First, you've got to really stare at it. Focus hard and make sure there are no distractions. Then straighten your right hand index finger while curling the other three fingers in towards your thumb. Over-lap your thumb over the three curled fingers to hold them securely in place to avaiod any possibility of them suddenly straightening potentially causing injury or a hang nail. Finally, extend arm as to bring index finger within close proximity of ESP button. Continue closing the distance from finger to button until finger comes into contact with button. Gradually increase pressure on button until you hear and feel the button mechanism engage in detents which will either light or unlight the dash mounted icon signifying that ESP as been enabled/disabled. Repeat as often as you like.
I'm a kidder. It's what I do. Sorry, I'm certain you meant somehting completely different but I couldn't resist having a little fun.
