ADVANCED SAFETY TECHNOLOGY
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. With innovation as a foundation, Sierra offers advanced safety technologies and driver-centric alerts.
AVAILABLE HD REAR VISION CAMERA
When in Reverse, the driver can view the scene directly behind the vehicle on the infotainment screen, to help the driver park and avoid nearby objects during low-speed maneuvering.
AVAILABLE FORWARD COLLISION ALERT13
If the system detects that a front-end collision situation is imminent while following a detected vehicle, the system can alert the driver to a potential collision. It also can alert the driver if the driver is following a detected vehicle much too closely.
AVAILABLE FRONT PEDESTRIAN BRAKING
If the system detects that a pedestrian is directly ahead and a collision is imminent, and the driver has not already applied the brakes, the system can alert the driver and may even automatically apply the brakes to help the driver avoid or reduce the harm caused by the collision. Performance is limited at night.
AVAILABLE LOW SPEED FORWARD AUTOMATIC BRAKING
If Sierra is traveling at a low speed and the system detects that a front-end collision situation is imminent while following a detected vehicle and the driver has not already applied the brakes, the system can automatically apply the brakes to help reduce the collision’s severity. The system may even help avoid the collision at very low speeds.
AVAILABLE INTELLIBEAM HEADLAMPS
When driving conditions are dark, IntelliBeam headlamps automatically turn on the vehicle’s high beams. When oncoming headlamps or taillights are detected, IntelliBeam switches back to low beams.

This system can provide drivers with the following (or headway) time to a moving vehicle detected in front of the vehicle to help them know if they are following too closely.
AVAILABLE SAFETY ALERT SEAT
The GM-patented Safety Alert Seat provides the driver the option to choose seat-bottom vibration pulses instead of audible crash-avoidance alerts.
* 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.
