The dreaded “Maintenance Required” light. It’s a common sight on dashboards, often appearing to remind us about upcoming oil changes and routine vehicle service. But what happens when you diligently get your oil changed, only to find that pesky light still shining bright? It can be frustrating, confusing, and leave you wondering if something went wrong. Rest assured, in most cases, it’s a simple issue, but it’s crucial to understand the underlying reasons and how to address it correctly.
Understanding the Maintenance Required Light
This light isn’t always directly tied to your oil level or oil quality sensor. It’s more of a general service reminder system that operates on a pre-programmed interval based on mileage or time. Modern vehicles are equipped with sophisticated onboard computers, but the maintenance required light is typically a simpler, less complex system than, say, an oil life monitoring system found on some newer models.
The Purpose of the Light
The primary function of the maintenance required light is to prompt you to bring your vehicle in for routine checkups and preventative maintenance. This could include oil changes, tire rotations, fluid checks, filter replacements, and other essential services necessary to keep your car running smoothly and reliably. Automakers set these intervals based on what they deem to be best practices for maintaining optimal performance and preventing potential problems down the road.
Maintenance Required vs. Check Engine Light
It is extremely important to differentiate between the “Maintenance Required” light and the “Check Engine” light. The “Maintenance Required” light, as the name implies, is simply a reminder. The “Check Engine” light, on the other hand, indicates a problem with your engine or emissions system and requires immediate attention. Ignoring a “Check Engine” light could lead to more serious and costly repairs. A solid “Check Engine” light means the issue is present. A flashing “Check Engine” light is an urgent warning and suggests a severe problem that could cause immediate damage to your engine.
The Resetting Process: What Should Have Happened
When you get an oil change, the technician should reset the maintenance required light as part of the service. This tells the car’s computer that the service has been performed, and the timer for the next reminder should begin. The reset procedure varies depending on the vehicle’s make and model, but it usually involves a sequence of steps using the ignition key, the trip odometer reset button, or the information display controls on the steering wheel.
Why the Light Wasn’t Reset
Several reasons could explain why the maintenance required light wasn’t reset after your oil change:
- Technician Error: The most common reason is simply human error. The technician may have simply forgotten to reset the light. It’s a routine task, and sometimes, especially during busy periods, it can be overlooked.
- Lack of Awareness: In some cases, especially with older vehicles or less experienced technicians, the proper reset procedure for your specific vehicle may not be known. Vehicles have different procedures, and keeping up with all of them can be a challenge.
- Communication Breakdown: Sometimes, even if the technician attempts to reset the light, the car’s system might not respond correctly due to a glitch or an intermittent problem.
- Intentional Omission: Though less common, some service centers might intentionally leave the light on as a way to encourage you to return to their shop for future services. This is unethical but can occur.
Consequences of Ignoring the Maintenance Required Light
While the maintenance required light is primarily a reminder, ignoring it for extended periods isn’t advisable.
- Missed Services: You might forget about other essential maintenance tasks that are due, potentially leading to neglected components and premature wear.
- Reduced Resale Value: A consistent history of neglecting maintenance can negatively impact your car’s resale value. Potential buyers will be wary of a vehicle that hasn’t been properly cared for.
- Potential for Larger Problems: While the light itself isn’t directly linked to a specific mechanical issue, ignoring scheduled maintenance can allow minor problems to escalate into major repairs.
How to Reset the Maintenance Required Light Yourself
Fortunately, in many cases, you can reset the maintenance required light yourself. However, it is critical to consult your owner’s manual for the specific procedure for your vehicle’s make, model, and year. Incorrectly attempting to reset the light could potentially cause other issues with your car’s electronic systems. Here are some general methods, but remember these are just examples, and your vehicle’s procedure may be different.
Common Reset Methods
- Trip Odometer Method: This involves turning the ignition on (but not starting the engine), pressing and holding the trip odometer reset button while turning the ignition off and then on again.
- Information Display Method: Some vehicles allow you to navigate through the information display menu on the steering wheel to find a “Maintenance Reset” option.
- Accelerator Pedal Method: Certain makes and models may require a sequence of pressing the accelerator pedal and turning the ignition on and off.
- OBD-II Scanner Method: An OBD-II scanner, which can read and clear diagnostic trouble codes, can sometimes also be used to reset the maintenance required light.

Communicate Clearly with Technicians
Clearly communicate your concerns and expectations with the technicians performing the service. If you have any questions about the maintenance required light or the reset procedure, don’t hesitate to ask.
Consider an Oil Life Monitoring System
If your vehicle is equipped with an oil life monitoring system, pay attention to its recommendations. These systems use algorithms to estimate the remaining oil life based on your driving habits and conditions, providing a more accurate indication of when an oil change is needed. However, these systems require proper resetting after each oil change to function correctly.
Why didn’t the mechanic reset my maintenance light after the oil change?
It’s possible the mechanic simply forgot to reset the maintenance required light after completing the oil change. While a standard part of the service for most shops, oversights can happen, especially during busy periods. Also, some older vehicles require a more complex reset procedure that might be overlooked if the mechanic isn’t familiar with the specific model.
Another possibility is a miscommunication. Perhaps you assumed the reset was included in the oil change service, but it wasn’t explicitly stated or agreed upon. To avoid this in the future, it’s always a good idea to confirm with the service advisor that resetting the maintenance light is part of the oil change procedure before leaving the shop.
How do I reset the maintenance required light myself?
The reset procedure varies depending on the make and model of your vehicle. Generally, it involves using the ignition key and dashboard buttons to navigate through a menu. A common method involves turning the ignition on (but not starting the engine), then pressing and holding the trip reset button while turning the ignition off and on again.
To find the exact instructions for your specific car, consult your owner’s manual. Many online resources, including YouTube videos and manufacturer websites, also provide step-by-step guides for resetting the maintenance light. Always follow the instructions carefully to avoid accidentally changing other vehicle settings.
Could there be something else wrong with my car if the light is still on?
While the maintenance required light typically indicates an oil change is due, it can sometimes be linked to other scheduled maintenance items or serve as a general reminder system. If the light persists after you’ve reset it, or if it comes back on soon after resetting, it’s worth investigating further.
It’s possible that other maintenance services are overdue, such as tire rotations, air filter replacements, or fluid checks. A diagnostic scan can help identify any underlying issues that might be triggering the light. Consulting with a qualified mechanic is recommended to rule out any potential problems and ensure your vehicle is running properly.
Is it okay to ignore the maintenance required light?
Ignoring the maintenance required light isn’t advisable. While it might seem like a minor issue, the light serves as a reminder for essential maintenance tasks that help ensure your vehicle’s longevity and performance. Neglecting these tasks can lead to more significant problems down the road.
Delaying necessary maintenance can result in decreased fuel efficiency, reduced engine performance, and even potential damage to critical components. Addressing maintenance needs promptly helps maintain your vehicle’s reliability, safety, and resale value. Therefore, it’s best to address the light as soon as possible.
Will the maintenance required light affect my car’s performance?
The maintenance required light itself doesn’t directly affect your car’s performance. It’s simply a reminder system. However, the underlying issues that the light is meant to address can definitely impact performance if left unattended.
For example, if the light is on due to overdue oil change, continued use of old oil can lead to increased engine wear, reduced lubrication, and potential engine damage. This can result in decreased fuel economy, sluggish acceleration, and ultimately, more expensive repairs. Keeping up with maintenance is crucial for optimal performance.
How often should I change my oil to avoid this issue in the future?
The recommended oil change interval varies depending on your vehicle’s make, model, and engine type, as well as the type of oil used. Consult your owner’s manual for the manufacturer’s recommended oil change schedule. Typically, older vehicles require oil changes every 3,000 miles, while newer vehicles using synthetic oil can often go 5,000 to 7,500 miles or even longer.
Consider your driving habits when determining your oil change frequency. If you frequently drive in stop-and-go traffic, tow heavy loads, or operate in extreme temperatures, you may need to change your oil more frequently than the recommended interval. Regular oil changes are essential for maintaining engine health and preventing premature wear.
What’s the difference between the maintenance required light and the check engine light?
The maintenance required light is a reminder for routine maintenance services, primarily oil changes, but it can also be programmed to indicate other scheduled maintenance. It’s a proactive notification to keep your car in good working order and prevent potential problems.
The check engine light, on the other hand, indicates a more serious issue with your vehicle’s engine or emissions system. This light is triggered by a sensor detecting a malfunction and requires immediate attention to diagnose and repair the underlying problem. A check engine light should never be ignored, as it could signal a significant mechanical or electrical issue.
