What does the sun exclamation mark on the dashboard mean?

When this warning light appears on the dashboard, it indicates a transmission malfunction. This warning light is not actually a sun, but rather a gear with an exclamation mark inside. Here are the specific details: Timely inspection: If this warning light appears on the dashboard while driving, it is recommended that the owner promptly take the vehicle to a repair shop for inspection. Automatic transmissions come in various types and are prone to many different malfunctions, so it is necessary to visit a 4S shop or repair shop for timely inspection. Transmission overheating: For vehicles equipped with a dry dual-clutch transmission, this warning light may indicate transmission overheating. In stop-and-go traffic, the dry dual-clutch transmission is particularly susceptible to overheating. Stop-and-go situations: During traffic congestion, frequent stopping and starting causes the transmission to repeatedly shift between 1st and 2nd gears. For dual-clutch transmissions, this means the two sets of clutches are constantly engaging and disengaging, which can easily lead to transmission overheating. Dry dual-clutch transmissions rely on air for cooling, and slow-moving traffic reduces the cooling efficiency of the transmission.
I've been driving for over a decade and have encountered this sun exclamation light several times. When it illuminates on the dashboard, it usually indicates that the engine hasn't fully warmed up yet—it's a cold engine warning light. Especially when starting on cold winter mornings or in low temperatures, the car is reminding you not to rush into speeding; you should drive at low speed for a while first. If you accelerate immediately, engine wear will be more severe, and fuel consumption will also increase. I remember one time I ignored it, and right after getting on the highway, I felt the engine shaking. The repair shop said it might be a thermostat issue. So, I recommend that after each start, you should shift to a low gear and cruise slowly for a few minutes, waiting for the light to go off before accelerating. Regular maintenance should also focus on the cooling system, ensuring sufficient antifreeze to avoid winter troubles. These experiences have saved me a lot on repair costs.
As a new car owner, the first time I saw a sun with an exclamation mark icon on the dashboard, I almost called for a tow truck. It actually indicates that the engine temperature is too low, which is common shortly after starting the car. Especially on cold mornings after ignition, the light means the engine hasn't warmed up yet and needs preheating. My approach is to let the engine idle for half a minute after starting, then gently press the accelerator and drive at low speed for a few minutes. When the light goes off, it means the engine has reached normal operating temperature. This practice helps protect the engine, reduces wear, and saves fuel. Additionally, developing a habit of regular checks is important, such as monitoring oil and coolant levels. After learning these tips, new drivers can feel more at ease behind the wheel without unnecessary worries.
