Features

ADVANCED SAFETY TECHNOLOGY
Available safety technologies provide driver-centric alerts to help enhance your awareness of the road and surrounding vehicles.


Due to global Semi-Conductor supply shortages, GM vehicles 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.

Safety features are no substitute for the driver’s responsibility to operate the vehicle in a safe manner. The driver should remain attentive to traffic, surroundings and road conditions at all times. Read the Owner’s Manual for more important safety information.

Always use safety belts and the correct child restraint for your child’s age and size, even with air bags. Even in vehicles equipped with the Passenger Sensing System, children are safer when properly secured in a rear seat in the appropriate infant, child or booster seat. Never place a rear-facing infant restraint in the front seat of any vehicle equipped with an active frontal air bag. See the Owner’s Manual and the child safety seat instructions for more safety information.
