A few days ago, in my 2nd month of ownership (2015 H. Genesis), I was retrieving cash from my banks cash flow interface. In order to use the keyboard, I essentially lowered the driver's seat to a horizontal position. Once I repositioned myself (and the driver's seat) to return home, I realized that I had somehow managed to move the driver seat extender to its extended position. For some reason, I have not yet discovered how to control/retract the extender. Please advise.
