What Does The Tire Pressure Light Mean?
There’s a horseshoe-shaped warning light on your car's dashboard with an exclamation point in the middle. This is your tire pressure light, also known as the TPMS light.
TPMS is short for Tire Pressure Monitoring System. You can find this system on all modern passenger vehicles, and it consists of a set of sensors on each tire, connected to a central computer. When the pressure on one or more tires drops too low, the computer will register the drop, and the warning light will come on.
But what does this mean for you, the driver? Let’s talk about what the tire pressure light means and what you should do when it lights up.
