Fuel Gage Your fuel gage tells you about how much fuel you have left when the ignition is on. \ F k \ Here are four things 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 gas pump shuts off before the gage reads full. e It takes a little more (or less) fuel to fill up than the gage reads. For example, the gage read 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 speeding up. The gage may not indicate empty when the ignition is turned off. United States Canada e When the indicator nears empty, you still have a little fuel left, but you should get more soon. If your fuel is low, the warning message in the message center will come on. See Low Fuel Warning Message on page 3-55. e 3-47
