-1 When the ignition is on, the
I
fuel gage tells you about
how much fuel you have
left in your tank.
The gage will first indicate EMPTY
(E) before you
are out of fuel, and you should get more fuel as soon
as possible.
Listed are four situations you may experience with your
fuel gage:
At the gas station, the fuel pump shuts off before the
gage reads
FULL (F).
It takes a little more or less fuel to fill up than the
fuel 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 or
speed up.
The gage doesn’t go back to EMPTY (E) when you
turn
off the ignition.
None of these indicate a problem with the fuel gage.
For information
on how to fill your fuel tank, see
“Fuel -- Filling Your Tank” in the Index.
For your fuel tank capacity, see “Fuel
-- Tank Capacity”
in the Index.
For the diesel engine fuel gage, see your Diesel
Engine Supplement.
