Fuel Gage When the ignition is on, the fuel gagetells you about how much fuelyou have left in your tank. It takes a little more or less fuel to fill up than the fuel 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 capacityto 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 turn off the ignition. None of these indicate a problem with the fuel gage. The gagewill first indicateEMPTY (E) before you are out of fuel, and you should get more fuel as soon as possible. Listed are four situationsyou may experience with your fuel gage: At the gas station, the fuel pump shuts off before the gage reads FULL (F). For information on how to fill your fuel tank, see "Fuel -- Filling Your Tank" in the Index. For your fuel tank capacity, see "Fuel -- Tank Capacity" in the Index. For the diesel engine fuel gage, see your Diesel Engine Supplement. 2-74
