5-14 Instruments and Controls Here are four things that some owners ask about. None of these show a problem with the fuel gauge: . At the service station, the fuel pump shuts off before the gauge reads full. It takes a little more or less fuel to fill up than the gauge indicated. For example, the gauge 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 the tank. The gauge moves a little while turning a corner or speeding up. The gauge takes a few seconds to stabilize after the ignition is turned on, and goes back to empty when the ignition is turned off. . Uplevel Balanced Configuration, Performance Similar Uplevel Simple and Enhanced Configurations When the ignition is on, the fuel gauge indicates about how much fuel is left in the tank. There is an arrow near the fuel gauge pointing to the side of the vehicle the fuel door is on. When the indicator nears empty, the low fuel light comes on. There still is a little fuel left, but the vehicle should be refueled soon. . .
