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 sensor, 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.
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
This light should come on
briefly
when you turn on the
ignition, before starting the
engine,
as a check to show
you it is working.
After the engine starts, the light should
go out. If it stays
on or comes on while you are driving, you may have a
problem with your charging system. It could indicate a
problem with the alternator drive belt, or some other
charging system problem. Have it checked right away.
Driving while this light is on could drain your battery.
If you must drive a short distance with this light
on, it
helps to turn off all your accessories, such as the radio
and air conditioner.

1 VOLTS I
W
When your engine is not
running, but
the ignition is
on (in the RUN position),
this gage shows your
battery’s
state of charge in
DC volts.
When the engine is running, the gage shows the
condition of the charging system. Readings between the
low and high warning zones indicate the normal
operating range. Readings in
the low warning zone may occur when a
large number
of electrical accessories are operating in
the vehicle and the engine is left at an idle for
an
extended period. This condition is normal since the
charging system
is not able to provide full power at
engine idle.
As engine speeds are increased, this
condition should correct itself as higher engine speeds
allow
the charging system to create maximum power.
You
can only drive for a short time with the reading in
either warning zone. If you must drive, turn off all
unnecessary accessories.
Readings in either warning zone indicate a possible
problem in the electrical system. Have the vehicle
serviced as soon as possible.

With the anti-lock brake system, this light will come on
when you start your engine and may stay on for several
seconds. That’s normal.
If the light stays
on, or comes on when you’re driving,
your vehicle needs service. If the regular brake system
warning light isn’t
on, you still have brakes, but you
don’t have anti-lock brakes. If the regular brake system
warning light is also on, you don’t have anti-lock brakes
and there’s a problem with your regular brakes. See
“Brake System Warning Light” earlier in this section.
The anti-lock brake system warning light should come
on briefly 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.

This gage shows the engine
coolant temperature. If the
gage pointer moves into
the red area your engine is
too hot!
It means that your engine coolant has overheated. If
you have been operating your vehicle under normal
operating conditions,
you should pull off the road, stop
your vehicle, and turn
off the ‘engine as soon as possible.

with a computer which
monitors operation
of the
fuel, ignition and emission
control systems.
This system is called OBD I1 (On-Board
Diagnostics-Second Generation) and
is intended to
assure that emissions
are at acceptable levels for the life
of the vehicle, helping
to produce a cleaner
environment. The
SERVICE ENGINE SOON light
comes on to indicate that there
is a problem and service
is required. Malfunctions often will be indicated by the
system before any problem is apparent. This may
prevent more serious damage to your vehicle. This
system
is also designed to assist your service technician
in correctly diagnosing any malfunction.
NOTICE:
If you keep driving your vehicle with this light
on, after a while, your emission controls may not
work as well, your fuel economy may not be
as
good and your engine may not run as smoothly.
This could lead
to costly repairs that may not be
covered by your warranty.
This light should come on, as a check to show you it is
working, when
the ignition is on and the engine is not
running. If the light doesn’t come on, have it repaired.
This light
will also come on during a malfunction in one
of two ways:
0
0
Light Flashing -- A misfire condition has been
detected.
A misfire increases vehicle emissions and
may damage the emission control system
on your
vehicle.
GM or qualified service center diagnosis
and service may be required.
Light On Steady -- An emission control system
malfunction has been detected on your vehicle.
GM
or qualified service center diagnosis and service may
be required.
