Fuel Gage
112
The fuel gage tells
you about how much
fuel you have
remaining when the
ignition is on. When
the gage first indicates
empty, you still have
a
little fuel left, but you
should get more fuel
soon.
Here are four things that some owners ask about. None of these show a
problem with your fuel gage:
0
At the gas station, the gas pump shuts off before the gage reads 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.
0
The gage moves a little when you turn a comer or speed up.
The gage doesn't go back to empty when you turn off the ignition.
For your fuel tank capacity, see the Index under "Fluid Capacities.''
