What does ignition on mean?

ignition on means to start the engine. If the vehicle is already powered on, it may indicate that the engine can be started. Car starting method: When starting the car, turn the key to the LOCK position. Sometimes it cannot be turned, and you need to shake the steering wheel slightly. This is because the steering wheel is locked in this position. Be careful not to use excessive force to turn the key, as it may cause damage. When the key is turned to ACC, the main circuit of the car is powered on, ensuring the normal power supply of the car's circuits. The onboard computer will check if the data is normal, and you should wait for three to five seconds at this stage. When the key is turned from ACC to ON, you will hear the sound of the fuel pump drawing fuel, as the car prepares for normal driving. The dashboard lights will automatically display whether everything is normal, and the key should generally remain in this position for seven to eight seconds. When the key is turned from ON to START, release it after hearing the engine start, and the key will automatically return to the ON position. Do not manually return it to ON to avoid engine damage. Car starting precautions: Pay attention to the time interval when turning the key from LOCK to START. Ignoring this may cause errors in the onboard computer's self-check. Also, ensure the key is not left in the START position while driving, as this may cause the starter to continue working and lead to circuit malfunctions.
Hey, as someone who studies cars all day, let me explain what 'ignition on' means. It's when the ignition switch is turned on, meaning you're ready to start the engine or the car's systems are already activated. When you turn the key or press the start button, the position is usually at 'on,' and current flows to the ignition coil and spark plugs, igniting the fuel in the engine to get the car moving. This is super important because without this step, the engine would be dead and unable to start. I've encountered this many times—ignition on but the car doesn't start, which could be due to a weak battery, a faulty starter motor, or key sensor issues. I recommend checking once before daily driving by turning to 'on' and listening for sounds. Don’t forget regular maintenance, checking battery voltage and connections to avoid the embarrassment of breaking down midway. Modern cars with push-button start are more convenient, reducing the risk of wear and tear from old-fashioned keys.
I drive to work every day, and 'ignition on' refers to the starting phase of driving. For example, when I'm in a hurry in the morning, I get into the car, turn the key to the position where the dashboard lights up, and the system is warming up but the engine hasn't started yet. At this point, the car is silent. If left on for too long without starting, the battery will gradually drain. I once forgot to turn it off while parked, and the next day the car wouldn't start. Simply put, it's a transitional state, a preparatory step from off to fully starting. Beginners might misunderstand and think that turning it on means the engine is running, but in reality, you still need to press the brake and push the start button for it to operate. After driving, it's recommended to develop good habits: turn it off before getting out of the car and use a portable charger to prevent battery aging.
