Every Sierra Heavy Duty includes active safety and driver-assistance technologies that help while driving and trailering. Sierra HD Pro Safety includes:
Automatic Emergency Braking operates below 80 km/h, and can alert you when it detects a front-end collision is imminent with a vehicle ahead of you. It also can help reduce the collision’s severity or avoid the collision by automatically applying brakes if you have not already, or by enhancing driver braking.
1. 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.
