'16 EX LTD body/bumper question

[tysoneric]

Does anyone know what the small almost circular "compartment door" is for, located on passenger side of front bumper? about 2 inches in diameter with an arrow head (line up) mark on it, pointing to 2 o'clock position.
Tried to add pic, but maybe I'm not at that level yet on forum

That is where you would install your tow hook that is stored with the tire jack. It comes with all 4x4's.
