What is the function of the ignition switch? In most cars, the ignition switch has four positions: OFF, LOCK, ACC, and ON. When the key is turned to the OFF position, the vehicle's electrical system is shut down and the engine is turned off. When the key is turned to the LOCK position, the steering wheel is locked and the car is secured. When the key is turned to the ACC position, the car's electrical system is powered on, but the engine remains off. The only time the engine can be started is when the key is turned to the ON position. In this position, the steering wheel can be unlocked and the car's basic functions can be used, including the radio and the headlights. It is important to note that the steering wheel cannot be moved too much when the car is locked. Additionally, the car's electrical system will remain on when the key is turned to the FF position.
