What to do when the TPMS indicator light comes on?
2 Answers
When the TPMS indicator light comes on, the following steps should be taken: 1. Immediately reduce speed and avoid sharp steering or sudden braking, then check tire pressure; 2. If there is a simple inflation tool in the car, you can measure the pressure of each tire and inflate them yourself; 3. If there is no simple inflation tool, drive slowly to the nearest repair shop for inflation. TPMS is the Tire Pressure Monitoring System. This system uses highly sensitive sensors installed on each tire to monitor tire pressure, temperature, and other data in real-time, whether the vehicle is moving or stationary. The data is then transmitted wirelessly to a receiver, which displays various data changes on a monitor or alerts the driver through beeps or other signals.
I've been driving for over a decade and have encountered the tire pressure warning light multiple times. The most important thing is not to panic or push your luck—pull over immediately to check the tires. I always keep a simple tire pressure gauge in my car and measure all four tires. Once during heavy snow, the tire pressure light suddenly came on, and I found a nail causing a slow leak in the right rear tire—thankfully I didn’t keep driving. If you don’t have professional tools, the nearest auto shop can usually check it for free. Remember, the recommended tire pressure is labeled on the door frame, and it’s safer to slightly lower it in summer. After fixing the tire, don’t rush off—ask the mechanic to reset the tire pressure monitoring system, or the light will keep misleading you.
