We’ve had one for two weeks now. The manual is already a book. A lot is unnecessary. It also has a tracking warning system and a front collision avoidance system in the basic version. But unfortunately, either I don’t find it, or I don’t get it, the FCM doesn’t get turned on. For a long time press on the said switch, either the small light is on (FCM off) or no display at all. Then you can set the distance (wide, medium, close). wanted to test the function with a friend. It does not slow down. Does this only work with the cruise control switched on or what do I not understand? In the operating instructions only, press the switch for a long time to switch off or on. Christian
