How to Check the Tire Pressure Monitoring in the 2021 Hyundai Elantra?
2 Answers
The tire pressure monitoring in the 2021 Hyundai Elantra can directly display the tire pressure values on the vehicle's screen. There are three common methods of tire pressure monitoring: Direct Tire Pressure Monitoring: Direct tire pressure monitoring devices use pressure sensors installed in each tire to directly measure the tire pressure. The pressure information is transmitted wirelessly from inside the tire to a central receiver module, which then displays the pressure data for each tire. 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 tire to become smaller, resulting in a faster rotation speed compared to the other wheels. By comparing the differences in rotation speeds between the tires, the system monitors the tire pressure. Indirect tire pressure warning 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 the above systems. Direct sensors are installed in two diagonally opposite tires, and a four-wheel indirect system is also equipped. Compared to a fully direct system, this hybrid system reduces costs and overcomes the limitation of indirect systems, which cannot detect when multiple tires simultaneously have low pressure. However, it still cannot provide real-time pressure data for all four tires as a direct system does.
I've been driving the Elantra for over a year, and the tire pressure monitoring is quite straightforward. After starting the vehicle, observe the central dashboard display screen. Use the up and down arrow keys on the right side of the steering wheel to navigate through the menu and locate the 'Tire Pressure' option. The real-time pressure values for all four tires will be displayed on the screen, with values below the standard turning yellow as a warning. The standard tire pressure when the car is cold is around 230 kPa, but check the label on the driver's door frame for specifics. After highway driving, the pressure may increase by 10-20 kPa, which is normal. If you notice a significant drop in pressure in one tire, it's likely due to a puncture. Get it repaired promptly instead of waiting for the warning light to come on.
