What does it mean when the 'set' light on the car dashboard is on?

When the 'set' light on the car dashboard is on, it refers to the tire pressure warning system, which alerts the driver to the need to replenish tire pressure. The tire pressure warning system can automatically monitor the condition of the tires in real-time by recording the rotation speed of the tires or through electronic sensors installed in the tires, providing effective safety protection for driving. Tire pressure monitoring systems are divided into: 1. Indirect tire pressure monitoring system: This system uses the car's ABS anti-lock braking system to compare the speed differences between tires to achieve the purpose of monitoring tire pressure; 2. Direct tire pressure monitoring system: This system uses pressure sensors installed on the tires to measure the tire pressure and temperature, displaying the tire pressure data.
