No, it wont. We literally just tried it today. We have two Graco Slimfits. Even with the cup-holders folded in and seat in forward facing on 2nd row center using latch, the tilt feature does not work - The slimfit is still too wide. The only way is to squish or damage the outward seat leather. If seat is installed using roof mounted seat belt, it is even worse and tilt is completely blocked.
