CTA false alerts

CTA false alerts  - Blind spot information system (BLIS ) With crosstraffic alert (CTA) (If 
equipped) - Driving - Lincoln MKS Owners Manual - Lincoln MKS

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 into a parking space, and objects very close to the sensor. False alerts are temporary and self correct.
