(Service Engine Soon Light)
SERVICE
ENGINE
SOON
NOTICE:
If you keep driving your vehicle with this light
on, after
a while, your emission controls may not
work as well, your fuel econonly 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 ;I check to show you it is
working, tvhen the ignition is on and the engine is not
running. It' the light doesn't conw on, have it repaired.
This light will also come on during a malfunction in one
of two t1;ays:
2-77

Some gasolines that are not reformulated for low
emissions contain an octane-enhancing additive called
methylcyclopentadienyl manganese tricarbonyl
(MMT):
ask your service station operator whether or not his fuel
contains MMT. General Motors does not recommend the
use
of such gasolines. If fuels containing MMT are used,
spark plug life may be reduced and your emission
control system performance
may be affected. The
malfunction indicator lamp on your instrument panel
may turn on.
If this occurs, return to your authorized
GM dealer for service.
To provide cleaner ail-, all gasolines in the United States
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.
I 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.
Fuels in Foreign Countries
If you plan on driving in another country outside the United
States or Canada, the proper fuel may be hard to find. Never
use leaded gnsooline or any other fuel not recommended
in the
previous text on fuel. Costly repairs caused by use of
improper fuel wouldn’t be covered by your warranty.
To check on ~w1 availability, ask an auto club, or
contact a nlajor oil company that does business in the
country where you’ll be driving.
You can also write us at the following address for
advice. Just tell us where you-re going and give your
Vehicle Identil’ication Number
(VIN).

Brake Wear
Your vehicle has front disc brakes and rear drum brakes.
If you have the all-wheel drive option, your vehicle has
four-wheel disc 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 A CAUTION: I
The brake wear warning sound means that soon
your brakes won't
work well. That could lead to
an accident. When you hear the brake wear
warning
sound, have your vehicle serviced.
NOTICE:
Continuing to drive with worn-out brake pads
could result in costly brake repair.
Some driving conditions or climates may cause a brake
squeal when the brakes are first applied or lightly
applied. This does not mean something is wrong
with
your brakes.
Properly torqued wheel nuts are necessary to help
prevent brake pulsation. When tires are rotated, inspect
brake
pads for wear and evenly torque wheel nuts in the
proper sequence to
GM specifications.
Your rear
drum brakes don't have wear indicators,
but
if you ever hear a rear brake rubbing noise: have
the rear brake linings inspected. Also, the rear brake
drums should be removed and inspected each time the
tires are removed
for rotation or changing. When you
have the front brake pads replaced. have the rear brakes
inspected, too.
Brake linings should always be replaced as complete
axle sets.
See
"Brake System Inspection" in Section 7 of this manual
under
Part C "Periodic Maintenance Inspections."

When It's Time for New Tires
One way to tell when it's
time for new tires is to
check the treadwear
indicators, which will
appear
when YOLII- tires have
only 1/16 inch ( I .6 mm) or
less
of tread remaining.
You need a new tire if any of the following statements
are true:
0 You can see the indicators at three or more places
around the tire.
You can see cord or hbric showing through the
tire's rubber.
The tread or sidewall is cracked. cut or snagged deep
enough
to show cord or fabric.
The tire has a bump. bulge or split.
The tire has a puncture, cut or other damage that
can't be repaired well because of the size or location
of the darnage.
Buying New Tires
To find out what kind ;m.l size of tires you need, look at
the CertificatiodTire label.
The tires installed on your vehicle when
it was new had
a Tire Performance Criteria Specification (TPC Spec)
number
on each tire's sidewall. When you get new tires,
your vehicle
will continue to have tires that are designed
to give proper endurance, handling, speed rating,
traction. ride and other things during normal service
on
your vehicle. If your tires have an all-season tread
design, the
TPC number will be followed by an "MS"
(for mud and snow).
If you ever replace your tires with those not hktving a
TPC Spec number. make sure [hey are the same size.
load range, speed rating and construction type (bias,
bias-belted or radial) as your original tires.
c get ones with that same TPC Spec number. That way
