Fuel Level Low
WARNING: This page is about a different car, the 2007 Chevrolet Monte Carlo and 2007 Chevrolet Impala. However, it is still accessible from the selected car via links, so may be relevant.
The driver information center (DIC) displays FUEL LEVEL LOW when the instrument panel cluster (IPC) determines that the fuel level is less than 10.98 percent. The IPC receives a GMLAN message indicating the fuel level information from the engine control module (ECM).
