How to Turn on the Heating in a BMW Car?

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.
When using the air conditioning for warm air, I always consider safety factors. After starting the car, observe the water temperature to ensure the engine is functioning properly before turning the temperature knob to the warm air mode. Generally, setting it to a moderately high temperature like 24 degrees is sufficient, and lowering the fan speed avoids distracting the driver. Warm air helps with defogging, but adjust the air direction appropriately to avoid blowing directly onto the windshield to prevent dizziness. I've seen friends turn on the warm air without preheating, resulting in uneven heating that affects comfort. It's recommended to check the cabin air filter every quarter to prevent dust buildup that reduces efficiency. Keeping the temperature not too high can save fuel and reduce health issues caused by temperature differences.
