What are the reasons for displaying abnormal tire pressure?

[HarleyRose]

The reason for displaying abnormal tire pressure is: at least one of the vehicle's four tires has a pressure lower than the standard value, indicating an underinflated state that requires storing the tire pressure. Tire pressure refers to the air pressure inside the tire. The methods to cancel the abnormal tire pressure warning light are: 1. Turn on the instrument power and press and hold the reset button until the tire pressure warning light turns off; 2. Press and hold the reset button until the tire pressure warning light flashes three times and then turns off. The hazards of abnormal tire pressure include: 1. Increased friction coefficient with the road surface, leading to higher fuel consumption; 2. Creating unsafe factors such as a heavy steering wheel and tendency to veer off course; 3. Increasing the movement of various parts of the tire, causing abnormal heating due to excessive rolling; 4. Multiplying the friction between the tire and the ground, leading to a tire blowout.
