What are the functions of the center console buttons in the 2011 Buick Excelle?

[Kendall]

2021 Buick Excelle center console button functions are explained as follows: 1. Electronic Stability Control (ESC): The system is enabled by default. It is not recommended to turn it off except on slippery roads such as during rain or snow. 2. Auto Start-Stop: Briefly turns off the engine at traffic lights. The vehicle will restart when the driver's foot leaves the brake pedal. 3. Recirculation/Fresh Air Mode: Recirculation heats or cools the air inside the vehicle and recirculates it, while fresh air mode allows outside air to enter the vehicle. Use recirculation mode in heavy traffic, tunnels, or when outside air quality is poor. On highways, switch periodically from recirculation to fresh air mode, and avoid using recirculation mode for more than one hour at a time.
