Fuel Gage UNLEADED FUEL ONLY Here are four things that some owners ask about. None of these show a problem with your fuel gage: At the service station, the gas pump shuts off before the gage reads FULL (F). 0 It takes a little more or less fuel to fill up the gage than indicated. For example, the gage may have indicated the tank was half full, but it actually tooka little more or less than halfthe tank's capacity tofill the tank. The gage moves a little when you turn a corner, brake or speed up. The gage doesn't go back to EMPTY (E) when you turn off the ignition. United States Low Fuel Warning Light When there is between 4 gallons (15 L) and 2 gallons (7.6 L) of fuel left in the tank, the warning light next to the fuel symbol will go on. This light will also come on when you turn on the ignition, but the engine is not running, to show you it is working. If it doesn't come on as you start your vehicle, have it fixed right away. Canadian Your fuel gage tells you about how much fuel you have left, when the ignition is on. When the gage first indicates EMPTY (E), you still have a little fuel left, but you should get more soon. After filling the fuel tank, the gage will not read FULL (F) until the ignition is turned on. 2-98
