times.
Do not try to put the cigarette lighter in any of the
accessory outlets.
Notice:
If electrical devices are left plugged
into a power outlet, the battery may drain
causing your vehicle not to start or damage to
the battery. This would not be covered by
the warranty. Always unplug all electrical
devices when turning off your vehicle.
Certain electrical accessories may not be
compatible with 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 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 before adding
electrical equipment.
When adding electrical equipment, be sure to
follow the proper installation instructions included
with the 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.
217
Ashtray(s) and Cigarette Lighter
The front ashtray and cigarette lighter are located in
the center console near the cupholders, if the
vehicle has them. Press on the access door to open
it and use the ashtray and 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 the ashtray.
To remove the ashtray, pull it from the center
console. Slide it back in and push down to be sure
it is secure.
To use the cigarette lighter, push it in all the way,
and let go. When it is ready, it will pop back
out by itself.
Notice:
Holding a cigarette lighter in while it
is heating will not allow the lighter to back
away from the heating element when it is hot.
Damage from overheating may occur to the
lighter or heating element, or a fuse could be
blown. Do not hold a cigarette lighter in
while it is heating.
Analog Clock
To adjust the clock, do the following:
1. Locate the adjustment button, near the lower
left corner of the clock.
2. Push and hold the adjustment button to
advance the clock hands. Release the
button before you get to the desired time.
3. Push and release the button to increase the
time by one minute increments until the
desired time is reached.

Trailer Wiring Harness
Heavy-Duty Trailer Wiring Package
Your vehicle is equipped with the seven-wire
trailer towing harness. This harness with a
seven-pin universal heavy-duty trailer connector is
attached to the rear bumper beam. It is located
next to the integrated trailer hitch.
The seven-wire harness contains the following
trailer circuits:
Yellow: Left Stop/Turn Signal
Dark Green: Right Stop/Turn Signal
Brown: Taillamps
White: Ground
Light Green: Back-up Lamps
Red w/ Black Stripe: Battery Feed*
Dark Blue: Trailer Brake*
*The fuses for these two circuits are installed in
the underhood electrical center, but the wires
are not connected. They should be connected by
your dealer or a qualified service technician.
If you are charging a remote (non-vehicle) battery,
press the tow/haul mode button located at the
end of the shift lever. This will boost the vehicle
system voltage and properly charge the battery.

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. For more information, see ENGINE OIL
LOW ADD OIL under
DIC Warnings and
Messages on page 248
.
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.

Electrical System
Add-On Electrical Equipment
Notice:
Do not add anything electrical to your
vehicle unless you check with your dealer
first. 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, see
Servicing Your Airbag-Equipped
Vehicle on page 84
.
Windshield Wiper Fuses
The windshield wiper motor is protected by an
internal circuit breaker and a fuse. If the motor
overheats due to heavy snow, etc., the wiper will
stop until the motor cools. If the overload is
caused by some electrical problem and not snow,
etc., be sure to get it fixed.
Power Windows and Other Power
Options
Circuit breakers protect the power windows and
other power accessories. If the current load is too
heavy, the circuit breaker opens and then
closes after a cool down period, 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.
