The dreaded “Maintenance Required” light. It’s a sight familiar to many drivers, and it can spark a moment of mild panic, especially when it illuminates on the dashboard of your reliable 2015 Toyota Highlander. But what does it really mean? Is your car about to break down? Do you need to pull over immediately? The answer, thankfully, is usually no.
This article will delve deep into the meaning behind the “Maintenance Required” light on your 2015 Toyota Highlander, explaining what triggers it, what it likely indicates, and, most importantly, what steps you should take to address it. We’ll cover everything from the simple fixes to the more complex scenarios, empowering you with the knowledge to keep your Highlander running smoothly for years to come.
Understanding the “Maintenance Required” Light
The “Maintenance Required” light isn’t a warning about a catastrophic engine failure or a critical system malfunction, at least not directly. Instead, it’s a preemptive reminder that your vehicle is due for routine maintenance, primarily an oil change. Think of it as a friendly nudge from your Highlander’s computer, reminding you to keep up with its scheduled service intervals.
This system is programmed by Toyota based on mileage. The light is designed to illuminate a certain number of miles before the recommended oil change interval. This gives you ample time to schedule a service appointment with your preferred mechanic or Toyota dealership.
It’s important to distinguish this from the “Check Engine” light. The “Check Engine” light (sometimes referred to as the MIL or Malfunction Indicator Lamp) indicates a problem with your engine, emissions system, or other critical components. It requires immediate attention and diagnostic testing to pinpoint the underlying issue. The “Maintenance Required” light is far less urgent.
Common Triggers for the Light on a 2015 Highlander
As mentioned earlier, the most common reason for the “Maintenance Required” light to appear on your 2015 Toyota Highlander is an impending oil change. Toyota generally recommends oil changes every 5,000 to 10,000 miles, depending on the type of oil used (conventional vs. synthetic) and your driving conditions.
However, the light might also be triggered if a previous maintenance interval was not properly reset. Even if you’ve recently had your oil changed, if the service technician didn’t reset the system, the light will still illuminate according to the pre-programmed schedule. This is a very common occurrence and easily rectified.
Beyond oil changes, the light could theoretically be linked to other maintenance items, although less directly. For instance, if you’re consistently neglecting other scheduled services, the computer might use the oil change interval as a general reminder that your vehicle is overdue for multiple checks.
What to Do When the Light Comes On
The first step is to remain calm. As we’ve established, the “Maintenance Required” light isn’t an emergency signal. Take a moment to assess the situation and determine when your last oil change was.
Check your service records. Your Highlander’s maintenance schedule is outlined in your owner’s manual. Refer to this to see what services are recommended at your current mileage. This will help you determine if the light is related to an oil change or another scheduled maintenance item.
If your oil change is due, schedule an appointment with your trusted mechanic or Toyota dealership. In the meantime, you can continue driving your Highlander without immediate concern. However, delaying maintenance indefinitely is never a good idea.
If you recently had your oil changed, the light was likely not reset properly. In this case, you can try resetting it yourself following the instructions outlined in the next section. If you’re uncomfortable doing this, you can always take it back to the service center that performed the oil change and ask them to reset the system.
Resetting the “Maintenance Required” Light on a 2015 Toyota Highlander
Resetting the “Maintenance Required” light on a 2015 Toyota Highlander is a relatively simple procedure that most owners can perform themselves. Here’s a step-by-step guide:
-
Ensure the vehicle is completely off. The ignition should be in the “off” position, and all accessories should be turned off.
-
Press and hold the trip meter reset button. This is the button on the instrument panel used to reset your trip odometer. Locate it and press and hold it down.
-
Turn the ignition to the “on” position (without starting the engine). Keep holding down the trip meter reset button. The instrument panel lights will illuminate.
-
Continue holding the trip meter reset button until the “Maintenance Required” light flashes and then turns off. This usually takes about 5-10 seconds. You might see a series of dashes appear on the odometer display before the light resets.
-
Release the trip meter reset button.
-
Turn the ignition off and then back on to confirm the light has been reset. The “Maintenance Required” light should no longer be illuminated.
If the light doesn’t reset after following these steps, repeat the process carefully. Ensure you are holding the trip meter reset button down firmly throughout the procedure. If you still can’t reset the light, it’s possible there’s another underlying issue that needs to be addressed by a professional.
The Importance of Regular Maintenance
While the “Maintenance Required” light specifically focuses on oil changes, it serves as a broader reminder of the importance of adhering to your 2015 Toyota Highlander’s recommended maintenance schedule. Neglecting regular maintenance can lead to a host of problems, including:
- Reduced fuel efficiency.
- Decreased performance.
- Increased wear and tear on engine components.
- Potential for costly repairs down the road.
- Reduced vehicle lifespan.
Toyota provides a detailed maintenance schedule in your owner’s manual, outlining the recommended service intervals for various components and systems. This schedule typically includes oil changes, filter replacements (air filter, cabin air filter), fluid checks (coolant, brake fluid, power steering fluid), tire rotations, brake inspections, and more.
Sticking to this schedule will help ensure your Highlander runs reliably and efficiently for many years to come. It will also help maintain its resale value.
Beyond Oil Changes: Other Maintenance Items
While the “Maintenance Required” light is most often linked to oil changes, it’s a good opportunity to consider other important maintenance tasks. Here are a few key items to keep in mind for your 2015 Toyota Highlander:
-
Tire rotations: Rotating your tires regularly helps ensure even wear and extends their lifespan. Toyota typically recommends tire rotations every 5,000 to 7,500 miles.
-
Brake inspections: Your brakes are crucial for safety. Have them inspected regularly to ensure they are functioning properly. This includes checking the brake pads, rotors, and brake fluid levels.
-
Fluid checks: Regularly check and top off your vehicle’s fluids, including coolant, brake fluid, power steering fluid, and windshield washer fluid.
-
Air filter replacement: A clean air filter helps ensure optimal engine performance and fuel efficiency. Replace your air filter as recommended in your owner’s manual.
-
Cabin air filter replacement: The cabin air filter cleans the air that enters the passenger compartment. Replacing it regularly helps improve air quality and reduce allergens.
When to Seek Professional Help
While you can handle many basic maintenance tasks yourself, there are times when it’s best to seek professional help from a qualified mechanic. Consider taking your 2015 Toyota Highlander to a professional if:
- You’re uncomfortable performing maintenance tasks yourself.
- You suspect a more serious problem with your vehicle.
- The “Check Engine” light is illuminated in addition to the “Maintenance Required” light.
- You’re experiencing unusual symptoms, such as strange noises, vibrations, or a decrease in performance.
- You’ve tried resetting the “Maintenance Required” light, but it keeps coming back on.
A qualified mechanic can diagnose and repair any underlying issues, ensuring your Highlander is running safely and efficiently.
Preventative Maintenance: A Long-Term Investment
Think of preventative maintenance as an investment in the long-term health and reliability of your 2015 Toyota Highlander. By proactively addressing maintenance needs, you can avoid costly repairs down the road and extend the life of your vehicle.
Regular oil changes, tire rotations, brake inspections, and fluid checks are all essential components of a comprehensive preventative maintenance program. Following your vehicle’s recommended maintenance schedule and addressing any issues promptly will help ensure your Highlander remains a dependable and enjoyable vehicle for many years to come.
Furthermore, keeping detailed records of all maintenance performed can be invaluable when it comes time to sell or trade in your Highlander. A well-maintained vehicle is always more desirable and commands a higher resale value.
Ultimately, understanding the meaning behind the “Maintenance Required” light on your 2015 Toyota Highlander and taking appropriate action is crucial for maintaining its performance, reliability, and longevity.

This interval aligns with the common recommendation for oil changes and tire rotations under normal driving conditions. However, the frequency may vary depending on your driving habits and the type of oil you use. For instance, if you frequently engage in severe driving conditions, such as towing or stop-and-go traffic, you might consider more frequent maintenance.
It’s crucial to consult your owner’s manual for the specific maintenance schedule recommended for your 2015 Toyota Highlander. This document outlines the various maintenance tasks required at different mileage intervals. Remember, the 5,000-mile interval is just a general guideline, and your vehicle may require more frequent or less frequent maintenance based on your individual circumstances and the recommendations in your owner’s manual.
What specific maintenance tasks are usually due when the “Maintenance Required” light comes on?
When the “Maintenance Required” light illuminates on your 2015 Toyota Highlander, the most common maintenance task due is an oil change. This includes replacing the engine oil and oil filter. Regular oil changes are essential for maintaining engine lubrication and preventing wear and tear. Alongside the oil change, a tire rotation is also typically recommended at this interval.
Beyond the oil change and tire rotation, it’s a good practice to perform a general inspection of your vehicle. This includes checking fluid levels (brake fluid, power steering fluid, coolant, windshield washer fluid), inspecting belts and hoses for wear, and examining the condition of your brakes. These checks can help identify potential problems early on and prevent costly repairs in the future. Consult your owner’s manual for a comprehensive list of recommended maintenance tasks at this mileage interval.
Can I reset the “Maintenance Required” light myself on my 2015 Toyota Highlander?
Yes, you can typically reset the “Maintenance Required” light on your 2015 Toyota Highlander yourself. The procedure usually involves using the trip meter reset button and turning the ignition key to specific positions. The exact steps may vary slightly depending on the specific model year and trim, but the general principle remains the same.
Refer to your owner’s manual for detailed instructions on how to reset the light. Following the steps carefully will ensure that the light is properly reset and doesn’t continue to illuminate unnecessarily. If you are uncomfortable performing the reset yourself, you can always have a mechanic or service technician reset the light for you after completing the necessary maintenance.
What happens if I ignore the “Maintenance Required” light on my 2015 Toyota Highlander?

Regular maintenance helps ensure the longevity and reliability of your Highlander. Addressing the issues prompted by the “Maintenance Required” light in a timely manner is crucial for preserving your vehicle’s value and performance.
Is the “Maintenance Required” light the same as the “Check Engine” light on my 2015 Toyota Highlander?
