Do You Need to Press the Brake for One-Button Start?
2 Answers
One-button start requires pressing the brake; the vehicle cannot start without pressing the brake. Pressing the brake prevents the car from suddenly moving forward, which is a safety design. Automatic transmission cars with one-button start functionality require pressing the brake pedal before starting, and it is also necessary to ensure the gear is in the P position. Correct operation for one-button start: For models equipped with one-button start, do not press the brake initially when starting. First, press the one-button start key once to power on the vehicle. Wait for the vehicle's self-check to complete, then press the brake pedal. At this point, pressing the one-button start again will start the vehicle. Precautions for one-button start: Pressing the one-button start without pressing the brake powers on the vehicle; pressing the one-button start while pressing the brake starts the engine.
I've driven several cars with push-button start, and all of them required pressing the brake pedal to start. This design prevents accidental activation when the car isn't in park. Once I tried pressing the start button without stepping on the brake, and the car didn't respond—it only started when I pressed the brake. I think this is very reasonable—safety first, after all—to avoid accidentally starting the car while driving or if a child presses the button. If you're driving an automatic transmission car, pressing the brake also ensures it's in neutral, preventing rolling. However, different car models may vary; for example, my Japanese car strictly requires it, while a friend's American car reportedly allows disabling it in the settings. In any case, you'll get used to it, and developing the habit of pressing the brake is very helpful for driving safety.
