What does the appearance of a small blue sailboat on a car indicate?

The dark blue small sailboat on the car dashboard refers to the coolant temperature and level indicator light, which is primarily used to indicate the temperature of the coolant inside the engine. Every time the vehicle is started and undergoes a self-check, the coolant temperature and level indicator light will illuminate for a few seconds before turning off, which is a normal condition. However, if the indicator light remains lit, it indicates that the coolant temperature has exceeded the specified value. In such cases, the vehicle should be stopped immediately to check the engine coolant condition. Possible reasons for the coolant temperature and level indicator light remaining lit: Insufficient antifreeze in the vehicle's engine cooling system, or leaks in the engine such as water pump leaks, pipe damage, or radiator damage. Abnormal operation of the cooling fan in the engine cooling system, leading to poor heat dissipation of the coolant, causing the coolant temperature to exceed the specified value, which triggers the indicator light. Malfunction of the coolant temperature sensor in the engine cooling system, preventing proper operation, which hinders effective coolant flow within the engine, resulting in excessively high coolant temperature and the indicator light remaining lit. Failure of the water pump in the engine cooling system, causing the pump to rotate improperly, which also prevents normal coolant flow, leading to increased temperature and the indicator light remaining lit. Solutions for the coolant temperature and level indicator light remaining lit: Park the vehicle and wait for the temperature to decrease before driving to a maintenance center for repair. If the warning light suddenly flashes while driving, find a safe place to stop immediately without turning off the engine. Excessive temperature can cause the pistons, crankshaft, and other components to overheat simultaneously, thickening the engine oil and leading to cylinder sticking. The correct approach is to temporarily maintain idle rotation and then proceed with cooling measures.
Last time I was driving my friend's Tesla Model S, a blue sailboat icon suddenly popped up on the screen, which gave me quite a scare! Later I figured out it wasn't some nautical signal, but their autopilot system reminding me to stay safe. If you see this, it mostly means the vehicle detected you weren't holding the steering wheel firmly, or the system needs to confirm the driver's attention. This thing is especially common on highways - just gently turn the steering wheel or touch it and it'll disappear. I think this feature is pretty smart for preventing accidents when people get drowsy, but it might be a bit confusing for new drivers. Remember, safety first - if you encounter similar situations, immediately return to manual driving and don't get distracted by checking your phone or other things.
On Tesla vehicles, that blue sailboat icon typically indicates the Autopilot function. When illuminated, it means autonomous driving is activated but the sensors detect insufficient driver attention, prompting you to hold the steering wheel. Having explored the dashboard settings, I can confirm it's a safety mechanism design—using visual and auditory warnings to prevent misuse. During daily driving, it may appear due to changing road conditions or controller neglect; a slight touch to the wheel or pedals will restore control. Overall a well-designed feature, though drivers need to get accustomed to its presence to avoid unnecessary alarm.
