Added E-85 gas by mistake

[packratmag]

I accidentally put E-85 gas about 1/2 tank in my 2013 ES-350.  The check engine light came on and Trac off light.What do I do? Can I siphon out the gas or is there an anti-theft in the tank? How do I do it?  Can I top the tank off with regular gas? or will that harm the fuel pump, gas lines, etc.  I'm so embarrased !!!!

What I'd do if the car still runs, and it probably does,  is top it off with regular non-gas a hol (pure gasoline).  You can find it around there, and go for a long long ride to burn it off the alcohol quick.  Got any friends in Texas?

You want to burn off the alcohol as fast as possible before it has a chance to do harm to the fuel system.

If your owner's manual does not specifically state that your engine can use E85, then either have it siphoned out or try Lex Lex's suggestion about filling up the tank with non-E85 gas and use it up as soon as you can.
