    You are most likely going to need to find a way to read the trouble codes to get additional help. Those lights won't come on unless the ECU sees a problem, but with out addition information it could be a whole lot of things.

    Thank you for your reply. That's my fear, ECU has identified a problem. Today morning, I have restarted again the car. Now it shows only two indicators - Yellow malfunction, and car hybrid battery (Car with "!" mark). What the things altogether means?

    I like to give one update about my Prius C. I have contacted local service center of Toyota. They just reset ECU and it is working fine. Today all is working perfectly well. I got 20km/lt.

    As I wrote,Toyota service center has reset ECU and at that moment it was operating perfectly. But unfortunately, Got same problem after one day. This time I disconnected 12v battery and reconnect again. Problem solved, I thought. But getting same problem again. Shows two icon - Malfunction, car traction battery problem. I bought this old car from a dealer.

    As you now see, clearing the codes doesn't fix the problem. The next time the lights come (and they will) get them read and post them here so we can offer some informed opinions.

    The light is yellow indicators - Cars battery problem (Car with"!") and Malfunction problem. In the previous record of Toyota service center, it was recommended to change Battery Voltage Sensor which my previous car owner did not. Is that High voltage main battery sensor?
