    the Master Light does not come on for my 2008 toyota prius but sometimes comes on for my 2006 prius.

    If you see the red triangle briefly flash on start up, it means your 12 V battery is low. Check your 12 V battery and charge it up. If it fails to hold a charge, replace it.

    thank you very much for letting me to to test my 12 V battery. I just got the 2006 prius 2 weeks ago and I don't remember seeing the 12 volt battery changed in the pile of service records.
