The “Maint Reqd” light, short for “Maintenance Required,” is a common sight on many car dashboards. It’s a friendly reminder from your vehicle’s computer system that a scheduled maintenance task is due. While it’s not usually indicative of a serious problem, ignoring it can lead to neglected maintenance and potentially more significant issues down the line. This guide will walk you through understanding this light, why it appears, and how to reset it properly for various car models.
Understanding the Maintenance Required Light
The maintenance required light is a programmed indicator, typically linked to your car’s odometer. It’s designed to illuminate after a certain number of miles have been driven since the last reset, prompting you to perform routine maintenance like oil changes, tire rotations, and filter replacements. It’s crucial to differentiate this light from the “Check Engine” light, which signals a potentially more serious problem with your engine or emissions system.
The appearance of the “Maint Reqd” light doesn’t necessarily mean your car is about to break down. It simply means that the car’s computer believes it’s time for scheduled maintenance based on mileage. However, neglecting this maintenance can invalidate warranties or lead to long-term damage.
Ignoring the “Maint Reqd” light can have several negative consequences. First, you might forget to perform essential maintenance tasks, leading to decreased vehicle performance, reduced fuel efficiency, and potentially expensive repairs. Second, if your car is still under warranty, failing to adhere to the recommended maintenance schedule could void your warranty coverage.
Why is the Maint Reqd Light On?
The most common reason the “Maint Reqd” light illuminates is simply that your car has reached the mileage interval programmed into its computer. This interval is typically set by the manufacturer and is based on the recommended maintenance schedule outlined in your owner’s manual. The distance for maintenance is around 5,000 to 7,500 miles, although that is just an average. Always check your specific vehicle’s documentation.
Beyond mileage, some vehicles use more sophisticated algorithms to determine when to trigger the “Maint Reqd” light. These algorithms may take into account factors like driving conditions, engine load, and fuel consumption to provide a more accurate indication of when maintenance is needed.
It’s important to note that sometimes the “Maint Reqd” light can illuminate prematurely due to a glitch in the car’s computer system. If you’ve recently had your oil changed and the light comes on shortly thereafter, it’s possible that the system wasn’t reset properly, or there might be a minor software issue.

Why is the “Maint Reqd” light illuminated in my car?
The “Maint Reqd” or “Maintenance Required” light is a reminder system indicating that your vehicle is due for scheduled maintenance, typically an oil change. This system uses a mileage-based or time-based trigger. The light’s primary purpose is to prompt you to bring your car in for routine servicing, ensuring that critical components are inspected and maintained, preventing potential mechanical issues and prolonging the life of your vehicle.
Ignoring the “Maint Reqd” light can lead to delayed maintenance, potentially causing increased wear and tear on engine components. While the light itself doesn’t directly indicate a serious problem, failing to address the underlying need for maintenance could eventually result in significant damage. Therefore, it’s crucial to schedule a service appointment and reset the light promptly after the maintenance has been performed.
Can I drive my car with the “Maint Reqd” light on?
Yes, you can generally drive your car with the “Maint Reqd” light illuminated. The light serves as a reminder for scheduled maintenance and does not necessarily indicate an immediate mechanical failure. Your vehicle will continue to operate, but it is important to be aware that delaying maintenance can lead to more significant problems down the line.
However, it’s essential to determine the reason for the light. If you recently had your car serviced and the light wasn’t reset properly, it’s safe to assume everything is fine and you can reset the light yourself. If you haven’t had any recent maintenance, you should schedule an appointment with a mechanic to ensure your car receives the necessary attention to avoid potential issues that could impact its reliability and safety.
What tools or equipment do I need to reset the “Maint Reqd” light?
In most cases, resetting the “Maint Reqd” light does not require any special tools or equipment. The reset procedure is typically done using the car’s instrument panel buttons or the infotainment system. The exact process can vary depending on the vehicle’s make and model, but it usually involves a specific sequence of pressing and holding buttons while the ignition is on or off.
For some older vehicles, a simple OBD II scanner might be required to reset the light, particularly if the standard reset procedures are not effective. However, this is less common. Refer to your vehicle’s owner’s manual for the specific steps outlined by the manufacturer. The manual will provide detailed instructions tailored to your car’s model and year, ensuring accurate reset of the maintenance reminder system.
How do I reset the “Maint Reqd” light if my car has a push-button start?
Resetting the “Maint Reqd” light in a car with a push-button start typically involves a similar process to those with a key-based ignition, but with slight variations. Instead of turning a key to the “on” position, you’ll usually press the start button without pressing the brake pedal. This puts the car in “accessory” or “on” mode, allowing you to access the instrument panel settings.
Once in accessory mode, navigate to the maintenance settings using the steering wheel buttons or the touchscreen display. From there, follow the specific steps outlined in your vehicle’s owner’s manual for resetting the “Maint Reqd” light. Some vehicles may require you to hold down a specific button while cycling the ignition (pressing the start button) a few times.
Will resetting the “Maint Reqd” light affect my car’s performance?
Resetting the “Maint Reqd” light itself will not directly affect your car’s performance. The light is simply a reminder system and does not control any engine functions or vehicle operations. Resetting it only clears the reminder from the instrument panel, indicating that you acknowledge the need for maintenance and have (or will) address it.
However, it’s important to remember that the underlying maintenance issues that triggered the light *can* affect your car’s performance. For example, if the light came on because your oil is old and needs changing, neglecting this maintenance will eventually lead to reduced engine efficiency and potential damage. Resetting the light without performing the necessary maintenance is only a temporary fix and can have long-term negative consequences.
What should I do if the “Maint Reqd” light comes back on shortly after resetting it?
If the “Maint Reqd” light reappears soon after being reset, it typically indicates one of two things. First, the reset procedure might not have been performed correctly. Double-check your owner’s manual and repeat the steps carefully to ensure the light was properly cleared from the system. Make sure you are following the correct sequence and timing for your specific vehicle make and model.
Secondly, and more importantly, the underlying issue that triggered the light in the first place might not have been resolved. If you reset the light without actually performing the necessary maintenance (like an oil change), the system will likely detect that the maintenance is still overdue and re-illuminate the light. Schedule a service appointment with a qualified mechanic to diagnose and address the reason for the light coming back on.
Is the “Maint Reqd” light the same as the “Check Engine” light?
No, the “Maint Reqd” (Maintenance Required) light and the “Check Engine” light are distinct indicators with different purposes. The “Maint Reqd” light is a reminder for routine scheduled maintenance, such as oil changes or tire rotations. It is triggered by a mileage or time-based interval, prompting you to bring your vehicle in for preventative care.
The “Check Engine” light, on the other hand, indicates a potential problem with the engine or emissions system. It signifies a malfunction detected by the car’s onboard diagnostics system. If the “Check Engine” light illuminates, it requires immediate attention from a qualified mechanic to diagnose the problem, which could range from a loose gas cap to a more serious engine issue. Do not ignore a “Check Engine” light.
