The fuel gauge in your automobile indicates the amount of fuel that remains in the gas tank. Some fuel gauges have an analogue display while others have a digital or liquid crystal display. Electronic and software malfunctions may cause the fuel gauge in your automobile to inaccurately measure or display the amount of fuel remaining in the gas tank. If this happens, reset your fuel gauge. Each make and model of car has its own specific instructions on how to reset the fuel gauge, but the process is basically the same.

Turn the ignition switch to the "On" position.

Press the "Odo/Trip" button until the odometer is put into "ODO" mode.
