Fuel Gage
The fuel gage, when the
ignition is on, tells you
about how much fuel you
have left in your tank.
(United States version,
Canada similar.)
The gage will first indicate E (Empty) 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:
D At the gas station, the fuel pump shuts off before the
gage reads F (Full).
D 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.
D The gage moves a little when you turn a corner or
speed up.
D The gage doesn’t go back to E (Empty) when you
turn off the ignition.
None of these indicate a problem with the fuel gage.
