One of the things you will notice when you turn on your ignition is the different car symbol lights on the dashboard. Most of these lights are supposed to turn off as soon as you start the engine. But if any of the lights stay on or reappear after the engine starts, it is trying to notify you of an issue.
The color of the dashboard light determines what it is trying to tell you. For example, a red light on the dashboard means a severe issue that needs urgent attention. Yellow or amber light signifies a mild or less severe issue. White and green lights show the system is currently in use or working correctly. This article will explain what blue light on the dashboard means and how to clear it.
