How to Use the BMW X1 Central Control Screen?

BMW X1's central control is the area for managing the car's air conditioning, audio, and other comfort and entertainment devices. Detailed instructions are as follows: 1. Electronic Stability Program (ESP): Effectively prevents body skidding, fishtailing, and other loss-of-control situations. It is generally not recommended for drivers to manually turn it off. 2. Parking Radar/Image: This button activates the panoramic image and radar function, providing audible alerts and visual feedback to help the driver detect surrounding obstacles. 3. Internal/External Air Circulation: Internal circulation means the air inside the car is sealed and recirculated, while external circulation allows air exchange between the inside and outside of the car. Use internal circulation first when in traffic jams, tunnels, or when the outside air quality does not meet standards. On highways, switch to external circulation periodically to ensure fresh air and prevent health issues. 4. Temperature Zone Sync: When the temperature zone sync function is enabled, changing the driver's seat temperature will cause the other zones to follow. Additionally, when this function is turned off, each zone can be adjusted individually for a more personalized experience. 5. Auto Start-Stop: The engine will shut off during brief stops. When the driver's foot leaves the brake pedal, the vehicle will restart. 6. Auto Hold: Eliminates the need to keep the foot on the brake, as the system automatically locks the wheels. The wheels unlock when the accelerator pedal is pressed, allowing the vehicle to move forward.
