Warning Lights, Gages and Indicators
This part describes the warning lights and,gages that
may be
on your vehicle. The pictures will help you
locate them.
Warning lights and gages can signal that something
is
wrong before it becomFs serious enough to cause an
expensive repair or replacement. Paying attention to
your warning.lights and gages could also save you or
others from injury.
Warning lights come on when there may be or is a
problem with one of your vehicle’s functions.
As you
will see in the details on the next few pages, some
warning lights come on briefly when you start the
engine just to let you know they’re working.
If you are
‘familiar with this section, you should not be alarmed
when this happens.
Gages can indicate when there may be or is a problem
with one-of your vehicle’s functions. Often gages and
warning lights work together to let you know when
there’s a problem with your vehicle.
When one
of the warning lights comes on and stays on
when you are driving, or when one of the gages shows
there may be a problem, check the section that
tells you
what to do about
it. Please follow this manual’s advice.
Waiting to do repairs can be costly
-- and even dangerous.
So please
get to know your warning lights
and gages. They’re
a big help.
Fuel Gage
Your fuel gage tells you
about how much fuel
YOU
have left when the ignition
is on. When the indicator
nears
EMPTY (E), you still
have
a little fuel left, but
you should get more soon.
UNLEADED FUEL ONLY I

Here are some things owners ask about. All these
situations are normal and do not show a problem with
your fuel gage:
0 At the service station, the pump shuts off before the
gage reads
FULL (F).
0 . It takes a little more or less fuel to fill up than the gage
indicated. For example, the gage may have indicated
the
tank was half full, but it actually took a little more
or less
than half the tank‘s capacity to fill it.
The gage moves a little when you turn a corner or
speed up.

Fuel
Use regular unleaded gasoline rated at 87 octane or
higher. It should meet specifications ASTM
D4814 in
the United States 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 United States and Canada, it’s easy to be sure you
get the right kind of gasoline (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.is at least 87.
If the octane is
less than 87, you may get a heavy knogking 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.

What about gasoline with blending materials that
contain oxygen (oxygenates), 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
vehcle.
Methanol is methyl or wood alcohol.
NOTICE:
Fuel that is more than 5% methanol is bad for
your vehicle. DonTt use it. It can corrode metal
parts in your fuel system and also damage plastic
and rubber parts. That damage wouldn’t b,e
, covered under your warranty. And even at 5% or
less,, there must be “cosolvents”
and corrosion
preventers in
this fuel to help avoid these
problems.
