Warning Lights, Gages
and Indicators
This part describes the warning lights and gages that
may be on your vehicle. The pictures will help you
locate them.
Warning lights and gages can signal that something is
wrong before it becomes serious enough
to cause an
expensive repair or replacement. Paying attention to
your warning lights and gages could also save
you or
others from injury.
Warning lights come on when there may be or is a
problem with one of your vehicle’s functions.
As you
will see in the details on the next few pages, some
warning lights come
on briefly when you start the
engine just to let you know they’re working. If you are
familiar with this section,
you should not be alarmed
when this happens.
Gages can indicate when there may be or is a problem
with one of your vehicle’s functions. Often gages and
warning lights work together
to let you know when
there’s a problem with your vehicle.
When one of the warning lights comes on and stays on
when
you are driving, or when one of the gages shows
there may be a problem, check the section that tells
you
what to do about it. Please follow this manual’s advice.
Waiting to
do repairs can be costly -- and even
dangerous.
So please get to know your warning lights
and gages. They’re a big help.
Your vehicle may also have a driver information system
that works along with the warning lights and gages. See
“Driver Information System’’ in the Index.
Safety Belt Reminder Light
When the key is turned to RUN or START, a chime will
come on for about eight seconds to remind people to
fasten their safety belts, unless the driver’s safety belt is
already buckled.
The safety belt light will
also come on and stay on
for about
20 seconds, then
it will flash for about
55 seconds. If the driver’s
belt is already buckled,
neither the chime nor the
light will come on.

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 modules, the
wiring and the crash sensing and diagnostic module. For
more information on the air bag system, see “Air Bag”
in the Index.
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
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 should
1+1 go out.
##
If it stavgdn, or comes on while you are driving, you
may b&e
a problem with the charging system. It could
inqk6ate that you have
a loose drive belt or another
dectrical 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.

Anti-Lock Brake System Warning Light
ANTI -
LOCK
With the anti-lock brake
system, this light will
come
on when you start
your engine and it will
stay on for three seconds.
That’s normal.
If the light flashes when you’re driving, you don’t have
anti-lock brakes and there could be a problem with your
regular brakes. Pull off the road and stop carefully.
You
may notice that the pedal is harder to push. Or, the pedal
may go closer to the floor.
It may take longer to stop.
Have the vehicle towed for service. (See “Towing Your
Vehicle” in the Index.)
Your regular brake system may not be working
properly if the anti-lock brake system warning
light is flashing. Driving with the anti-lock
brake system warning light flashing can lead
to an accident. After you’ve pulled off the road
and stopped carefully, have the vehicle towed
for service.
I
If the anti-lock brake system warning light stays on
longer than normal after you’ve started your engine, turn
the ignition off. Or, if the light comes on and stays on
when you’re driving, stop as soon as possible and turn
the ignition off. Then start the engine again to reset the
system. If the light still stays on, or comes on again
while you’re driving, your Buick needs service. If the
light
is on but not flashing and the regular brake system
warning light isn’t on, you still have brakes, but you
don’t have anti-lock brakes.
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.

Malfunction Indicator Lamp (Service Engine Soon Eight)
SERVICE ENGINE
SOON
Your Buick is equipped
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. (In Canada,
OBD I1 is replaced by
Enhanced Diagnostics.) The
SERVICE ENGINE
SOON light comes on and a chime will sound 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.
