How to Turn Off the Auto Start-Stop Function in the Buick Excelle?

[LeilaAnn]

To turn off the auto start-stop function in the Buick Excelle, press the adjustment button either before driving or during the driving process. The auto start-stop system automatically shuts off the engine when the vehicle comes to a temporary stop, such as at a traffic light, and restarts it when it's time to move forward again. Taking the 2021 Buick Excelle as an example, it features a four-door, five-seater sedan body structure with dimensions of 4609mm in length, 1798mm in width, and 1464mm in height, a wheelbase of 2640mm, a fuel tank capacity of 44 liters, and a curb weight of 1270kg.

I've been driving a Buick Excelle for three years, and the auto start-stop feature can be quite annoying. The way to turn it off is simple: after starting the car, find a button near the air conditioning panel marked with an 'A' inside a circle, press it to light up the indicator. However, it resets every time you restart the vehicle, so make it a habit to turn it off as soon as you get in. It's advisable to turn it off during traffic jams, as frequent start-stops can shorten the battery's lifespan, especially when the AC is on—this is the most damaging. I later installed an auto start-stop deactivator, though the original design's repetition is meant to save fuel. City driving fuel consumption shows a reduction of about 0.5L, but the battery drain is significant—I've replaced two in three years.

The auto start-stop button on the Buick Excelle is quite easy to find - it's the 'A' button with an arrow symbol next to the gear shift on the center console. After starting the car, press it once and the dashboard will display the start-stop deactivation icon. However, the design is somewhat flawed as you need to press it again every time the engine restarts. Last week, I noticed the start-stop malfunction indicator stayed lit constantly, and later found out the frequent cycling had damaged the battery sensor. Now with AC running in hot weather, the system rarely activates, but the mandatory engine shutdown at every winter stop is truly annoying. Actually, the start-stop system monitors battery charge (disabling automatically below 70%), AC pressure and brake pressure. Most owners keep it permanently off though, especially since replacing an AGM battery costs about 1,500 yuan.

I've specifically researched the auto start-stop function. There's a button with an 'A' on the lower left side of the Encore's steering wheel – just press it immediately after starting the car. This feature monitors 32 parameters; for instance, it won't activate if the coolant temperature is insufficient. The real-world experience isn't great, especially in winter when the engine shuts off before properly warming up, causing noticeable vibrations. A dealership technician once mentioned frequent start-stop cycling could reduce the starter motor's lifespan by 30%, so I usually keep it disabled. Newer models with 48V mild hybrid systems might perform better. I'd advise against ECU modifications to disable it, as that could void the warranty. Also, the stop duration lasts longer with a fully charged battery, though running the AC may trigger a restart within 15 seconds.

The most annoying thing about commuting in the Excelle is the auto start-stop. The off button is right in front of the gear lever, a cylindrical button with the start-stop icon. Press it and the indicator turns yellow to show it's off, but you have to turn it off again after restarting the engine. I found that the start-stop system is automatically disabled when the front defroster is on because the compressor needs the engine to run. Owners in the north should turn it off even more, as start-stop in winter prevents the water temperature from rising. Actually, the auto start-stop only activates below 22 km/h and the engine shuts off when you brake hard at a red light. Some owners buy start-stop deactivation harnesses on Taobao, but modifying the wiring might void the insurance. It's better to just get used to pressing the button—it's an easy habit to form.
