What does LO mean in car air conditioning?

[KathrynDella]

LO in car air conditioning represents the maximum cooling mode. Car air conditioning modes: LO in car air conditioning stands for maximum cooling. When the vehicle's air conditioning panel displays LO, it indicates that the air conditioning is currently operating at its lowest temperature cooling state, with the system working at full capacity to cool. On the other hand, HI is the abbreviation for 'high' in English. When the panel displays HI, it means the air conditioning is operating at maximum heating capacity, typically at 30 degrees Celsius. In this mode, the system transfers heat from the engine coolant into the vehicle interior. Precautions for using air conditioning: If the vehicle is in a cold start state, heating performance may be affected. Heating will return to normal once the engine coolant temperature rises. Avoid resting in the car with the air conditioning on while the engine is idling. During engine operation, incomplete combustion of gasoline in the cylinders can produce high concentrations of carbon monoxide, leading to potential poisoning hazards.
