Fuel Gage
Your fuel gage tells you about how much fuel you have
left, when the ignition is on. When the indicator nears
“E” (Empty), you still have a little fuel left, but you
should get more
soon.
Here are four things that some owners ask about. None
of these show a problem with your fuel gage and are
normal operating characteristics:
At the service station, the gas pump shuts off before the
gage reads
“F” (Full).
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 the tank.
The gage moves a little when you turn a corner, speed
up or brake.
The gage doesn’t go back to “E” when you turn off the
ignition.
Engine Oil Pressure Light
If you have a problem with
your
oil, this light may stay
on after you start your
engine, or come on when
you are driving.
This
indicates that oil is not
going through your engine
quickly enough to keep it
lubricated. The engine could be low on oil, or
could have some other oil
problem. Have it fixed right
away.
The
oil light could also come on in three other situations:
When the ignition is on but the engine is not funning,
the light will come on as a test to show you it is
working, but the light will go out when
you turn the
ignition to “Start? If it doesn’t come on with the

Be sure the posted octane is at least
87. 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 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.
