if
electrical wiring or other cable connections must
pass through the seal between the body and the
trunk lid:
Make sure all windows are shut.
0 ’hrn the fan on your heating or cooling

Downloaded from www.Manualslib.com manuals search engine Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows AIR BAG. 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 sensors, the air bag modules,
the wiring and the crash sensing and diagnostic module.
For more information on the air bag system, see “Air
Bag” in the Index.
AIR BAG
This light will come on
when you start your engine, and it will flash for a few
seconds. Then the light
should go out. This means
the system is ready. The
air bag readiness light should flash for a
few
seconds when you turn the ignition key to RUN. If the
light doesn’t come on then, have it fixed
so it will be
ready to warn you if there
is a problem.
Charging System Indicator Light
When you turn the key to
RUN, this light will come
on briefly
to show that
the generator and battery charging systems
are working.
If this light stays on, you need service and you should
take your Cadillac to the dealer at once.
To save your
battery until you get there, turn
off all accessories.
If the air bag readiness light stays on after you start the
engine or comes on when you
are driving, your air bag
system may not work properly. Have your vehicle
serviced right away.

If your vehicle is equipped with the 3,666-&. (1 360 kg)
trailer towing package option, you will have a wiring
harness located under the trunk trim. The harness is a
five wire harness, with connector.
These trailer-wiring harness color codes should be
followed when connecting it to your trailer:
0 WHITE: Direct trailer ground for trailer lamps.
0 BROWN: Parking lamps.
0 YELLOW Left turn and stoplamps.
0 GREEN: Right turn and stoplamps.
BLUE: Auxiliary circuit.
Driving with a Trailer
Towing a trailer requires a certain amount of experience.
Before setting out for the open road, you’ll want to get
to know your rig. Acquaint yourself with the feel
of
handling and braking with the added weight of the
trailer. And always keep in mind that the vehicle you are driving is now a good deal longer and not nearly as
responsive as your vehicle
is by itself.
Before you
start, check the trailer hitch and platform
(and attachments), safety chains, electrical connector,
lamps, tires and mirror adjustment.
If the trailer has
electric brakes, start your vehicle and trailer moving and
then apply the trailer brake controller by hand to be sure
the brakes are working. This lets you check your
electrical connection at the same time.
During your trip, check occasionally to be sure that the
load is secure, and that the lamps and any trailer brakes are still working.
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.

Downloaded from www.Manualslib.com manuals search engine Passing
You’ll need more passing distance up ahead when
you’re towing
a trailer. And, because you’re a good deal
longer, you’ll 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’re turning with a trailer, make wider turns
than normal.
Do this so your trailer won’t 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 may need a
different turn signal flasher and/or extra wiring. Check
with your Cadillac dealer. The green arrows on your
instrument panel will flash whenever you signal a turn or lane change. Properly hooked up, the trailer lamps
will also flash, telling other drivers you’re about to turn,\

change lanes or stop.
When towing a trailer, the green arrows on your
instrument panel will flash 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’s
important to check occasionally to be sure the trailer
bulbs are still working.
Driving On Grades
Reduce speed and shift to a lower gear before you start
down a long or steep downgrade. If you don’t shift
down, you might have to use your brakes
so much that
they would get hot and no longer work well.
On a long uphill grade, shift down and reduce your
speed to around
45 mph (70 km/h) or less to reduce the
possibility of engine and transaxle overheating.

2. Turn the headlamp housing socket counterclockwise
to unlock the socket from the lamp housing. 3. Disconnect the socket from the harness by separating
the locking
clip.
4. Install the new bulb and socket to the wiring harness
connector. Make sure that the harness is locked to the
bulb socket.

Add-on Electrical Equipment
NOTICE:
Don’t add anything electrical to your Cadillac
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 air bag system. Before attempting to
add anything electrical to your Cadillac, see “Servicing
Your Air Bag-Equipped Cadillac” in the Index.
Headlamp Wiring
The headlamp wiring has an individual fuse which is
powered by a MaxiFuse@. 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.
MaxiFuse
is a registered trademark of Little
Fuse Incorporated.
Windshield Wiper Fuses
The windshield wiper motor is powered by a MaxiFuse.
If
the motor overheats due to heavy snow, etc., the
wipers will stop until the motor cools. If the overload
is caused by some electrical problem, be
sure to have
it fixed.
Power Windows and Other Power Options
Circuit breakers 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 fixed or goes away.

Downloaded from www.Manualslib.com manuals search engine 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 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.
There are two fuse blocks in your vehicle: the engine
compartment fuse block and the rear compartment
fuse block.
Engine Compartment Fuse Block
The fuse block is located next to the air cleaner on the
driver’s side
of the engine. Lift the cover to gain access.
