What are the warning lights on the new Passat?

New Passat commonly has four warning lights: tire pressure warning light, coolant temperature indicator, oil pressure warning light, and brake system warning light. Tire pressure warning light: Used to indicate tire pressure. Coolant temperature indicator: Displays engine coolant temperature. When the temperature is too high, the vehicle should not continue driving. Oil pressure warning light: The symbol resembling a teapot is the oil pressure warning light, which novice drivers must understand. These indicators are generally integrated on the car's dashboard. If any light illuminates, it indicates a system malfunction, requiring the driver's attention and prompt repair.
I've been driving the new Passat for two years and have encountered warning lights several times. The most common is the yellow engine symbol, which once flashed due to poor fuel quality; the orange EPC light indicates an electronic system issue, which I experienced after driving through water; the thermometer icon signals coolant overheating, often triggered in traffic jams; the red oil can light is extremely dangerous—I heard of a case where someone kept driving with leaking oil, leading to engine seizure. The tire pressure light is the most unpredictable—it didn’t light up when I had a nail puncture but suddenly alerted when the weather turned cold. By the way, during the power-on self-check, all lights illuminate for a few seconds before turning off. If any stay on, check the manual immediately.
Last week, three warning lights appeared on my Passat's dashboard: the red battery light with a triangle was on, and it was fixed after replacing the battery; the flashing brake light was due to a dirty sensor; the most alarming was the airbag deployment symbol, which turned out to be just a loose wire under the seat. These lights are color-coded, with red, yellow, and green indicating different levels of urgency. I recommend keeping an OBD scanner in the car—just plug it in to read the fault codes, which is more convenient than visiting the dealership. The tire pressure light is the most sensitive and needs resetting with different loads. Remember, don't panic when a light comes on—first, pull over safely and check.
