How to Reset Maintenance Light in a 2012 Prius: Quick and Easy Steps to Save You Time

The maintenance light in your 2012 Prius is a helpful reminder to perform regular oil changes and other routine services. However, after you've completed the necessary maintenance, you'll want to reset this light to keep your dashboard clear and ensure accurate reminders for the next interval. Here’s a step-by-step guide to resetting the maintenance light in a 2012 Toyota Prius:

1. Turn the car's ignition to the "ON" position (do not start the engine).
2. Press the “Trip” button on your dashboard, usually located near the odometer, until the display reads “TRIP A.”
3. Turn the ignition OFF.
4. While holding down the “Trip” button, turn the ignition back to the “ON” position (again, do not start the engine).
5. Continue holding the “Trip” button. The odometer will display a series of dashes (“---”), then zeroes (“000000”), and finally the normal odometer reading, indicating that the reset is complete.
6. Release the “Trip” button. The maintenance required light should now be off.

In both interiors and vehicles, details matter! If you’re interested in bringing the same sense of order and personalization to your home as you do to your vehicle, exploring creative tools like home designer software can help you visualize, plan, and execute your perfect space.
