The illumination of an indicator on the dashboard of a Toyota RAV4, shaped like a horseshoe or low-pressure tire with an exclamation point inside, signals a deviation from the recommended inflation level within one or more of the vehicle’s tires. This alert is triggered by the Tire Pressure Monitoring System (TPMS), a safety feature designed to help maintain proper tire inflation. For example, if cold weather causes a drop in tire pressure, or a slow leak occurs, the system detects this change and activates the warning.
Maintaining correct tire inflation is crucial for several reasons. It optimizes fuel efficiency, as under-inflated tires increase rolling resistance. Proper inflation also extends tire lifespan by promoting even wear and maximizing grip, which enhances vehicle handling and braking performance. Furthermore, correctly inflated tires contribute to overall safety, reducing the risk of tire failure and accidents. The development and implementation of tire pressure monitoring systems represent a significant advancement in automotive safety technology, providing drivers with real-time information and prompting them to address potentially dangerous conditions.
