The heated steering wheel adds another layer of convenience during colder months. A power sunroof floods the cabin with natural light, while leather-appointed seating surfaces and color-keyed carpeting elevate the overall ambiance.

The system supports multiple USB ports strategically placed throughout the cabin, including rear charging-only ports. Steering wheel audio controls let you manage entertainment and calls without taking your hands off the wheel.
Safety and convenience features work together to protect occupants and simplify daily driving. Lane Keep Assist, Forward Collision Alert, and Automatic Emergency Braking help prevent accidents. The adaptive cruise control maintains your desired distance from traffic ahead, while lane change alerts monitor your blind zones. Rear cross traffic alert provides additional awareness when backing up. A suite of parking assists, including ultrasonic sensors and hitch guidance with hitch view, makes maneuvering easier in tight spaces.
For truck owners who work hard, this Sierra is built to work harder. The ProGrade Trailering System manages towing with confidence, while the integrated trailer brake controller and in-vehicle trailering app keep everything under control. An auto-locking rear differential and hill descent control enhance off-road capability.
