Thanks for all the silly input.
The catch is the lights!! The lights have to be on -- der!
At work I downloaded the owners manual for a 2005 as the '06 wasn't yet available online.
It says something like:
The headlight washers will activate with the winshield washers when the lights are on at reasonable intervals!
I have no idea what a reasonable interval is, but I can tell you that it does it the first time after you start up, but not the 2nd through 6th time within a few minutes. So, you have to restart the car to get it to work again quickly.
WE WERE AMAZED!!! We all thought the little square would crack open a bit a spray some water. Instead this R2D2 thing comes out of the bumber like 6 inches and sprays the headlights -- twice.
It is my new favorite feature. Of course, it sprays washer fluid all over your hood. It was worth it!
