What does L0 mean in car air conditioning?

[SanClara]

Car air conditioning L0 indicates the lowest temperature. When adjusting the car air conditioning temperature and L0 appears, it means the current setting is at the minimum temperature. The air conditioning may also display HI and ME markings, representing high temperature and medium temperature respectively. L0 stands for the English word 'Low', while HI stands for 'High'. Below are the correct usage methods for car air conditioning: 1. The blue button on the left represents cold air, the red button on the right represents warm air, and the middle button represents moderate temperature. 2. To activate cold air, adjust the left button towards the blue zone; for warm air, adjust towards the red zone, then press the AC switch. The middle button controls fan speed. 3. The white line on the left adjusts temperature; if it feels too warm, simply adjust it to the middle position.
