Fuel Gage The fuel gage shows approximately how much fuel is in the fuel tank. It works only when the engine is on. All of the following situations are normal and do not indicate that anything is wrong with the fuel gage: • At the gas station the gas pump shuts off before the gage reads full. • The gage may change when you turn, stop quickly or accelerate quickly. • It takes a little more or less fuel to fill the tank than the gage indicated. For example, the gage may have indicated that the tank was half full, but it actually took a little more or less than half the tank's capacity to fill the tank. If the fuel supply gets low, the "FUEL LEVEL LOW" message will appear on the Driver Information Center (DIC) and a single chime will sound. See DIC Warnings and Messages on page 3-80 for more information. 3-73
