How to Turn Off the Change Oil Light in a Pontiac Grand Prix

The last two Pontiac Grand Prix body styles (1997 to 2003 and 2004 to 2008) before its demise had GM's Oil Life Monitor. Although the procedure for resetting the system (which turns off the "Change Oil" light) is different between the two models, the systems function similarly. A reminder light comes on when it's time for an oil change (about every 3,000 miles); after you change the oil, the system requires resetting to shut off the light.

Instructions

1997 to 2003 Grand Prix

1. Insert your key into the ignition; crank the engine, or turn the key to "On."

2. Press the "Mode" button on your dash control panel until the light behind "Oil Life" illuminates.

3. Hold the "Reset" button for three seconds. The light behind "Oil Life" will flash; the display will change to "100%."

2004 to 2008 Grand Prix

1. Insert your key into the ignition; crank the engine, or turn it to "On" to activate the electronics.

2. Press the "Options" button (symbol "i") until "Engine Oil Monitor" appears on the display screen.

3. Hold the "Reset" button ("arrow" symbol) for a few seconds. The display will flash. Turn the key to "Off" or "Lock" to finish resetting the system.
