In the video, a man is seen walking towards a car parked on the side of the road. He opens the car door and proceeds to sit in the back seat. The man then demonstrates how to adjust the seat using the controls on the door. He pulls the lever to recline the seat and then pushes it back to the original position. The man then adjusts the headrest and leans back to test the comfort of the seat. The video provides a clear view of the seat adjustment process and the comfort it provides.
