I tried to install my Scenera last night in my 2001 Pathfinder with leather seats and I could not get a tight install. I am installing it rear facing, on the passangers side (not in the middle, due to the bump from the split bench seat). In my car I have a Britax Marathon and I can always get a tight install in there. I put all my weight in the seat and pulled the belt as much as I could. I also hand my husband pull the belt too and we still couldnt get it as tight as my Britax. The seat moves more than 2 inches to the side if we really put force on it and push it hard. So, the inch rule...is it suppose to be if I put hard porce on it or if I put light force on it? Any suggestions on how to get a tighter install?
