How to Reset an Oil Change Light on a 2002 Impala

The General Motors Oil Life Monitoring System measures the amount of usable life that is left in the motor oil since the last oil change as a percentage. The system calculates the oil life usage based on engine starts and the length of drive time, among other variables. This allows the owner to change the engine oil at just the right interval. The system either displays a percentage of remaining oil life, or will turn on a warning light when it is time for an oil change. The light must be reset manually when the oil is changed.
