Fuel Gage
... 100
Your fuel page shows about how much
fuel
is in your tank. The fuel gage works
only when the ignition switch is
in the
Run position. When the gage pointer first
indicates
E, you still have a little fuel left
(about one to two gallons),
but you need
to get more right away. Here
are four concerns some owners
have had about the fuel gage.
All these
e
situations are normal and do not indicate
that anything
is wrong with the fuel gage.

At the gas station, the gas pump shuts
off before the gage reads
F.
It takes more (or less) gas to fill up
than the gage reads. For example, the
gage reads
1/2 full, but it took more
(or
less) than half of the tank's
capacity
to fill it.
The gage moves a little when you
turn, stop or speed up.
When you
turn the engine off, the
c gage doesn't go back to E.
Brake System Warning Light
Your Chevrolet'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 goes on, there could
be a brake problem. Have your brake
system inspected right away.
This light should come on as you start the
vehicle.
If it doesn't come on then, have it
fixed so it will be ready to warn you if
there's a problem.

them to overheat to the point
that they won’t work well. You
might
not be able to stop your
vehicle
in time to avoid an accident.
If you “ride” your brakes, they
will
get so hot they will require a lot of
pedal force to slow you down.
Avoid “riding” the brakes. Klamg-.

lnuch faster. You would need costly
brake replacement much sooner
than normal, and
it also reduces fuel
economy.
If you keep pace
with the traffic and
allow realistic following distances, you
will eliminate a lot of unnecessary
braking. That means better braking and
longer brake life.
I
If your engine ever stops while you’re
driving, brake normally
but don’t
pump your brakes. If you do,
the
pedal may get harder to push down. If
your engine stops, you
will still have
some power brake assist.
But you will
use it when you brake. Once the
power assist is used up, it may take
longer to stop and the brake pedal
will
be harder to push.

NOTICE:
Fuel
The 8th digit of your Vehicle
Identification Number (VIN) shows
the code letter for your engine.
You will
find the VIN at the top left
of your
instrument panel. (See “Vehicle
Identification Number” in the Index.)
3.4L L32 (Code S)
Use regular unleaded gasoline rated at
87 octane or higher. It should meet
specifications ASTM
D4814 in the U.S.
and CGSB 3.5-92 in Canada. These fuels
should have the proper additives,
so you
should not have to add anything to the
fuel.
In the U.S. and Canada, it’s easy to
be
sure you get the right kind of gasoline
(unleaded). You’ll see
UNLEADED right
In the pump. And only unleaded nozzles
will
fit into your vehicle’s filler neck.
Be sure the posted octane is at least 87.
:f the octane is less than 87, you may get
sl heavy knocking noise when you drive.
If it’s bad enough, it can damage your
engine.
If you’re using fuel rated at
87 octane or
higher and you still hear heavy knocking,
your engine needs service. But don’t
worry if you hear a little pinging noise
when you’re accelerating or driving up a
hill. That’s normal, and you don’t have to
buy a higher octane fuel to get rid of
pinging. It’s the heavy, constant knock
that means you have a problem.

5.7L LT1 (Code P)
Use premium unleaded gasoline rated at
91 octane or higher. You may use middle
grade
or regular unleaded gasolines, but
your vehicle may not accelerate as well.
The gasoline you use should meet
specifications ASTM
D48 14 in the U.S.
and CGSB 3.5-92 in Canada. These fuels should have the proper additives,
so you
should not have to add anything to the
fuel.

(unleaded). You’ll see
UNLEADED right
on the pump. And only unleaded nozzles
will fit into your vehicle’s filler neck. Be
sure
the posted octane for premium is
at least 91 (at least
89 for middle grade
and
87 for regular). If the octane is less
than
87, you may get a heavy knocking
noise when you drive. If it’s bad enough,
it can damage your engine.
If you’re using fuel rated at 91 octane or
higher and you still hear heavy knocking,

All Engines
What about gasoline with blending
materials that contain oxygen, such as
MTBE
or alcohol?
MTBE is “methyl tertiary-butyl ether.”
Fuel that is no more than 15% MTBE is
fine for your vehicle.
Ethanol is ethyl or grain alcohol.
Properly-blended fuel that is no more
than 10%
ethanol is fine for your vehicle.

Circuit breakers protect the power
windows and other power accessories.
When the current load is
too heavy, the
circuit breaker opens and closes,
protecting the circuit
until the problem is
fixed or goes away.
