**Due to global Semi-Conductor supply shortages, GM vehicles built after July 19, 2021 may not have some standard features and options. Please check with your local GMC dealer to confirm the vehicle’s specifications prior to purchase. Vehicles not equipped with Automatic Stop/Start will be less fuel efficient.

A 4.2" Digital Driver Information Center shows you key information like an Off-Road Inclinometer that shows the fore-and-aft tilt, front tire angle, and left-and-right tilt.
