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
when you turn the 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.
I I
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 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 you try to drive off with the
parking brake set, a chime will also come on until you
release the parking brake.
If the light and chime stay on
after your parking brake
is fully released, it means you
have a brake problem.
If the light and chime come 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, have the vehicle towed for service. (See “Towing
Your Vehicle” in the Index.)

Anti-Lock Brake System Warning Light
With the anti-lock brake
system, the light(s) will
come on when you start
your engine and may stay
on for several seconds.
That’s normal.
If the light stays on and the chime sounds, turn the
ignition to
OFF. Or, if the light comes on and the chime
sounds 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 and the chime
sounds, or the light comes on again while you’re
driving, your Buick 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.
Traction Control System Warning Light
(Option)
TRAC
OFF
This warning light should
come
on briefly as you start
the engine. If the warning
light doesn’t come
on then,
have it fixed
so it will be
ready to warn you if there’s
a problem.
If it stays on, or comes on when you’re driving, there
may be a problem with your traction control system and
your vehicle may need service. When this warning light
is on, the system will not limit wheel spin. Adjust your
driving accordingly.

e
0
e
If you turn the system off by pressing the button
located on the end of the shift lever, the warning
light will come on and stay on. To turn the system
back on, press the button again. The warning light
should go
off. (See “Traction Control System” in
the Index for more information.)
If there’s a brake system problem that
is specifically
related
to traction control, the traction control system
will turn
off, the warning light will come on and the
chime will sound.
If the traction control system is affected by an
engine related problem, the system will turn off,
the warning light will come on and the chime
will sound.
If the traction control system warning light comes on
and stays on for an extended period
of time when the
system
is turned on, your vehicle needs service.
Engine Coolant Temperature Gage
TEMPERATURE
This gage measures the
temperature of your engine.
If the pointer moves into the
red area, your engine is too
hot.
A temperature indicator
light will turn on and a
chime will sound.
If you have been operating your vehicle under normal
driving conditions and the temperature indicator light
turns on, you should pull off the road, stop your vehicle
and turn off the 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
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.
1 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 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.
0 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.
ProCarManuals.com

If’ the Light Is Flashing
The following may prevent more serious damage to
your vehicle:
e Reducing vehicle speed.
e 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 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 Pressure Light
OIL
This light tells you if there
could be a problem with
your engine oil pressure.
There are three ways the oil pressure light can come on
briefly, which are normal and don’t show a problem.
They are:
The light comes on when you turn your key to RUN.
It goes off once you turn the key to START. That’s
just a check to be sure the light works. If
it doesn’t,
be sure to have
it fixed so it will be there to warn you
if something goes wrong.
If you’re “idling” at a stop sign, the light may blink
on and then off.
If you make a hard stop, the light may come on
for a moment.
When this light comes on and stays on, and a chime
sounds, it means oil isn’t
going through your engine
properly. You could
be low on oil, or you might have
some other oil problem. See your dealer for service.
Don’t keep driving if the oil pressure is
low. If
you do, your engine can become so hot that it
catches fire. You or others could be burned.
Check your oil as soon as possible and have your
vehicle serviced.
I NOTICE:
Damage to your engine from neglected oil
problems can be costly and
is not covered by
your warranty.

Service Vehicle Soon Light
SERVICE
VEHICLE SOON
This light will come on if
you have certain
non-emission related
vehicle problems.
I
These problems may not be obvious and may affect
vehicle performance or durability. Consult a qualified
Buick dealership for necessary repairs to maintain top
vehicle performance. The light will come on briefly
when your ignition is turned on to show that it is
working properly.
Fuel Gage
UNLEADED FUEL ONLY
Your fuel gage shows
about how much fuel is in
your tank.
It works only when the ignition is on. When the
indicator moves to the edge of the low fuel warning
band, the low fuel light will turn on and a chime will
sound. You still have a little fuel left, but you need to get
more fuel right away.
A concern owners have had about the fuel gage is that it
takes more (or less) gas to fill up than the gage indicated.
For example, the gage may have indicated
half full, but it took more
(or less) than half of the tank's
capacity to fill it. This situation is normal and indicates
nothing wrong with the fuel gage.

Care of Your Cassette Tape Player
A tape player that is not cleaned regularly can cause
reduced sound quality, ruined cassettes or a damaged
mechanism. Cassette tapes should be stored in their
cases away from contaminants, direct sunlight and
extreme heat. If they aren’t, they may not operate
properly or may cause failure of the tape player.
Your tape player should be cleaned regul-arly after every
50 hours of use. Your radio may display CLN to indicate
that you have used your tape player for
50 hours without
resetting the tape clean timer. If this message appears
on the display, your cassette tape player needs to be
cleaned. It will still play tapes, but you should clean it as
soon as possible
to prevent damage to your tapes and
player. If you notice a reduction in sound quality, try a
known good cassette to see if it is the tape or the tape
player at fault. If this other cassette has no improvement
in sound quality, clean the tape player. Cleaning
may be done with a scrubbing action,
non-abrasive cleaning cassette with pads which scrub
the tape head as the hubs of the cleaner cassette turn.
A scrubbing action cleaning cassette is available through
your Buick dealership.
You may also choose a non-scrubbing action, wet-type
cleaner which uses a cassette with a fabric belt to clean
the tape head. This type of cleaning cassette may not
clean as thoroughly as the scrubbing type cleaner.
After you clean the player, press and hold EJECT for
five seconds to reset the CLN indicator. The radio will
display
--- to show the indicator was reset.
Cassettes
are subject to wear and the sound quality
may degrade over time. Always make sure the cassette
tape is in good condition before you have your tape
player serviced.

Once you are moving on the freeway, make certain you
allow a reasonable following distance. Expect to move
slightly slower at night.
When you want to leave the freeway, move to the proper
lane well in advance. If you miss your exit, do not,
under any circumstances, stop and back up. Drive on to
the next exit.
The exit ramp can be curved, sometimes quite sharply.
The exit speed is usually posted.
Reduce your speed according to your speedometer, not
to your sense of motion. After driving for any distance
at higher speeds, you may tend to think you
are going
slower than you actually are.
Before Leaving on a Long Trip
Make sure you’re ready. Try to be well rested. If you
must start when you’re not fresh
-- such as after a day’s
work
-- don’t plan to make too many miles that first part
of the journey. Wear comfortable clothing and shoes you
can easily drive in. Is
your vehicle ready for a long trip? If you keep it
serviced and maintained, it’s ready to go. If it needs
service, have it done before starting out. Of course,
you’ll find experienced and able service experts in
Buick dealerships all across North America. They’ll be
ready and willing to help if you need it.
Here are some things you can check before a trip:

Tires: They are vitally important to a safe,
trouble-free trip. Is the tread good enough for
long-distance driving? Are the tires all inflated to the
recommended pressure?
Weather Forecasts: What’s the weather outlook
along your route? Should you delay your trip a short
time to avoid a major storm system?
Maps: Do you have up-to-date maps?
