Should the one-button start be held down or just pressed once?

One-button start requires only a single press. It is a button device installed in smart cars to simplify the ignition process, and it also includes an engine shut-off function. The one-button start system features: automatic unlocking, automatic locking, automatic window closing, automatic anti-theft, one-button start, one-button shut-off, automatic locking before driving, automatic unlocking when parking and shutting off the engine, and trunk opening functionality. The steps to start a car with one-button start are: 1. Sit in the driver's seat and press the start button, at which point the ACC light turns on, then press again for the vehicle to perform a self-check; 2. Depress the brake pedal and press the one-button start to ignite the engine; 3. Release the foot brake; 4. Press the foot pedal, shift into drive gear, and release the handbrake; 5. Release the foot brake and press the accelerator to complete the starting process.
I've run a repair shop for ten years and often get this question from car owners. The one-touch start button is intelligently designed—no need to hold it down, just a light press suffices. When the system detects the key fob inside the vehicle and you depress the brake or clutch pedal, pressing the button initiates the complete engine startup sequence. Holding it down may accidentally trigger other modes; for instance, some vehicles enter transport mode after a 5-second press. I once had a customer who drained the battery by stubbornly keeping it pressed. The correct method is: depress the brake, lightly tap the button for half a second, and release upon hearing the engine roar. Remember, a brief press equates to turning the key to the ignition position, while exceeding 3 seconds may disrupt the ECU's programming. Veteran drivers swear by one-handed operation—it looks cooler and leaves the other hand free to buckle up!
My driving instructor emphasized this detail when I was getting my license. The one-button start operation is extremely simple: just press the brake pedal and lightly tap the button with your finger—it starts in less than a second. With my dad's old car, I had to turn a key, so when I got a new car, I kept pressing the button for too long out of habit. The salesperson told me that actually harms the car. Now that I'm used to it, I find it super convenient—just sit in the car with the key in my bag, press the brake, and instantly tap the start button. It's even better on rainy days since I don’t have to pull out the key and get wet. Just be careful not to spill drinks on the button—last time, my best friend’s BMW button got stuck because milk tea spilled into the crevices.
