How to Turn Off the Start-Stop Function in the 2019 Buick Excelle?
3 Answers
The method to turn off the start-stop function in the 2019 Buick Excelle is: there is an adjustment button for the automatic start-stop function on the center console. Before driving the car or during the driving process, pressing the adjustment button can turn off the start-stop function. Cars equipped with the automatic start-stop function have an additional electronic oil pump in the start-stop system's transmission. This is because when the engine is turned off, the main oil pump of the transmission cannot supply pressure, and the electronic oil pump supplies pressure to maintain the gear position. Taking the Buick Excelle 2021 Modified 1.3T Automatic Light Hybrid Base Model as an example, its length, width, and height are 4609mm, 1798mm, and 1486mm respectively, with a wheelbase of 2640mm, and the body structure is a 4-door 5-seater sedan. In terms of power, the Buick Excelle 2021 Modified 1.3T Automatic Light Hybrid Base Model is equipped with a 1.3L inline 3-cylinder turbocharged engine, with a maximum power of 120kW and a maximum torque of 230Nm, matched with a 6-speed automatic manual transmission.
I've been driving the 2019 Excelle for several years, and turning off the start-stop function has practically become my daily routine. After starting the car, there's a button with an 'A' icon on the left side of the dashboard near the steering wheel – just press it once to deactivate. You have to do this every time you start the car because the system defaults to 'on'. I feel this feature is a real nuisance in traffic jams when the engine keeps shutting off and restarting, making the car jerk around. It puts unnecessary strain on both the engine and battery while compromising driving comfort. After installing a dashcam myself, I noticed it drains the battery even faster. During routine maintenance, I always ask the mechanic to check the battery health. A word of advice: get regular check-ups to avoid premature battery failure due to excessive start-stop cycles, especially in cold weather. This design isn't very user-friendly – hopefully manufacturers can upgrade the system to include a permanent disable option.
As a car enthusiast, I've researched how to disable the start-stop system on the 2019 Excelle. After starting the vehicle, immediately locate the small button marked with the start-stop icon in the steering wheel button cluster - pressing it once will disable the system for the current driving cycle. In principle, automatic start-stop is designed for energy saving and environmental protection, but frequent starts/stops increase fuel system pressure and accelerate battery wear. I've seen user reports on community forums indicating generally shortened battery life. Therefore, I recommend paying extra attention to driving habits and conducting regular battery tests after disabling the system, especially since older vehicles are more prone to power drain. For a permanent solution, third-party modification parts might offer programmable permanent deactivation, but this carries risks - it's best to consult professional technicians. For safety, never operate the button while driving.
