The illumination of a specific indicator within a Toyota Highlander’s instrument cluster signifies a deviation from the recommended tire inflation levels. This visual signal alerts the operator to a potential under- or over-inflation scenario affecting one or more tires. For instance, if ambient temperatures drop significantly, the pressure within the tires may decrease, triggering the warning.
Maintaining proper inflation is paramount for optimal vehicle performance, fuel efficiency, and tire longevity. Historically, drivers relied on manual gauges and periodic checks to ensure correct pressure. The introduction of these automated systems provides a real-time monitoring capability, enhancing safety and minimizing the risk of tire-related incidents. This feature allows for prompt corrective action, preventing premature tire wear and potentially dangerous handling characteristics.
