How do you set my memory seats ON STS?

To set the memory seats on a Cadillac STS, first, adjust the driver's seat to your desired position using the seat controls. Then, press and hold the "Set" button on the door panel until you hear a beep. Next, press one of the numbered memory buttons (1 or 2) to save your settings. Your seat position is now saved and can be recalled by pressing the corresponding memory button.
