First lift your back seat base up and forward. It should lift straight out no bolts or screw's there.
Next, this step is much harder, there are 2 star screws on each side at the bottom of the back seat. Unscrew them first. Now take out the head rest's pull them all the way to the top. Do this very slowly. Take them out if they are hard to take all the way out , on the window side of each head rest there is a clip at the base of the head rest two bar's. pull that out and they will come straight out.
Next after both head rest's are out there are 4 plugs where the head rests slide into it is very important to take your time here. You have to remove these plugs because they keep your seat in. The 2 plugs closest to the window's first remove there caps. To do this use a flat headed scew driver and carefully prier the cap off slowly half way because there is a sliding clip on the outer of the caps that have spring's in them. as you are taking them off slowly the clip will lift off and slide out the clip. repeat this on the other side first. Now Take a large flat headed scew driver and put it under the plug and lift it straight up. The plugs are about 3 inches long. Repeat this on the other window plug. Now the inner plugs have a cer clip that you have to pull half way out . To do this take a small pointy screw driver and pull the clip towards the back window and almost out. Next take the Big flat head screw driver and repeat the same lifting Technique that you used with the other 2 plugs and lift them out slowly.
Now you can carefully lift your back seat up and out. You will have to use your palms and hit up on the back seat afew times to loosen it up. and out she comes.
