Fuel Used
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 DIC calculates and displays the total amount of fuel used since the last reset operation.
You can reset the Fuel Used mode by depressing and holding the Set button for more than 3 seconds. The value of this mode is retained during ignition OFF.
