Does anyone know what it is? It's a small square that doesnt have holes like the rest of the bottom grill. It actually pushes in and opens and behind it is a pipe. Sorry if it's a newb question but just wondering what it is.

 

Its the location of the place to screw in the towing hook.

 

so that pipe thing back there is where you'd screw in the towing hook?

 

yup.

 

really? i thought it was part of the technology package-preview braking, which is where the sensor is located?

 

The sensor for preview braking and the ICC is the rectangular opening on the driver side of the lower grille.

 

simple search..
