Mercedes Repair Questions? Ask a Mechanic for Answers ASAP
I believe the headrests are tilt adjustable forward as well as height.
They are on a ratchet system, to reset them you pull them fully forward and then they will go back with your hands, then you come forward again to where you want them. If you do go too far, you then need to repeat the process, so sneak up on the setting.
Hope this helps.
How did you go with your headrests?
I hope my advice has been of assistance to you.
