START STOP PROBLEM

I changed the battery of my car 2016-308-Classic Edition Plus just last week. When my car stops at the light, etc., the start stop comes on, it stops, but when I give the gas, it doesn't work. Can I find out why and does anyone have a solution?

Hello teacher. welcome aboard. In battery changes, the system may not be activated immediately, it takes a certain time, sir. First of all, have the vehicle checked by a workshop that has the original diagnostic device. Check the battery voltage and charge voltage values.
