What are the center console buttons in the BMW 7 Series?

ESP Button: ESP is the Electronic Stability Program, which effectively prevents loss of control such as body skidding or tail swinging. It is generally not recommended for drivers to manually turn it off. Auto Hold Button: When stopping at traffic lights or similar situations, after releasing the brake pedal, the Auto Hold function will lock the wheels, relieving the driver's foot fatigue. When the accelerator pedal is pressed, the wheels are unlocked, and the vehicle will proceed forward. Auto Start-Stop Button: After the function is activated, the engine will temporarily be in a shut-off state. When the brake pedal is released, the engine restarts to propel the vehicle forward. Internal/External Circulation Button: Internal circulation means the air inside the car is recirculated, while external circulation exchanges air between the inside and outside of the car. Internal circulation should be used in environments with heavy exhaust fumes, dust, or smog during traffic jams. On highways, it is advisable to periodically switch from internal to external circulation, with internal circulation preferably not exceeding one hour. Temperature Zone Sync Button: When the Temperature Zone Sync function is activated, 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, making it more user-friendly.
