Its should still be adjustable mine looks like it set all the way up "How to" - Manual Seat Operation | Chevy Cruze | Chevrolet - YouTubeThere is only two levers on my 2012 passenger seat, one on the seat side that adjusts the seat cushion height & one on the side of the seat back that adjusts the seat back angle. Only thing in the front is to move the seat forward & backward.
My drivers seat is power so only one lever for the seat back.
So your saying there used to be more adjustment of the non-power seat in 2011? That would explain why the passenger seat never feels comfortable in my 2012. the seat cushion adjustment moves the seat floor up & down but at the same time is changing the angle of the seat bottom making things not comfortable.
