1996 GMC SAVANA service indicator

Anti-Lock Rrake System Warning Light
ANTI -
LOCK
United States
Canada
With the anti-l,dck 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, 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 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.

Malfunction Indicator Lamp (Service Engine Soon Light) (Gasoline Engine)
Your vehicle is equipped
with a computer which
monitors operation of the
-
SERVICE
ENGINE SOON
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. 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 your vehicle is certified to meet California Emission
Standards (inciicatecl 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
Y~LII' instrument panel may turn on and/or your vehicle
may fail a smog-check test.
If this OCCLII-S, return to YOLK
authorized GM dealer for diagnosis to determine the
cause of failure.
In the event it is cletermined that the
ca~~se
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 crdled MMT.
IF you LIS~ such f~~els. your
emission control system performance may deteriorate
and the malfunction indicator lamp on your instrument
panel may turn on.
If this happens, return to YOLII'
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 reforn~~lated gasolines may
be
available in your area to help clean the air. General
Motors recmnlnends that you use these gasolines ilthey
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.

Brake Wear
NOTICE:
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.
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).
L
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: I
Continuing to drive with worn-out brake pads
could result
in costly brake repair.
