Here are some situations you may experience with your fuel gage. None of these indicate a problem with the fuel gage. Driver Information Center (DIC) The Driver Information Center (DIC) display is located on the instrument panel cluster, below the speedometer. The DIC buttons, if equipped, are located on the steering wheel. The DIC can display information such as the trip odometer, fuel economy, customization features and warning/status messages. If your vehicle is not equipped with the DIC steering wheel buttons, you will not have all of the features listed. You will scroll through the odometer, trip odometer and engine hours by pressing the trip odometer reset stem located on the instrument panel cluster. You will also turn off, or acknowledge, DIC messages by pressing the trip odometer reset stem. See Speedometer and Odometer on page 3-33 for information on features for vehicles without DIC buttons. • At the gas station, the fuel pump shuts off before the gage reads full. • It takes a little more or less fuel to fill up than the fuel gage indicated. For example, the gage 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 gage goes back to empty when you turn off the ignition. If you have a diesel engine, see "Fuel Gage" in the Diesel Engine Supplement. Low Fuel Warning Light The light next to the fuel gage will come on briefly when you are starting the engine. This light comes on when the fuel tank is low on fuel. To turn it off, add fuel to the fuel tank. See Fuel on page 5-6. 3-50
