Cadillac Escalade - 2008 Fuse Box Diagram

Cadillac Escalade - 2008 Fuse Box Diagram

Testing the Alarm
To test the alarm:
1. From inside the vehicle, lower the driver’s window
and open the driver’s door.
2. Activate the system by locking the doors with the
power door lock switch while the door is open, or
with the RKE transmitter.
3. Get out of the vehicle, close the door and wait for
the security light to go out.
4. Then reach in through the window, unlock the door
with the manual door lock and open the door. This
should set off the alarm.
While the alarm is set, the power door unlock switch will
not work.
If the alarm does not sound when it should but the
headlamps flash, check to see if the horn works. The
horn fuse may be blown. To replace the fuse, see
Fuses
and Circuit Breakers on page 5-108
.
If the alarm does not sound or the headlamps do not
flash, the vehicle should be serviced by your
dealer/retailer.

PASS-Key
®
III+ uses a radio frequency transponder in
the key that matches a decoder in your vehicle.
2-22
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.
The system is automatically armed when the key
is removed from the ignition.
The system is automatically disarmed when the key is
turned to ON/RUN, ACC/ACCESSORY or START
from the LOCK/OFF position.
You do not have to manually arm or disarm the system.
The security light will come on if there is a problem
with arming or disarming the theft-deterrent system.
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 cluster comes on when trying to
start the vehicle, there may be a problem with your
theft-deterrent system. 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 5-108
. 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/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 10 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.

Turn and Lane-Change Signals
The turn signal has two upward (for right) and two
downward (for left) positions. These positions allow you
to signal a turn or a lane change.
To signal a turn, move the lever all the way up or down.
When the turn is finished, the lever will return
automatically.
To signal a lane change, raise or lower the lever for
less than one second until the arrow starts to flash. This
will cause the turn signals to automatically flash three
times. It will flash six times if tow-haul mode is
active. 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
Fuses and Circuit Breakers on page 5-108
.
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 Driver Information Control (DIC). To
turn the chime and message off, move the turn
signal lever to the off position.

Accessory Power Outlet(s)
The accessory power outlets let you plug in auxiliary
electrical equipment, such as a cellular telephone or
CB radio.
Your vehicle has one accessory power outlet inside the
floor console storage bin, one on the back of the
floor console, and one power outlet in the rear cargo
area on the passenger side.
To use an accessory power outlet, remove the protective
cap. When not in use, always cover the accessory
power outlet with the protective cap.
Certain power accessory plugs may not be compatible
to the accessory power outlet and could result in
blown adapter or vehicle fuses. If you experience a
problem, see your dealer/retailer for additional
information on the accessory power plugs.
The accessory power outlets are powered, even when
the ignition is in LOCK/OFF. Continuing to use
power outlets while the ignition is in LOCK/OFF may
cause the vehicle’s battery to run down.
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.
When adding electrical equipment, be sure to follow the
proper installation instructions included with the
equipment. Do not use equipment exceeding the
maximum amperage rating of 20 amperes.
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
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 does not let the lighter back away from the
heating element when it is hot. Damage from
overheating can 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
The analog clock is not connected with any other
vehicle system and runs by itself.
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. Holding the button down will
cause the clock to advance faster. 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.

Electrical System
Add-On Electrical Equipment
Notice:
Do not add anything electrical to your
vehicle unless you check with your dealer/retailer
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 1-90
.
Windshield Wiper Fuses
The windshield wiper motor is protected by a 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,
have 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.
