Follow these steps to remove the front bumper. This does not include disconnecting the fog lights, I do not have them so you will want to unplug the lights before you run a marathon with the bumper.

1. Pop the hood. You will find (as pictured) 6 plastic buttons:

2. Notice each one has a notch on two sides. Slide a flat tip screwdriver into the slot and pull up. Like so:

Once they pop up, they pull right out. Take out all six. 

3. There are about 8 more under the bumper. Time to get down and dirty! get them all. I don't have a picture of this, but they are easy to find.

4. Now get a 9/32nd socket and a 1/4" drive ratchet. There are three screws on each side on the edge of the wheel wells, they are pointed out in this picture. Remove them.

5. Your done. starting on the sides pull out slightly away from the car.
