What does the yellow exclamation mark light in the car mean?

The yellow exclamation mark light in the car indicates that there is a problem with a certain part of the vehicle. At this time, switching the display information on the trip computer screen can show specific details. There are many warning or fault lights with an exclamation mark on the dashboard, such as the transmission fault light, power steering fault light, and brake system fault light. When a warning light or fault light illuminates on the car's dashboard, it is essential to inspect and repair it promptly; otherwise, a minor issue may lead to a more significant problem. If the automatic transmission fault warning light comes on, it indicates a fault in the transmission, the transmission lubricant is below the normal range, or the lubricant needs to be replaced. The traction control fault light reminds you to turn off the traction control system. If this light comes on and stays lit while the traction system is active, it indicates a problem with the TCS.
My car recently had this yellow exclamation mark light come on, and honestly, I was a bit panicked at the time. After checking the manual, I realized it was the tire pressure warning signal, indicating there might be an issue with the tire pressure. I immediately pulled over to inspect the tires and found that the right front tire was noticeably low on air—it turned out a small nail had punctured it. If not addressed promptly, driving on the highway could have led to a tire blowout. Nowadays, most cars come standard with tire pressure monitoring, and this light is most likely to be triggered during winter temperature drops. I recommend keeping a portable air pump in the car for emergencies to add some air before driving to a repair shop for a thorough check. Remember, if you see this light, don’t force the car to keep driving—especially in the summer heat, it’s even more dangerous, as abnormal tire conditions can lead to increased fuel consumption or even loss of control.
