How to Turn Off the Vios Start-Stop System?

Simply press the auto start-stop button. More related information is as follows: 1. The engine auto start-stop system automatically shuts off the engine when the vehicle comes to a temporary stop (e.g., at a red light) during driving. When it's time to move forward again, the system automatically restarts the engine. The STT intelligent fuel-saving system is a set of controls for engine start and stop. 2. The working principle of the start-stop system is that when the vehicle stops moving due to congestion or at an intersection, the driver presses the brake pedal and shifts to neutral. At this point, the Start/Stop system automatically checks: the engine is idling and not in gear; the wheel speed sensors of the anti-lock system show zero; the electronic battery sensor indicates sufficient energy for the next start. Once these three conditions are met, the engine automatically stops. When the traffic light turns green, the driver presses the clutch, and the 'start stopper' can be activated immediately, quickly restarting the engine. In automatic transmission models, as soon as the brake is released or the steering wheel is turned, the engine automatically ignites again, allowing the driver to press the accelerator and start moving immediately, all while remaining in D gear.
When I first drove the Vios, I kept thinking about how to turn off that auto start-stop function. It always shut off at red lights and gave a slight shake when restarting, which was really annoying. Actually, it's quite simple—just look for a small button with the letter "A" near the steering wheel. That's the switch; hold it for a few seconds to disable the start-stop for the current trip. If you want to permanently disable it, you'll need to go into the dashboard settings menu and uncheck the "Engine Start-Stop" option. I eventually turned it off because I felt the frequent starts and stops put too much pressure on the battery, especially in older cars, which could shorten the battery's lifespan. However, keep in mind that turning it off will slightly increase fuel consumption, but I prioritize a smoother drive. If you don't want to do it yourself, a quick visit to the 4S shop will get it sorted in minutes—they can also check if frequent starts are due to voltage issues.
