After under wash, this came (it says check hybrid system) when I tried to start for 2nd time after abt 5km drive. After few attempts it was fail safe drive with no eco full time engine, ⚠ sign on with this message. It went away after my next stop in abt 30 mins. On my way to Colombo from Kandy it did abt 30.5km/l and fully normal. So I think its temporary? Wat do you think?
You probably got water where water isn't suppose to go. Since it's normal now......the problem is solved.
Thanks everyone for the comments. @JC it's revealing when you also say that. I got really panicked when I see this message in Japanese. because its a domestic model. Got a friend to translate it... I hope now it's fine. But good to know that there is a emergency mode, so I will not get busted in middle of the road. Should I do a check with Toyota or not worry further..
