Read guideYour dashboard lit up and you have no idea what it means. This is where you find out. Warning Lights and Symbols is our running dictionary of driver-assist alerts, from the flashing lane-keep icon to the amber car-with-waves collision symbol and the plain-text radar blocked message. Each guide shows you what the light looks like, which system it belongs to, why it came on, and how serious it is. You will learn the difference between a warning that clears itself after a wash and one that means a sensor has genuinely failed. We keep the language plain, skip the manual jargon, and tell you when a light is safe to drive with and when it is worth pulling over. Start here when you need a name for the thing glowing at you.
