The 2017 Toyota Highlander features a Tire Pressure Monitoring System (TPMS) designed to alert drivers when tire pressure is low. This system is crucial for maintaining vehicle safety and performance, making it essential for Highlander owners to understand how to access and interpret tire pressure information.

Understanding the Tire Pressure Monitoring System (TPMS)

The TPMS in the 2017 Highlander utilizes sensors installed in each tire to monitor air pressure and temperature. These sensors communicate wirelessly with the vehicle's onboard computer, which displays tire pressure readings on the dashboard. If tire pressure falls below a predetermined threshold, a warning light illuminates on the instrument panel.

Important Info: The TPMS can only function correctly if tire pressures are set within the specified range. If the system is initialized without proper tire inflation, it may not provide accurate warnings.

Accessing Tire Pressure Information

To view tire pressure readings, drivers can use several methods:

  • Multi-Information Display: This is typically found on the dashboard. By navigating through the display options using steering wheel controls, drivers can find real-time tire pressure information for each tire.

  • Tire Pressure Warning Light: If this light illuminates, it indicates that one or more tires are under-inflated. It’s important to check pressures immediately.

  • Toyota App (if subscribed): For those with an active service subscription, the Toyota app can provide tire pressure readings remotely.

Important Info: Always ensure that your tires are inflated to the recommended PSI as indicated on the driver’s side door jamb sticker before resetting or initializing the TPMS.

Resetting the TPMS

If you have recently changed tires or adjusted their pressures, you may need to reset the TPMS. Here’s how:

1. Set all tires to the recommended cold pressures.

2. Turn the ignition ON (but do not start).

3. Press and hold the tire pressure warning reset switch until the warning light blinks three times.

4. Turn off the ignition.

5. Drive for approximately 20 minutes to allow the system to recalibrate.

This process ensures that the system recognizes new tire pressures and functions accurately.

Common Issues and Troubleshooting

If your TPMS light remains illuminated or if dashes appear instead of pressure readings, consider these troubleshooting steps:

  • Check Tire Pressures Manually: Use a reliable gauge to confirm that all tires are properly inflated.

  • Reinitialize System: Follow the reset procedure above to ensure that all sensors are calibrated correctly.

  • Consult a Professional: If problems persist, there may be issues with the sensors or other components of the TPMS that require professional diagnosis.
