What is the mysterious ACC mode on the car ignition lock.

One of the useful, but possibly not so obvious functions in your car is ACC mode, or accessory mode. It allows you to use certain systems without starting the engine.

This was written by Slash Gear.

How to activate ACC

In modern cars with push-start, activating ACC is simple - just press the 'Start/Stop' button without pressing the gas pedal. In older models, you can do this by turning the key to the appropriate position.

ACC allows you to use battery power to power some systems while the engine remains off.

This is useful if you need to keep the car on but don't want to waste fuel.

Most gasoline cars have this mode. Regarding electric vehicles, there is no standard for auxiliary mode for them, but some models offer this feature, including the Kia EV6.

What can be used

ACC is limited to certain functions, including electric windows, audio system, wipers, charging gadgets, navigation system. Windows, music, and ACC will make your waiting time more pleasant and economical compared to idling the engine.

Impact on the battery

The downside of ACC is the potential draining of the battery. However, it does not happen instantly, so use ACC safely for several hours to avoid the risk of draining the battery.

The overall conclusion from this news is that the accessory mode in the car allows you to use certain systems without turning on the engine, allowing you to save fuel and reduce the negative impact on the environment, especially in situations where the driver is forced to wait in the car for an extended period.
