Rear Emergency Automatic Braking

WARNING: This page is about a different car, the 2016 Cadillac ATS. However, it is still accessible from the selected car via links, so may be relevant.

The rear automatic braking system is designed to help avoid or reduce the harm caused by backing crashes. If the system detects the vehicle is backing too fast to avoid a collision, it may automatically brake hard to a stop.

With the input from the rear short range radar and park assist system, the active safety control module attempts to avoid imminent collision by automatically braking the vehicle when going in reverse. Two levels of warning are used to encourage the driver to take control. The first level will pulse the left and right sides of the seat twice (if equipped and enabled) or beep once when an object is first detected. When the system detects a potential collision, the second level will provide five pulses on the left and right sides of the driver seat or five beeps, and there may be a brief, sharp application of the brakes.

Pressing the brake pedal after the vehicle comes to a stop will release the rear automatic braking. Also, when it is safe to do so, pressing the accelerator pedal firmly at any time will override the rear automatic braking.
