On my '04 coupe, the spoiler goes up at 58 and down at 38. You only have to cross 58 for a fraction of a second and its up and it stays up until you slow below 38 or push the switch to manually lower it. In my previous job, I had to drive 15 miles on a twisty back country road to get to work. Slowing and speeding up on that road with the spoiler controlled automatically made it look like a flapping wing. I got tired of listening to it and started manually raising it as I left.
