Resetting the oil life indicator on your 2019 Toyota Highlander is a simple maintenance task that should be performed after each oil change. This feature, designed to help you track the remaining life of your engine oil, ensures that you stay on top of routine oil changes tailored to your driving conditions. Failure to reset the oil life monitor can lead to missed maintenance intervals or unnecessary service appointments. In this comprehensive guide, we’ll walk you through how to reset the oil life system in your 2019 Toyota Highlander using both the driver display and the multifunction trip computer. Whether you perform your own oil changes or bring your vehicle to a service center, this guide will help you effectively manage your maintenance schedule.
Understanding the Oil Life Monitoring System
The 2019 Toyota Highlander is equipped with an advanced Oil Life Monitoring System (OLMS) that estimates when your engine oil needs to be changed based on a combination of driving conditions, engine temperature, RPM, distance driven, and other factors. Unlike traditional fixed-interval oil change schedules (e.g., every 3,000 or 5,000 miles), this system provides a more accurate, vehicle-specific recommendation. As your vehicle drives, it tracks these conditions and reduces the oil life percentage accordingly.
When the oil life indicator reaches 0%, the message “Change Engine Oil Soon” will appear on the dashboard display. It is crucial to change your oil as soon as possible after this message appears. Once the oil is changed, resetting the indicator is essential to ensure accurate tracking for the next interval.
Why Resetting the Oil Life Is Important
Many drivers may not understand the importance of resetting the oil change indicator. If the system isn’t reset after an oil change, it will continue counting down from the previous cycle. This can lead to one of two scenarios:
- Missing an oil change because the indicator never reaches 0%
- Triggering a false “Change Oil” warning too early
These outcomes can reduce engine performance, lower fuel efficiency, and potentially cause premature wear. Therefore, resetting the oil life system helps your vehicle continue to run efficiently, maintain warranty compliance, and avoid unnecessary engine damage.
When Should You Reset the Oil Life on Your 2019 Toyota Highlander?
The oil life system should be reset only after you have completed an oil change. This includes drain, filter replacement, and refill with the correct weight of oil—typically 0W-20 Full Synthetic as recommended by Toyota. Waiting until the system alerts you (“Change Engine Oil Soon” message) is ideal for resetting; however, the system can also be reset manually.
The 2019 Highlander’s oil life system generally recommends changes every 10,000 miles under normal driving conditions, though this can vary based on your driving habits. Frequent short trips, extreme temperatures, or towing can shorten oil life and require more frequent changes.
Driving Conditions and Their Impact on Oil Life
To better understand why the system recommends oil changes at specific intervals, it’s important to know how driving behavior affects oil longevity:
| Driving Behavior | Effect on Oil Life |
|---|---|
| Aggressive Acceleration and Braking | Accelerates oil degradation |
| Short Trips Below 10 Miles | Causes moisture buildup in oil |
| Stop-and-Go Traffic | Increases engine load and oil breakdown |
| Extreme Temperatures (Hot or Cold) | Strains oil performance |
Step-by-Step Guide to Reset Oil Life on the 2019 Toyota Highlander
Now that you understand the system’s purpose and importance, let’s guide you through the straightforward process of resetting the oil life indicator on your 2019 Toyota Highlander using the multifunction trip computer located on the instrument cluster. This process does not require any tools or special equipment—only a few simple steps.
Method 1: Using the Steering Wheel Controls (Trip Computer Method)
This is the most common and recommended method for resetting the oil life. It utilizes the buttons mounted on the steering wheel to interact with the vehicle information display.
Step 1: Turn the Ignition On
With the vehicle off, turn the ignition key to the “On” position (do not start the engine). For push-button start models, press the Start button once without pressing the brake pedal.
Step 2: Access the Multi-Information Display
Use the multi-function selector buttons located on the left side of the steering wheel to scroll through the menu on the driver information display. Typically, this is a round toggle wheel with options like “TRIP,” “RESET,” and others.
Step 3: Navigate to the Oil Life Menu
From the main menu, scroll to and select the option labeled “Maintenance” or “Oil Life.” Some models may label it as “Maintenance System,” which includes oil life and other service indicators.
Step 4: Reset the Oil Life
Once you’re in the Oil Life menu, hold the “Reset” button (usually the center button of the scroll wheel). A confirmation screen should appear asking you to confirm the reset. Follow the on-screen prompts to reset the oil life percentage back to 100%. You might need to hold the reset button for several seconds to complete the process.
Step 5: Confirm the Reset
After the oil life resets, turn the ignition off and then on again to verify that the percentage is now at 100% and the “Change Engine Oil Soon” message is gone. If everything looks good, your Highlander is ready for the next service interval.
Method 2: Using the Driver Information Display
In some 2019 model-year Highlanders, especially those with the Entune infotainment system or advanced driver-assist packages, you may also interact with the oil life monitor via the touchscreen or center console controls. However, this is not standard on all trims. If your vehicle has this option, here’s how it might work:
Step 1: Power On the Infotainment System
Start by turning the vehicle ignition to the “On” position. Then, power on the Entune display system.
Step 2: Access the Vehicle Maintenance Menu
Depending on your system, navigate to the “Settings” or “Control” section. Look for options such as “Vehicle Info,” “Maintenance,” or “Engine Oil Life.”
Step 3: Reset the Oil Life
Select “Reset Oil Life” and follow the on-screen instructions. You may be prompted to confirm that the oil has just been changed.
Note that this second method may not be available on every 2019 Highlander, especially lower trim levels. The first method through the steering wheel and driver information display is universal across all versions.
Troubleshooting Common Issues
If your oil life doesn’t reset properly, try the following tips:
- Ensure that the vehicle is turned “On” but not “Running.”
- Check the battery charge—low battery voltage can affect system resets.
- Try resetting the system before powering off the vehicle to see if the change takes effect.
If you encounter persistent issues or the system is unresponsive, refer to your owner’s manual for your specific Highlander trim or schedule an appointment with a certified Toyota technician.
