In this post, we’ll walk you through the steps to reset the oil life indicator on your 2021 Hyundai Sonata.

Step by Step Guide to Reset Oil Life on 2021 Hyundai Sonata

Step 1: Ensure Safety

Before you begin, make sure your car is parked safely in a flat and level area. Turn off the engine, engage the parking brake, and ensure the vehicle is in park (automatic) or in neutral (manual).

Step 2: Access the Dashboard

Once you’re safely parked, get into the driver’s seat and insert the key into the ignition. Turn the key to the “On” position without starting the engine. You should see various warning lights illuminate on your dashboard.

Step 3: Navigate to the Oil Life Screen

On your Sonata’s dashboard, you’ll find a button labeled “Mode” or “Trip.” Press this button repeatedly until you see the “Oil Life” screen displayed on the instrument cluster. This screen will show you the percentage of remaining oil life.

Step 4: Reset the Oil Life

With the “Oil Life” screen displayed, press and hold the “Reset” button. You might need to locate this button near your instrument cluster or on your steering wheel. Hold the button down for approximately 5-10 seconds until you see the oil life percentage reset to 100%.

Step 5: Confirmation

Release the “Reset” button. You should now see the oil life reset to 100% on the dashboard. This indicates that the oil life indicator has been successfully reset.

Step 6: Turn Off the Ignition

Turn the ignition key to the “Off” position. You have now successfully reset the oil life on your 2021 Hyundai Sonata.

How Do You Check the Oil Percentage in Hyundai Sonata 2021?

The Hyundai Sonata, like most modern vehicles, does not have a built-in oil percentage sensor. Instead, it relies on a traditional method of checking the oil level and condition.

Here’s how you can check the oil level in your 2021 Hyundai Sonata:

  1. Park on a Level Surface: Make sure your car is parked on a level surface and the engine is turned off. It’s best to check the oil when the engine is cold or has been off for a while to allow the oil to settle.
  2. Locate the Dipstick: Open the car’s hood and locate the oil dipstick. It typically has a brightly colored handle for easy identification, usually yellow, orange, or red.
  3. Remove the Dipstick: Carefully pull the dipstick out of the engine. Wipe it clean with a paper towel or cloth.
  4. Reinsert the Dipstick: Push the dipstick all the way back into the dipstick tube until it’s fully seated.
  5. Check the Oil Level: Pull the dipstick back out and examine the oil level. There are usually markings on the dipstick indicating the safe range for oil level. It might say “Min” (minimum) and “Max” (maximum). The oil level should be between these two marks. If it’s below the “Min” mark, you’ll need to add oil.
  6. Inspect the Oil Condition: While you have the dipstick out, you can also inspect the oil’s color and consistency. Healthy oil should be amber or brown and not have a burnt smell. If the oil looks very dark or dirty, it may be time for an oil change.
  7. Add Oil (if necessary): If the oil level is below the “Min” mark, you should add oil to bring it to the appropriate level. Refer to your owner’s manual for the type and grade of oil recommended for your vehicle.
  8. Recheck the Oil Level: After adding oil, wait a few minutes for it to settle, and then recheck the oil level to ensure it’s within the safe range.

Remember to always follow the manufacturer’s recommendations in your owner’s manual for checking and changing the oil in your Hyundai Sonata. Regular oil checks and changes are essential for maintaining the health and longevity of your engine.

If you’re not comfortable doing this yourself, you can also take your car to a professional mechanic or an oil change service center to have it checked and serviced.


Regularly changing your oil and resetting the oil life indicator are essential steps in ensuring the health and longevity of your vehicle’s engine. By following these simple steps, you can reset the oil life indicator on your 2021 Hyundai Sonata with ease. However, it’s crucial to consult your owner’s manual or contact your Hyundai dealer if you encounter any difficulties or have specific questions about your vehicle’s maintenance.

Remember that the frequency of oil changes can vary depending on driving conditions and the type of oil you use, so always consult your owner’s manual for the manufacturer’s recommended maintenance schedule. Keeping up with regular oil changes and maintenance is a key part of ensuring your Sonata continues to run smoothly for years to come.
