Fuel Gage \ Here are some things that some owners ask about. None of these show a problem with your fuel gage: e At the service station, the gas pump shutsoff before the gage reads full. It takes more (or less) fuel to fill up than the gage indicated. For example, the gage may have indicated half full, but it took more (or less) than half the tank's capacity to fill it. The gage moves up a little when you turn a corner, speed up or make a hard stop. The gage doesn't go back to empty when you turn off the ignition.

When the indicator moves to the edge of the low fuel warning band, the low fuel warning light will come on and a chime will sound. You still have a little fuel left, but you need to get more fuel right away. 3-46
