The 2018 Toyota Highlander is a versatile midsize SUV that offers a comfortable ride and ample space for families. One crucial aspect of vehicle maintenance that often gets overlooked is tire pressure. Proper tire pressure is essential for safety, fuel efficiency, and overall vehicle performance. Understanding the recommended tire pressure for different trims and engines of the Highlander is vital for maintaining optimal driving conditions.
Maintaining the correct tire pressure not only ensures safety but also extends the life of your tires. Under-inflated tires can lead to poor handling and increased tire wear, while over-inflated tires can cause a harsh ride and reduce traction. Below is a detailed table that outlines the recommended tire pressure for various trims and engines of the 2018 Toyota Highlander.

2018 Toyota Highlander Tire Pressure Sensor Reset
When the tire pressure monitoring system (TPMS) light on your 2018 Toyota Highlander starts flashing, it indicates that there is an issue with the tire pressure sensors. This could be due to low tire pressure, a malfunctioning sensor, or the need to reset the system after adjusting tire pressures. Resetting the tire pressure sensor is a straightforward process that can be done in just a few steps.
Steps to Reset Tire Pressure Sensor
- Check Tire Pressures: Ensure all tires are inflated to the recommended PSI.
- Turn on the Ignition: Insert the key and turn it to the “ON” position without starting the engine.
- Locate the TPMS Reset Button: This is usually found under the steering wheel or in the glove compartment.
- Press and Hold the Reset Button: Hold the button until the TPMS light blinks three times, then release it.
- Start the Engine: Turn the ignition off and then start the engine to complete the reset.
Tire Pressure Monitoring System Light Issues
If the TPMS light continues to flash after resetting, further investigation is necessary. Below are common issues that may cause the light to remain on:
| Issue | Possible Solution |
|---|---|
| Low Tire Pressure | Inflate tires to the recommended PSI. |
| Faulty Tire Pressure Sensor | Replace the faulty sensor. |
| TPMS System Malfunction | Consult a professional mechanic for diagnostics. |
| Recent Tire Rotation | Reset the TPMS after rotating tires. |
Understanding the TPMS Light
The TPMS light can indicate various conditions. It’s essential to differentiate between a steady light and a flashing light:
- Steady Light: Indicates low tire pressure in one or more tires.
- Flashing Light: Indicates a malfunction in the TPMS or a sensor issue.
Properly addressing the TPMS light and understanding how to reset the tire pressure sensor can enhance your driving experience and ensure safety on the road.
Maintaining Proper Tire Pressure
Proper tire pressure is crucial for the performance, safety, and efficiency of your 2018 Toyota Highlander. Maintaining the correct tire pressure not only enhances fuel economy but also ensures optimal handling and extends the lifespan of your tires. Under-inflated tires can lead to increased rolling resistance, reduced traction, and higher wear rates. Conversely, over-inflated tires can cause a harsh ride and decrease the tire’s contact with the road, impacting performance and safety.
Benefits of Proper Tire Pressure
- Improved Fuel Efficiency: Properly inflated tires reduce rolling resistance, leading to better gas mileage.
- Enhanced Safety: Correct tire pressure improves vehicle handling and braking performance.
- Extended Tire Life: Maintaining the right pressure prevents premature tire wear and extends their lifespan.
- Better Ride Comfort: Proper inflation contributes to a smoother and more comfortable ride.
How to Check Tire Pressure
Checking tire pressure is a simple task that can be done at home or at a gas station. Follow these steps for accurate measurements:
- Gather Tools: You will need a tire pressure gauge, which can be digital or manual.
- Check When Cold: Measure tire pressure when the tires are cold, ideally before driving or at least three hours after driving.
- Remove Valve Cap: Unscrew the valve cap from the tire you want to check.
- Press Gauge onto Valve: Firmly press the tire pressure gauge onto the valve stem to get a reading.
- Read the Measurement: Note the PSI reading on the gauge and compare it to the recommended pressure for your Highlander.
- Replace Valve Cap: After checking, replace the valve cap securely to prevent dirt and moisture from entering.
Useful Tips for Tire Pressure Maintenance
To ensure your tires remain in optimal condition, consider the following recommendations:
- Regular Checks: Check tire pressure at least once a month and before long trips.
- Use the Right PSI: Always refer to the owner’s manual or the sticker inside the driver’s side door for the correct tire pressure.
- Inspect Tires for Damage: Look for signs of wear, cracks, or punctures that may affect tire pressure.
- Monitor Temperature Changes: Tire pressure can fluctuate with temperature changes; check pressure during seasonal transitions.
- Consider a TPMS: If your Highlander is equipped with a Tire Pressure Monitoring System, pay attention to alerts and address issues promptly.
By understanding the importance of maintaining proper tire pressure and following these guidelines, you can enhance the safety, efficiency, and performance of your 2018 Toyota Highlander.
