Low Fuel
WARNING: This page is about a different car, the 2006 Pontiac Montana SV6, 2006 Chevrolet Uplander, and 2006 Buick Terraza. However, it is still accessible from the selected car via links, so may be relevant.
The instrument panel cluster (IPC) illuminates the LOW FUEL message in the message center and the LOW FUEL indicator in the IPC when the powertrain control module (PCM) determines that the fuel level is less than 8.2 percent. The IPC receives a class 2 message indicating the fuel level from the ECM/PCM.
