Fuel Gage
When the ignition is on, the fuel gage tells you about
how much fuel you have remaining.Here are four things that some owners ask about. None
of these show a problem with your fuel gage:
·At the gas station, the gas pump shuts off before
the gage reads full.
·It takes a little more or less fuel to ®ll 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
®ll the tank.
·The gage moves a little when you turn a corner or
speed up.
·The gage doesn't go back to empty when you turn
off the ignition.
Low Fuel Warning Light
The light next to the fuel gage will come on brie¯y when
you are starting the engine.
This light comes on when the fuel tank is low on fuel.
