How to Turn Off the Auto Start-Stop Feature in the Excelle?
2 Answers
The start-stop function switch in the Excelle is located next to the ignition switch or on the center console panel. After the engine starts, the auto start-stop system becomes active. You can manually deactivate the auto start-stop system by pressing the button. Below is some relevant information about the Excelle: 1. Interior: The new Excelle cockpit continues Buick's 360-degree wraparound integrated design, complemented by high-touch interior materials and Quiet-Tuning, Buick's patented noise reduction technology. It features a three-spoke multifunction steering wheel, ice-blue sporty instrument panel, fully automatic air conditioning system, one-button start function, rear air conditioning vents, and a flexible 400L luggage compartment. 2. Powertrain: The new Buick Excelle offers two powertrain combinations: a 1.3T dual injection turbocharged engine paired with a 6-speed DSS intelligent dual-clutch transmission, and a 1.0T dual injection turbocharged engine paired with a 6-speed DCG intelligent dual-clutch transmission. The former delivers a maximum power of 120kW at 5500 RPM and a peak torque of 230N.m between 1800~4400 RPM, while the latter provides a maximum power of 92kW at 5600 RPM and a peak torque of 170N·m between 1700-4400 RPM.
When driving the Excelle, the auto start-stop function keeps shutting off the engine at every stop in the city, and the noticeable shake during restart is quite annoying. Turning it off is simple. Just press a small button near the steering wheel marked with an 'A' or the start-stop OFF symbol – the illuminated light indicates the function is disabled. In most models, this button is located on the left side of the instrument panel. If you can't find it, refer to the owner's manual for diagrams. You'll need to disable it each time you start the car since the system defaults to ON. Deactivating it results in smoother driving with less noise. If the button doesn’t respond or the light fails to activate, it might indicate low battery charge or a sensor issue—check the battery voltage to avoid affecting the system’s automatic reactivation. Frequent use of start-stop during short trips increases engine wear, so periodically disabling it benefits the vehicle. Personally, I recommend turning it off in cold winter conditions for safer driving and better comfort.
