Methods to check tire pressure on BMW 5 Series: Using a tire pressure gauge: For BMW 5 Series, manually checking with a tire pressure gauge is the most direct and accurate method. Using BMW 5 Series tire pressure monitoring system: By performing simple operations on the BMW 5 Series onboard computer, you can view the air pressure of all four tires. When any tire's pressure is too low or too high, the dashboard will issue an alert, prompting the owner to conduct necessary checks. This feature is not only convenient but also enhances the vehicle's active safety. Tire pressure warning light: The tire pressure monitoring indicator is a yellow symbol - an irregular circle without a seal mark, with four small spikes at the bottom and an exclamation mark inside. Illumination of the tire pressure monitoring indicator indicates abnormal tire pressure. Abnormal tire pressure generally has the following 3 causes: Abnormal tire pressure: The system typically alerts when pressure is below 1.8bar or above 3.0bar. In this case, tire inspection and pressure adjustment are required. Tire pressure monitoring not reset: After inflating tires, if the tire pressure reset isn't performed promptly, the system continues to display previously recorded data, causing the tire pressure warning light to illuminate. Simply performing a tire pressure reset will resolve this issue. Damaged tire pressure sensor: The tire pressure sensor, which monitors tire pressure, is installed inside the tire and connected to the tire inflation valve. If the sensor is damaged by impact while driving, it can also trigger the tire pressure warning light. For sensor damage issues, the only solution is to replace it with a new component.
