Why Can't the Brake Be Pressed When Using One-Button Start?
2 Answers
One-button start brake cannot be pressed because the driver did not follow the correct steps to start the car. For cars equipped with one-button start, the correct operation is to first press the one-button start once, then press the brake, and simultaneously press the one-button start key again to complete the car's startup. When starting a car with one-button start function, it is necessary to press the one-button start button once before pressing the brake. The purpose is to allow the car to perform a quality check before starting. After the self-check is completed, you can press the one-button start button again and simultaneously press the brake pedal. At this time, the situation where the brake pedal cannot be pressed will not occur.
I've been driving a car with push-button start for many years and have encountered the situation where the brake pedal becomes hard to press more than once or twice. Usually, when the engine is not running, the brake system lacks vacuum assist, making the brake pedal as hard as iron—it's normal that you can't press it. My advice is not to panic; try pressing the brake pedal deeply a few times until you feel some looseness, then press the start button to start the car. If the pedal remains hard after starting, it might be due to a faulty vacuum pump, a dead battery, or a malfunction in the push-button start signal. In such cases, it's best not to keep trying; immediately turn off the engine and check the key position to avoid compromising safety—I once experienced a vacuum tube leak, which took only half an hour to fix at the repair shop. Regularly pay attention to battery maintenance and early warnings of minor faults.
