If it eventually doesn't go off You will need to try different ways to reset it. Another way that You can reset it is by opening up the hood, finding the battery, unhooking the negative side of the battery and waiting around 5 to 10 minutes or so. If that doesn't work You will need to use the scanner by finding the diagnostic input jack, which is below the steering column either in the center or right side of the dashboard panel. Plug in the scanner, turn it on, turn the car engine on, clear the codes with the scanner, unplug it and start the vehicle.
