What does the wavy line under the exclamation mark mean?
1 Answers
The exclamation mark with a wavy line underneath in a car is the tire pressure warning light. Here are the specific reasons why the tire pressure light may illuminate: Punctured tire: You can use a tire pressure gauge to measure. The normal values are 2.3 for the front tires and 2.5 for the rear tires. If the pressure is low, inflate the tire to the proper level and then observe the tire pressure warning light. Overinflated tire: The standard tire pressure is 2.4-2.5 bar; reinforced tires should be 2.8-2.9 bar. The maximum pressure should not exceed 3.5 bar. Therefore, if any tire exceeds 3.0 bar, it may trigger the tire pressure monitoring light. Driving with low tire pressure for too long: This usually occurs when a tire's pressure is too low, causing the tire temperature to rise during high-speed driving, which in turn increases the tire pressure. In such cases, you should stop and rest or replace the tire with a spare one. Long-term underinflation: When the tire pressure drops below 1.8 bar, it may trigger the tire pressure monitoring light. Regular checks should be performed to ensure the tire pressure monitor is functioning correctly. If the tire pressure monitor does not alert you in time when there is an issue, it may indicate a problem with the monitor itself.
