Additional features include active safety systems like lane keep assist, forward collision alert, low speed automatic braking, parking sensors, a rear vision camera, and IntelliBeam headlights. It also adds the enhanced driver alert package, chrome exterior accents, a trailering equipment package with an integrated trailer brake controller, and the upgraded suspension designed for improved ride control under heavy loads.
