Fuel Gage
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 four things that some owners ask about. None
of these show a problem with your fuel gage:
0
0
0
An amber light will come on below the gage when the
fuel tank is near EMPTY (E).
0
At the service station, the gas 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
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
t u r n off the ignition.
