Tire Pressure Monitoring System (TPMS)
Since an under-inflated tire impedes handling and can be a safety hazard, the Tire Pressure Monitoring System (TPMS) uses pressure sensors mounted in each wheel that send readings to a central electronic control unit. The system then evaluates whether the pressure is up to an acceptable range. If a reading is approximately 25% below the recommended level, the RDX will alert the driver through the Multi-Information Display (MID) located on the instrument panel. The problem tire will be indicated, along with the individual pressure, for all four tires. The pressure display can be accessed any time, using the MID controls on the steering wheel.
