The direct Tire Pressure Monitor System in the RX 450h constantly monitors the air pressure of all tires, including the spare. When it senses that tire pressure is critically low, it alerts the driver with an indicator light.
The Tire Pressure Monitor System alerts the driver when tire pressure is critically low. For optimal tire wear and performance, tire pressure should be checked regularly with a gauge; do not rely solely on the monitor system. Please see your Owner's Manual for details.Back to top
