That little “Maintenance Required” light on your dashboard can be a real source of anxiety. Is your car about to explode? Probably not. But it’s definitely trying to tell you something. This article provides a complete guide on how to understand and reset the “Maintenance Required” light, ensuring you stay on top of your vehicle’s needs and avoid unnecessary worry.
Understanding the “Maintenance Required” Light
The “Maintenance Required” light is not the same as the “Check Engine” light. While both can be alarming, they signal different things. The “Check Engine” light usually indicates a problem with your engine or emissions system, requiring immediate attention from a mechanic. The “Maintenance Required” light, on the other hand, is a reminder that your vehicle is due for scheduled maintenance, like an oil change or tire rotation.
What Triggers the Light?
The “Maintenance Required” light is typically triggered by a mileage-based or time-based interval. Your car’s computer is programmed to illuminate the light after a certain number of miles have been driven since the last reset, or after a certain amount of time has passed. This interval is pre-set by the manufacturer and is intended to coincide with the recommended service schedule outlined in your owner’s manual. Ignoring this light doesn’t necessarily mean immediate catastrophic failure, but neglecting scheduled maintenance can lead to more significant problems down the road.
Why is it Important to Address?
Even though it’s not an emergency signal, it’s crucial to address the “Maintenance Required” light promptly. Delaying scheduled maintenance can lead to reduced fuel efficiency, decreased performance, and potentially more expensive repairs in the future. Imagine neglecting an oil change – old oil can become sludgy, hindering lubrication and causing engine wear. By staying on top of your maintenance schedule, you ensure your vehicle runs smoothly and efficiently for years to come.

Why is my “Maintenance Required” light on even after an oil change?
The “Maintenance Required” light is often a timer or mileage-based reminder, not necessarily directly tied to the actual completion of maintenance. It’s programmed to illuminate after a predetermined interval to prompt you to schedule routine servicing, primarily an oil change. Even if you have just had an oil change, the light will remain on until the system is manually reset, indicating that the service has been performed.
Resetting the light is typically a separate process from the oil change itself. Mechanics may forget to reset it, or they might assume you’ll handle it yourself. Check your vehicle’s owner’s manual for the specific reset procedure, as it varies between makes and models. Common methods involve using the trip odometer button or a combination of ignition key positions and pedal presses.
What happens if I ignore the “Maintenance Required” light?
Ignoring the “Maintenance Required” light won’t immediately cause your car to break down, but it’s generally not a good practice. The light serves as a reminder for essential services, primarily oil changes, which are crucial for maintaining engine health and longevity. Overlooking regular maintenance can lead to decreased fuel efficiency, increased engine wear, and potentially costly repairs down the road.
While the light is often tied to the oil change interval, it might also coincide with other recommended maintenance tasks like tire rotations, fluid checks, or filter replacements. Consulting your owner’s manual’s maintenance schedule will provide a comprehensive list of required services and their intervals. Ignoring the light for extended periods could lead to overlooking these other essential services, compromising your vehicle’s performance and reliability.
Is the “Maintenance Required” light the same as the “Check Engine” light?
No, the “Maintenance Required” light and the “Check Engine” light are distinct indicators with different purposes. The “Maintenance Required” light is a scheduled service reminder, typically linked to mileage or time intervals to prompt routine maintenance, primarily oil changes. It’s a proactive reminder to keep your car running smoothly.
The “Check Engine” light, on the other hand, indicates a problem with your vehicle’s engine or emissions system. It signals that something is malfunctioning and requires immediate attention. Ignoring the “Check Engine” light could lead to more serious engine damage and potentially costly repairs. It often requires a diagnostic scan to identify the underlying issue.
How do I find the correct reset procedure for my car’s “Maintenance Required” light?
The most reliable source for finding the correct reset procedure is your vehicle’s owner’s manual.

Alternatively, online forums or YouTube tutorials specific to your vehicle model can provide visual guidance and alternative solutions if the manual’s instructions are unclear.
Can a faulty sensor cause the “Maintenance Required” light to come on?
While the “Maintenance Required” light is primarily triggered by a timer or mileage counter, a faulty sensor is unlikely to directly cause it to illuminate. The system is designed to alert you based on predetermined intervals, not real-time sensor readings. The light is more of a proactive reminder than a reactive warning.
However, a malfunctioning sensor could indirectly contribute to the light coming on if it prevents the reset procedure from working correctly. If you’ve followed the correct reset procedure from your owner’s manual multiple times and the light persists, it’s possible there’s an underlying electrical or sensor issue interfering with the system. In this case, a diagnostic scan by a qualified mechanic is recommended to identify and resolve the problem.
Will resetting the “Maintenance Required” light affect my car’s performance?
Resetting the “Maintenance Required” light itself will not directly affect your car’s performance. The reset simply clears the reminder and doesn’t alter any engine settings or vehicle parameters. It’s essentially turning off a visual notification.
However, it’s important to remember that the light serves as a reminder for essential maintenance. If you reset the light without actually performing the necessary maintenance, such as an oil change, your car’s performance could eventually be negatively impacted. Regular maintenance is crucial for maintaining optimal engine health and efficiency.
Is it okay to drive my car with the “Maintenance Required” light on?
Driving with the “Maintenance Required” light on is generally safe, as long as you are confident that your vehicle is otherwise functioning properly. The light primarily serves as a reminder for scheduled maintenance and doesn’t necessarily indicate an immediate mechanical problem. It is usually triggered based on mileage or time intervals.
However, it’s crucial to ensure you are up-to-date with all recommended maintenance services. Delaying necessary maintenance can lead to increased wear and tear on your vehicle and potentially more costly repairs in the long run. If you’re unsure when your last service was, consult your owner’s manual or maintenance records to determine if it’s time for an oil change or other scheduled services.
