A yellow light appears on the speedometer?

A yellow light appearing on the speedometer is an automatic transmission warning light, and you should go to a 4S shop or repair shop for inspection as soon as possible. The following are precautions regarding the automatic transmission warning light: 1. Analyze the current situation and do not continue driving blindly to prevent serious damage to the transmission. 2. If the transmission warning light is on but no other abnormalities are found, and the engine speed and vehicle speed are the same as usual, you can continue driving and then arrange to check the cause of the transmission failure as soon as possible. 3. If slipping transmission, transmission not shifting, transmission shifting impact or hesitation, gear engaged but car not moving, or acceleration without movement occurs while driving, you should immediately pull over, turn off the engine, and contact a transmission repair center for rescue and inspection.
Last time I was driving, a yellow warning light suddenly popped up on the dashboard—it was the engine fault light, shaped like a faucet. I felt a bit nervous at the time, but later learned that this is usually a warning signal indicating the car might have minor issues, such as a sensor malfunction or emission system abnormality—not necessarily a major problem. For example, the light can also come on if the fuel cap isn't tightened properly. The key is not to panic: first, slow down and drive steadily, avoiding sudden acceleration or hard braking. Find a safe place to pull over and check the vehicle's condition: ensure the fuel cap is tight, inspect the tires for abnormalities, and listen for unusual engine noises. If everything seems fine, it's still advisable to visit a repair shop as soon as possible to read the fault codes with professional diagnostic equipment for precise troubleshooting. In my case, it was due to a dirty oxygen sensor—after cleaning, the light went off. Regular maintenance, such as changing filters and checking sensors periodically, can help reduce the chances of the yellow light appearing. Remember, the yellow light is the car's way of alerting me to potential risks—addressing it promptly can prevent bigger troubles.
