I just pull the Boxster in to the garage, turn off and remove the key. Plug the adapter into the cigarette lighter, then plug the maintainer into the wall outlet. I then push the button to move the indicator light on the maintainer to the car icon. I usually get two steady orange lights for a short period, and then I get the green light which periodically goes back to orange for awhile and then back to green.
