Understanding GMC Super Cruise

While it’s true that cars aren’t yet able to drive themselves, there are several advanced driver assistance systems that offer hands-free driving in limited situations. GMC’s Super Cruise system is a Level 2 autonomous driving assistance feature that lets drivers cruise without hands on the wheel. It works on limited-access highways and interstates across the U.S. and Canada.

What is Super Cruise and How Does It Work?

Many new vehicles come with adaptive cruise control, which uses sensors and other technology to maintain a set speed while also keeping the vehicle at a safe distance from others. Some of the more advanced systems bring semi-automated lane changes and other features. GMC vehicles equipped with Super Cruise build on that technology with GPS, cameras, sensors, and LiDAR that help build a digital picture of the world around the car.

Super Cruise lets the driver take their hands off the wheel, but it does not offer a completely autonomous driving experience. The driver must remain alert and be ready to take control of the vehicle at any time, and the system will sound alerts if it detects that the driver is not paying attention. Super Cruise will sound three alerts before deactivating itself and calling an OnStar Emergency-Certified Advisor to assist with any potential medical or other issues. 

GM’s Super Cruise has been around for several years, giving the automaker time to hammer out the details and expand the service area. The number of Super Cruise-compatible roads has exploded in recent years and is now three times larger than it was in 2018, covering all of the U.S. and parts of Canada.

GMC notes that Super Cruise can handle lane changes, but the company advises that it will not respond to an emergency situation and cannot steer to avoid safety issues. The automaker recommends deactivating the system if you’re in an unfamiliar area or see an upcoming road hazard, such as debris or a stopped vehicle. Additionally, while it maintains the vehicle’s speed, it does not monitor speed limits, so it’s important to set the speed within the legal limits. 

Super Cruise works in a staggering number of places, but GMC recommends against using the situation if the road markings are unclear or damaged. The system can recognize visibility issues and warn the driver, but it’s best to pay attention and take over if you notice a problem. Super Cruise should not be used in tunnels or construction zones, and GMC states that drivers should avoid using the system in poor weather conditions, such as snow and heavy rain. Some GMC vehicles offer towing-ready Super Cruise systems, but you should not attempt to tow with the standard tech.
