What Causes the Tire Pressure Light to Illuminate?

[Eliana]

The reasons for the tire pressure light illuminating are: 1. A tire puncture caused by a nail; 2. Excessive tire pressure; 3. Driving with low tire pressure for an extended period; 4. Malfunction of the tire pressure sensor; 5. Prolonged lack of air leading to low tire pressure. The tire pressure warning light is designed to indicate the tire pressure status of the vehicle. Under normal circumstances, this indicator remains off. The methods to address the illuminated tire pressure warning light are: 1. Pull over safely, exit the vehicle, and inspect the tire pressure of all four tires. If no obvious loss of pressure is visible, reset the tire pressure system after getting back in the vehicle to turn off the warning light; 2. If the tire pressure warning light comes on again, it indicates an issue with the tire pressure of a specific tire, requiring prompt inspection and repair.
