1 Answers
Here is the relevant introduction to the functions of the buttons in the BMW 5 Series: 1. Internal and External Circulation: Internal circulation refers to heating or cooling the air inside the car and then sending it back into the car, while external circulation allows outside air to enter the car. Generally, internal circulation is turned on in congested areas or when the outside air quality is poor. On highways, it is advisable to switch to external circulation every hour or so to replace the air inside and outside the car to prevent oxygen deprivation. 2. Temperature Zone Synchronization: After enabling the temperature zone synchronization function, changing the temperature in the driver's seat will synchronize the changes in the other temperature zones. Additionally, when this function is turned off, each zone can be adjusted individually for temperature, making it more user-friendly.
