Trying to figure out why when and how does my driver seat headrest move on its own i cant seem to figure this out anybody got some info

 

It moves up or down depending on seat positioning...how far back the seat is and how much it's reclined....

If you are facing the seat you will see a circular indention in the leather on top of the seat to the left of the headrest. If you push on it you will feel a button that will allow you to adjust the headrest manually.

 

Thanks man appreciate it
