Hmmm so coincidentally, last night I came across this video and at about 3:42 they discuss just this!
So did they manually adjust the seating position forward first, and then folded the seat? Because as said above: folding the seat with the headrest lever does not slide the seat forward, right?
They sure make it look as if it is done in 1 go,but if it means having to find back your seat position (no memory on the seats
remember), it's very inpractical but perhaps doable on exceptional occasions.
