What Does an Illuminated Tire Pressure Monitoring Indicator Light Mean?

Eliminate uncertainty about tire pressure - and, in turn, eliminate many serious accidents - by promptly addressing your vehicle's tire pressure monitoring system (TPMS). When the TPMS indicator light illuminates, it means that at least one tire is significantly under-inflated. Improperly inflated tires negatively affects the traction, stability, braking, and steering of your vehicle. Gas mileage can decrease, and the lifespan of all four tires can be shortened due to uneven tire wear.

The yellow TPMS light resembles a horseshoe. However, what it's really shaped like is the cross-section of a tire with an exclamation point. Without frequent manual pressure checks, many Middleton, Fitchburg and Verona, WI area drivers will see this warning light at some point, as pothole damage and frigid temperatures both affect tire pressure.
