CTA detection zones:
WARNING: This page is about a different car, the 2018 Lincoln MKC. However, it is still accessible from the selected car via links, so may be relevant.
The CTA system is designed to detect any objects approaching the vehicle at a speed equal to or greater than 8 km/h (5 mph). This includes vehicles and bicycles. The CTA system has some detection limitations due to the nature of the radar technology used by the SODL and SODR.
NOTE:
The CTA system is not intended to detect parked vehicles, pedestrians, animals or objects such as fences, guard rails or trees.
NOTE:
There should be no bumper stickers or body filler material used on the rear side bumper cover in the vicinity of the SODL or SODR.
