For 2013 and earlier models, begin by opening the 
Hood and removing the hood-to-grille retaining fasteners, then detach the radiator grille from the hood, with installation being the reverse of removal. For 2014 and later models, open the hood and remove the grille-to-radiator support mounting bolts and clips, then use a trim tool to carefully pry the grille up and outwards to release the plastic fasteners, followed by detaching the grille from the radiator support and front 
Bumper, with installation also being the reverse of removal.
