2004 Oldsmobile Silhouette wiring

Notice:If you open the liftgate without checking
for overhead obstructions such as a garage
door, you could break the liftgate glass. Always
check to make sure the area above the liftgate
is clear before opening it.
{CAUTION:
It can be dangerous to drive with the liftgate
open because carbon monoxide (CO) gas can
come into your vehicle. You can't see or smell
CO. It can cause unconsciousness and even
death. If you must drive with the liftgate open
or if electrical wiring or other cable
connections must pass through the seal
between the body and the liftgate:
·Make sure all other windows are shut.
·Turn the fan on your heating or cooling
system to its highest speed and select the
control setting that will force outside air
into your vehicle. See
Climate Control
System on page 3-28.
·If you have air outlets on or under the
instrument panel, open them all the way.
See
Engine Exhaust on page 2-42.To close the liftgate, pull down on the handle, then
®rmly shut the liftgate. Don't drive with the liftgate open,
even slightly. See
Engine Exhaust on page 2-42.
A message in your instrument panel cluster will warn
you if the liftgate is not completely closed. See
Rear Hatch Ajar Warning Message on page 3-58.

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 check the
fuse. See
Bulb Replacement on page 5-50andFuses
and Circuit Breakers on page 5-101.
If you have a trailer towing option with added wiring for
the trailer lamps, the signal indicator will ¯ash at a
normal rate even if a turn signal bulb is burned
out. Check the front and rear turn signal lamps regularly
to make sure they are working.
Turn Signal On Chime
If either turn signal is left on for more than 3/4 mile
(1.2 km), a chime will sound to let the driver know to
turn it off. If you need to leave the signal on for
more than 3/4 mile (1.2 km), turn off the signal and then
turn it back on.
Headlamp High/Low-Beam Changer
To change the headlamps from high to low beam or
from low to high, pull the turn signal lever all the
way toward you and release it.When the high beams
are on, this light on the
instrument panel cluster
will also be on.
Your fog lamps will turn off when you switch to high
beams. Using your high beams in fog is not
recommended.
Flash-to-Pass
When the headlamps are off, pull the lever toward you
to momentarily switch on the high beams. This will
signal that you are going to pass. When you release
the lever, they will turn off.

Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows the air bag symbol. The system
checks the air bag's electrical system for malfunctions.
The light tells you if there is an electrical problem.
The system check includes the air bag sensor, the air
bag modules, the wiring and the diagnostic module.
For more information on the air bag system, see
Air Bag Systems on page 1-70.
This light will come on
when you start your
vehicle, and it will ¯ash
for a few seconds.
Then the light should
go out. This means the
system is ready.
If the air bag readiness light stays on after you start the
vehicle or comes on when you are driving, your air
bag system may not work properly. Have your vehicle
serviced right away.
{CAUTION:
If the air bag readiness light stays on after you
start your vehicle, it means the air bag system
may not be working properly. The air bags in
your vehicle may not in¯ate in a crash, or they
could even in¯ate without a crash. To help avoid
injury to yourself or others, have your vehicle
serviced right away if the air bag readiness light
stays on after you start your vehicle.
The air bag readiness light should ¯ash for a few
seconds when you turn the ignition key to RUN.
If the light doesn't come on then, have it ®xed so it
will be ready to warn you if there is a problem.

Following Distance
Stay at least twice as far behind the vehicle ahead as
you would when driving your vehicle without a trailer.
This can help you avoid situations that require
heavy braking and sudden turns.
Passing
You will need more passing distance up ahead when you
are towing a trailer. And, because you are a good deal
longer, you will need to go much farther beyond the
passed vehicle before you can return to your lane.
Backing Up
Hold the bottom of the steering wheel with one hand.
Then, to move the trailer to the left, just move that hand
to the left. To move the trailer to the right, move your
hand to the right. Always back up slowly and, if possible,
have someone guide you.
Making Turns
Notice:Making very sharp turns while trailering
could cause the trailer to come in contact with the
vehicle. Your vehicle could be damaged. Avoid
making very sharp turns while trailering.When you are turning with a trailer, make wider turns
than normal. Do this so your trailer will not strike
soft shoulders, curbs, road signs, trees or other objects.
Avoid jerky or sudden maneuvers. Signal well in
advance.
Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle has to have extra
wiring.
The arrows on your instrument panel will ¯ash whenever
you signal a turn or lane change. Properly hooked up,
the trailer lamps will also ¯ash, telling other drivers
you're about to turn, change lanes or stop.
When towing a trailer, the arrows on your instrument
panel will ¯ash for turns even if the bulbs on the trailer
are burned out. Thus, you may think drivers behind
you are seeing your signal when they are not. It
is important to check occasionally to be sure the trailer
bulbs are still working.

When You Are Ready to Leave After
Parking on a Hill
1. Apply your regular brakes and hold the pedal down
while you:
·Start your engine.
·Shift into a gear.
·Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the
chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when you are
pulling a trailer. See the Maintenance Schedule for more
on this. Things that are especially important in trailer
operation are automatic transaxle ¯uid, engine oil, belts,
cooling system and brake system. Each of these is
covered in this manual, and the Index will help you ®nd
them quickly. If you are trailering, it is a good idea to
review these sections before you start your trip.
Check periodically to see that all hitch nuts and bolts
are tight.
Trailer Wiring Harness
Your vehicle has a trailer wiring harness located at the
rear of your vehicle. To use the trailer wiring harness
you need a converter kit. Contact your dealer for more
information.

Headlamp Wiring
The headlamp wiring is protected by an internal circuit
breaker in the instrument panel fuse panel. An electrical
overload will cause the lamps to go on and off, or in
some cases to remain off. If this happens, have
your headlamp wiring checked right away.
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, be sure to get it ®xed.
Power Windows and Other Power
Options
Circuit breakers in the instrument panel fuse panel
protect the power windows and other power accessories.
When the current load is too heavy, the circuit breaker
opens and closes, protecting the circuit until the
problem is ®xed.
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.
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 do not have
a spare fuse, you can borrow one that has the same
amperage or use one of the spare fuses in the
underhood fuse block. Just pick some feature of your
vehicle that you can get along without Ð like the radio or
cigarette lighter Ð and use its fuse, if it is the right
amperage. Replace it as soon as you can.
There are two fuse blocks in your vehicle, the instrument
panel fuse block and the underhood fuse block.
