How to Use the Engine Start-Stop Function in the Excelle?
5 Answers
The usage method of the Excelle's engine start-stop system is as follows: The system is enabled by default after the engine starts. The switch is located next to the ignition switch or on the center console. Pressing the button can manually deactivate the automatic start-stop system. When the start-stop function is enabled, with the gear lever in D position and the brake pedal depressed, the system stops when the tachometer needle points to the AUTOSTOP position. The Excelle is a compact car under SAIC-GM, equipped with a 1.3T or 1.0T Ecotec dual-injection turbocharged engine. The Super Connected Edition model features Buick eConnect connectivity technology, a human-machine interface, and supports cloud-based connected applications and services.
Using the engine start-stop function on the Buick Excelle is quite simple. After starting the car, the system is usually enabled by default, and an indicator light or an "A" symbol will appear on the dashboard. When you come to a complete stop at a red light or in traffic, the engine will automatically shut off to save fuel. As soon as the light turns green or you lightly press the accelerator, it restarts immediately and continues driving. At first, I felt a slight shudder during the restart, but after a few drives, I got used to it—it really does save fuel. Just remember, the battery needs to be in good condition; otherwise, the system might not work. In cold weather or when the AC is on high, it may also pause automatically to protect the battery. It’s great for daily commutes—fuel-efficient and eco-friendly. I recommend trying it and getting familiar with the rhythm.
After starting the LaCrosse, the start-stop function automatically goes into standby mode, indicated by a small icon on the dashboard. When you come to a complete stop and firmly press the brake, the engine shuts off to save fuel. Release the brake or press the accelerator when the light turns green, and the engine restarts immediately. The fuel-saving effect is noticeable, and as someone who has driven for many years, I find it very practical. Note that it may not function if the weather is too cold or the battery is low, to prevent any mishaps. Occasionally, there might be a slight vibration during restart, but it doesn’t affect driving comfort. Avoid stomping on the brake or accelerator while driving, as it can disrupt the start-stop rhythm. New drivers may need some time to get used to it.
The automatic start-stop operation of the Excelle is ready once the car is started. The engine shuts off when stopping at a red light by pressing the brake, and restarts when releasing the brake at a green light. It's fuel-efficient and convenient, making daily driving effortless. I always check the dashboard lights to confirm the status. The system may pause operation if the temperature is too high or too low. The restart vibration is slight and easy to get used to quickly. Maintaining the battery well ensures the function works properly.
The start-stop function logic in the Excelle is intuitive. It activates by default upon starting the car, with status displayed on the dashboard. When stopping steadily with the brake pressed, the engine automatically shuts off to save fuel; releasing the brake prompts a quick engine restart. I've studied the system principles—it only engages when battery voltage is sufficient and engine temperature is normal, automatically disabling during high-power AC usage for protection. The restart process has a slight delay but is smooth, saving about 10% fuel. Drivers should maintain steady brake pressure for optimal operation.
