The second-generation Lexus RX (XU30) 2003-2008 was a hugely popular luxury crossover, the first to spawn the RX 400h petrol-electric hybrid alongside the V6 petrol models. Once serviced, the RX keeps showing its maintenance status until the electronics are reset. Owners most often use the oil service reset to clear the reminder and a service light reset after the full interval, with a TPMS reset handy after tyre work. On the 400h hybrid the 12V auxiliary battery, located in the boot, may need confirming after replacement. Use the guides below to find the correct reset for your XU30 RX.
