There are various procedures floating around but this as the one I use,
1. Never touch the break pedal & key remains inserted the entire time
2. Insert key and push START Button
3. Press and HOLD accelerator pedal for 30 seconds (some say 5, some say 25 seconds - I did 30 to be sure).
4. WITHOUT RELEASING THE ACCELERATOR PEDAL, push the START Button
5. Release accelerator pedal
6. Wait full 2 minutes
7. Start car normally
