I have a 2015 Q50 with deluxe touring, which comes with the 60/40 folding rear seats. I consulted the manual and am only able to fold down the smaller seat (the "40" side). Does anyone know if the larger seat folds as well? I asked Infiniti via chat and they seemed dumbfounded by the question of whether the other seat folds down.

On each side you should have a pull that will allow that side to be folded. So, yes, both should fold down.

But, I don't have the deluxe touring so I can't go out and video it for ya.....
