What does the green dashboard symbol mean on a Toyota vios 2008? When you start the car, this symbol is lighted. After 5 minutes it goes off. I'm guessing this indicates that the engine is still cool and warming up. Should I wait for this to go off before I drive the car? Or no need to wait for this?
The symbol looks like a pole with three flags, and the word "COOL" at the bottom of it, all are in the color green.
