The fuel gage, when the ignition is on, tells you about how much fuel you have left in your tank. The gage will first indicate empty before you are out of fuel, and you should get more fuel as soon as possible. Here are four situations you may experience with your fuel gage. None of these indicate a problem with the fuel gage. • At the gas station, the fuel pump shuts off before the gage reads full.

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 goes back to empty when you turn off the ignition. • The gage pointer moves while cornering, braking or acceleration.
