How to activate the A and M modes in the BMW X1's air recirculation system?

[EmilyLynn]

A stands for automatic mode, and M stands for recirculation mode. Simply press the corresponding button to activate the A mode or M mode. In automatic mode, the car will switch between recirculation mode and fresh air mode based on the quality of the air inside the vehicle. Different situations call for the use of different modes. Here is a detailed introduction to the car's air conditioning system: 1. Overview: The car air conditioning system is a crucial comfort feature in vehicles, used almost daily during both winter and summer. The car air conditioning can provide both heating and cooling. 2. Working principle: When the car air conditioning is cooling, the compressor clutch engages, allowing the engine to drive the compressor. The compressor then continuously compresses the refrigerant and delivers it to the evaporator.
