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 or driver assistance 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. Visibility, weather and road conditions may affect feature performance. Read the vehicle Owner’s Manual
