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 RLX will alert the driver through the Multi-Information Display (MID) located on the instrument panel.
- The under-inflated tire will be indicated, along with the individual pressure, for all four tires.
- The pressure display can be accessed anytime using the MID controls on the steering wheel.
- As useful as TPMS is, it is still recommended that you manually check your tires on a regular basis.
