BMW air conditioning AM represents the car's internal and external air circulation modes. The 'A' stands for automatic switching between internal and external circulation, meaning the vehicle automatically detects and controls the air circulation. The 'M' stands for forced internal circulation, while external circulation is active when the light is off. During summer when using air conditioning, internal circulation can be employed. In heavy traffic during rush hours, especially in tunnels, internal circulation should be used as much as possible to prevent exhaust fumes or dust from entering. BMW is a German luxury car brand headquartered in Munich, Bavaria, Germany, owning three brands: BMW, MINI, and Rolls-Royce. The car's logo features a blue and white pattern, representing the coat of arms of Bavaria.

As a white-collar worker who frequently commutes in a BMW, I'm very familiar with the AM function of the air conditioning. It stands for Auto Mode, meaning you just set your desired temperature, such as 22 degrees, and the system automatically adjusts the fan speed and airflow direction. My daily commute takes an hour, and with AM, the temperature in the car remains consistently comfortable—gentle warm air in winter and quick cooling in summer. Manual operation requires constant adjustments, which can be distracting; last time I didn't use AM, I almost rear-ended another car. This design is very thoughtful—BMW engineers considered driving convenience, and it even saves a bit of fuel since the system intelligently avoids excessive airflow. Many might think AM is complicated, but the button is simple and easy to use. I highly recommend trying it—it can enhance your commuting happiness.

Should You Turn Off the Engine While Waiting at a Red Light?

If the red light wait time exceeds 2 minutes, you can turn off the engine; if the wait time is very short, you may choose not to. Here are some precautions regarding waiting at red lights: 1. Use Neutral Gear Plus Handbrake: When waiting at a traffic light intersection, using neutral gear plus handbrake minimizes vehicle damage in case of a rear-end collision. 2. Observe Both Sides: Long wait times at red lights can lead to hasty starts and neglect of observation, increasing the risk of accidents. Therefore, try to stay focused and observe both sides before starting. 3. Monitor the Rearview Mirror: During early morning or evening when traffic is relatively light, and especially on roads where large vehicles are common, continuously monitor the rearview mirror when stopped to ensure you can brake in time if needed.
