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 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.

Turning off the auto start-stop on the Vios is quite simple. Just locate the circular button with an arrow and the letter A near the gear lever. Press it lightly once, and the dashboard will display a shutdown prompt. The key point is that the engine must be running for the button to function—it won't work when the car is parked and turned off. I've found that the pressure applied when braking at a red light is crucial: light pressure won't trigger the start-stop, while heavier pressure activates it. This trick is more convenient than manually turning it off in city traffic jams. Although the feature is primarily designed for fuel savings, frequent starts do put a significant strain on the battery.

As a seasoned driver who frequently operates Japanese cars, the Vios' start-stop deactivation button is conveniently located on your right side. Simply press the button and you'll hear a crisp confirmation tone indicating it's turned off. Here's a lesser-known fact: when the AC is on with a significant difference between set and actual temperatures, the system automatically disables start-stop. For new cars in the break-in period, it's advisable not to rush turning it off as it may affect the manufacturer's fuel consumption data and subsequent . Additionally, always manually deactivate it before wading through heavy rain - if the engine stalls in water and auto-restarts, it could be completely ruined.

The actual test shows that the Vios auto start-stop has three levels of deactivation: First, manually pressing the physical button for a temporary deactivation, valid until the next ignition. Second, installing a deactivation device via the OBD interface for permanent deactivation, but this may affect the warranty. Third, skillful control—setting the air conditioning temperature at least 4 degrees lower or keeping the rear window defogger on will prevent the system from operating. Interestingly, activating this function requires meeting over a dozen conditions, including seatbelt fastening, door closure, engine temperature, etc. Understanding these can help you better manage it.

When I first got my Vios, I was most annoyed by the auto start-stop feature. But later I discovered Toyota's thoughtful design. The off button has clear tactile feedback - just press it and the yellow 'A' with a slash light on the dashboard will illuminate. After extensive use, I learned three things: First, turning it off during frequent short trips helps protect the . Second, keeping it on during long descents reduces brake pad wear. Third, be careful not to brake too hard when reversing, or the sudden engine shutoff during parking can be embarrassing. I recommend keeping the physical button and avoiding modifications, as you might need to temporarily enable it during annual inspections.
