Three years of OnStar One service comes standard, providing emergency assistance, navigation, and vehicle diagnostics.

Technology integration is comprehensive throughout this vehicle. The 16.8" GMC Connected Navigation system works seamlessly with Apple CarPlay and Android Auto, while the Bose audio system delivers premium sound quality. The 15" Head-Up Display projects critical information directly into your line of sight, and the rear seat media system keeps passengers entertained on long journeys. Auto-dimming features on the interior mirror and exterior door mirrors enhance convenience and safety.

Power-retractable assist steps make entry and exit easier, while blind zone steering assist with trailering adds an extra layer of security when hauling.

Safety features are extensive. Multiple airbag systems, including dual front impact, dual front side impact, and overhead airbags, work with electronic stability control and traction control. Driver attention assist monitors alertness on longer drives, while the glass breakage sensor and theft-deterrent alarm system protect your investment. The 4-wheel disc ABS braking system provides responsive stopping power in all conditions.

The exterior presents a commanding presence with the AT4 Black Appearance Package, which includes black nameplates, an illuminated front black GMC emblem, and a black roof-mounted luggage rack with side rails. The 20" machined and painted wheels complement the silver finish, while the dual exhaust system and front high-approach angle fascia underscore the vehicle's capable design. Red horizontal-mounted recovery hooks and body-color door handles with bright front and rear door sill plates add purposeful detail.
