2009 Chevrolet Silverado 2500 HD Extended Cab Owner's Manual - Page 238

When the fuel tank is low the FUEL LEVEL LOW message appears. See DIC Warnings and Messages on page 3-66 for more information. Here are some situations owners can experience with the fuel gage. None of these indicate a problem with the fuel gage. Low Fuel Warning Light This light, under the fuel gage, comes on briefly while the engine is being started. • 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 fuel tank's capacity to fill it. This light and a chime comes on when the fuel tank is low on fuel. The Driver Information Center also displays a "FUEL LEVEL LOW" message. See DIC Warnings and Messages on page 3-66 for more information. When fuel is added this light and message should go off. If it does not, have the vehicle serviced by your dealer/retailer. • The gage goes back to empty when the ignition is turned off. For a diesel engine, see "Fuel Gage" in the Diesel Engine Supplement. 3-52
