Tire Pressure Monitor Operation The Tire Pressure Monitor System (TPMS), if your vehicle has this feature, is designed to warn the driver when a low tire pressure condition exists. TPMS sensors are mounted onto each tire and wheel assembly, excluding the spare tire and wheel assembly.

When a low tire pressure condition is detected, the TPMS will illuminate the low tire pressure warning symbol located on the instrument panel cluster. 5-79
