Behind the rear wheels, take off the wheel well.
Remove the row of five bolts from the front edge of the rear bumper, just behind the rear tires, with a Phillips screwdriver.
Reach inside the rear bumper where the bumper meets with the rear quarter panel of the car, just behind the rear tire. Remove the row of bolts with a ratchet and 10mm socket.
Open the trunk and find the row of plastic clips along the top of the bumper on the outside of the trunk. These clips look kind of like plastic circles. Pry them up with a flat screwdriver until they pop out. Pull the bumper off of the car and you're set.
Hope this helps.

try using google sometimes, it's pretty helpful.
