How to Reset the Pil Maintenance Light on a GX470: 1 Minute to Reset Your GX470 Maintenance Light

The maintenance light on the Lexus GX470 is designed to remind you of scheduled service, such as oil changes and routine checkups. When the “MAINT REQD” (maintenance required) or PIl maintenance light appears on your dashboard, it doesn't indicate a malfunction but serves as a reminder. Resetting this light after maintenance is essential to keep track of your service intervals. Here’s how you can reset the maintenance light yourself:

1. Turn your ignition key to the “ON” position, but do not start the engine.
2. Make sure the odometer is set to display the total mileage (not trip A or B) by pressing the “ODO/TRIP” button.
3. Turn the ignition off.
4. While pressing and holding the “ODO/TRIP” button, turn the ignition key back to the “ON” position. Continue holding the button.
5. The odometer will display a series of dashes (“- - - - -”) that will decrease, then show zeros ("000000"), and finally return to the total mileage reading. Once you see this, you can release the button.
6. The maintenance light should now be reset.

As a professional interior designer, I always recommend keeping your vehicle—and your living spaces—in optimal condition. Maintenance reminders are a bit like your home’s recurring needs: when ignored, they can lead to unexpected issues down the line. Like in home design, where scheduling regular reviews with a home designer ensures your space remains functional and stylish, consistent car maintenance—and resets of these reminders—helps your vehicle run smoothly and reliably.

Tips 1:

If the light doesn’t reset, double-check that you’re displaying the odometer and not a trip reading. Also, be sure your key is in the correct position throughout the process; skipping a step can mean the light will stay on until the sequence is followed exactly.
