Understanding GMC Super Cruise

Vehicle technology has progressed tremendously over the past few years, but the market isn’t yet at a point where cars can drive themselves without a human to assist. Partial automation is possible, however, reaching Level 2 on the automation scale, which is where GMC’s Super Cruise falls on the spectrum. The hands-free driving assistance function works on limited-access highways and helps reduce driver fatigue by managing some of the more mundane aspects of driving.

What is Super Cruise and How Does It Work?

You’ve probably heard of adaptive cruise control, which builds on traditional cruise control with features that help it maintain distance between other cars. Some systems also offer lane changes and stop-and-go, but even the most advanced adaptive cruise control systems fall short compared to Super Cruise. GMC vehicles equipped with the feature have GPS, cameras, sensors, and LiDAR to build a digital picture of the world around you. 

Though the driver can remove their hands from the wheel, they must remain alert and ready to take control at any time. The system alerts drivers if it detects that they are not paying attention, giving three warnings before deactivating itself and bringing the vehicle to a stop. It will also notify an OnStar Emergency-Certified advisor to assist if a medical issue or other problem is taking the driver’s attention.

Since Super Cruise has been around for a while, General Motors has had time to expand the number of roads where it works. While they are primarily highways and interstates, the number of available Super Cruise-compatible roads has tripled since 2018 and now covers all of the country and parts of Canada. 

Super Cruise can assist with lane changes, but it will not steer to avoid a safety issue, such as debris in the road. GMC recommends deactivating the system if you’re unsure of road conditions or need to maneuver around an obstacle. Additionally, while it maintains the vehicle’s speed, it does not monitor speed limits, so it’s essential to set the speed within the legal limits. 

GMC recommends against using Super Cruise if you are in a dangerous or unfamiliar area and when the lane markings are unclear or difficult to see. Super Cruise recognizes when the markings are difficult to detect and will sound a warning. Don’t use Super Cruise in a tunnel or construction zone or in poor weather conditions like snow and heavy rain. Some GMC vehicles offer towing-ready Super Cruise systems, but you should not attempt to tow with the standard tech.
