That's def how you do it. Did you maybe not push the acc all the way down? How many times did you try it?

 

You might actually be performing the procedure too slowly. Make sure you push the go pedal all the way to the floor, but do it 3 times within say, 3 seconds. The whole thing must be done within a 10 second time frame... ignition to the 'on' position, press pedal 3 times, ignition to 'off'. It's worked everytime that I've done it this way. Just a suggestion... I hope it works.

 

Thanks for the 10 second time frame, that was the problem. I just did it too slowly.
