How to Turn on the Cold Air in BMW 3 Series?
2 Answers
Inside the BMW 3 Series, there is a large circular knob on the center console. Blue represents cold air, red represents warm air, and the middle position represents a moderate temperature. Turn the knob toward the blue side to adjust for cold air, then press the AC switch. For warm air, turn it toward the red side. Related details are as follows: 1. Cooling Down: When the car's interior temperature remains high after being exposed to the sun, the correct cooling method is: first open the windows and doors for ventilation, wait for a while before starting the car, turn on the fan to disperse the hot air inside the air conditioning system, and then activate the AC for cooling. This ensures better cooling efficiency and fresher air. 2. Refrigerant: Some car owners add Freon refrigerant to their vehicles. During extremely hot summer days, excessive Freon refrigerant can cause high-pressure limits to be exceeded, leading to engine vibrations resembling thunder and sometimes even overheating. This is mainly due to the engine's relatively low power and aging components.
When I first got my BMW 3 Series, I wasn't sure how to operate the AC either, but later found it's actually super simple. First start the engine, then press the silver AUTO button on the center console - it automatically turns on the AC. Then rotate the round temperature knob: turn left to the blue zone for cooler air (I usually set it around 22°C). Don't worry about fan speed - the system adjusts automatically. However, when the car's extremely hot after summer sun exposure, I first open windows for 2 minutes ventilation before closing them and turning on AC, which cools faster. Pro tip: if AUTO mode's airflow feels weak, manually press the fan icon to increase speed. Another trick: long-press the AC menu to prioritize cooling seat backs - super helpful above 35°C. Remember to use recirculation mode for better cooling effect!
