How to turn off the engine start-stop in the 14th generation Sylphy?

14th generation Sylphy automatic start-stop deactivation method is as follows: 1. Directly press the automatic start-stop button (a circular arrow containing the letter A), and the dashboard will indicate system deactivation. 2. If you want to use this function again, simply press the button to reactivate it. 3. After activating automatic start-stop, applying slight pressure to the brake pedal will cause the engine to shut off; pressing the brake again will restart the engine, thereby achieving fuel savings. Below are the drawbacks of automatic start-stop: 1. Higher maintenance costs for the battery and starter: Frequent engine starts and stops can cause damage to related components such as the starter and battery. Although vehicles equipped with automatic start-stop systems use enhanced starters and batteries, in practice, their failure rates are higher than those of ordinary vehicles without this system. 2. Poor user experience: The design of automatic start-stop systems varies across different models and brands. Some models have suboptimal start-stop logic, with inaccurate timing for system intervention, and sometimes the system fails to activate during prolonged stops. 3. Increased fuel consumption in traffic jams: In severe traffic congestion, if the engine remains off for an extended period, the combustion chamber temperature drops, leading to the formation of carbon deposits from unburned hydrocarbons and paraffin on the cylinder walls. Poor fuel quality exacerbates this issue. Carbon deposits can increase fuel consumption and reduce engine power, counteracting the fuel-saving purpose of the automatic start-stop function and instead raising fuel consumption.
I've always found the auto start-stop function quite annoying for city driving. When I first got my Nissan Sylphy, I looked into how to disable it. The engine auto start-stop is enabled by default, and there's a circular button with an 'A' and an arrow symbol near the center console, usually located below the AC controls or next to the gear shift. Pressing it will display an auto start-stop deactivated icon on the instrument cluster - the yellow light indicates it's turned off. The annoying part is that it automatically reactivates every time you start the car, so pressing this button becomes the first thing to do after ignition. Get used to this routine - it takes just two seconds if you're quick. Some people ask whether disabling it affects fuel economy. Honestly, for short commutes the difference is negligible, while eliminating the jerky sensation from repeated engine restarts. Of course, keep it enabled for highway driving - that's where the real fuel savings happen. Remember to check your glove compartment manual for the exact button position as it might vary slightly across model years.
