2020 Toyota 4Runner Oil Light Reset: Maintenance Tips

How to Reset Your 2020 Toyota 4Runner Maintenance Light Like a Pro: A Practical Walkthrough

The “Maintenance Required” light on your 2020 Toyota 4Runner is a persistent reminder that your vehicle is due for its periodic check-up, primarily an oil change and tire rotation. While this light is essential for vehicle longevity, it does not reset itself automatically just because you changed the oil. Learning how to manually reset this system is a vital skill for any DIY enthusiast or 4Runner owner who prefers to handle their own basic maintenance. This guide covers the digital reset process specifically for the 2020 model year, which utilizes the steering wheel controls and the Multi-Information Display (MID) rather than the older odometer button method found in previous generations. Following these steps ensures your vehicle’s computer is accurately tracking your next 5,000-mile interval.

Step 1: Preparing the Vehicle Electronics

What you need: Your 2020 Toyota 4Runner key fob and a clear view of the instrument cluster.

Instructions: Before you can access the deep settings of the 4Runner’s computer, you need to power the vehicle’s electronics without actually cranking the engine. If your 4Runner has a traditional key, insert it and turn it to the “On” position (position II). If you have a Push-Button Start model, which is common in the 2020 TRD and Limited trims, press the “Start” button twice without pressing your foot on the brake pedal. You will see the dashboard light up like a Christmas tree, and the Multi-Information Display (the digital screen in the center of your gauges) will go through its startup animation. It is crucial that the engine remains off during this process, as many of the deeper customization and reset menus are locked while the engine is running for safety reasons.

Pro Tip: If the engine accidentally starts, the reset menu might be greyed out or inaccessible. Simply turn the vehicle completely off, wait five seconds for the modules to power down, and try the double-press method again without touching the brake.

Step 2: Navigating to the Settings Menu

What you need: Use the directional keypad located on the right-hand side of your steering wheel.

Instructions: Once the instrument cluster is fully powered, look at the digital screen between the tachometer and the speedometer. You will likely see your current fuel economy or digital speedometer. Using the left or right arrows on your steering wheel’s directional pad, toggle through the top-level menu icons. These icons represent different categories like “Drive Information,” “Navigation,” and “Audio.” You are looking for the icon that resembles a small gear or sprocket, which represents the “Settings” menu. This icon is typically located at the far right of the menu ribbon. As you scroll, the screen will highlight each category; stop once the gear icon is highlighted in the center of the display.

Pro Tip: If you see a warning message (like “Low Fuel” or “Door Ajar”), you must first clear it by pressing the “Back” button or “OK” button on the steering wheel before you can navigate the menus.

Step 3: Accessing the Vehicle Settings Sub-Menu

What you need: The “OK” button and the vertical (up/down) arrows on the steering wheel keypad.

Instructions: Now that you are in the Settings (gear icon) menu, you will see a list of various sub-menus such as “LTA” (Lane Tracing Assist), “PCS” (Pre-Collision System), and “Display Settings.” You need to scroll down using the down arrow on your steering wheel until you find the option labeled “Vehicle Settings.” Note that on the 2020 model, this is often represented by a small icon of a car with a gear inside it. Once “Vehicle Settings” is highlighted, press and hold the “OK” button in the center of your directional pad for about two seconds. Simply tapping it might not work; a firm hold is often required to enter this specific administrative menu where maintenance data is stored.

Pro Tip: If you accidentally enter the “Meter Settings” instead, just hit the “Back” button (the curved arrow) to return to the main list and try selecting “Vehicle Settings” again.

Step 4: Locating the Scheduled Maintenance Option

What you need: Continued use of the vertical directional arrows on the steering wheel.

Instructions: Inside the “Vehicle Settings” menu, you will be presented with a few options, typically including “TPMS” (Tire Pressure Monitoring System) and “Scheduled Maintenance.” Depending on your specific software version, you might also see “Oil Maintenance.” For a full reset of the service light, you want to highlight “Scheduled Maintenance.” This is the primary timer that triggers the “Maintenance Required” message every 5,000 miles. Use the down arrow to navigate to this line item. Ensure it is fully highlighted before proceeding, as selecting the wrong option could inadvertently reset your tire pressure sensors instead of your oil life timer, leading to a confusing warning light later down the road.

Pro Tip: On some 2020 4Runner trims, resetting “Scheduled Maintenance” resets the overall light, while “Oil Maintenance” specifically resets the oil life monitor. For best results after a full service, it is recommended to reset both if they appear as separate options.

Step 5: Confirming the Maintenance Reset

What you need: The “OK” button and the directional pad.

Instructions: After selecting “Scheduled Maintenance,” the screen will change to a confirmation prompt asking, “Reset Data?” Below this question, you will see two options: “Yes” and “No.” By default, “No” is usually highlighted to prevent accidental resets. Press the up arrow to highlight the “Yes” option. Once “Yes” is selected, press the “OK” button one last time. The screen will briefly display a message that says “Resetting Maintenance Data” or “Reset Complete,” accompanied by a small progress bar. Once the bar fills and the message disappears, the vehicle has officially logged that the maintenance has been performed and has restarted the 5,000-mile countdown. You have now successfully cleared the internal timer that triggers the dashboard warning.

Pro Tip: Do not turn the vehicle off while the “Resetting…” progress bar is on the screen. Interrupting the power during this data-write process can occasionally cause the reset to fail, requiring you to start the process over from Step 1.

Step 6: Final Verification and Power Down

What you need: Brake pedal and the Start/Stop button (or key).

Instructions: To ensure the reset “stuck,” you should perform a power cycle. Press the “Back” button on your steering wheel several times to return to your preferred home screen (like the digital speedometer). Now, turn the vehicle completely off. To verify, start the engine normally by pressing the brake pedal and pushing the Start/Stop button (or turning the key to the Start position). Observe the instrument cluster as the vehicle starts. The “Maintenance Required” message that previously appeared during the startup sequence should now be gone. If the screen remains clear of maintenance warnings, your 2020 4Runner is ready for the next 5,000 miles of adventure. If the light persists, it usually means the “Yes” confirmation in Step 5 wasn’t fully registered, and you should repeat the steps.

Pro Tip: Use this moment to also check your oil dipstick one last time if you just performed the oil change. It is best practice to verify the mechanical work and the electronic reset at the same time for total peace of mind.

✅ Final Checklist

• Confirm the “Maintenance Required” text no longer appears upon engine startup.
• Verify that the “Scheduled Maintenance” reset was confirmed with the “Reset Complete” message.
• Ensure the Multi-Information Display (MID) has been returned to your preferred viewing screen (e.g., Speedometer or Fuel Range).
• Double-check that you did not accidentally reset the TPMS (Tire Pressure) system instead of the maintenance system.
• Record the current mileage and date in your physical maintenance logbook or the Toyota app for warranty backup.

Important Notes:

• Safety First: Always perform this reset while the vehicle is in “Park” and the emergency brake is engaged. Never attempt to navigate these menus while the vehicle is in motion.
• Professional Help: If the “Maintenance Required” light is accompanied by a “Check Engine” light (an amber engine-shaped icon), a simple reset will not solve the problem. You should visit a technician to have the OBD-II codes scanned.
• Estimated Time and Cost: This process takes approximately 2-4 minutes and costs $0. Performing this yourself saves the $20-$40 “diagnostic” or “reset fee” some quick-lube shops might charge if they forget to do it during your oil change.
