GMC Pro Safety System

Standard in all trims of the 2026 GMC Sierra HD is the GMC Pro Safety System suite of safety features, which include the following:

• Forward Collision Alert

Available Adaptive Cruise Control

Available in the lower-end trim levels and standard in the AT4, AT4X, Denali, and Denali Ultimate trims of the 2026 GMC Sierra HD is the available Adaptive Cruise Control. This safety system allows you to automatically keep a driver-selected-wide gap from the vehicle you’re following while you drive. This means you don’t have to worry about braking or accelerating, as the system will automatically do so for you so that you do not get closer to the vehicle in front of you than the distance you choose to input.
