What to Do When the Tire Pressure Monitoring Light Comes On?

The tire pressure monitoring system warning light coming on indicates a potential issue. You can pull over to check if the situation is minor and resolve it yourself. If the problem is severe, drive slowly to the nearest 4S shop for assistance. Below are some tire-related precautions: Inflation: In winter, car owners should appropriately increase tire inflation pressure to reduce tire wear and consumption. However, if the road is icy and slippery, excessive tire inflation pressure can negatively affect the tire's grip. Potholes: When a tire runs over a pothole, it gets squeezed. The larger the pothole and the higher the speed, the greater the squeezing force on the tire, which can lead to tire bulges. Temperature: When measuring tire pressure in winter, do so after the car has been driven for a while and the tires have cooled down. It’s best to measure at room temperature.
That sudden illumination of the tire pressure warning light really gave me a scare, especially while driving at night on the highway. I immediately hit the brakes and gradually pulled over, not daring to continue—low tire pressure increases the risk of a blowout, which is extremely dangerous. Then I took out my phone to check the recommended values, usually found on a label inside the driver's door; mine was 2.3 bar. I found a nearby gas station and used their free pressure gauge to check, and sure enough, both rear tires were down to 1.8. I quickly inflated them to the standard value, started the car, drove for a few minutes, and the light went off. If the light stays on, it might be due to a slow leak from a small nail puncture or a faulty sensor, requiring professional repair. Remember to check your tire pressure every two weeks—buy a portable tire pressure gauge to keep in your car; it's both cost-effective and ensures safety.
When I see the tire pressure warning light on, I usually don't panic immediately—it's most likely just low pressure. I'll find the nearest gas station where they have free tools to check all four tires' pressure myself. If it's below the recommended value—say, 2.2 bar as marked on my car door—I'll inflate them to the proper level. After driving a short distance, the light typically goes off automatically. If not, I'll check for leaks or punctures; a quick visual inspection often reveals issues. I always keep a small tire pressure gauge in my car—it costs just 10 or 20 bucks—so I can check anytime. Also, lower pressure in cold weather is normal, but don't ignore it. Topping up air promptly prevents faster tire wear and increased fuel consumption. Safety first—just don't delay handling it too long.
