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

[DelAlan]

When a Changan vehicle displays a tire abnormality, it means the tire pressure monitoring system has detected low pressure in one or more tires. In this situation, you should slow down, brake gently to stop safely, avoid sharp turns, and correct the tire pressure when the tires are in a cold state. 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 tire pressure monitoring will then detect the tire abnormality, but it won't display the specific tire pressure, only showing a low tire pressure warning on the dashboard. Direct tire pressure monitoring: This system installs pressure sensors inside or outside the tires, transmitting signals to a receiver that directly provides the tire pressure values on the vehicle's display. This allows drivers to see the pressure information for each tire, making it the more common tire pressure monitoring method in the market today. Direct tire pressure monitoring can be further divided into internal and external types based on the sensor's installation location. Although their positions differ, both internal and external tire pressure monitors operate on the same principle, but their sensors are different. Internal tire pressure monitoring installs sensors inside the tires, while external tire pressure monitoring mounts the sensors on the valve stems.

When I saw the tire warning light come on in my Changan car, my heart skipped a beat because it usually indicates a tire pressure issue, such as low pressure or a leak, which can seriously affect driving stability if left unchecked. I remember just last week when the light suddenly turned on while I was driving on the highway, startling me into pulling over at the nearest service area to check. Sure enough, I found a nail stuck in one tire, causing a slow leak that had been going on for days. This system is called TPMS (Tire Pressure Monitoring System), and its sensors trigger an alert when abnormal tire pressure is detected. I’ve learned it’s important to develop a habit of regularly checking tire pressure, either using a portable air pump or visiting a repair shop for top-ups. Ignoring this warning light can lead to consequences ranging from minor to severe, such as increased risk of a blowout or higher fuel consumption. Now, I always keep a tire pressure gauge handy and check at least once a month to ensure the pressure stays within the recommended range—it’s the only way I can drive with peace of mind.

I think when that warning light comes on, it's alerting me to potential tire issues, commonly low tire pressure, uneven wear, or a faulty sensor. As a dad who frequently travels with family, I take this safety concern very seriously. If there's a tire problem leading to loss of control on the highway, the consequences could be severe. Experience tells me not to panic when the light appears—first, safely pull over and manually check each tire for softness. If it's a sensor issue, restarting the system might clear the light; otherwise, a detailed inspection at the shop is needed, including checking for damage to the rims and tires. I believe regular maintenance shouldn't be neglected either, like checking tire pressure during car washes or installing a real-time monitoring app for convenience. After all, driving safety is no small matter—more prevention means fewer accidents.

Simply put, that indicator light means the tire pressure is below normal or the system detects a leak. Common causes include slow leaks from punctures, seasonal temperature changes affecting pressure, or sensor malfunctions. When the light comes on, I immediately go to a gas station to measure the actual pressure with a tire gauge. If it's below standard, just adding some air will do; otherwise, you'll need to check for damage. Ignoring it not only increases the risk of a blowout but may also accelerate tire wear. I usually keep a portable inflator in the spare tire compartment for quick fixes anytime.
