Resetting the maintenance light on a 2021 Toyota Highlander is a straightforward process that can be done in just a few steps. Below, I will outline the symptoms, diagnostic steps, tools required, and the detailed instructions to reset the maintenance light.

Tools Required

No special tools are required for this process. Just your vehicle's key or key fob.

Reset Instructions

Step 1: Turn the Ignition On

Enter the Vehicle: Sit in the driver’s seat and close all doors.
Insert the Key: If your Highlander uses a traditional key, insert it into the ignition. If it uses a key fob, ensure it is inside the vehicle.
Turn Ignition to ON: Turn the ignition switch to the "ON" position without starting the engine. If your Highlander has a push-button start, press the "Start" button twice without pressing the brake pedal.

Step 2: Access the Multi-Information Display (MID)

Locate the Odometer Button: Find the odometer trip button on the dashboard, typically located near the speedometer.
Press and Hold the Odometer Button: Press and hold the odometer trip button until the display shows "Trip A".

Step 3: Reset the Maintenance Light

Turn Off the Ignition: While still holding the odometer button, turn the ignition switch to the "OFF" position.
Continue Holding the Odometer Button: Keep holding the odometer button for about 10 seconds.
Release the Odometer Button: After 10 seconds, release the odometer button.
Turn Ignition On Again: Turn the ignition back to the "ON" position without starting the engine.
Check for Maintenance Light: The maintenance light should now be reset, and you should see a confirmation message on the display indicating that the reset was successful.

Step 4: Verify Reset

Start the Engine: Start the vehicle to ensure that the maintenance light is no longer illuminated.
Check Dashboard: Confirm that the maintenance light is off. If it remains on, repeat the reset steps.

Conclusion

Following these steps should successfully reset the maintenance light on your 2021 Toyota Highlander. If the light persists after attempting to reset, it may indicate an existing issue that requires further diagnostics and inspection. Always refer to the owner’s manual for specific vehicle information and maintenance schedules.
