The dreaded “Maintenance Required” light. It’s a familiar sight for many Toyota Highlander owners, often appearing when you’re least expecting it. While it can cause a moment of panic, understanding its purpose and knowing how to reset it can save you time and unnecessary trips to the mechanic. This message isn’t always indicative of a major problem; often, it’s simply a reminder that your Highlander is due for routine maintenance, such as an oil change. This comprehensive guide will walk you through everything you need to know about the “Maintenance Required” message on your Toyota Highlander, from understanding its meaning to various methods of resetting it.
Understanding the “Maintenance Required” Message
The “Maintenance Required” message is a proactive feature integrated into your Toyota Highlander’s onboard computer system. It’s designed to serve as a timely reminder for scheduled maintenance, primarily oil changes, but it can also be linked to other routine services depending on your Highlander’s model year and configuration. This system works by tracking the mileage accumulated since the last reset, typically coinciding with your last oil change.
The message isn’t always a sign of a serious mechanical issue. It’s a pre-programmed prompt to ensure your Highlander receives the necessary attention to keep it running smoothly and efficiently. Ignoring this message for extended periods, however, can lead to neglecting essential maintenance, which could potentially result in more significant and costly repairs down the line. It’s crucial to distinguish between the “Maintenance Required” message and other warning lights, such as the check engine light, which indicates a more pressing problem.
Interpreting the Message
The “Maintenance Required” message doesn’t specify the exact type of maintenance needed. Instead, it’s a general reminder that your vehicle is due for servicing. Consulting your Highlander’s owner’s manual is the best way to determine the specific maintenance tasks that are recommended at the mileage interval indicated by the message. Common services include oil changes, filter replacements (air, cabin air, fuel), tire rotations, and fluid checks (coolant, brake fluid, power steering fluid).
Pay close attention to any other warning lights that may accompany the “Maintenance Required” message. If the check engine light, brake warning light, or any other indicator is illuminated, it’s essential to address those issues promptly, as they could signal a more serious problem that requires immediate attention.
Why It’s Important to Address the Message
While the “Maintenance Required” message might seem like a minor annoyance, ignoring it can have several negative consequences. Firstly, neglecting routine maintenance can lead to decreased fuel efficiency. Dirty oil and clogged filters can hinder engine performance, forcing it to work harder and consume more fuel. Secondly, it can shorten the lifespan of your Highlander. Regular maintenance helps prevent premature wear and tear on critical components, extending the overall life of your vehicle. Finally, ignoring the message can void your warranty. Most manufacturer warranties require adherence to the recommended maintenance schedule, and failing to do so can invalidate your coverage.
Methods for Resetting the “Maintenance Required” Message
Once you’ve performed the necessary maintenance, such as an oil change, you’ll need to reset the “Maintenance Required” message. Fortunately, Toyota Highlanders offer a straightforward process for resetting the system. The exact steps may vary slightly depending on the year and model of your Highlander, but the general principle remains the same. Here are several methods you can use.

Dealing with Persistent Messages
In some cases, the “Maintenance Required” message may persist even after attempting the reset procedures. This could be due to a few reasons:
- Incorrect Reset Procedure: Double-check that you are following the correct reset procedure for your specific Highlander model year. Consult your owner’s manual for detailed instructions.

Staying Ahead of Maintenance
Proactive maintenance is the best way to prevent problems and extend the life of your Toyota Highlander. Regularly inspecting your vehicle and addressing minor issues before they become major problems can save you time, money, and headaches in the long run.
- Regular Inspections: Take some time each month to inspect your Highlander for any signs of wear and tear, leaks, or damage. Check the tires for proper inflation and tread depth, inspect the brakes for wear, and listen for any unusual noises.
- Follow the Maintenance Schedule: Adhere to the recommended maintenance schedule outlined in your owner’s manual. This will ensure that your Highlander receives the necessary services at the appropriate intervals.
- Address Problems Promptly: Don’t ignore warning lights or unusual symptoms. Addressing problems promptly can prevent them from escalating into more serious and costly repairs.
By being proactive and staying on top of maintenance, you can keep your Toyota Highlander running smoothly and reliably for years to come. A well-maintained Highlander is a safe and dependable Highlander.
What does the “Maintenance Required” light on my Toyota Highlander mean?
The “Maintenance Required” light is a reminder that your Toyota Highlander is due for scheduled maintenance, such as an oil change. It’s a pre-programmed notification based on mileage or time intervals set by Toyota, and it’s designed to help you keep your vehicle running smoothly by adhering to the recommended service schedule. While it doesn’t necessarily indicate a serious mechanical problem, ignoring it can lead to neglecting essential maintenance tasks, which could eventually result in more costly repairs down the line.
Think of it as a friendly nudge from your Highlander to ensure you’re keeping up with its needs. The specific maintenance items required will vary depending on your Highlander’s year, mileage, and driving conditions. Refer to your owner’s manual or consult with a trusted mechanic to determine exactly what services are needed when the light illuminates.
Can I still drive my Toyota Highlander if the “Maintenance Required” light is on?
Yes, you can generally still drive your Toyota Highlander with the “Maintenance Required” light illuminated. It is a reminder for routine service and doesn’t usually indicate an immediate, critical issue. However, it’s crucial to understand that the light is a prompt to address necessary maintenance soon, rather than a permission slip to delay indefinitely.
Driving for extended periods with the light on, especially without checking the vehicle’s condition and service needs, could potentially lead to problems down the road. Ignoring scheduled maintenance can cause decreased fuel efficiency, accelerated wear and tear on vehicle components, and potentially more serious mechanical issues that could have been prevented. Prioritize addressing the maintenance requirements promptly to maintain your Highlander’s reliability and performance.
How do I reset the “Maintenance Required” light on my Toyota Highlander after an oil change?
Resetting the “Maintenance Required” light typically involves a simple sequence using the trip meter reset button on your dashboard. First, turn the ignition on, but do not start the engine. Then, press and hold the trip meter reset button until the odometer displays “Trip A.” Next, turn the ignition off.
While holding the trip meter reset button, turn the ignition back on (without starting the engine). Continue holding the button until the odometer displays a series of dashes and then resets to zero. This process will reset the maintenance reminder system, turning off the light. If this method doesn’t work, consult your owner’s manual for specific instructions related to your Highlander’s model year.
What happens if I don’t reset the “Maintenance Required” light after performing maintenance?
If you don’t reset the “Maintenance Required” light after performing the necessary maintenance, the light will remain illuminated. This means you’ll continue to receive the reminder even though the service has been completed, which can be distracting and might lead you to believe there’s still an outstanding maintenance need.
The persistent light defeats the purpose of the reminder system. It could lead you to overlook future genuine maintenance needs, as you might become accustomed to seeing the light and dismiss it. Resetting the light is a crucial step in ensuring the system accurately reflects your Highlander’s maintenance schedule.
Is the “Maintenance Required” light the same as the “Check Engine” light?
No, the “Maintenance Required” light and the “Check Engine” light are not the same, and they indicate different issues. The “Maintenance Required” light is a simple reminder for routine scheduled maintenance, such as an oil change or tire rotation, based on time or mileage intervals. It’s a preventative measure to help you keep up with your vehicle’s needs.
The “Check Engine” light, on the other hand, indicates a potential problem with the engine or emissions system. It often signals a malfunction that requires immediate attention, as it could be related to a more serious issue that affects your Highlander’s performance, fuel efficiency, or emissions control. If the “Check Engine” light comes on, it’s best to have your vehicle diagnosed by a qualified mechanic as soon as possible.
Can I reset the “Maintenance Required” light without performing any maintenance?
While it is possible to reset the “Maintenance Required” light without actually performing any maintenance, doing so is strongly discouraged. The light serves as a reminder for crucial services, and disabling it without addressing the underlying needs can lead to neglecting essential maintenance tasks. This can ultimately result in more significant and costly repairs in the long run.
Resetting the light without performing maintenance is akin to ignoring a symptom without addressing the underlying cause. While the symptom (the light) disappears, the problem remains. This can lead to accelerated wear and tear on your vehicle’s components, decreased fuel efficiency, and potentially more severe mechanical issues down the line. Always prioritize performing the necessary maintenance when the light illuminates to maintain your Highlander’s reliability and performance.
What tools or equipment do I need to reset the “Maintenance Required” light on my Toyota Highlander?
Typically, no special tools or equipment are required to reset the “Maintenance Required” light on a Toyota Highlander. The reset procedure usually involves using the trip meter reset button located on the instrument panel. This button is generally accessible and easy to use without needing any external devices.
However, it’s always a good idea to consult your Highlander’s owner’s manual for the specific reset procedure for your model year. In some cases, specific models or trim levels might have slight variations in the reset process. But in the vast majority of cases, the trip meter reset button is the only “tool” you’ll need.
