PTBA Trailer Target Sticker
WARNING: This page is about a different car, the 2020 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
The PTBA trailer target sticker is attached to the trailer during initial setup and used by the rear parking aid camera and IPMB to calculate the angles of the trailer based on the dimensions entered in the IPC.
Refer to the Owner's Literature (Pro Trailer Backup Assist™ Quick Start Guide) to find the detailed instructions on how to properly position the PTBA trailer target sticker on the trailer.
NOTE:
Additional stickers can be ordered through a Ford dealer parts department.
