What does temporarily parking and turning off the ignition switch mean?

Turning off the ignition switch means turning the key all the way to the end. Introduction to car key positions: The keyhole generally has 4 positions. When the key is inserted, it is in the LOCK position. Turning the key to ACC: powers on some of the vehicle's electrical components, such as the CD player and cigarette lighter. Turning the key to ON: powers on all electrical components in the vehicle and initiates a self-check. The ignition position is where the key returns to the ON position after successful ignition. Precautions for using car keys: After starting the car, immediately release the key. Keeping it turned can damage the engine belt. Do not hang the key together with accessories, as collisions with accessories can gradually widen the keyhole gap. Avoid exposing the key to high temperatures or contact with liquids.

When I was learning to drive, the instructor always emphasized this: temporarily turning off the ignition means turning the key to the ACC position. For example, when waiting by the roadside for more than three minutes, I do this—the engine stops, but the radio still works. The driving school instructor said this protects the starter and saves fuel. It's most commonly used when picking up parcels at courier stations—everyone in our line of work knows that short-term engine shutdown can save a lot on fuel costs. Remember, never do this in D gear; for automatic transmissions, shift to P gear first before turning the key.

Last time when getting my car repaired, the mechanic taught me: turning off the ignition switch for short stops means keeping the vehicle powered without starting the engine. For my old Accord, it's done by turning the key counterclockwise one notch - the dashboard lights up but the engine stops. This trick is especially useful at railway crossings while waiting for the gate, as it complies with traffic rules and reduces carbon buildup. I once tried it at a highway toll booth - the fuel saved in five minutes was enough to drive one kilometer. Note: for cars with aging batteries, don't exceed ten minutes to avoid battery drain preventing engine start.

Use this trick every day to pick up kids from school! Temporary parking means turning the ignition switch back to the first position. For example, when queuing at the school gate, the engine stops but hazard lights can still be turned on. Our moms' group tested it: In summer, if waiting with AC on for over two minutes, you must turn off the engine, otherwise exhaust fumes are harmful to health. New cars are smarter now—the auto start-stop function essentially follows the same principle. However, for older cars, be aware that the steering wheel locks after turning off the engine, so remember to power on before moving the car.
