The fourth-generation Lexus RX Mk4 (AL20) 2015-2022 sharpened the styling with its spindle grille and floating roof, offering the RX 350 V6 and the RX 450h hybrid. Its modules expect acknowledgement after most servicing. After an oil change the maintenance light is reset to restart the interval, and a TPMS reset addresses tyre pressure changes. The brake pad wear reset follows new pads, while the 12V battery, located in the boot on hybrids, should prompt a battery reset so the energy system reads its charge. Steering angle calibration is run after alignment, and electric window initialization re-teaches the glass. Select the relevant procedure for your RX from the list shown below.
