To turn on the power without pressing the brake, press the one-touch start button once. To turn off the power, press the one-touch start button again without pressing the brake. For cars without a one-touch start system, simply turn the key to the 'lock' position. The one-touch start system is paired with a keyless entry system, which is a proximity key. With the key on your person and near the car, you can open the door and start the car by pressing the one-touch start button without ever needing to take out the key. Generally, to start the car with one-touch start, press the button without pressing the brake. Similarly, to turn off the power, press the button once, ensuring the gear is in the 'P' (Park) position. Car power, also known as a power inverter, is a device that converts DC12V direct current into AC220V alternating current, the same as household electricity, for use with general appliances. It serves as a convenient power converter. Car power systems are designed with external usage conditions in mind. They automatically shut down for protection in cases of overload or short circuits. The output voltage of the car power system is stabilized through its own feedback mechanism, ensuring that the voltage variation between no-load and rated conditions is less than 10V.

Turning off the car's power is actually quite simple. I memorized the basic steps while driving: First, park the car in a safe location, such as the roadside or a parking spot, and engage the handbrake to prevent rolling. Then, shift to P (Park) or neutral—this is especially important for automatic transmission vehicles. For manual transmissions, press the clutch pedal. Next, turn off the engine. For older cars, remove the key; for newer cars, press the start/stop button. Once the engine shuts off, all systems, including the air conditioning and headlights, will automatically turn off. After shutting down, don’t forget to check if the headlights or other electrical devices are turned off—otherwise, the battery can drain easily. I once forgot to turn off the lights and couldn’t start the car the next day. Finally, lock the doors, and once the anti-theft system activates, you're done. I also recommend checking the battery status regularly. If the car won’t be used for an extended period, it’s best to disconnect the negative terminal of the battery to prevent power leakage.

Turning off the power must be done safely without negligence. I always emphasize parking on level ground, shifting to P gear, and engaging the handbrake before proceeding. Shutting down the engine is a crucial step—simply remove the key or press the button, and the vehicle's internal components will gradually power down. Before turning off the ignition, ensure all auxiliary devices like music or air conditioning are switched off to prevent battery over-discharge and damage. Extra caution is needed when parking on slopes—shift to a lower gear or use wheel chocks for added security. I frequently remind myself to lock the doors to prevent theft. After powering off, the system enters sleep mode, with indicator lights remaining on to signal safety.

The core of turning off the car's power is to prevent battery drain: park the car, turn off the engine, and shut down all electrical accessories; beginners often forget to turn off the lights, leading to a dead battery, so extra attention is needed; check the response when the key is removed or the button is pressed to ensure the system is completely disconnected; regular maintenance can extend battery life, and disconnecting the negative terminal when the car is not in use is a safer measure—a few simple steps can save a lot of trouble.
