1. Make sure the engine is off and the ignition switch is in the OFF position.
2. Locate the odometer reset button. It is usually located on the instrument panel, near the speedometer.
3. Press and hold the odometer reset button for about 10 seconds.
4. The change oil soon light should turn off. If it does not, repeat steps 2 and 3.
5. Once the light is off, release the odometer reset button.
Please note that this procedure may vary slightly depending on the exact model and year of your Chevy Lumina. If you are unable to reset the change oil soon light by following these steps, please refer to your vehicle's owner's manual for more information.
