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 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 Car” in the Index.)
1 &!A CAUTION:
Your brake system may not be working properly
if the brake warning light is on. Rriving with the
brake 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.
Anti-Lock Brake System Warning Light
1-
ANTI
LOCK
With anti-lock, this light will go on when you start your
engine and may stay on for several seconds or
so. That’s
normal. If the light doesn’t come on, have it fixed
so it
will be ready to warn you if there is a problem.
If the light stays on or comes
on when you’re driving,
stop as soon as possible and turn the key off. Then start
the engine
to reset the system. If the light still stays on,
or comes
on again while you’re driving, your Buick
needs service. Unless
the regular brake system warning
light is also
on, you will still have brakes, but not
anti-lock brakes. If the regular brake system warning
light
is also on, see “Brake System Warning Light”
earlier
in this part.

this happens, the light means you won’t have anti-lock
until you replace the compact spare with a full-size tire.
If the warning light stays on after you replace the
compact spare with a full-size tire, or
if it comes on
again when you’re driving, your Buick needs service.
TRACTION
OFF
The “TRACTION OFF”
warning light means that
the system is not working.
This warning light may
come on for the following
reasons:
0 If your transaxle overheats, the traction control
system automatically shuts
off for about three
minutes. The warning light will come on and stay on
during that time.
.
0 If your brakes overheat, the traction control system
will
go off and the warning light will come on until
your brakes cool down.
If the “TRACTION
OFF” warning light comes on and
stays on for an extended period
of time, your vehicle
needs service.

Engine Coolant Temperature Gage
If you have the Gage Cluster, you have a gage that
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, stop your
vehicle and turn off
the engine as soon as possible.
HOT COOLANT CAN BURN YOU BADLY!
In “Problems on the Road,” this manual shows what to
do. See “Engine Overheating”
in the Index.

‘‘Check Oil Level” Light (Option)
CHECK
OIL LEVEL.,
The “Check Oil Level”
light is lit for three seconds
as a bulb check each time
the ignition key is turned to
the RUN position.
If
the light doesn’t come on, have your vehicle serviced.
If the engine
oil is more than one quart low, the light
will come
on briefly, then go off for 15 - 25 seconds,
and then come back
on for 20 - 40 seconds.
However,
if it has not been more than eight minutes
since the engine was
shut off, the system will not
register a low engine oil condition.
If the “Check Oil Level” light comes back on, the
engine oil should be checked at the dipstick and then
brought up
to the proper level if necessary. See
“Engine Oil”
in the Index.

“Change Oil Soon’’ Light (Option)
This light is activated by
the Engine Oil Life
Monitor System. It
indicates that the engine oil
has degraded enough to
require changing. See
“Engine Oil”
in the Index.
After changing the engine oil, the system should be
reset.
This will cause the “Change Oil Soon” light once
again, to be lit for just
the bulb check period of 3
seconds.
This
is determined by electronically monitoring engine
speed, coolant temperature and vehicle speed. Since the
change interval is dependent on driving habits and
conditions, the “Change Oil Soon” light may come on as
early as
2,000 miles or less for harsh circumstances.
The “Change Oil Soon” light is lit for three seconds as a
bulb check each time the ignition key is turned to
the
RUN position. If an oil change is required, it will stay
on for 60 seconds each time the engine is started. If the
“Change Oil Soon” light is on continuously, there is a
problem with the Oil Life Monitor System and service
is
required. The reset button
is inside this hole, which is under the
passenger’s side of the instrument panel, near the door.
With the ignition key in
the RUN position, but the
engine not started, use a pen
to push the reset button,
holding
it in for at least 5 seconds but not more than 60
seconds. After 5 seconds, the “Change Oil Soon” light
will flash
4 times and then turn off. This indicates that
the Oil Life Monitor System has been reset.

Traction Control System (Option)
Your vehicle may have a traction control system that
limits wheel spin. This is especially
useful in slippery
road conditions. The traction control system works at
low speeds only, such
as when you accelerate from a
stop. It applies brake pressure
to an individual wheel
that the system senses is about to spin.
You may feel the system working, or
you may notice
some noise, but this is normal.
OFF
The “TRACTION OFF” warning light lets you know if
your traction control system is not working. See
“Traction Control System Warning Light” in the Index.
Disc Brake Wear Indicators
Your Buick has front disc brakes and rear drum brakes.
Disc brake pads have built-in wear indicators that make a
high-pitched warning sound when the brake pads are
worn and new pads are needed. The sound may come and
go or be heard all the time your vehicle is moving (except
when you are pushing
on the brake pedal firmly).
A CAUTION:
0
The brake wear warning sound means that
sooner or later your brakes won’t work well. That
could lead to an accident. When you hear the
brake wear warning sound, have your vehicle
serviced.
Some driving conditions or climates may cause a brake
squeal when the brakes are first applied or lightly
