How do I put my headrest back in place. I picked it up from the body shop and it in place properly

 

If you are talking about the driver's side headrest, it is supposed to adjust itself automatically based on seat position (fore and aft). If the automatic placement doesn't work, there is a button embedded in the seat back, denoted by a very slightly visible circle in the leather. It is located on the top of the seat back, towards the middle of the car next to the inner post that the headrest rides on. Push it down and you should be able to manually adjust the headrest.

If you have an owner's manual, it should be around page 25 (small blurb) and pages 30 and 31 (how to adjust both the passenger's and driver's headrests). If you don't have an owner's manual, you can download one from Lexus or create an account and Lexus will send you a free printed manual:

Once the headrest is manually adjusted, does the seat reclining continue to automatically adjust the headrest?
