Fuel Gage F Low Fuel Light UNLEADED FUEL ONL' L - 1 b 1 Your fuel gage tells you about how much fuel you have left when the ignition is on. When the indicator nears EMPTY (E), you still have a little fuel left,but you should get more soon. LOW If your fuel is low, a light will come on and stay on until you add fuel. It will a also come on for few seconds when you first turn on the ignition as a check to show you it's working. If it doesn't come on then, have it fixed. Here are some things owners ask about.All these situations are normal and do not show a problem with your fuel gage: 0 At the service station, the pump shuts before the off gage reads FULL (F). It takes a little more or less fuel to fill 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 fill it. The gage moves a little when you turn a corner or speed up. 0 0
