Super Cruise hands-free driving assistance with automatic lane changing technology makes long highway stretches less taxing, while the onboard navigation system keeps you on course.

For those who tow, the Max Trailering Package and Enhanced Trailering Technology provide comprehensive capability. The integrated trailer brake controller, Hitch View camera, and Smart Trailer Integration Indicator work together to make towing safer and more manageable. The wired auxiliary trailer camera gives you clear visibility of your trailer at all times. The Air Ride Adaptive Suspension with Magnetic Ride Control automatically adjusts to road conditions and load, maintaining composure whether you're unloaded or towing.
