2021 Toyota 4Runner Oil Light Reset: Expert Maintenance Tips

Master the 2021 Toyota 4Runner Maintenance Reset in 7 Simple Steps

The “Maintenance Required” light on your 2021 Toyota 4Runner is a mileage-based counter designed to remind you that your vehicle is due for an oil change and tire rotation, typically every 5,000 miles. While it is a helpful feature, the light does not automatically turn off after you change your oil; it requires a manual reset through the vehicle’s onboard computer system. This guide covers the exact procedure to clear that notification from your Multi-Information Display (MID). Following these steps ensures your vehicle’s internal tracking remains accurate, helping you maintain the longevity of your engine and stay on top of your warranty-required service intervals. Whether you have a key-ignition or a push-button start model, this walkthrough will help you clear the dash in minutes.

Step 1: Park and Prepare Your Environment

What you need: A safe, level parking area and your vehicle’s ignition key or key fob.

Instructions: Before attempting to interact with the vehicle’s electronic systems, ensure the vehicle is safely parked on a level surface. Shift the transmission into “Park” (P) and engage the emergency parking brake. This is a critical safety measure to ensure the vehicle does not roll while you are focused on the instrument cluster. Additionally, make sure all doors are closed tightly. Many Toyota systems will prioritize “Door Ajar” warnings over the settings menu, which can prevent you from accessing the maintenance sub-menus. Once the vehicle is secured and the cabin is quiet, you are ready to begin the electronic sequence. This preparation ensures that you won’t be distracted or interrupted during the specific timing required for the reset.

Pro Tip: Ensure your headlights are turned off during this process. Keeping the lights on while the engine is off can put unnecessary strain on the battery, especially if you take a few minutes to navigate the menus for the first time.

Step 2: Engage Accessory Power Without Starting the Engine

What you need: Knowledge of your ignition type (Traditional Key vs. Smart Key/Push Button).

Instructions: To access the maintenance menu, the vehicle’s electronics must be active, but the engine should not be running. If your 4Runner uses a standard metal key, insert it and turn it to the “On” position (the second click), which illuminates the dashboard lights. Do not turn it far enough to crank the engine. If you have a Push-Button Start (Smart Key) system, keep your foot completely off the brake pedal and press the “Start” button twice. The instrument cluster should light up, and you should hear the electronic systems hum to life. If the engine starts, you have pressed the brake pedal; turn the car off and try again. The computer will only allow a reset when it is in this specific “Ignition On” mode.

Pro Tip: If the “Maintenance Required” pop-up message appears immediately, you may need to press the “Back” button (usually a small arrow on the right side of the steering wheel) to clear the warning so you can see the main menu icons.

Step 3: Navigate to the Settings Menu via Steering Wheel Controls

What you need: The directional pad (D-pad) located on the right side of your steering wheel.

Instructions: Look at the small digital screen (Multi-Information Display) located between your speedometer and tachometer. Use the left and right arrow buttons on your steering wheel’s D-pad to scroll through the icons at the top of the screen. You are looking for the icon that looks like a small gear or cogwheel, which represents the “Settings” menu. As you toggle through, you will see options for drive info, fuel economy, and compass directions; keep going until the gear icon is highlighted. This menu houses the deeper vehicle configuration settings that are not accessible while the vehicle is in motion. Navigating slowly ensures you don’t overshoot the icon, as the system can sometimes have a slight lag in response.

Pro Tip: If you accidentally enter the wrong menu, simply press the “Back” button (the curved arrow) to return to the top-level icon selection and try again.

Step 4: Locate the Vehicle Settings Sub-Menu

What you need: The center “Enter” or “Dot” button on the steering wheel D-pad.

Instructions: Once the gear icon (Settings) is highlighted, use the down arrow on your D-pad to scroll through the list of sub-menus. You will see options like “LTA” (Lane Tracing Assist) or “PCS” (Pre-Collision System). Continue scrolling down until you find “Vehicle Settings.” It is often near the bottom of the list. Once “Vehicle Settings” is highlighted, press and hold the center “Enter” button (the dot in the middle of the arrows) for about two seconds. This action opens a secondary menu specifically for internal hardware calibrations and maintenance logs. It is important to hold the button rather than just tapping it, as a quick tap may not register the command to enter this specific sub-menu on the 2021 model’s firmware.

Pro Tip: If you find yourself in “Meter Settings” instead, you’ve scrolled too far or not far enough. Exit back out and look specifically for the “Vehicle Settings” text.

Step 5: Select Scheduled Maintenance Reset

What you need: Continued use of the D-pad and center button.

Instructions: Inside the “Vehicle Settings” menu, you will typically see two primary options: “TPMS” (Tire Pressure Monitoring System) and “Scheduled Maintenance.” Use the down arrow to highlight “Scheduled Maintenance.” Press the center “Enter” button once to select it. The screen will then prompt you with a confirmation question, asking something along the lines of “Reset Data?” with “Yes” and “No” options. This is the final gatekeeper before the computer wipes the previous mileage log and starts a new 5,000-mile countdown. Ensure you have actually performed the oil change before confirming this, as resetting it prematurely will result in inaccurate service reminders for the rest of the vehicle’s life.

Pro Tip: On some 2021 trim levels, this might be labeled as “Maintenance Reset” or “Oil Reset.” The process remains identical regardless of the slight variation in terminology.

Step 6: Confirm and Execute the Reset

What you need: A final selection using the D-pad.

Instructions: With the “Reset Data?” prompt on the screen, use the up arrow to highlight the word “Yes.” Once “Yes” is highlighted, press the center “Enter” button one last time. The screen should momentarily display a message that says “Reset Complete” or “Data Has Been Reset.” This confirmation is your signal that the internal clock has been rolled back to zero. Once you see this message, you can release the buttons. The “Maintenance Required” light that previously appeared during startup should now be extinguished. If the screen says “Reset Cancelled,” you likely accidentally hit the “Back” button or selected “No,” in which case you will need to repeat Step 5.

Pro Tip: If the message does not disappear, check if your 4Runner is a Canadian model; sometimes these units require the “Trip A” odometer method instead of the digital menu method, though this is rare for the 2021 model year.

Step 7: Final Verification and Power Cycle

What you need: The ignition key or start button.

Instructions: To ensure the reset has successfully “stuck” in the vehicle’s ECU (Engine Control Unit), turn the ignition completely off. Wait about five to ten seconds for the systems to fully discharge and shut down. Now, start the engine as you normally would (foot on the brake, turn the key or press the start button). Watch the Multi-Information Display during the startup sequence. The “Maintenance Required” warning should no longer appear after the initial system check. If the dash remains clear of the maintenance prompt, the process was successful. At this point, it is a great habit to record the date and current mileage in your physical maintenance logbook or the Toyota App to maintain a secondary record for resale value.

Pro Tip: While you are in the “Settings” menu, take a moment to check your tire pressure readings as well, as these are often adjusted during the same maintenance visit as an oil change.

✅ Final Checklist

• Confirm the “Maintenance Required” text no longer appears on the MID upon engine startup.
• Verify that you selected “Yes” under the “Scheduled Maintenance” sub-menu specifically.
• Ensure the engine was NOT running during the navigation of the settings menu.
• Double-check that you haven’t accidentally reset the TPMS (Tire Pressure) system instead of the oil light.
• Record the current mileage in your service history log for future reference.

Important Notes:

• Safety Warning: This procedure only resets the reminder light; it does not check your oil level or quality. Always physically check your dipstick after an oil change to ensure the engine is properly lubricated.
• Professional Help: If the light returns immediately or if you see a “Low Oil Pressure” warning (a red oil can icon), shut the engine off immediately and consult a professional mechanic, as this indicates a mechanical failure rather than a maintenance reminder.
• Estimated Time: 2–4 minutes.
• Cost Range: $0 (Free DIY task).
