To reset the low tyre pressure light on the Lexus RX, first ensure that all tyres are inflated correctly to the pressure specified for your model, preferably with 'cold' tyres. Secure the vehicle, turn on the ignition, and access the onboard system from the central display.

Enter the vehicle settings menu and navigate to the section dedicated to tyres/TPMS. From here, select the reset/initialisation function for the pressure and confirm when the warning appears. The system will start storing the new reference and, depending on the configuration, may require a short drive to complete the learning process.

If the warning reappears quickly after the reset, do not persist with further resets: check the pressures, look for possible slow leaks, and ensure that any sensors/valves are functioning correctly. The reset clears the reference but does not resolve the underlying cause that triggered the warning.
