Fuel Gage Your fuel gage tells you about how much fuel you have left, when the ignition is on. When the gage reads in the yellow band, a warning chime will sound and the CHECK GAGES warning light will go on, if you have this option. Voltmeter (Option) You may have a voltmeter unless you have the supercharged engine. Here are five things that some owners ask about. None of these show a problem with your fuel gage: 0 At the service station, the gas pump shuts off before the gage reads full. It takes a little more or less fuel fill up than the to gage indicated. For example, the gage may have indicated the tank was half full, but it actually took a 0 little more or less than half the tank's capacity to fill the tank. 0 When the engine is not running, the gage shows the condition of the charging system. Readings outside the red warning zone indicate the normal operating range. Readings in the red warning zone indicate a possible problem in the electrical system. The CHECK GAGES light will also come on, and a warning chime will sound. Have your vehicle serviced immediately. When your engine is not running, but theignition is on (in the RUN position), the gage shows your battery's state of charge in DC volts. The gage moves a little when you turn a corner, speed up, or make ahard stop. The gage doesn't go back toempty when you turn off the ignition. If you have the large span (220")gage, the needle moves more for a given amount of fuel. This does not indicate excessive fuel consumption, and is normal. 0 0 2-65
