They're not really hooks, but more like high spots on your floor pan. If you look under the seat bottom you'll see two places where the structure of the seat forms "hooks" or low places in the seat frame. I always install the seat back first, then push the seat bottom in as far as you can. With the seat bottom in place, get in the car facing the rear window. Place your hands, palms up, under the lower edge of the seat on the driver's side. Push the seat bottom straightback as far as you can, almost like you are trying make the top of the seat bottom arch upward. Push hard! You may have to push enough to pop a sweat! As you get the bottom back as far as you can, move your hands down towards the floorboard. Release your grip on the seat and allow the seat bottom to catch on the high spots on the floor pan. Repeat on the passenger side. Now put your hands under the seat and tug upwards gently. You should feel the resistance if the seat bottom has indeed "hooked" on the floor pan. If not, repeat until you do!
