Tow Bar Not Locked
These are Tow Bar Not Locked Indicator symbols. If equipped, the indicator will be seen if a towed vehicle is not properly connected to the tow bar. The symbols are seen as a hooked rod or bar with a ball shape at the high end, one adding a padlock, and one showing the back of a vehicle with the ball sticking out and an exclamation point, all but one in yellow/amber/orange.

The image with arrows above the trailer is no more than a Trailer Connected indicator. It illuminates when a trailer is connected and will go out when it is disconnected. The same is true of the image of the trailer hitch ball and the trailer, both shown in 
These versions however, are trailering fault warnings. The exclamation point in the triangle above the trailer in the first image is the give away. If illuminated, check all electrical connections as well as the physical trailer connection(s). Otherwise, the issue may involve the main vehicle’s suspension or stability control systems and a qualified service shop will be needed.
Some vehicles offer Sway Control for use while towing, a system that works in in conjunction with the Stability Control System. And like that system, the Sway Control Indicator will flash when sway is detected and being corrected.
