pulling definitely works but i dont think that is the "correct" way. if you look in between the slats on the grill in the 4 corners, you will see a hole with a square head inside, and a slot in it. put a flathead in the slot, and turn the square head until it lines up with the square hole behind it. should be a 1/8 turn to get them to line up, and that side will pop out. do all 4 and it will come right off. to reinstall, remove the clips from the bumper, and snap them back onto the grill, then snap the grill back into place.
