What does the yellow triangle exclamation mark on Tesla's dashboard mean?

Tesla dashboard yellow exclamation mark light is the tire pressure warning light, which indicates abnormal tire pressure in one or more tires. Possible causes include a punctured tire, excessive tire pressure, prolonged driving with low tire pressure, or a malfunctioning tire pressure sensor. The details are as follows: Punctured tire: This situation usually involves very slow air leakage. If you cannot determine which tire is leaking, you can measure it with a tire pressure gauge. The front tires are generally 2.3bar, and the rear tires are generally 2.5bar. If there is insufficient air, you need to replenish it and then observe the tire pressure warning light. If it lights up again after a few days, you need to drive to a 4S store for repair. Excessive tire pressure: Car tires have specific inflation pressure requirements. Standard tires: 2.4-2.5bar; reinforced tires: 2.8-2.9bar; the maximum pressure should not exceed 3.5bar. Therefore, when a tire's pressure exceeds 3.0bar, the tire pressure warning light will be triggered. In this case, you can release some air to normalize the tire pressure. Prolonged driving with low tire pressure: This usually occurs when a tire's pressure is too low, causing the tire temperature to rise during high-speed operation, which in turn increases the tire pressure. In this situation, you should stop and rest or replace the spare tire promptly. Malfunctioning tire pressure sensor: The tire pressure sensor itself may malfunction, causing the tire pressure light to illuminate. You can use a diagnostic tool to read the fault code and then determine which tire pressure sensor is faulty by replacing the fault code.
