Where to Check the Tire Pressure Monitoring in the 2021 Corolla?
4 Answers
2021 Corolla's tire pressure monitoring can be viewed on the display screen. There are three commonly used methods for tire pressure monitoring: Direct Tire Pressure Monitoring: The direct tire pressure monitoring device uses pressure sensors installed in each tire to directly measure the tire's air pressure. It then transmits the pressure information from inside the tire to a central receiver module via a wireless transmitter, displaying the data for each tire's pressure. The system automatically alerts when the tire pressure is too low or if there is a leak. Indirect Tire Pressure Monitoring: When the pressure in a tire decreases, the vehicle's weight causes the rolling radius of that wheel to become smaller, resulting in a faster rotation speed compared to other wheels. By comparing the differences in rotation speeds between tires, the system monitors tire pressure. Indirect tire pressure alert systems essentially rely on calculating the rolling radius of the tires to monitor pressure. Introduction to Tire Pressure Monitoring System (TPMS): It combines the advantages of both systems mentioned above. Direct sensors are installed in two diagonally opposite tires, along with a 4-wheel indirect system. Compared to using only a direct system, this hybrid system can reduce costs and overcome the indirect system's inability to detect when multiple tires simultaneously have low pressure. However, it still cannot provide real-time data on the actual pressure in all four tires as a direct system does.
When I first drove the 2021 Corolla, I didn't know where to check the tire pressure monitoring either, but I figured it out later. It's mainly displayed on the dashboard screen inside the car: after starting the car, sit in the driver's seat, use the control buttons on the right side of the steering wheel, press the info button to switch to the vehicle information menu, and then look for the tire pressure display section. If the tire pressure is normal, the value will pop up directly, generally a safe range is around 32 to 35 PSI. Why check it? If the tire pressure is too high, the tires wear out faster; if it's too low, fuel consumption increases and there's a higher risk of a flat tire, especially before driving on the highway. It's recommended to glance at the dashboard every time before driving—developing this habit can save a lot of trouble. New drivers don't need to worry, it's simple to operate and can be learned in just a few minutes.
I've been driving this car for almost two years, and the tire pressure monitoring system is very convenient for daily use. It's displayed directly on the multifunction screen in the center of the instrument panel: after starting the vehicle, without moving, press the up and down arrow buttons on the right side of the steering wheel, navigate the menu to the tire pressure option, and the values will appear. If the tire pressure is low, the system icon will light up with a yellow warning. Additionally, it's most accurate to check when the car is cold; readings might be higher when the car is warm. Maintaining proper tire pressure is crucial—it improves grip, reduces noise, and makes long-distance driving more stable. The setup is also user-friendly, as it remembers the settings once configured.
The 2021 Corolla is equipped with a tire pressure monitoring system, and the display location is in the combination meter. The operation is simple: start the engine, after the dashboard lights up, use the steering wheel control buttons to find the settings page, switch to the tire pressure reading, and you can instantly see the pressure values of all four tires. The system automatically monitors and will alert if there is a problem. It is recommended to check regularly, such as before driving in the morning, as tire pressure changes can affect safety and fuel consumption. The reading unit is usually kilograms or PSI, with a general range of 30-35. Don't overlook this small action, as tire health directly affects driving comfort.
