Do you have the reclining seat or the seat that folds down?
Is it the regular model or the Hybrid?

These are the two types the books show for the 2009 Camry XLE. Reclining, Folding or a fixed unit that does not move.

If yours is different could you take a couple pictures and we can try to match it or figure it out.

That would be the reclining seat that I included the instructions for. Those three are the only ones that show in the service literature I have. Fixed seat, fold down and recliner.
