Megane 250 Xenon Auto Leveling Sensor Location

Hi, my Megane is pointing just few meters in front of the car, I suspect its the self leveling sensor, car is equipped with xenon. I cant find anywhere on the Internet what is the location of that sensor (looks like 3 arms). And is ther eonly one sensor ? front or rear? or 2 sensor, both in front and rear? Thank you very much for help.
