What is the reason for the yellow exclamation mark appearing on the dashboard?

The reason for the yellow exclamation mark appearing on the dashboard is insufficient tire pressure in one of the tires. It is necessary to check the tire pressure at a tire shop or a 4S store. Tire pressure, strictly speaking, refers to the air pressure inside the tire. Tire pressure is an indicator of a vehicle's load capacity, and the size of the load depends on the level of tire pressure. According to the relationship between the tire's load index, tire pressure, and load capacity, the higher the tire pressure, the greater the load capacity, and the lower the pressure, the smaller the load capacity. For ordinary cars, the front tire pressure is between 2.0 and 2.3 bar, and the rear tire pressure is between 2.2 and 2.5 bar.
When I see the yellow exclamation mark light on the dashboard, I think it's quite common but shouldn't be taken lightly. This light may come on due to low tire pressure, like when the system automatically detects a slow leak in a tire; it could also indicate an engine issue, such as a faulty sensor or emissions system problem triggering the computer to illuminate the yellow light; a warning for the braking system, like an ABS malfunction, may also cause this; in some cars, it might signal a battery or alternator failure. I once had an experience on a long drive where the low tire pressure light came on and nearly caused trouble, but luckily I got it inflated in time. If you see this light while driving, don’t panic—pull over safely to check tire pressure or restart the car. If that doesn’t help, take it to a professional shop to read the trouble codes. Ignoring it could lead to engine damage or tire misalignment, increasing repair costs. Regular car maintenance can reduce such occurrences—simple checks like monitoring tire pressure are easy but effective.
