1. Forward Collision Alert

This system warns you when a potential front-end collision is detected, giving you enough time to apply the brakes and avoid impact—especially useful during fast-paced highway driving.

3. Front Pedestrian Braking

City driving is safer with sensors that detect pedestrians crossing your path. The system alerts you and applies brakes automatically if needed to prevent collisions.

5. Lane Departure Warning

This feature helps prevent unintentional lane drifting by notifying you with alerts when your Sierra veers out of its lane—keeping you safer on narrow or busy roads.

6. Buckle to Drive

Before your Sierra can shift out of PARK, this system ensures you’re buckled in. It also reminds passengers to do the same, putting safety first every time you start the engine.

7. Automatic Emergency Braking

When you're too close to another vehicle, this feature engages to help reduce the severity of a crash—or avoid it entirely—by automatically applying the brakes.
