If your vehicle seems to start up rather slowly, or
if it seems not to shift gears as you go faster,
something may be wrong with a transaxle system
sensor.
If you drive very far that way, your
vehicle can be damaged.
So, if this happens, have
your vehicle serviced right away. Until then, you
can use

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.
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

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.

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

Malfunction Indicator Lamp
(Service Engine Soon Light)
Your Buick is equipped
with a computer which
monitors operation
of the
fuel, ignition and emission
SERVICE ENGINE control systems.
SOON
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.
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:
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
The following may prevent more serious damage to
your vehicle:
0 Reducing vehicle speed.
0 Avoiding hard accelerations.
0 Avoiding steep uphill grades.
0 If you are 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. Find a safe place to park your vehicle.
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.
If the Light Is On Steady
You may be able to correct the emission system
malfunction by considering the following:
Did you recently 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. A loose or
missing fuel cap will allow fuel to evaporate into the
atmosphere.
A few driving trips with the cap properly
installed 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.

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 one or more of these conditions,
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.
Oil Warning Light
If you have a problem with
your oil, this light may stay
on after you start your
engine, or come on when
you are driving.
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 it fixed right away.
The oil light could also come on in the
following situations:
The light will come on briefly when you turn on the
ignition to show
you that it is working properly. (If it
doesn’t come
on with the ignition on, you may have
a problem with the fuse or bulb. Have it fixed
right away.)
Sometimes when the engine is idling at a stop, the
light may blink on and off. This is normal.
