What does it mean when the car's set light stays on?

[DeJourney]

Set is the tire pressure monitoring light. If the vehicle's set light stays on, it indicates a tire pressure alarm, and the tire pressure needs to be stored. More information about the tire pressure monitoring light (Set) is as follows: 1. Tire pressure monitoring automatically checks the tire pressure in real time while the vehicle is in motion, alerting the driver to leaks or low pressure to ensure driving safety. 2. If the tire pressure system alarm is triggered, pull over and check the tire pressure of all four tires. If no obvious loss of pressure is visible, you can ignore it, reset the tire pressure system in the car, and continue driving once the warning light goes off. If the tire pressure warning light comes on again, it means there is an issue with one of the tires, and it should be inspected and repaired promptly. 3. If the tire pressure monitoring system warning light comes on while driving, reduce speed, avoid sharp steering and sudden braking, and check the tires immediately.
