Walk within fob range of your S and double click the top. The handles present. However, do not open any door or the lift gate. Walk away. In about a minute the handles will retract. Now, to prove what I am describing, take the fob away from the car, maybe back in the house. Move it far enough away that you are satisfied its not within range of the car. Walk back to the car. Touch a handle. It will present. Now you can open the door.
