Cadillac CTS-V - 2007 Fuse Box Diagram

Cadillac CTS-V - 2007 Fuse Box Diagram

To avoid activating the alarm by accident do the
following:
Lock the door with the 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
RKE transmitter. 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, or by starting the vehicle with
a valid key.
Testing the Alarm
1. 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 switch or the RKE transmitter and
close the door. Wait approximately 30 seconds
until the security light goes off.
3. Reach in and unlock the door using the
manual lock and open the door. The horn
will sound and the exterior lamps will flash.
The alarm can be turned off by unlocking the
driver’s door with the 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, see
Fuses and Circuit
Breakers on page 447
. 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.
108
When trying to start the vehicle, if the engine does
not start and the security light comes on, 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 447
. 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 theft-deterrent
system and have a new key made.
It is possible for the theft-deterrent system decoder
to learn the transponder value of a new or
replacement key. Up to 10 additional keys may be
programmed for the vehicle. The following
procedure is for programming additional keys only.
Canadian Owners:
If you lose or damage your
keys, only a GM dealer can service the
theft-deterrent system to have new keys made.
To program additional keys you will require two
current driver’s keys. You must add a step to the
following procedure. After Step 2, repeat Steps 1
and 2 with the second current driver’s key. Then
continue with Step 3.
To program a new key do the following:
1. Verify that the new key has PK3+
stamped on it.
2. Insert the current driver’s 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 key to be programmed and turn it to
ON within ten seconds of removing the
previous key.
5. The security light will turn off once the key
has been programmed. It may not be
apparent that the security light went on due to
how quickly the key is programmed.
6. Repeat the Steps 1 through 4 if additional
keys are to be programmed.
If the security light comes on and stays on while
driving, you will be able to restart the engine if you
turn it off. The theft-deterrent system, however,
is not working properly and must be serviced
by your dealer. Your vehicle is not protected by
the theft-deterrent system at this time.

Engine Coolant Heater
Your vehicle may have an engine coolant heater.
In very cold weather, 0°F (
18°C) or colder,
the engine coolant heater can help. You will get
easier starting and better fuel economy during
engine warm-up.
Usually, the coolant heater should be plugged in a
minimum of four hours prior to starting your
vehicle. At temperatures above 32°F (0°C), use of
the coolant heater is not required. Your vehicle
may also have an internal thermostat in the
plug end of the cord. This will prevent operation of
the engine coolant heater when the temperature
is at or above 0°F (
18°C) as noted on the cord.
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical
cord. For the 2.8L V6 and the 3.6L V6
engines, the cord is located in the engine
compartment on the passenger’s side of the
vehicle in front of the fuse block. For the
6.0L V8 engine, the cord is located in
the engine compartment on the driver’s side
of the vehicle near the inner fender and above
the strut.
Remove the plastic cap to access the plug.
3. Plug it into a normal, grounded 110-volt AC
outlet.

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.
An arrow on the
instrument panel cluster
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 to its
original position when it is released.
Rapid flashing of arrows when signaling for a turn
or lane change may be caused by a burned-out
signal bulb. Other driver’s will not see the 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
Fuses and Circuit Breakers on page 447
for
more information.

Accessory Power Outlet(s)
Accessory power outlets can be used to connect
auxiliary electrical equipment, such as a cellular
telephone or CB radio.
There are two accessory power outlets. The front
accessory power outlet is located in the ashtray
on the instrument panel below the climate control
system. The outlet will have a cigarette lighter
if your vehicle has this option. Remove the
cigarette lighter to access the outlet.
The rear accessory power outlet is located on the
back of the center console.
To use an outlet, remove the protective cap.
When not in use, always cover the outlet with the
protective cap. The accessory power outlet is
operational at all times.
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.
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.

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. See
Engine Compartment
Overview on page 342
for battery location.
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.
{
CAUTION:
Batteries have acid that can burn you and
gas that can explode. You can be badly
hurt if you are not careful. See
Jump
Starting on page 377
for tips on working
around a battery without getting hurt.
After a power loss, such as disconnecting the
battery or removing the maxi fuses in the power
distribution fuse block, the following steps must
be performed to calibrate the electronic throttle
control. If this is not done, the engine will not run
properly.
1. Turn the ignition key to ON. Do not start the
engine.
2. Leave the ignition in ON for at least three
minutes so that the electronic throttle
control will cycle and re-learn its home
position.
3. Turn the ignition to OFF.
4. Start and run the engine for at least
30 seconds.
376
Your vehicle has a remote negative (
) ground
location, as shown in the illustration. It is
located between the battery and the underhood
fuse block. You should always use this remote
ground location, instead of the terminal on the
battery.
Notice:
If you connect a negative cable to the
ECM, ECM mounting bracket, or any cables
that attach to the ECM bracket, you may
damage the ECM. Always attach the negative
cable to your vehicle’s remote negative ground
location, instead of the ECM, ECM bracket,
or any cables attached to the ECM bracket.
{
CAUTION:
An electric fan can start up even when the
engine is not running and can injure you.
Keep hands, clothing and tools away from
any underhood electric fan.
379
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. If the wiper motor
overheats due to heavy snow, the wipers will stop
until the motor cools and will then restart.
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.
446
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 blows,
see your dealer for service immediately.
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. 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 three fuse blocks, one
located in the engine compartment on the
passenger’s side and the other two under the
rear seat.
Underhood Fuse Block
The underhood fuse block is located in the engine
compartment on the passenger’s side of the
vehicle. See
Engine Compartment Overview on
page 342
for more information on location.
To access the fuses, push in the two tabs located
on each side of the fuse block cover. Then lift
the cover off.
