With the car turned off, hold down the accelerator pedal, insert the key, and turn it 2 times (do not start the car.). The icons will light up. Wait 20 seconds. Do not release the pedal. When the check engine light starts blinking, turn off the car completely. Take out the key. Take your foot off the pedal. Then start the car. I got it the second time
