Pop the hood and remove the 6 10mm bolts holding the top of the grille / bumper on. Then go to your fenders and remove the two 7mm screws and 3 push clips. Then there are two 10mm bolts holding the reinforcement to the bottom of the bumper. Once all those are removed, pull each corner of the bumper cover out - away from the fender (youll see that it comes loose from the guide), then stand in the middle of the bumper and pull it toward you. It may get a little stuck where the absorber is in the lower guide.
Before you pull it all the way off, if you have fog lights, now is a good time to reach down and unplug them (or you can do that while you're underneath it removing those two 10mm). then finish pulling the bumper off.
There are three 10mm bolts holding each headlamp in, and a clip on the lower inner corner. Once removed, just pull it toward you.
When you reinstall, make sure you have the headlamp tucked nice and flush in the fender so there is no gap, and tighten up.
