You don't need to remove them, but you often have to lower them if they're extended too far. Everything folds almost flat, with a slight incline near the front. Also make sure you don'r have something on the seat itself, or something stuck in the hinges or crack.Did you remove the middle row’s headrest? The Pilot is not my daily driver so I can’t recall if this is applicable.
The single seat actually does go flatI have a 07 ex-l I believe. Saw a video where a 2006 had its seats fold flat
Also think I saw a video of an 07 whose seat also folded flat....So are my seats suppose to fold flat?
If so how do I do it because they dont
