Resetting the engine maintenance light on your 2020 Toyota Corolla is quick and simple—no mechanic needed. This guide walks you through the exact steps using the dashboard controls, so you can clear the reminder after an oil change or service and keep your car running smoothly.
Key Takeaways
- Know when to reset: Only reset the maintenance light after completing the required service, such as an oil change or tire rotation.
- Use the trip meter button: The reset process relies on the trip meter button and the odometer display—no special tools or scanners are needed.
- Turn the ignition on (but don’t start the engine): This puts the car in accessory mode, allowing access to the maintenance menu.
- Follow the sequence carefully: Pressing buttons in the wrong order can prevent the reset from working—patience is key.
- Confirm the reset: The maintenance light should disappear from the dashboard once the process is complete.
- Don’t ignore regular maintenance: Resetting the light doesn’t replace actual service—stay on top of your Corolla’s maintenance schedule.
- Consult your owner’s manual: If you’re unsure, the official Toyota manual provides model-specific guidance.

Understanding the Maintenance Light

Before diving into the reset process, it’s important to understand what the engine maintenance light actually means. On the 2020 Toyota Corolla, this light—often labeled “Maintenance Required” or displayed as a wrench icon—is part of Toyota’s Maintenance Reminder System (MRS).
This system tracks your driving habits and mileage to estimate when routine service is due. It typically triggers after approximately 5,000 to 10,000 miles, depending on your driving conditions. The light doesn’t indicate a problem with your engine—it’s simply a reminder that it’s time for scheduled maintenance like an oil change, tire rotation, or filter replacement.
It’s crucial to note that the maintenance light is different from the “Check Engine” light. The Check Engine light signals a potential mechanical or emissions issue and should be addressed immediately. The maintenance light, on the other hand, is preventive and routine.
Once you’ve completed the recommended service, the light will remain on until you manually reset it. That’s why knowing how to reset the engine maintenance light on your 2020 Corolla is such a valuable skill. It helps you stay organized and ensures you don’t miss future service intervals.
Tools and Preparation
The great news? You don’t need any special tools to reset the maintenance light on your 2020 Corolla. Everything you need is already built into your vehicle’s dashboard and controls. Here’s what you’ll need:
– Your 2020 Toyota Corolla (obviously!)
– The ignition key or key fob (if your model has push-button start)
– A few minutes of your time
Before starting, make sure your car is parked on a flat surface with the engine off. If you’ve just driven the car, allow the engine to cool for a few minutes. This isn’t strictly necessary for the reset process, but it’s a good safety practice.
Also, double-check that the required maintenance has actually been completed. Resetting the light without performing the service defeats the purpose of the reminder system and could lead to missed maintenance down the road.
Step-by-Step Reset Instructions
Now that you’re prepared, let’s walk through the exact steps to reset the engine maintenance light on your 2020 Corolla. Follow these instructions carefully to ensure success.
Step 1: Turn the Ignition to “On” (Do Not Start the Engine)
Insert your key into the ignition and turn it to the “ON” position. If your Corolla has a push-button start, press the “Start” button once without pressing the brake pedal. This will power up the dashboard and electronics but won’t crank the engine.
You’ll know you’re in the right mode when all the dashboard lights illuminate, including the maintenance light. The engine should remain off—you’ll hear no cranking or startup sounds.
This step is critical because the reset process requires the car’s computer system to be active, but the engine doesn’t need to be running.
Step 2: Locate the Trip Meter Button
Next, find the trip meter button on your dashboard. On the 2020 Corolla, this button is typically located on the instrument cluster, near the speedometer. It’s a small, round button labeled “TRIP” or sometimes just marked with a “T.”
This button allows you to switch between different trip odometer readings (Trip A and Trip B) and access the maintenance menu. You’ll be using it repeatedly during the reset process, so make sure you can easily reach it.
If you’re having trouble finding it, look just below or to the side of the speedometer display. On some models, it may be integrated into the steering column stalk, but on most 2020 Corollas, it’s a standalone button on the dashboard.
Step 3: Navigate to the Maintenance Menu
With the ignition on and the engine off, press and hold the trip meter button. While holding it down, watch the odometer or trip display on your dashboard.
After a few seconds, the display should change from showing mileage to displaying a menu option. You’re looking for something like “Maintenance Reset” or “Oil Reset.” On some models, it may simply show “—” or a blank line with a blinking cursor.
If you don’t see this option right away, continue holding the button. The system cycles through different menu items, so it may take a few seconds to appear.
Once you see the maintenance reset option, release the button. You’ve now entered the reset menu.
Step 4: Confirm the Reset
Now that you’re in the maintenance reset menu, you’ll need to confirm that you want to reset the light. To do this, press and hold the trip meter button again.
Hold it down for about 5 to 10 seconds. During this time, you should see the display change or hear a beep (on some models). The maintenance light on your dashboard should begin to flash or turn off completely.
After holding the button, release it. The system should now reset the maintenance reminder, and the light should disappear from the dashboard.
If the light is still on, don’t panic—try the process again. Sometimes it takes a second attempt, especially if the button wasn’t held long enough.
Step 5: Turn Off the Ignition
Once the maintenance light is off, turn the ignition back to the “OFF” position. If you have a push-button start, press the “Start” button again to shut everything down.
Wait a few seconds, then restart the car normally. When you turn the ignition back on, check the dashboard. The maintenance light should no longer be illuminated.
If it’s still there, repeat the steps above. Make sure you’re holding the trip button long enough and that the ignition is in the correct position.
Tips for Success
Resetting the maintenance light is usually straightforward, but a few tips can help ensure a smooth process:
– Be patient: The system may take a few seconds to respond. Don’t rush the button presses.
– Use a steady hand: Press the trip button firmly and hold it without tapping or releasing too early.
– Check your owner’s manual: If the steps don’t work, your specific trim or model may have slight variations. The manual is your best resource.
– Reset after every service: Make it a habit to reset the light each time you complete maintenance. This keeps your records accurate.
– Keep a maintenance log: Note the date, mileage, and type of service performed. This helps you stay on schedule and can increase your car’s resale value.
Troubleshooting Common Issues
Even with clear instructions, you might run into a few hiccups. Here are some common problems and how to fix them:
The Light Won’t Turn Off
If the maintenance light remains on after following the steps, try repeating the process. Sometimes the system doesn’t register the reset on the first try. Make sure you’re holding the trip button long enough—aim for at least 10 seconds.
Also, double-check that the ignition is in the “ON” position and not accidentally started. The engine must be off during the reset.
The Menu Doesn’t Appear
If pressing the trip button doesn’t bring up the maintenance menu, your Corolla may have a different interface. Some models require you to cycle through trip modes first. Try pressing the trip button repeatedly to switch between Trip A and Trip B, then hold it down to access the menu.
Alternatively, your vehicle may require a different method. Consult your owner’s manual or visit a Toyota service center for assistance.
The Button Feels Stiff or Unresponsive
Over time, dashboard buttons can become less responsive due to dust or wear. Try cleaning around the trip button with a soft, dry cloth. Avoid using liquids, as they can damage the electronics.
If the button is physically damaged, you may need to have it repaired. In the meantime, you can still reset the light using a professional scan tool at a dealership or auto shop.
The Light Comes Back On Quickly
If the maintenance light reappears shortly after resetting, it could mean one of two things:
1. The system detected that the service interval has already been reached again (unlikely unless you’ve driven thousands of miles).
2. The reset didn’t fully complete, and the system is still tracking the previous interval.
In most cases, repeating the reset process will resolve the issue. If the light continues to return, have your vehicle inspected to ensure there are no underlying problems.
Why Regular Maintenance Matters
While resetting the maintenance light is a simple task, it’s important to remember why the reminder exists in the first place. Regular maintenance is essential for keeping your 2020 Corolla running efficiently, safely, and reliably.
Routine services like oil changes, tire rotations, brake inspections, and fluid top-offs help prevent wear and tear, improve fuel economy, and extend the life of your vehicle. Skipping maintenance can lead to costly repairs down the road—far more expensive than the cost of regular service.
By resetting the light after each service, you’re not just clearing a dashboard warning—you’re staying on top of your car’s health. Think of it as a digital checklist that helps you stay organized and proactive.
Toyota recommends following the maintenance schedule outlined in your owner’s manual. This typically includes:
– Oil and filter change every 5,000 to 10,000 miles
– Tire rotation every 5,000 to 7,500 miles
– Brake inspection every 15,000 miles
– Air filter replacement every 15,000 to 30,000 miles
– Coolant and brake fluid checks every 30,000 miles
Sticking to this schedule—and resetting the light each time—ensures your Corolla stays in peak condition for years to come.
Alternative Methods (If the Standard Reset Fails)
In rare cases, the standard reset method may not work. This can happen due to software glitches, battery issues, or model-specific variations. If you’ve tried the steps multiple times without success, here are a few alternatives:
Use a Professional Scan Tool
Auto parts stores and dealerships have diagnostic tools that can reset the maintenance light electronically. This is a reliable option if the manual method fails. Many stores offer this service for free or a small fee.
Disconnect the Battery
As a last resort, you can try disconnecting the car’s battery for about 10 to 15 minutes. This resets the vehicle’s computer system and may clear the maintenance light. However, this method can also reset other settings like radio presets and clock time, so use it cautiously.
To disconnect the battery:
1. Turn off the ignition and remove the key.
2. Locate the negative terminal (marked with a “-”) on the battery.
3. Use a wrench to loosen the clamp and remove the cable.
4. Wait 10–15 minutes, then reconnect the cable.
5. Start the car and check if the light is off.
Note: This method doesn’t always work for maintenance lights and may trigger other warning lights temporarily.
Visit a Toyota Service Center
If all else fails, schedule an appointment with a Toyota dealership. Their technicians can reset the light using factory tools and ensure your vehicle’s systems are functioning correctly.
Conclusion
Resetting the engine maintenance light on your 2020 Toyota Corolla is a quick and easy process that every owner should know. With just the trip meter button and a few simple steps, you can clear the reminder after an oil change or service—no tools or expertise required.
By following this guide, you’ll save time and money by avoiding unnecessary trips to the mechanic. More importantly, you’ll stay on top of your car’s maintenance schedule, ensuring your Corolla runs smoothly and efficiently for years to come.
Remember: the maintenance light is there to help you, not hassle you. Reset it promptly after each service, keep a record of your maintenance history, and enjoy the reliability that comes with proper care.
