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 the 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 shows about
how much fuel is
in your
tank.
It works only when
the engine is on. When the
indicator nears
“E,” you
still have a little fuel left. Here
are some concerns owners have had about the fuel
gage. All these situations are normal and indicate
nothing 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
indicated. For example, the gage indicated 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 a corner,
speed
up, or stop your vehicle.
When you turn the engine off, the gage d&sn’t go all
the way back to
“E”.
