GMC is putting some new tech goodies in the 2021 Sierra. There will be three new features available for towing trailers - Jack-Knife Alert, Trailer Length Indicator and the enhanced Rear Trailer View.
- Jack-Knife Alert tracks the position of your trailer and warns you if the latter’s front end is approaching your truck.
- Trailer Length Indicator is displayed as a red overlay twice the length of the compatible trailer on your screen, showing you when other vehicles are present and may interfere with a lane-changing maneuver.
- Enhanced Rear Trailer View now gets guidelines and a Trailer-Angle Indicator to assist you while backing up.
These are all pretty handy features for anyone that regularly uses a trailer. Especially trailer length indicator.
