What is That Horseshoe-Shaped Light on My Dash? And What Does It Mean When It Lights Up?
You may never notice that horseshoe-shaped light on your dash, that is, until it lights up. The exclamation point in its center is a clear sign you should pay attention to. The light is part of your tire pressure monitoring system (TPMS), and it's alerting you that the pressure is likely too low in one or more of your tires.
