The AT4X trim combines rugged utility with refined comfort. A diesel engine with an engine block heater provides the torque and efficiency needed for heavy hauling, while the 220-amp alternator ensures reliable electrical capacity for work and accessories. The truck features full grain leather seating, heated and ventilated front seats, and heated rear seating—creating an environment that rewards both long workdays and extended journeys.
Technology integration keeps you connected and in control. Wireless phone projection through Apple CarPlay and Android Auto connects your devices seamlessly. The in-vehicle trailering system app and trailer tire pressure monitor sensors simplify towing operations. Ultrasonic front and rear park assist, rear cross traffic alert, and trailer side blind zone alert enhance confidence in any situation.
Safety systems work together to protect what matters. Automatic emergency braking, forward pedestrian braking, and lane departure warning systems provide active protection. The safety alert seat provides haptic feedback to enhance awareness. A comprehensive airbag system, including overhead airbags and occupant sensing technology, surrounds you with multiple layers of protection.
The AT4X's off-road suspension and 2-speed active transfer case deliver genuine capability when pavement ends. Black premium floor liners protect the cabin, while the electric rear window and power sliding functionality add everyday convenience. Memory settings for the driver's seat and power moonroof address comfort during regular operation.
