Accessory mode in a car allows you to use certain electrical components without fully turning on the engine. It is useful when you want to listen to the radio, charge your phone, or operate the power windows while the engine remains off. Usually, turning the key to the first position before starting the car activates this mode. However, you can achieve this without the key through alternative methods.
