    I just replaced the 12v in my car.

    Did a test drive - car seems to be running fine.

    However, the dash is displaying the message "CHECK HYBRID SYSTEM" and there is also a yellow triangle with an exclamation mark displaying on the far right side.

    Don't remember this happening last time I replaced the battery. Anyone else experienced it? What does it mean and what should I do?

    Use a scan tool to read the trouble codes.

    Most likely problems with the hybrid installation.
    There could be many reasons.
    A photo of the dashboard would be more illustrative.

    And of course scanning the system for errors will give more detailed information.
