The first-generation Lexus IS Mk1 (XE10) 1999-2005, sold as the Toyota Altezza in Japan, was a compact rear-drive sports saloon with the rev-happy 2.0 inline-six and the later 3.0 inline-six. After servicing, this early IS keeps its maintenance reminder showing until reset. The main jobs owners perform are the oil service reset to clear the indicator and a service reminder reset once the full interval is complete. With relatively simple electronics, the reset is usually a quick dash or trip-stalk sequence. Browse the guides below and choose the one matching the work done on your XE10 IS.
