The dreaded maintenance light on your dashboard – it’s a signal that your 2015 Toyota Highlander is due for some attention. While it doesn’t always indicate a major problem, it’s essential to address it promptly to ensure your vehicle’s longevity and optimal performance. This comprehensive guide will walk you through the steps of clearing the maintenance light and offer insights into understanding its significance.
Understanding the Maintenance Light on Your 2015 Highlander
The maintenance light, often represented by a wrench icon, isn’t the same as the check engine light. The check engine light signals a potentially serious issue with your engine or emissions system, while the maintenance light typically indicates that scheduled maintenance is due. Think of it as a friendly reminder from your Highlander to perform routine tasks like oil changes, tire rotations, or filter replacements.
The 2015 Toyota Highlander’s maintenance schedule is designed to keep your vehicle running smoothly. Ignoring the maintenance light could lead to neglecting essential services, potentially resulting in more significant and costly repairs down the road.
Why is the Maintenance Light On?
The most common reason for the maintenance light to illuminate is that your Highlander has reached a predetermined mileage interval since the last maintenance reset. Toyota programs the system to trigger the light after a certain number of miles, typically around 5,000 miles, although this can be customized.
It’s crucial to consult your owner’s manual to understand the recommended maintenance schedule for your specific 2015 Highlander model. This will provide clarity on what services are due when the light appears.
Differentiating Between Maintenance Light and Check Engine Light
As mentioned earlier, it’s imperative to differentiate between the maintenance light and the check engine light. The check engine light often appears as an engine-shaped icon and signifies a potential problem with the engine, emissions system, or related components. If your check engine light is on, it’s recommended to have your vehicle diagnosed by a qualified mechanic as soon as possible.
Ignoring a check engine light could lead to further damage and more expensive repairs. A diagnostic scan tool can help determine the specific issue triggering the check engine light.
Step-by-Step Guide to Resetting the Maintenance Light
Fortunately, resetting the maintenance light on your 2015 Toyota Highlander is a relatively straightforward process that you can typically perform yourself. Here’s a step-by-step guide:
-
Ensure your vehicle is turned off. The engine should be completely off, but the key should be in the ignition.
-
Turn the ignition to the “ON” position without starting the engine. This means turning the key two clicks forward, so the dashboard lights illuminate.
-
Locate the “Trip” button on your instrument panel. This button is usually located near the speedometer. It’s used to cycle through the trip meters (Trip A and Trip B) and the odometer.
-
Press and hold the “Trip” button. Keep the button pressed down.
-
While still holding the “Trip” button, turn the ignition off. Keep holding the “Trip” button down.
-
Turn the ignition back to the “ON” position without starting the engine. Continue holding the “Trip” button.
-
Wait for the maintenance light to flash and then disappear. After a few seconds, you should see the maintenance light flash. Keep holding the button until the light goes out completely. This indicates that the system has been reset.
-
Release the “Trip” button. You can now release the “Trip” button.
-
Turn the ignition off and then start the engine to confirm the reset. Start the engine to verify that the maintenance light has been successfully reset. The light should no longer be illuminated on the dashboard.
Troubleshooting Resetting Issues
If the maintenance light doesn’t reset after following these steps, here are a few troubleshooting tips:
-
Ensure you’re performing the steps correctly. Double-check each step in the procedure to ensure you haven’t missed anything. The timing of holding and releasing the “Trip” button is crucial.
-
Check your owner’s manual for specific instructions. While the above procedure is generally applicable to 2015 Toyota Highlanders, your owner’s manual may contain slightly different instructions specific to your trim level or region.
-
Consider a diagnostic scan tool. In rare cases, a faulty sensor or underlying issue might be preventing the reset. A diagnostic scan tool can help identify any potential problems.
-
Seek professional assistance. If you’ve tried all the troubleshooting steps and the maintenance light still won’t reset, it’s best to consult a qualified mechanic. They can diagnose any underlying issues and ensure the light is properly reset.

Why is the maintenance light on in my 2015 Toyota Highlander?
The maintenance light illuminates in your 2015 Toyota Highlander as a reminder that it’s time for routine servicing. This is generally triggered based on mileage or a predetermined service interval. It’s important to address this light promptly as it signifies the need for an oil change, tire rotation, or other scheduled maintenance items to ensure optimal vehicle performance and longevity.
Ignoring the maintenance light can potentially lead to neglecting essential services. While the light itself doesn’t indicate a serious malfunction, delaying recommended maintenance can eventually cause more significant issues, potentially voiding warranties and incurring higher repair costs in the long run. Therefore, consult your owner’s manual and schedule the appropriate service when the maintenance light appears.
What tools do I need to reset the maintenance light on my 2015 Toyota Highlander?
Fortunately, resetting the maintenance light on your 2015 Toyota Highlander doesn’t require any special tools. The process is typically completed using the buttons and controls located on your steering wheel and the instrument panel display. No external diagnostic equipment or specialized tools are necessary.
The main items you’ll use are the trip meter reset button and the information display buttons, usually labeled “DISP” or a similar abbreviation. These are all you need to navigate the menu and reset the maintenance light indicator. It’s a simple procedure that can be performed by the owner, saving time and money.
What is the difference between the “Maintenance Required” light and the “Check Engine” light?
The “Maintenance Required” light and the “Check Engine” light serve distinctly different purposes. The “Maintenance Required” light is a reminder for routine services, such as oil changes, tire rotations, and filter replacements, based on a predetermined mileage or time interval. It’s a proactive indicator that your vehicle needs scheduled upkeep.
In contrast, the “Check Engine” light indicates a potential problem with the engine or emissions system. It often signals a more serious issue that requires immediate attention from a qualified mechanic. If the “Check Engine” light is illuminated, it’s crucial to have your vehicle diagnosed to prevent further damage and ensure it is operating efficiently and safely.
How do I reset the maintenance light if I have the multi-information display in my 2015 Toyota Highlander?
If your 2015 Toyota Highlander has the multi-information display, start by turning the ignition on (but don’t start the engine). Use the trip meter reset button to cycle through the display options until you see “Trip A”. Turn the ignition off. Now, press and hold the trip meter reset button while turning the ignition back on (without starting the engine).
Continue holding the reset button until you see the maintenance data reset option on the display. It might show a countdown or flashing zeros. Release the button once the reset is complete. This process recalibrates the system, turning off the maintenance light and setting the reminder for the next scheduled service interval.
What if the maintenance light comes back on shortly after I reset it?
If the maintenance light reappears shortly after you’ve reset it, it could indicate a couple of possibilities. First, ensure you followed the reset procedure correctly. A slight variation in the steps can sometimes prevent a successful reset. Repeat the process carefully, paying close attention to each step.
Alternatively, the light might be genuinely indicating an underlying issue. Even after resetting the light, the system might detect that necessary maintenance wasn’t actually performed or that a different problem has arisen. In this case, it is advisable to consult a qualified mechanic to diagnose and address any potential issues before they escalate into more significant problems.
Can resetting the maintenance light damage my 2015 Toyota Highlander?
Resetting the maintenance light itself will not damage your 2015 Toyota Highlander as long as the procedure is followed correctly. The reset is a standard function designed to be performed by vehicle owners or technicians after routine maintenance. The vehicle’s computer system is programmed to handle this action without any adverse effects.
However, remember that resetting the light doesn’t replace the actual maintenance required. Neglecting necessary services, even after resetting the light, can lead to potential mechanical problems and increased repair costs down the road. Always prioritize regular maintenance according to your owner’s manual to keep your Highlander running smoothly.
Is there a way to prevent the maintenance light from coming on in the first place?
The maintenance light is designed to come on as a reminder for scheduled service intervals, and it can’t be permanently prevented from appearing. However, proactively adhering to your vehicle’s maintenance schedule outlined in the owner’s manual is the best way to manage its appearance. Following this schedule ensures timely oil changes, tire rotations, and other necessary services.
By staying on top of your Highlander’s maintenance needs, you not only keep the maintenance light predictable but also help extend the lifespan of your vehicle and maintain its optimal performance. Regular servicing catches potential issues early, preventing them from becoming more significant and costly repairs.
