Have Toyota Questions? Ask a Mechanic for Answers ASAP
Thanks for posting
There is a 12 volt battery located in the trunk, it's called the auxiliary battery, when these go below a certain voltage the hybrid computers stop communicating, I would highly recommend that you have this battery tested using a computerized tester, the hybrid 12 volt batteries are not the same as regular car 12 volt batteries and if it's the original battery it will most likely need replacing,.
Do you have any roadside assistance service or possibly a tow truck can try to jump start it for you.
