Low Fuel
WARNING: This page is about a different car, the 2003 Pontiac Aztek and 2003 Buick Rendezvous. However, it is still accessible from the selected car via links, so may be relevant.
The IPC illuminates the LOW FUEL indicator in the message center when the fuel level is less than 11 percent (1/16) of a tank. The IPC receives a class 2 message from the PCM indicating fuel level percent.
