GM Automatic Emergency Braking Systems Explained

GM has a wide swath of safety technologies available across its vehicle portfolio, with many of the systems offering different levels of capability and specific areas of focus. Among these is a cornucopia of different emergency braking systems. Now, GM Authority is taking a closer look at The General’s various automatic emergency braking systems with the following explainer.

Collision Alert, part of the GM automatic emergency braking technologies.

In an attempt to simplify the automatic emergency braking system feature lineup, we’ve broken the systems into two groups – systems that focus on forward braking, and systems that focus on reverse braking. To note, most of these systems employ either a visual camera system, a radar system, or both. Each system covered here includes the official system name, related RPO code, and a brief explanation of the system’s capabilities.

Front GM Automatic Emergency Braking Systems

Following Distance Indicator (RPO code UE4) – this is the most basic system of the bunch, and in a way, helps to guide the other frontal assist systems. Following Distance Indicator uses Forward Collision Alert sensors to provide the driver with the following time to the vehicle in front, indicating if the driver is following too closely.

Forward Collision Alert (RPO code UEU) – otherwise known as FCA, Forward Collision Alert uses either radar or a front-mounted camera to monitor traffic ahead of the vehicle and alert the driver if the vehicle is moving or if it has come to a stop.

Automatic Emergency Braking (RPO code UHY) and Enhanced Automatic Emergency Braking (RPO code UGN) – AEB and EAEB takes things a step further by applying the brakes if an imminent collision is detected. The difference between AEB and EAEB is that AEB uses camera systems to detect an imminent collision and will apply the brakes between 5 mph and 50 mph, while EAEB uses both radar and cameras to detect an imminent collision and will apply the brakes at 2 mph and above.

Front Pedestrian Braking (RPO code UKJ) – Front Pedestrian Braking can detect a pedestrian in front of the vehicle and automatically apply the brakes if a potential collision is detected.

Front Pedestrian and Bicyclist Braking (RPO code UKT) – Front Pedestrian and Bicyclist Braking upgrades Front Pedestrian Braking to detect bicyclists as well.

Intersection Automatic Emergency Braking (RPO code CTB) – Intersection Automatic Emergency Braking will apply the brakes if a car is detected in cross traffic, rather than simply directly in front of the vehicle.

Rear GM Automatic Emergency Braking Systems

Rear Cross Traffic Alert (RPO code UFG) – provides the driver with an alert if another vehicle is detected in the rear while backing up.

Rear Cross Traffic Braking (RPO code UFB) – while backing up, will automatically apply the brakes if another vehicle is detected traveling behind and perpendicular to the vehicle.

Reverse Automatic Braking (RPO code UVZ) – while backing up, will automatically apply the brakes if another vehicle is detected directly behind the vehicle.

Rear Pedestrian Alert (RPO code UKK) – the same as Front Pedestrian Braking, but for the rear of the vehicle while backing up.

  1. Will these avoidance systems detect smaller obstacles such as children, trash receptacles, and parking barriers?

  2. It all sounds good, I only wish it worked. I have a 2023 Silverado High Country 1500 and my wife has a 2021 Lexus RX450H (Hybrid). I was backing out of a parking spot and a car was coming, and the car stopped immediately. Pulling into the garage, it stops about 12” before contacting the wall. In both cases, it warns me with yellow, then red flashing lights on the dashboard.
    The High Country, on the other hand, flashes red on the dashboard and the windshield for both similar reasons, but allowed the truck to hit the garage wall forward, and a post while it reverse. I checked, and ALL warnings are on.

    1. Oh buddy it works. I do not ever want to feel that again. Airbags and now that is something I am scared of while driving. I felt like if I did nothing t have my seatbelt on, you would have peeled me from the windshield. I was more concerned about being hit in the back. I was so embarrassed when traffic started moving it took six seconds to make sure I was safe before I could move forward!! I am good
