CTA False Alerts

Due to the nature of radar technology, there may be certain instances when the BLIS will alert with no object present when backing up. This is known as a false alert. Some level of false alerts are normal.
Circumstances that may cause a false alert when backing up are backing out of a garage, backing in to a parking space, and objects very close to the sensor. False alerts are temporary and self-correct.
