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.
Rear Cross Traffic Alert
When in Reverse, this feature can provide alerts to help drivers avoid approaching detected left or right cross traffic (such as when backing out of a crowded parking space or driveway with side obstructions)
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.
* 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
