What does Volkswagen's AOFF mean?

[DiBrantley]

Volkswagen's AOFF is the button to turn off the automatic start-stop function. How the automatic start-stop function works: By installing an enhanced motor with idle start-stop function on a traditional engine, the engine is completely shut off when the car meets the conditions for idle parking. When the vehicle needs to start moving again, the idle start-stop motor system quickly responds to the driver's start command and rapidly starts the engine, achieving instantaneous connection, thereby greatly reducing fuel consumption and exhaust emissions. The role of the automatic start-stop function: It can reduce exhaust emissions and save fuel. For cars equipped with the automatic start-stop function, when waiting at a traffic light, as long as the battery has sufficient charge and the engine coolant reaches the normal temperature, the system will shut off the engine. If the battery charge is insufficient, the automatic start-stop system will not work.
