Tire Pressure Monitor Operation This vehicle may have a Tire Pressure Monitor System (TPMS). The TPMS is designed to warn the driver when a low tire pressure condition exists. If your vehicle has this feature, the TPMS sensors are mounted onto each tire and wheel assembly, excluding the spare tire and wheel assembly. The TPMS sensors monitor the air pressure in your vehicle's tires and transmit tire pressure readings to a receiver located in the vehicle. When a low tire pressure condition is detected, the TPMS illuminates the low tire pressure warning light on the instrument panel cluster. The low tire pressure warning light comes on at each ignition cycle until the tires are inflated to the correct inflation pressure. 5-60
