What to do when the red triangle light comes on on Toyota Prius?
Years 2009-2015

Answer

The turning on of the warning light in the shape of a triangle with the exclamation point indicates that there is a generic type of engine failure and, consequently, a diagnosis is required. This warning light can be presented in two colours: yellow or red. In the first case you can complete the journey you are making and then check the damage, while in the second case you must stop the vehicle immediately.
