Fuel Gage The fuel gage indicates about how much fuel is left in the fuel tank when the ignition is on. Low Fuel Warning Light If the vehicle's fuel is low, a light on the fuel gage, if equipped, will come on and a chime will sound periodically until fuel is added to the fuel tank. It will also come on for a few seconds when the ignition is turned on as a check to indicate it is working. If it does not come on then, have it fixed. For vehicles with a DIC, a LOW FUEL message will appear. See DIC Warnings and Messages on page 3-53 for more information. Check Gas Cap Light When the indicator nears empty, there is still a little fuel left, but you should get more fuel soon. Here are four things that some owners ask about. All these things are normal and do not indicate that anything is wrong with the fuel gage: • At the gas station, the pump shuts off before the gage reads full. • It takes more, or less, fuel to fill up than the gage reads. For example, the gage reads half full, but it took more, or less, than half of the tank's capacity to fill it. • The gage pointer may move while cornering, braking or accelerating. • The gage may not indicate empty when the ignition is turned off. 3-46 If equipped, this light will come on and a chime will sound if your gas cap is not securely fastened.
