Towing becomes less stressful with the In-Vehicle Trailering App. This helpful system offers a checklist, trailer maintenance reminders, security alerts, and trailer electrical diagnostics. The Hitch Guidance with Hitch View feature uses pan, zoom, and tilt controls to help you line up your trailer with confidence. Select trims add HD Surround Vision, giving drivers an overhead camera view of their surroundings on the center display. Trailer Side Blind Zone Alert and Trailer Tire Pressure Monitor Sensors add extra awareness when hauling heavy loads.
Upper trims like the Denali Ultimate include a Multicolor 15-inch Diagonal Head-Up Display, projecting key information onto the windshield. A Rear Camera Mirror replaces the standard view with a wide camera image of what is behind you. The Bose Premium Series 12-speaker audio system rounds out the cabin with rich sound quality.
