Hello and welcome to JustAnswer!

Warning lights will come on either when a module isn't communicating with the instrument cluster or a module has seen a problem somewhere in it's monitored components/system and sets a fault code. It's possible that you could have one or more fuses blown, there may be modules that are internally damaged, or there may be multiple unrelated problems in different systems. I have to wonder if polarity was reversed at some point.

Have fuses been checked?

What specific warning lights are on?

Customer: replied 1 year ago.
Wow! Thanks for answering
I forgot the fuses. Tomorrow morning I will check all of them. I'm not a mechanic, but I'm an electronic technician.
Another question. The car has already 248,216 miles. Do I need to change the hybrid oil? (Oil of the electric motor)
I think is good to take it to the dealer for a diagnostic.
The car runs like new, but all warning lights are on
Thank You again

I'm not showing any transmission fluid changes called out in the service intervals but at that high mileage it definitely wouldn't be a bad idea.
