Safety

ADVANCED SAFETY TECHNOLOGIES

​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 manoeuvring.

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.

Available Following Distance Indicator

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 Low Speed Forward Automatic Braking

If Sierra is travelling 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.


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).


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.


Lane Change Alert with Side Blind Zone Alert

Provides side-mirror alerts to drivers when a detected vehicle is moving in, or rapidly approaching, their side blind zone during a lane-change manoeuvre.


Available Lane Keep Assist with Lane Departure Warning

Provides gentle steering wheel turns (and, if necessary, Lane Departure Warning alerts), to help drivers avoid collisions due to unintentionally drifting out of their lane when they are not actively steering and their turn signal is not activated.


Available Forward Collision Alert

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.


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.
