The first-generation Lexus RX (XU10) 1998-2003 effectively created the luxury crossover, blending Camry-derived V6 reliability with raised, car-like comfort. Its body computer and engine ECU still need attention after servicing. Once the oil and filter are renewed the maintenance light must be reset from the dash so the interval counter restarts. Brake servicing calls for a pad wear reset, while a new 12V battery should be followed by a battery reset to restore correct charging logic. If the automatic windows lose their memory the electric window initialization re-teaches the limits, and the steering angle sensor may require zeroing after suspension or steering work. Select the appropriate reset procedure for your RX from the list provided below.
