What is the sign that the fuel in the fuel tank reaches the lowest level?

The yellow "refueling light" on the dashboard.

The refueling indicator light is used to remind the driver of the vehicle to refuel the vehicle in time. When the fuel is insufficient, the refueling indicator lights up in yellow. When the fuel is extremely low, the refueling indicator lights up red. However, some models are always flashing yellow, which requires special attention.

Under normal circumstances, when the refueling indicator light is yellow, it is best to refuel the vehicle as soon as possible, and don't wait until the red light is on. This is mainly due to the protection of the oil pump. At present, most gasoline oil pumps need to be immersed in fuel to dissipate heat. If the fuel is insufficient, the heat dissipation effect of the oil pump will obviously decrease, thus accelerating the damage of the oil pump.

Brief introduction of automobile indicator light:

1. Brake warning light: If the brake warning light comes on when the hand brake is released during normal driving, you need to get off the vehicle in time to check the brake oil level to see if the brake oil is insufficient. Once there is a serious shortage of brake oil, you should pay attention to find out whether there is leakage. Because brake oil will not be short of too much in an instant, but the leakage of brake oil will lead to brake failure, so we must be especially careful.

2. Engine fault light: If this warning light is on or the pressure gauge indicates too high, the engine must be turned off. First, check whether the engine oil is missing. The method is to pull out the engine dipstick after the car is turned off and check whether the engine oil page is between the minimum limit and the maximum limit. If the oil level is normal, you should ask the maintenance personnel to check it to determine the cause of the light.

3. Airbag warning light: If the airbag self-test fails after the car is started, the safety warning light will be turned on. At this time, the airbag may not bounce off in the event of an accident, and it will not play a passive protection role. However, the vehicle can still run at this time, so there is no need to worry too much. Just go to the pit as soon as possible.
