How to Use the Air Conditioning When the Outside Temperature is Lower Than Inside the Car?

[StMartin]

When the outside temperature is lower than inside the car, you should use the external air circulation. Using air conditioning in summer: In summer, the weather is quite hot, and the temperature inside the car is relatively high when you first enter. Although it's hot, it's not recommended to turn on the air conditioning immediately. Instead, it's advisable to open the car doors and sunroof to allow air to circulate for a while before turning on the air conditioning. This not only helps cool down the car quickly but also saves fuel. When the temperature inside the car is higher than outside, it's recommended to use external air circulation. Using air conditioning in winter: During cold winter weather, when the car has just started, do not turn on the air conditioning fan immediately. First, start the engine to warm up. Wait until the engine temperature gauge needle reaches the middle position, then turn on the heating air conditioning. At the same time, set the air circulation to external to allow the cold air inside the car to be expelled. After waiting for 2-3 minutes, you can switch the air circulation to internal.
