How to Turn Off the Auto Start-Stop Feature in Vios?

To turn off the auto start-stop feature in Vios, simply press the auto start-stop button. Generally, the dashboard will indicate that the system is turned off. If you wish to use this function again, press the button to turn it back on. Vehicles equipped with auto start-stop usually have this feature enabled by default. Below is some information about the start-stop system: 1. Engine auto start-stop automatically shuts off the engine when the vehicle comes to a temporary stop (e.g., at a red light) and restarts it when it's time to move again. The system is officially called STOP&START, abbreviated as STT. The STT intelligent fuel-saving system controls the engine's start and stop functions. 2. The start-stop system works by detecting when the vehicle stops due to traffic or at an intersection. The driver presses the brake pedal and shifts to neutral. The Start/Stop system then checks three conditions: the engine is idling and in neutral; the wheel speed sensors of the anti-lock system show zero; and the electronic battery sensor indicates sufficient energy for the next start. 3. Once these conditions are met, the engine automatically stops. When the traffic light turns green, the driver presses the clutch, activating the 'start stopper' to quickly restart the engine. 4. In automatic transmission models, releasing the brake or turning the steering wheel will immediately restart the engine, allowing the driver to accelerate without shifting from D gear.
Last time I drove my friend's Vios, I also checked this out. The auto start-stop button is located near the gear lever on the center console, usually marked with an 'A' inside a circle. Just press the button once, and a yellow 'Auto Start-Stop Off' indicator will appear on the dashboard to confirm it's deactivated. However, it resets to the default 'on' state every time you restart the car, so you need to get into the habit of pressing it after ignition. My friend said he particularly dislikes the feeling of the engine shutting off at red lights, especially in summer when the frequent restarts cause noticeable vibrations with the AC running. For those who want to disable it long-term, some owners install an auto start-stop deactivation module, but it's not recommended to tamper with the original wiring.
