206 Roland Garros Headlight and Rain sensor

First of all, hello everyone, I own a Peugeot for about 4 months. There are features such as headlight sensor and rain sensor that I heard in the Roland garros series, but I could not activate it somehow. I somehow opened the rain sensor, the green light on the front came on, but it still does not work. Does anyone have a user manual or information about it, thanks in advance.

position of arm in auto position on wiper?

Yes, sir, it is in auto mode, but it does not react. I am making the sensor active, the light of the sensor is on.

Ustad I guess the rain sensor is not like that in fords or wws. You have to operate the wiper for once, then it connects it to the automatic. If I remember correctly, my 2003 model 307 XT was the same. I was running it myself once when it rained, then it continued. Same with my current car.
