Depending on the trim, interior appointments range from practical cloth seating on the Pro to full-grain leather seating surfaces with plaited contrast stitching on the Denali Ultimate.
Available features include 12-way and 16-way power-adjustable front seats, heated and ventilated seating surfaces, a massage feature, and a heated steering wheel. Smart storage solutions throughout the cabin ensure there's always room for work supplies or weekend gear without sacrificing comfort.
