Opening method of automobile warm air;

After the car starts, after about 8- 15 minutes, the water temperature rises to normal temperature, and the warm air can be turned on at this time. (that is, when the water temperature rises to the middle), adjust the circulation mode of the air conditioner to the in-vehicle circulation and to the warm air mode. Some cars are in the red area, and some cars are indicated by the sun, so don't turn on the air conditioner (don't turn on the AC switch), because the warm air uses the thermal cycle of the car itself to save energy, and the gear of the air conditioner is suitable for gear adjustment. Adjust the wind direction of the air outlet. The direction of warm wind blowing is generally forward and underfoot blowing, and the direction of cold wind blowing is generally forward.
