Hello, that model uses two batteries: one in the engine bay and another under the passenger's feet, both of 170 Ah. They tend to fail frequently, causing issues with the start-stop system.
To verify if the battery is in good condition, you need a **battery test with a specialized device**—a simple tester is not enough. If the batteries are fine, other factors can also affect the system, such as **not wearing the seatbelt, low fuel level, or low vehicle temperature**.
From my experience, the issue is usually the batteries. If you have any doubts, feel free to write to me. I can send you pictures of the battery testing equipment and the location of the secondary battery.
