1. Turn the ignition key to the "ON" position (do not start the vehicle).
2. Locate the trip reset button on the dashboard, typically near the speedometer.
3. Press and hold the trip reset button for five seconds.
4. While holding the reset button, turn the ignition key to the "OFF" position and then back to the "ON" position (again, do not start the vehicle).
5. Release the reset button. The maintenance light should now be reset.
If the maintenance light does not reset or if it comes back on again shortly after reset, there may be an underlying issue with the vehicle that needs to be addressed. In this case, it's best to take the vehicle to a qualified mechanic for further diagnosis and repair.
