Keeping accurate records of your maintenance is crucial for tracking your vehicle’s health and maintaining its value.
Resetting the Maintenance Light: The Pedal Dance Method
The most common and straightforward method for resetting the maintenance light on a 5th gen 4Runner involves a series of steps using the accelerator pedal and the ignition switch, often referred to as the “pedal dance.” This method works on most models, but there might be slight variations depending on the specific year of your 4Runner. Here’s how to do it:
Step 1: Ensure the Vehicle is Off
Make sure your 4Runner is completely turned off. The key should be out of the ignition, or if you have a push-button start, ensure the engine is off and the vehicle is in park (P).
Step 2: Turn the Key to the “On” Position (Without Starting the Engine)
Insert the key into the ignition and turn it to the “on” position. For push-button start models, press the start button without pressing the brake pedal. This will activate the electrical system without starting the engine. You should see the dashboard lights illuminate.
Step 3: Press the Odometer Button
Locate the odometer button on your instrument cluster. This is typically a small button labeled “TRIP” or “ODO/TRIP.” Press and hold this button. Do not release it.
Step 4: Turn the Ignition Off
While still holding the odometer button, turn the ignition off. Remove the key from the ignition or, for push-button start models, press the start button to turn off the vehicle.
Step 5: Turn the Ignition Back to the “On” Position
Continue holding the odometer button. Turn the ignition back to the “on” position (without starting the engine).
Step 6: Observe the Reset
Keep holding the odometer button until you see the maintenance light flash and then disappear, or until you see a series of dashes appear on the odometer display, followed by “000000.” This usually takes about 10-15 seconds.
Step 7: Release the Odometer Button
Once the light has reset, release the odometer button.
Step 8: Start the Engine to Confirm
Start the engine to confirm that the maintenance light has been successfully reset. The light should remain off.
If the light is still on, repeat the process carefully. Make sure you are following each step precisely.
