Disclosed is a system comprising a vehicle, a trailer, and a display screen. The system includes a trailer angle between a centerline of the vehicle and a centerline of the trailer. At least one time step after the vehicle is driven backward such that the trailer angle increases beyond a threshold value, a steering warning icon is displayed on the display screen. When the trailer angle decreases below the threshold value, the steering warning icon is removed from the display screen.

In an embodiment, a vehicle makes a determination, during a second ignition-on cycle of the vehicle, that a trailer brake output circuit of the vehicle was operated during a first ignition-on cycle of the vehicle preceding the second ignition-on cycle. In response to making the determination, the vehicle presents a query, via a user interface of the vehicle, whether to operate the trailer brake output circuit according to a previously-used trailer profile according to which the trailer brake output circuit was operated during the first ignition-on cycle preceding the second ignition-on cycle. The vehicle receives a reply, associated with the query, via the user interface and, in response to receiving the reply, operates the trailer brake output circuit based on the reply.
