What to Do When the Tire Pressure Monitoring Warning Light Comes On?
2 Answers
The solution when the tire pressure monitoring warning light comes on is: Stay calm, do not panic, immediately reduce your speed and avoid sharp steering or sudden braking, then pull over to check the tires. If you have a portable inflator or tire pressure gauge, you can move to the roadside to measure and adjust the pressure in each tire; if not, drive slowly to the nearest auto repair shop or 4S store for servicing. The functions of tire pressure monitoring are: 1. To alert the driver promptly when there are signs of tire danger, prompting them to take appropriate action to prevent serious accidents; 2. To ensure tires operate within the specified pressure and temperature range, reducing damage and extending their service life.
Once while driving on the highway, my tire pressure monitoring light suddenly came on, which really scared me. I immediately slowed down and pulled over, then used the onboard tire pressure gauge to check each tire's pressure one by one. I found the left front tire was only at 2.0 bar, below the standard 2.5 bar, so I quickly inflated it using a portable air pump. After the light went off, I continued driving without issues. Since then, I've developed a habit: checking tire pressure monthly with a digital gauge against the values marked on the door. If the light comes on but the pressure is normal, it might be a faulty sensor or system error—don't try to fix it yourself, go straight to a repair shop for diagnosis. Sensor batteries typically last 5-6 years and aren't expensive to replace. Remember, incorrect tire pressure affects braking distance and fuel efficiency, and can even cause blowouts—never compromise on safety. Keeping a tire pressure gauge in your car is extremely practical for handling situations calmly.
