How to Use AOFF?

[VonAmelia]

AOFF usage is as follows: The auto start-stop function is enabled by default when the vehicle is powered on and ignited. It is suitable for situations when the car is driving in urban areas, encountering a red light, or during short stops. The auto start-stop function will activate, and the engine will automatically shut off after holding the brake for about two seconds. Working principle of the start-stop system: 1. When the vehicle stops 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 detects that the engine is idling without being in gear, the wheel speed sensors of the anti-lock system show zero, and the electronic battery sensor indicates sufficient energy for the next start. Once these three conditions are met, the engine automatically stops. 2. When the traffic light turns green, the driver presses the clutch, and the 'start stopper' can be activated immediately, quickly starting the engine. In automatic transmission models, simply releasing the brake or turning the steering wheel will cause the engine to automatically restart, allowing the driver to press the accelerator and start moving immediately, all while remaining in D gear.

Every time I get in the car and start the engine, I make it a habit to turn off the auto start-stop function. The button is located on the left side of the steering wheel. Pressing the button with a circled letter A, and when the yellow indicator light pops up on the dashboard, it means the system is turned off. Driving in the city and stopping at red lights, the start-stop system keeps shutting off and restarting the engine, which is really annoying. After turning it off, the car starts much more smoothly. However, I've tried keeping it on when driving on the highway, and it actually saves fuel, so it really depends on the road conditions. Remember, the system resets automatically every time you restart the engine, so you have to press the button again. This feature puts a lot of strain on the battery—I've had to replace my battery twice in three years, which is why I always turn it off now as soon as I get in the car.

Last time, the repair shop technician taught me about this button. A OFF is the switch that controls the engine auto start-stop function. You can find it in the center console area or on the side of the steering wheel—it's a button with the letter A surrounded by an arrow. After starting the vehicle, simply press it, and the corresponding icon will light up on the dashboard. I usually turn it off during traffic jams and when reversing, as frequent start-stop cycles can cause transmission shock. Once, during heavy rain while driving through a waterlogged section, a friend reminded me to disable this feature—otherwise, if the engine stalls, the system might automatically restart it, potentially leading to water ingress and engine failure. It's essential to develop a habit of checking the indicator light every time you start the car.

The operation is extremely simple: Locate the button on the center console marked with 'A OFF' or an 'A' inside a circle, press it once after starting the car. When the indicator light comes on, it means the auto start-stop function is deactivated. While this feature saves fuel, it can be harsh on the battery, so I usually keep it turned off. Note that the system defaults to 'on' after restarting the engine, requiring you to repeat the operation. It's crucial to disable it when driving through water to prevent the engine from restarting unexpectedly.

Here's how I use it: Every morning when starting the car, I casually press the A OFF button near the steering wheel with my left hand. When the yellow warning light appears on the dashboard, the auto start-stop function is deactivated. Modern cars have memory functions, so it will reactivate next time you drive. There are three main situations when it must be turned off: frequent start-stops during traffic jams are annoying, it can accidentally trigger engine shutdown during parking maneuvers, and it's particularly dangerous when driving through water during rain. Last week during car washing, I noticed the battery terminals had oxidized - the mechanic said it was caused by the auto start-stop system. It's more worry-free to keep it completely turned off.

That time when I was driving in the mountains, I suddenly realized the importance of A OFF. It's particularly dangerous when the auto start-stop engages during continuous downhill engine braking. Since then, I've developed a habit: right after starting the car, I check the center console and press the button with a circle and an A. Only when the yellow warning light appears on the dashboard do I consider it successfully deactivated. Turning it off at city traffic lights prevents vibrations, deactivating it before wading protects the engine, and turning it off in summer avoids air conditioning interruptions. However, the system resets after each engine shutdown, and long-term non-use can lead to premature battery failure. My experience is to keep it off unless I'm going on a long trip.
