Fuel Gage
I
Your fuel gage is a bar graph. When you fill the tank,
the bar segments will light up. The fuel gage shows
about how much fuel is in your
tank. It works only when
the ignition is on. When the fuel gage shows only two
bar segments the
“LOW’ light will come on. If the fuel
~ supply is in the one bar segment, the yellow warning bar
’ will flash to remind you to get more fuel soon.
At the gas station, the gas pump shuts off before the
gage reads
“F’.
It takes more (or less) gas to fill up than the gage
said. For example, the gage said
1/2 full, but it took
more
- or less - than half of the tank’s, capacity to fill
it.
