With the ignition on and the engine off, press the brake pedal three times and hold it for 15-20 seconds on the third press, then turn the key off, wait briefly, and restart to see if the Change Oil light clears. If it does not, ask a Pontiac dealer service department to reset it.
The owner of a 2002 Pontiac Aztec with 74,100 miles, who changes the oil about every 3,000 miles, asked how to reset the Change Oil light. An expert said a GM method used on their truck may work: key on without starting, brake pressed three times with the third press held 15-20 seconds, key off, wait, then start. If that fails, they recommended the Pontiac dealer service department.
