Does the Hongqi HS5 turn on the heater without using the air conditioning in winter?

You don't need to turn on the AC switch when using the car's heater. Increasing humidity with the heater: After running the heater for a while, you may noticeably feel dry mouth and discomfort while breathing. This is because the air is already very dry in northern winters, and using the heater in a closed environment exacerbates the dryness. This issue can be resolved by slightly opening the window for ventilation. Of course, there are other options, such as using a car humidifier or hanging a wet towel in the car, which can also provide good humidification effects. Setting the right airflow direction for the heater: When using the heater, you should follow the principle that cold air sinks and hot air rises. In winter, adjust the airflow direction to blow towards your feet. This way, you won't feel noticeably stuffy while breathing and can still achieve excellent heating effects.
