Can anyone tell me and/or send pictures on how to lower the headrest on a 2004 e320 w211

????
I'd be looking in the owne'rs manual....and I am not being flip about it.
I would also think that the small little button above the seat recliner would raise or lower the headrest or are you asking about the rear headrest?

The car has to be running, then push the button on the dash panel. Mine were vacuum operated as I recall. It needs the engine running to create the vacuum for the system.

Thanks for the information. You were right. Button on the control panel, and the car does have to be running. Owners Manuel fails to give you that detail.
