Safety Belt Warning 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.
/r CAUTION:
-
1 urour safety belt light ever comes on or stays on
after the front doors are closed and the driver’s
belt is buckled, have your vehicle fixed.
If you don’t, the belt might not work as it should,
and
you might not have the protection you’d
need in a crash.
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 module,
the wiring and the diagnostic module.
For more
information
on the air bag system, see “Air Bag” in
the Index.
AIR
BAG
You will see this light flash
for a few seconds when you
turn your ignition
to RUN
or START. Then the light
should go out. This means
the system is ready.
If the air bag readiness light doesn’t come on when you
start your vehicle, or stays on, or comes on when you
are driving, your air bag system may not work properly.
Have your vehicle serviced right away.

Battery Light
I-+I
The battery warning light is
designed to come on briefly
when you turn on the
ignition, but the engine is
not running, as
a check to
show you it is working.
Then it should go out.
If it stays on, or comes on while
you
are driving, you may have a problem with the
electrical charging system. It could indicate that you
have a loose generator 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.
Brake System Warning Light
Your Buick’s hydraulic brake system is divided into two
parts.
If one part isn’t working, the other part can still
work and stop you. For good braking, though, you need
both parts working well.
If the warning light comes on, there could be a brake
problem. Have your brake system inspected right
away.
BRAKE
This light should come on
briefly when you turn the
ignition key to
RUN. If
it doesn’t come on then,
have it fixed
so it will be
ready to warn you if there’s
a problem.
If the light comes on while you
are driving, 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.
If the light is still on, or if the
anti-lock brake system warning light is flashing, have the
vehicle towed for service.
(See “Anti-Lock Brake System
Warning Light” and ‘Towing Your Vehicle” in the Index.)

A CAUTION:
--
Your brake system may not be working properly
if the brake system warning light is on. Driving
with the brake system warning light on can lead
to an accident.
If the light is still on or if the
anti-lock brake system warning light
is flashing
after you’ve pulled off the road and stopped
carefully, have the vehicle towed for service.
When the ignition is on, the brake system warning light
will also come
on when you set your parking brake. The
light will stay
on if your parking brake doesn’t release
fully.
If it stays on after your parking brake is fully
released, it means you have
a brake problem.
Anti-Lock Brake System Warning Light

LOCK
Domestic
~~
Canadian
With the anti-lock brake system, one of these lights will
come on when you start your engine and will stay
on for
three seconds. That’s normal.

ProCarManuals.com

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.
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.

Engine Coolant Temperature Gage
II k
TEMPERATURE -Z
Domestic Canadian
This
gage shows the engine coolant temperature. If the gage
pointer moves into the red area, your engine is too hot!
That reading means the same thing
as the warning light.
It means that your engine coolant has overheated. If you
have been operating your vehicle under normal driving
conditions, you should pull off the road, and stop your
engine as soon as possible.
The section “Problems on the Road,” in this manual
explains what to do. See “Engine Overheating” in
the Index.
Malfunction.Indicator Lamp
(Service Engine Soon Light)
SERVICE
ENGINE
SOON
Domestic Canadian
Your
Buick is equipped with a computer which
monitors operation
of the fuel, ignition and emission
control systems.
2-54
ProCarManuals.com

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 to
indicate that there is a problem and service is required.
Malfunctions often will be indicated by the system
before any problem
is apparent, which 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. Dealer or qualified service center diagnosis
and service is required.
Light On Steady -- An emission control system
malfunction has been detected on your vehicle.
Dealer or qualified service center diagnosis and service may be required.

If the Light Is Flashing If the Light Is On Steady
The following may prevent more serious damage to
your vehicle:
Reduce vehicle speed.
Avoid hard accelerations.
Avoid steep uphill grades.
If towing a trailer, reduce the amount of cargo being
hauled as soon
as it is possible.
If the light stops flashing and remains on steady, see
“If
the Light Is On Steady” following.
If the light continues to flash, when it is safe to do
so,
stop the vehicle. Put your vehicle in PARK (P). Turn the
key off, wait at least
10 seconds and restart the engine.
If the light remains on steady, see “If the Light
Is On
Steady” following. If the light
is still flashing follow the
previous steps, and drive the vehicle
to your dealer or
qualified service center for service. You
may be able to correct the emission system
malfunction by considering the following:
Did you just put fuel into your vehicle?
If
so, reinstall the fuel cap, making sure to fully install
the cap. The diagnostic system can determine if the fuel
cap has been left off or improperly installed. This will
allow fuel to evaporate into the atmosphere. A few
driving trips should turn the light off.
Did you just drive through a deep puddle
of water?
If
so, your electrical system may be wet. The condition
will usually be corrected when the electrical system
dries out. A few driving trips should turn the light
off.
Are you low on fuel?
As your engine starts to run out of fuel, your engine may
not run as efficiently
as designed since small amounts of
air are sucked into the
fuel line causing a misfire. The
system can detect this. Adding fuel should correct this
condition. Make sure to install the fuel
cap properly. It
will take a few driving trips to turn the light off.
ProCarManuals.com

Have you recently changed brands of fuel?
If
so, be sure to fuel your vehicle with quality fuel (see
“Fuel” in the Index). Poor fuel quality will cause your
engine not to run as efficiently as designed. You may
notice this as stalling after start-up, stalling when you
put the vehicle into gear, misfiring, hesitation on
acceleration or stumbling on acceleration. (These
conditions may go away once the engine is warmed up.)
This will be detected by the system and cause
the light
to turn on.
If
you experience this condition, change the fuel brand
you
use. It will require at least one full tank of the
proper fuel
to turn the light off.
If none of the above steps have made the light turn off,
have your dealer or qualified service center check the
vehicle. Your dealer has the proper
test equipment and
diagnostic tools to
fix any mechanical or electrical
problems that may have developed.
Engine Oil Pressure Light
If you have a problem with
your oil, this oil pressure
warning light may stay
on
after you start your engine,
or come
on when you are
driving. Stop your vehicle
and shut
off the engine if
this light stays on.
This indicates that oil is
not going through your
engine quickly enough
to keep it lubricated.
The engine could be low on oil, or could have
some other oil problem. Have your vehicle
serviced immediately.
