What does the BMW AOFF button mean?
2 Answers
The "AOFF" button in the car is the auto start-stop switch, used to control the engine's auto start-stop function. Here is an introduction to the use of the AOFF button: 1. Auto start function: After getting in the car, the auto start-stop function is enabled by default, and the AOFF button is in an off state. 2. Simply press the brake pedal: While driving, simply press the brake pedal, and the engine will automatically shut off after the vehicle comes to a complete stop for about two seconds. Keeping the brake pedal pressed will maintain the engine in a closed state. 3. Release the brake or turn the steering wheel: As soon as the brake is released or the steering wheel is turned, the engine will automatically restart immediately, and the car can be driven by pressing the accelerator pedal directly.
That A OFF button, as someone who's driven BMWs for years, is actually for turning off the auto start-stop function. Auto start-stop means the engine shuts off automatically when stopping to save fuel, but in daily traffic with frequent stops and starts, the car keeps shaking, which is quite uncomfortable. Press this button to turn it off, and the ride immediately becomes much smoother. It's usually located near the steering wheel or on the center console with an A plus OFF symbol—just a simple press to operate. I've found that keeping it on during highways or long distances can save some fuel, but turning it off in city traffic is more comfortable. After restarting the car, the system often defaults to on, requiring manual deactivation each time, which actually reduces strain on the battery. Using this button wisely can enhance the driving experience—recommend deciding whether to turn it off based on road conditions.
