Last updated:
When the maintenance / service reminder appears on your Lexus RX (2015–2022) — the RX 450h hybrid or the petrol RX 200t/300 — you can clear it yourself after a service using the dashboard menu. No dealer needed.
Before You Start
Reset only after the service is done. Switch the ignition on, not READY (don’t press the brake when you press START).
Resetting the Reminder
- Switch the ignition on (not READY).
- Using the steering-wheel controls or the Remote Touch screen, open Setup / Settings > Vehicle > Maintenance (or ‘Scheduled Maintenance’).
- Select the engine oil / maintenance item and confirm the reset.
- The reminder clears and the interval restarts.
Some early cars also accept the trip-button method: switch on (not READY), select TRIP A, switch off, then hold the trip button while pressing START twice until the display shows ‘000000’.
If the Reminder Won’t Clear
- Stay in ignition-on, not READY — don’t press the brake.
- Confirm the reset when the menu prompts — backing out leaves it unchanged.
- A separate warning light? A fault stores a code — look it up on autodtcs.com.
