What does the abnormal tire warning light on Changan vehicles mean?

[McAlex]

When a Changan vehicle displays a tire abnormality, it means the Tire Pressure Monitoring System (TPMS) has detected low pressure in one or more tires. In this situation, you should slow down, brake gently to stop safely, and avoid sharp turns. Correct the tire pressure when the tires are in a cold state. Below is an introduction to tire pressure monitoring: Indirect Tire Pressure Monitoring: This system uses speed sensors on the vehicle's wheels to compare the rotation counts of all four tires. If one tire has lower pressure, its rotation count will differ from the others during driving. The indirect TPMS will then detect the tire abnormality but will not display the specific pressure; it will only indicate low tire pressure on the dashboard. Direct Tire Pressure Monitoring: This system involves installing pressure sensors inside or outside the tires. The sensors transmit signals to a receiver, which directly displays the tire pressure values on the vehicle's screen. This allows drivers to view the pressure information for each tire, making it a widely used TPMS method in the market. Direct TPMS can be further categorized into internal and external types based on the sensor's installation location. Although the installation positions differ, both internal and external TPMS operate on the same principle, though their sensors vary. Internal TPMS installs the sensor inside the tire, while external TPMS mounts it on the valve stem.
