What is the reason for the car set light to come on?

[Mitchell]

Car set light comes on reason: It is necessary to check whether the tire pressure is normal. In most cases, when the set light comes on, the tire pressure monitoring warning light on the dashboard will also illuminate. Most cars equipped with tire pressure monitoring systems will only issue an alert when the tire pressure is abnormal, but they usually do not display real-time tire pressure data. Some high-end cars can display real-time tire pressure data, as these vehicles are generally equipped with tire pressure monitoring sensors inside all four wheel rims. After the driver confirms that the tire pressure is insufficient and reinflates the tires, they should press and hold the set button to turn off the tire pressure monitoring warning light on the dashboard. Tires are the only components of a car that come into contact with the ground, making them extremely important for driving safety and stability.
