How to Check Tire Pressure Monitoring on the 2021 Sagitar?
2 Answers
2021 Sagitar's tire pressure monitoring is automatic. If the tire pressure is insufficient or the tire is punctured or impacted, a tire pressure warning will appear on the dashboard. Introduction to Tire Pressure Monitoring: Tire pressure monitoring automatically monitors the tire pressure in real-time during driving and alerts the driver in case of tire leaks or low pressure to ensure driving safety. There are three common types of tire pressure monitoring: Direct Tire Pressure Monitoring: Direct tire pressure monitoring devices use pressure sensors installed in each tire to directly measure tire pressure. The pressure information is transmitted wirelessly from inside the tire to a central receiver module, which then displays the tire pressure data for each tire. The system automatically alerts the driver if 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 other wheels. By comparing the differences in rotation speeds between tires, the system monitors tire pressure. Indirect tire pressure monitoring systems essentially rely on calculating the rolling radius of the tires to monitor pressure. Introduction to Tire Pressure Monitoring System (TPMS): TPMS combines the advantages of both systems mentioned above. It is equipped with direct sensors in two diagonally opposite tires and an indirect system for all four wheels. Compared to a fully direct system, this hybrid system reduces costs and overcomes the limitation of indirect systems, which cannot detect simultaneous low pressure in multiple tires. However, it still cannot provide real-time pressure data for all four tires as effectively as a direct system.
As a car enthusiast, I know the 2021 Sagitar uses an indirect tire pressure monitoring system. It relies on ABS sensors to detect abnormal tire pressure by monitoring changes in wheel rotation speed, without displaying specific values—only providing an alert. Checking it is actually quite simple: after starting the car, press the VIEW button on the steering wheel to enter the instrument menu settings, and look for a small tire-like icon—that's the tire pressure monitoring option. If the system is functioning normally, it will remain green; if an alert is triggered, a warning light will illuminate on the dashboard, prompting you to pull over and manually check tire pressure and condition. Sometimes, the system may give false alarms, such as after inflating or changing tires, requiring a reset—just press and hold the OK button on the steering wheel for a few seconds to initialize. Tire pressure monitoring helps prevent blowouts and saves fuel. I make it a habit to check tire pressure whenever I wash my car, as this practice enhances driving safety.
