How to Turn on the Air Conditioning in a BMW 3 Series?

[StJade]

BMW 3 Series comes standard with automatic air conditioning, and the control buttons are located on the center console panel. Press the temperature adjustment button on the right side of AUTO and set the temperature to a comfortable level. The temperature for the car's cooling system should not be set below 25 degrees Celsius, and the temperature difference between the inside and outside of the car should not be too large, preferably not exceeding 5 to 6 degrees Celsius. Precautions for using car air conditioning: 1. Turn off the air conditioning a few minutes before reaching the destination: Turn on the natural wind to allow the temperature in the air conditioning ducts to rise, maintaining relative dryness in the air conditioning system and preventing mold growth. 2. When turning on the cooling, point the air vents upward: When turning on the heating, point them downward. This is due to the physical principle that hot air rises and cold air sinks. 3. Do not set the air conditioning to recirculation mode: This will make the air in the cabin stale and gradually reduce the oxygen content inside the car. When the oxygen level is too low and the air is stale, people often experience dizziness, which is very dangerous when driving in this state. 4. Do not use the air conditioning when the car is driving at low speeds: If you encounter traffic congestion while driving at low speeds with the air conditioning on, the engine's rotation frequency will be higher, and prolonged high-speed operation can easily damage the engine. Once the engine's lifespan is shortened, the car's service life will also be reduced accordingly.
