Renault Trafic 3 Emergency braking system

Hello, I actually drive a Nissan Primastar Tekna 2023, but is identical to the Renault Trafic 3 from 2022. I miss the emergency braking system. The Tekna equipment should have it ex factory according to chassis number is also installed, only seen or at least the warning in the cockpit what should appear according to manual or intervene missing any track. Due to quite provoking or even 2 times almost accident I have never seen the system after almost 20000km. Neither warning nor intervention. r Bus is now standing at the Nissan/Renault dealer has both is in contact with Nissan and Renault. According to him, the system is definitely installed and should work. What is it like with you? Ever seen at least once the warning in the cockpit? Would I be very pleased about information
