Can the A button in the car be kept on for a long time?

It can be kept on for a long time. The A button in the car is the auto-hold function. After activating the auto-hold function, it can avoid frequent operation of the handbrake or electronic handbrake. Related introduction of auto-hold: Vehicles with electronic handbrakes are generally equipped with the auto-hold function. This function is not enabled by default and needs to be manually activated by the driver. After activating the auto-hold function, it can avoid frequent operation of the handbrake or electronic handbrake, and automatic transmission models do not need to frequently switch between D to N and D to P. When the vehicle is braked to a stop during driving, even if the brake pedal is released, the vehicle may not continue to move. Only when the accelerator pedal is pressed again will the vehicle continue to move forward. The English name of auto-hold is AUTOHOLD, and this button is mostly placed next to the electronic handbrake. The role of auto-hold: When encountering a short stop at a traffic light, the system will automatically brake the wheels after the vehicle stops to prevent rolling; When starting on an uphill slope, the system will automatically brake to prevent rolling back. After starting, the system will automatically release the wheels and move forward directly; When parking and locking, there is no need to pull the handbrake. The system will automatically brake the wheels at this time, but this is only seen in some models.

I often turn off that A button while driving, the one with the A symbol near the dashboard, which controls the auto start-stop function. It's perfectly fine to keep it turned off long-term, as the car was designed with user preferences in mind. When I'm at a red light with it turned off, the engine doesn't automatically shut down, reducing vibrations and making the ride more comfortable. However, keeping it off all the time may consume a bit more fuel and could lead to faster wear on the battery or starter. I recommend keeping it on during traffic jams to save fuel and turning it off on highways. Having driven for three to four years, I've gotten used to adjusting it based on road conditions. During each maintenance check, I ask the technician to ensure the system is working properly.

I've tried keeping the auto start-stop function (the A button) turned off for extended periods. On most vehicles, you can hold the button until the indicator light comes on to keep it disabled, though it resets to default ON position with each engine restart. This operation won't harm your car - engineers specifically designed it knowing drivers might dislike the start-stop vibration. Just be aware prolonged deactivation may slightly increase fuel consumption (especially in urban traffic) and accelerate battery aging. Regularly check your vehicle's electrical system to ensure proper functioning. Personally, I find it quite convenient to disable during long highway drives for smoother operation.

The A button can be left turned off, as it controls the engine start-stop function. Every time I turn it off when driving, I feel the acceleration becomes smoother, and the engine won't suddenly shut off at traffic lights. There's no problem keeping it off long-term, and the car won't malfunction. The manual states users can adjust it anytime. However, keeping it on does help save some fuel costs, especially in urban areas with many traffic lights. I usually keep it on in the city and turn it off on highways. Remember to mention this during maintenance, as the technician will check the battery condition.

I always keep the A button, which is the engine start-stop button, turned off in my car. At first, I wasn't sure if it could be left off permanently, but later I asked the mechanics, and they said this button is used to manually switch the system. Turning it off doesn't affect the car's performance, and it still runs normally. The advantage is that the car becomes quieter without the vibrations from the start-stop function. The downside might be a slight increase in fuel consumption, and if the battery is old, it might drain more easily. They suggested trying to turn it on occasionally in heavy traffic and switching based on the situation. I've been driving like this for over two years without any issues, just making sure to go for regular check-ups and maintenance.

I always keep the A button turned off, as it controls the auto start-stop function. It's safe to leave it off for extended periods. With it off, the engine doesn't shut down when stopping, making the drive feel smoother. Although it may slightly increase fuel consumption, the impact is minimal under good road conditions. The car's design allows users to decide the on/off state, so there's no need to worry about component damage. Just be aware that keeping it on in frequent start-stop traffic may save more fuel. Personally, I habitually turn it off and only activate it during heavy traffic to balance convenience and fuel efficiency. Just ensure the battery health is checked during each maintenance to keep everything in good condition.
