What position does ACC refer to in a car?
2 Answers
ACC is the ignition switch position. Here is the relevant information: 1. If the key has an ACC position, simply turning the key to this position will power on some devices. When starting the car, a strong current is required, at which point ACC will stop supplying power. Once the car is started, it resumes power supply. 2. ACC power is a car power source controlled by the car key, supplying power to components such as the car audio system. Generally, car keys have 4 positions: OFF, ACC, ON, and the start position. However, some models only have 3 positions, meaning they lack the ACC position.
ACC refers to a position on the car's ignition switch, and its full name is the Accessory position. When you turn the key or press the button to this position, the engine does not start, but the car can supply power to accessories such as the radio, cigarette lighter, or phone charging port. I always switch to ACC when waiting for friends by the roadside, listening to some music to pass the time while saving fuel. However, the ACC position only supports low-power devices, so the air conditioning or headlights may not work. Prolonged use of ACC can drain the battery—I once forgot to turn it off in a park, and the battery died, nearly requiring a tow truck. So, for safety, keep usage short, preferably under 30 minutes. New drivers should practice and familiarize themselves with the positions to avoid confusion with the ON position for starting. The benefits of ACC include quiet operation, energy savings, engine protection by reducing idle waste, and eco-friendly design, which is commendable.
