Functions of the buttons inside the Buick GL8?

[DelCaden]

1. Electronic Stability Program (ESP): Effectively prevents body sideslip, 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 functions, providing drivers with alarms and visual feedback to detect surrounding obstacles. 3. Auto Hold: Eliminates the need to keep the foot on the brake pedal continuously, as the system automatically locks the wheels. The wheels unlock when the accelerator pedal is pressed, allowing the vehicle to move forward immediately. 4. Auto Start-Stop: The engine shuts off during brief stops. The vehicle restarts when the driver's foot leaves the brake pedal. 5. Internal/External Air Circulation: Internal circulation means the air inside the vehicle is recirculated, while external circulation allows air exchange between the inside and outside of the vehicle. During traffic jams, in tunnels, or when external air quality is substandard, internal circulation should be prioritized. On highways, switch to external circulation periodically to refresh the air and prevent health issues caused by stale air.
