Should the AOFF in an automatic transmission be kept on or off?

[VonAdriana]

Automatic transmission AOFF is generally kept on. AOFF is the button to turn off the auto start-stop function in a car. Enabling the auto start-stop function can reduce exhaust emissions and save fuel, which is why many cars are now equipped with it. Here are detailed explanations about the auto start-stop function: 1. Cars equipped with the auto start-stop function have a button to turn it off. Pressing this button can deactivate the auto start-stop. The button to turn off the auto start-stop is not actually labeled as 'aoff', but rather features a circle with an 'A' inside and 'OFF' below the circle, indicating the deactivation of the auto start-stop. 2. In cars with the auto start-stop function, when waiting at a red light, the system will shut off the engine as long as the battery has sufficient charge and the engine coolant has reached the normal operating temperature. If the battery charge is insufficient, the auto start-stop system will not function.

I usually keep the A OFF function (auto start-stop) enabled in my automatic transmission car. Using the auto start-stop system in the city is very convenient - the engine automatically shuts off at red lights, saving me quite a bit on fuel costs. I save dozens of dollars on gas every month. Especially in traffic jams, frequent engine shutdowns during stops reduce idle consumption, making it both eco-friendly and economical. Modern cars restart the engine very smoothly with minimal vibration - you get used to it after driving for a while and it doesn't cause any discomfort. The only thing to note is that when running AC on hot days, engine shutdown might affect the cooling, but I solve this by using air recirculation. Overall, keeping it on not only saves money but also reduces emissions - it's my top choice for urban driving. I only manually turn it off in special situations, like when frequently changing lanes.

I usually keep the A OFF button for the automatic start-stop system turned off. Having it on always makes me feel the car jerks a bit, which is uncomfortable. Although the vibration when restarting the engine is slight, it disrupts the driving experience and is even more annoying in traffic jams. Saving fuel is a small gain for a big hassle, as keeping it on increases wear on the starter and battery, leading to higher maintenance costs in the long run. When driving on highways or in suburban areas, I often keep it off, feeling more at ease with the engine running smoothly. Occasionally, I might try turning it on for short city trips, but overall, I prioritize comfort and prefer keeping it off. In cold weather, with the heater on, keeping the engine running ensures quick warming and avoids delays from restarts. Turning it off is worry-free and effortless, prioritizing driving comfort.

Keeping Auto Start-Stop ON is beneficial. It saves fuel, reducing fuel consumption by approximately 5% in city driving. It's especially useful during frequent stops, minimizing idle emissions. The engine restart is designed to be smooth, with negligible vibrations. Turning it OFF may offer a quieter experience but wastes resources. Keeping it ON strikes a balance between practicality and environmental friendliness.

I switch the A OFF function of the automatic transmission according to the situation. When driving in the city, I often keep it on for fuel efficiency and environmental friendliness, especially with frequent red lights to save some money. On highways or smooth roads, it's better to turn it off, as frequent start-stop doesn't have much effect and may even increase vibrations. In bad weather, such as heavy rain, keeping it on might cause the system to restart too frequently, affecting stability, so turning it off directly is safer. Driving habits also matter—keeping it on is fine for long stops, but for short stops, it's better to turn it off to avoid annoyance. Overall, flexible use can save costs when turned on, while turning it off enhances comfort without any issues.

I prefer to keep the Auto Start-Stop (A OFF) turned off. While it saves fuel when activated, the frequent engine restarts are uncomfortable, and the vibration during each restart disrupts the driving rhythm. It's especially annoying in heavy traffic, but with it turned off, the car feels much smoother and quieter. In the long run, keeping it on may wear out the starter motor prematurely—a friend's car had an early failure due to this. A continuously running engine is more reliable, especially when using the AC, as turning it off maintains cabin temperature faster. Occasionally, I try activating it for environmental benefits, but personally, I prioritize comfort and peace of mind by keeping it off.
