What is the solution when the tire pressure warning light stays on?

The solution when the tire pressure warning light stays on is: pull over to check the tire pressure, inflate if the pressure is low, release air if the pressure is high, and promptly replace with a spare tire if there is an issue with the tire. The hazards of excessive tire pressure include: 1. Reduced friction and adhesion of the tire, affecting braking performance and tire lifespan; 2. Decreased puncture resistance, increasing the risk of a blowout; 3. Accelerated wear on the central tread pattern, shortening tire lifespan, increasing vehicle vibration, and affecting the longevity of other components; 4. Excessive stretching and deformation of tire cords, reducing tire elasticity, increasing the load on the vehicle while driving, and decreasing puncture resistance; 5. Increased susceptibility to punctures from nails, glass, and other sharp objects on the road, leading to internal cracks and blowouts under impact.
I usually drive to and from work, and the most annoying thing is when the tire pressure warning light stays on. I encountered this issue last time, and it took me a long time to figure it out. Generally, it could be due to low tire pressure or a faulty system sensor. The solution is quite simple. The first step is to use a tire pressure gauge to check the pressure of each tire—the standard values can be found on the door frame or in the manual. If the pressure is low, use an air pump to inflate them. If the light remains on after inflating, try pressing the reset button in the car, usually located near the steering wheel or on the dashboard. If the light comes back on after resetting, the sensor might be broken, and you’ll need to visit a 4S shop for professional diagnostics. Additionally, tire pressure tends to drop in cold weather, so it’s important to check more frequently in autumn and winter. Don’t try to fix it blindly—if something goes wrong with the tires while driving, it could be a serious problem. Last winter, I forgot to check, and one tire ended up leaking, nearly causing an accident. Now, I’ve made it a habit to check the tire pressure every month.
