ANTI -
LOCK
United States
Canada
With the anti-lock brake system, this light will come on
when you start your engine and may stay
on for several
seconds. That’s normal.
If the light stays on, or comes on when you’re driving,
your vehicle needs service.
If the regular brake system
warning light isn’t
on, y0~1’still have brakes, but YOLI
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 part. 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.
Daytime Running Lamps Indicator Light
You may have this light on
the instrument panel. It will
light whenever the DRL are
on.
It is also a reminder to
turn on your headlamps
when driving at night. For
more details about
DRL, see
“Headlamps and Vehicle
Lighting”
in this section.

Engine Soon Light) (Gasoline Engine)
Your vehicle is equipped
with a computer which
monitors operation of the
fuel, ignition and emission
control systems.
SERVICE
ENGINE 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. 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.
I 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.
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.

Downloaded from www.Manualslib.com manuals search engine If your vehicle is certified to meet California Emission
Standards (indicated on the underhood tune-up label),
it
is designed to operate on fuels that meet California
specifications.
If such fuels are not available in states
adopting California emissions standards, your vehicle
will operate satisfactorily on fuels meeting federal
specifications, but emission control system performance
may be affected. The malfunction indicator lamp
on
your instrument panel may turn on and/or your vehicle
may fail a smog-check test.
If this occurs, return to your
authorized GM dealer for diagnosis to determine the
cause
of hilure. In the event it is determined that the
cause
of the condition is the type of fuels used, repairs
may
not be covered by your warranty.
In Canada, some gasolines contain an octane-enhancing
additive called
MMT. If you use such fuels, your
emission control system performance may deteriorate
and the malfunction indicator lamp
on your instrument
panel
may turn on. If this happens, return to your
authorized GM dealer for service.
To provide cleaner air, all gasolines are now required to
contain additives that will help prevent deposits from
forming
in your engine and fuel system, allowing your
emission control system to function properly. Therefore,
you should
not have to add anything to the fuel. In
addition, gasolines containing oxygenates, such as ethers
and ethanol, and reformulated gasolines may be
available
in your area to help clean the air. General
Motors recommends that
you use these gasolines if they
comply with the specifications described earlier.
NOTICE:
Your vehicle was not designed for fuel that
contains methanol. Don’t use it.
It can corrode
metal parts in your fuel system and also damage
plastic and rubber parts. That damage wouldn’t
be covered under your warranty.

a
0
Using the wrong fluid can badly damage
brake system parts. For example, just a few
drops of mineral-based oil, such as engine
oil,
in your brake system can damage brake
system parts
so badly that they’ll have to be
replaced. Don’t let someone put in the
wrong kind of fluid.
If you spill brake fluid on your vehicle’s
painted surfaces, the paint finish can be
damaged. Be careful not to spill brake fluid
on your vehicle.
If you do, wash it off
immediately. See “Appearance Care” in
the Index.
Brake Wear
Your vehicle 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).
I
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.
I NOTICE:
Continuing to drive with worn-out brake pads
could result in costly brake repair.
