What does an exclamation mark with a wavy line underneath mean?

[DiEverly]

An exclamation mark with a wavy line underneath indicates an abnormal tire pressure condition in the vehicle. If this warning light remains illuminated after the vehicle's self-check, it means there is an issue with the tire pressure, and it is necessary to promptly check whether the tire pressure is normal to avoid dangerous situations such as tire blowouts. The effects of abnormal tire pressure include: 1. Increased friction coefficient with the road surface; 2. Steering becomes heavy and prone to deviation, creating unfavorable driving safety factors; 3. Increased movement of various parts of the tire, leading to excessive rolling and abnormal heat generation in the tire. The causes of abnormal tire pressure are: 1. Tire pressure is outside the normal range; 2. Tire leaks or punctures causing insufficient air pressure; 3. Excessive tire pressure. Tire pressure refers to the air pressure inside the tire.
