How to Turn Off the Auto Start-Stop Function on the Buick Envision
2 Answers
The auto start-stop button for the Buick Envision is located on the right side of the center console screen. When the light is on, the auto start-stop function is enabled; pressing the button to turn off the light will disable the auto start-stop function. Additional information about the Buick Envision is as follows: 1. How the Buick Envision's engine start-stop system works: When the vehicle stops moving due to traffic congestion or at an intersection, the driver presses the brake pedal and shifts into neutral. At this point, the Start/Stop system automatically checks: the engine is idling and not in gear; the system's wheel speed sensor shows zero; the electronic battery sensor indicates sufficient energy for the next start. Once these three conditions are met, the engine automatically stops. When the driver shifts into gear and presses the accelerator, the engine restarts and continues to operate. 2. Car idling: The auto start-stop technology is primarily used in traffic congestion situations, where the engine is usually warm, and the fuel consumption of a warm engine starting is minimal. The engine can typically start at 350 rpm, which is nearly half the idle speed. Assuming there are no other loads besides the engine's internal resistance during the start-up process and the necessary equipment such as the transmission's loss, the fuel consumption is certainly less than during idle conditions.
I've been driving the Buick Envision for a few years, and the auto start-stop feature can be quite annoying at city traffic lights, with the engine constantly starting and stopping affecting the driving experience. Turning it off is simple—just look for the button with an "A" letter near the steering wheel or on the dashboard (sometimes labeled "Auto Stop"), press it, and the light will turn on, indicating it's deactivated. After each car start, it might reset automatically, so you'll need to press it again manually. I usually recommend checking the user manual in case of model differences, as some newer models might require adjustments through the touchscreen settings. Don't worry about fuel efficiency after turning it off—the engine starts more smoothly, especially in traffic jams, preventing constant jerking and making driving more comfortable.
