How to Turn on the Heating in a BMW Car?
2 Answers
To turn on the heating in a BMW car, follow these steps: 1. First, turn the knob below the air vent to the red position. 2. Then, increase the temperature and select an appropriate fan speed. Set the air circulation to external circulation for about 3 minutes to expel the cold air inside the car and bring in fresh air from outside. 3. Switch the air circulation to internal circulation, adjust the fan speed and direction, set the air conditioning to a suitable gear, and adjust the air vent direction. Generally, the warm air should blow forward and toward the feet. Here is some additional information about car heating: 1. Do not press the AC button when using the heating. The AC button is the cooling switch for the car's air conditioning. Pressing the AC button engages the compressor clutch, causing the engine to drive the compressor, which continuously compresses refrigerant and delivers it to the evaporator. 2. The car's heating system utilizes the engine's heat. The principle of car heating is very simple: during heating, high-temperature coolant from the engine flows through the heater core, and the air blown by the fan passes through the heater core, allowing warm air to be blown out from the air vents.
Turning on the heating in a BMW is actually quite simple. When I drive, I usually like to start the engine first and let it warm up for a minute or two before operating the system once the temperature gauge rises. On the center console, locate the temperature control knob—the one with the red and blue zones—and turn it toward the red side for heat. If your car has an AUTO button, pressing it will automatically adjust the fan speed and temperature to the set value, such as the 22°C I often use, which feels very comfortable. Don’t forget to adjust the fan speed to a moderate level to avoid excessive noise. Airflow direction is also important—I recommend directing it toward the feet or the windshield to prevent fogging. In winter, be careful not to let the cabin get too stuffy; crack a window occasionally for ventilation. For long-term use, remember to regularly check the coolant level to ensure the air conditioning system functions properly.
