CTA False Alerts

CTA False Alerts  - Blind spot information system (blis ) with cross traffic alert (cta) (if 
equipped) - Driving - Lincoln MKZ Owners Manual - Lincoln MKZ

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.
