Fuel Gage
Low Fuel Light
1 12
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.
Here are some things owners ask about. All these
situations are normal and do not show a problem with
your fuel gage:
At the service station, the pump shuts off before the
gage reads FULL (F).
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.
If your fuel is low, a circular
light on your instrument
panel cluster will come on
and stay on and a chime will
sound periodically until you
add fuel. It will also come
on for a few seconds when
you first turn on the ignition
as a check to show you it's
working. If it doesn't come
on then, have it fixed.
