How to Reset 2012 Prius Maintenance Light: A Quick Guide to Reset Your Maintenance Light in Just Minutes

The 2012 Toyota Prius features a maintenance required (“MAINT REQD”) light that appears to remind you of scheduled service, such as oil changes. Resetting this light is a simple process you can complete at home, typically after completing the required maintenance. Here’s how you can reset the maintenance light on your 2012 Prius:

1. Turn the ignition switch to “ON” (do not start the engine). If you have a push-button start, press the button once — with your foot off the brake.
2. Press the “Trip” or “Odometer/Trip” button until you display “TRIP A” on the dashboard.
3. Turn the ignition switch “OFF.”
4. While pressing and holding the “Trip” button, turn the ignition switch back to “ON.”
5. Keep holding the button. You’ll see the odometer display show some dashes (“_ _ _ _ _”), then zeros. Once the zeros appear, release the “Trip” button.
6. The maintenance light should be reset and no longer display when you start your Prius.

As a designer, I always appreciate a vehicle interface that’s intuitive and user-friendly. The Prius dashboard is simple and ergonomic. If you’re planning any upgrades to your garage or want to visualize how your Prius or other cars fit in, tools like a 3D Floor Planner let you easily experiment with vehicle placement and garage layout for seamless function and style in your home.

Tips 1:

If your maintenance light returns soon after resetting, double-check that your maintenance (such as an oil change) was performed correctly. Persistent issues may indicate a deeper problem that requires a certified mechanic’s attention.
