3. How To Check Tire Pressure Manually On Your 2021 Toyota Highlander?

Checking your tire pressure manually is a simple process that requires only a few minutes and a reliable tire pressure gauge.

3.1. Tools You’ll Need

Tire Pressure Gauge: You can use either a digital or analog tire pressure gauge. Digital gauges often provide more precise readings.
Gloves (Optional): To keep your hands clean.
A Rag (Optional): To wipe off any dirt or debris from the tire valve.

3.2. Step-By-Step Guide To Checking Tire Pressure

Park Your Vehicle: Park your 2021 Toyota Highlander on a level surface.
Locate the Tire Valve: Remove the valve cap from the tire. Store the cap in a safe place to prevent losing it.
Apply the Gauge: Press the tire pressure gauge firmly onto the valve stem. You should hear a brief hiss of air as the gauge makes a seal.
Read the Gauge:
- Digital Gauge: The reading will appear on the display screen.
- Analog Gauge: Read the pressure indicated by the sliding bar.
Compare to Recommended Pressure: Compare the reading to the recommended tire pressure found on the tire placard or in your owner’s manual.
Adjust if Necessary:
- If the Pressure Is Too Low: Use an air compressor to add air until you reach the recommended pressure. Check the pressure again after adding air.
- If the Pressure Is Too High: Press the metal pin in the center of the valve stem to release air until you reach the recommended pressure. Check the pressure again after releasing air.
Replace the Valve Cap: Once the tire pressure is correct, replace the valve cap securely.
Repeat for All Tires: Repeat this process for all four tires and the spare tire, if applicable.

3.3. Tips For Accurate Readings

Check When Tires Are Cold: Tire pressure increases with heat, so check your tires when they are cold (i.e., before driving or after the vehicle has been parked for at least three hours).
Use a Reliable Gauge: Ensure your tire pressure gauge is accurate by comparing it with another gauge or having it calibrated.
Check Regularly: Make it a habit to check your tire pressure at least once a month and before long trips.

4. How To Use The Tire Pressure Monitoring System (TPMS) On Your 2021 Toyota Highlander?

Your 2021 Toyota Highlander is equipped with a Tire Pressure Monitoring System (TPMS), which alerts you when the tire pressure is significantly low.

4.1. Understanding TPMS

Purpose: TPMS continuously monitors the air pressure in your tires and alerts you if it drops below a certain threshold.
How It Works: Sensors in each tire measure the pressure and transmit the data to the vehicle’s computer.
Warning Light: If the tire pressure is too low, the TPMS warning light will illuminate on your dashboard.

4.2. Locating The TPMS Warning Light

The TPMS warning light is typically located on the instrument panel and looks like a horseshoe symbol with an exclamation point inside. When this light comes on, it indicates that one or more of your tires may be significantly underinflated.

4.3. Resetting The TPMS After Inflation

After inflating your tires to the recommended pressure, the TPMS light may not immediately turn off. Here’s how to reset it:

Drive the Vehicle: Drive your 2021 Toyota Highlander for a few minutes at a speed above 25 mph. This allows the TPMS sensors to recalibrate.
Check the Light: After driving, the TPMS light should turn off. If it doesn’t, there may be a problem with one of the sensors, and you should consult a professional.
Manual Reset (If Necessary): Some models may require a manual reset. Consult your owner’s manual for specific instructions on how to reset the TPMS manually.
