Which one is the recirculation mode in BMW 3 Series AM?
2 Answers
The 'M' on the BMW 3 Series indicates the recirculation mode. Below is an introduction to the meanings of recirculation and fresh air modes: 1. Recirculation mode: When using recirculation, the vehicle's interior acts like a sealed environment. Whether it's cold or warm air from the AC, it circulates within the car without allowing fresh air to enter. 2. Fresh air mode: When the fresh air mode is activated, external fresh air flows into the vehicle, improving the air quality inside. This is also a beneficial way to use the system. Below are extended guidelines on whether to use recirculation or fresh air mode during normal driving: 1. Summer: Use recirculation when cooling the car in summer to prevent external heat from entering, or during smog or traffic jams to avoid outside air. 2. Highway driving: Use fresh air mode during highway driving to ensure fresh air circulation, when smoking to quickly expel smoke, or after the car has been exposed to sun to release toxic gases inside the vehicle.
I've been driving a BMW 3 Series for several years and am quite familiar with the recirculation button. It's usually located on the center console's climate control panel, marked with an icon of a car interior and a circular arrow. Pressing it activates the recirculation mode when the indicator light turns on. This feature is particularly useful during traffic jams or hazy days, as it prevents external exhaust fumes and dust from entering the car. When using the automatic climate control, pressing the AUTO button adjusts the fan speed and temperature automatically, but the recirculation mode requires manual activation. Remember not to keep it on continuously during long drives, as it can make the air stuffy at high speeds - it's advisable to switch modes according to external conditions. While its exact position varies by model year, it's typically found on the left side of the button array below the screen, within easy reach. Occasionally cleaning the air filter helps maintain better air filtration performance.
