This is my first car that has had such a customizable seat and I'm completely clueless on how I should be adjusting it. Right now, if I drive for an hour or so, my lower back starts to ache and burn. I believe that's what the lumbar support is for but I have yet to figure out the best way to have it. No setting feels particularly different from the others when just seated. Any tips or tricks on how to adjust the seat for the best comfort and no pain?
