What is the role of my Toyota Verso glow plug light?

The main purpose of the engine glow plug light, which is in most cases represented by a yellow coil, is to assure that your glow plugs are working effectively. In reality, it must light up when you switch on your Toyota Verso to tell you that they are heating the intake air in your cylinders and must go out after a few minutes when the engine is running. This preheat light is therefore not meant to stay or come on while driving with your automobile. Nevertheless, if it turns on while driving, it may reveal several failures, we will try to describe the main ones.
