Should You Turn Off the Air Conditioning Before Shutting Down an Automatic Transmission Car?

[MacRafael]

You should turn off the air conditioning before shutting down the car. Here are the relevant details: Reason: The air conditioning relies on the car's battery to operate. If you frequently shut down the car without turning off the air conditioning first, it will not only damage the battery's lifespan but also affect the engine's efficiency. Additionally, it may impact the air quality inside the car and the functionality of the car navigation system. Recommendation: It is recommended to manually turn off the cooling function (indicated by the AC button) a few minutes before shutting down the car, while keeping the air blower running for a while (i.e., do not turn off the air supply). This helps the air conditioning evaporator quickly evaporate the surface moisture as it returns to ambient temperature, preventing the damp surface from becoming a breeding ground for bacteria and thus avoiding unpleasant odors caused by the air conditioning evaporator.
