Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows
SRS 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.

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.
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 Light
Ifl
The charging system light
will come on briefly when
you
turn on the ignition, as
a check to show you
it’s
working. Then it will go
out.
If it stays on, or comes on while you are driving, you
may have a problem with the charging system. It could
indicate that you have a loose
drive belt or another
electrical problem. Have it checked right away. Driving
while
this light is on could drain your battery.
If you must drive a short distance with the light on, be
certain to turn
off all your accessories, such as the radio
and air conditioner.

Making lhms
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.
Thrn 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 Pontiac 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 mows 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.
Your vehicle has bulb warning lights. When you plug a
trailer lighting system into
your vehicle’s lighting
system, its bulb warning lights may not let you
know if
one of your lamps goes out.
So, when you have a trailer
lighting system plugged in, be sure to check your
vehicle and trailer lamps from time to time to be sure
they’re
all working. Once you disconnect the trailer
lamps, the bulb warning lights again can tell you if one
of your vehicle lamps is out.

Electrical System
kdd-On Electrical Equipment
NOTICE:
Don’t add anything electrical to your vehicle
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 vehicle, see “Servicing
Your
Air Bag-Equipped Vehicle” in the Index.
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 in the wiring itself.
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. Spare fuses are located
in the instrument
panel. See “Underhood Electrical Center” in the Index.
Headlamp Wiring
The headlamp wiring is protected by a circuit breaker in
the underhood electrical center. 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
system checked right away.
