Ultrasonic front and rear park assist, rear cross traffic braking, and rear pedestrian detection provide awareness in tight spaces. The multicolor head-up display delivers critical information without distraction.
Off-road capability defines the AT4X. The off-road suspension, hill descent control, and driver-selectable full-locking differentials deliver confidence on rough terrain.

The gloss black header with dark nickel grille insert bars and 18-inch painted aluminum wheels distinguish this truck's aggressive stance.
Practicality meets luxury in every detail. The MultiPro tailgate step lights illuminate your work area, the sport step simplifies entry and exit, and the fleet of USB ports including Type-C ports and wireless charging keeps devices powered. The 120-volt bed-mounted power outlet extends workshop capabilities directly to your truck bed.
