Do You Need to Press the Brake When Using One-Button Start/Stop?
2 Answers
Cars equipped with a one-button start system do not require pressing the brake pedal when shutting off the engine. Below are the related explanations for one-button start/stop issues: Idle Switch Not Closing: If the engine speed does not increase when the air conditioning is turned on at idle, this fault can be confirmed. The throttle position sensor can be adjusted, repaired, or replaced. Idle Control Valve Malfunction: Check for any operational sound from the idle control valve. If there is no sound, it indicates a malfunction. The idle control valve can be cleaned or replaced, and the idle speed should be reset using a dedicated decoder. Intake Pipe Leakage: If a hissing sound from the intake pipe is heard, it indicates a leak in the intake system. The leak should be located and resealed or the relevant components replaced.
As someone who frequently drives a one-push start model, I've found that stepping on the brake is completely unnecessary when turning off the engine. The one-push start system is designed for the convenience of the driver. During the shutdown process, you only need to lightly press the start button, and the car will automatically turn off the engine without any need to engage the brake pedal. This differs from the requirements when starting the engine, where stepping on the brake is indeed necessary for safety to prevent unintended movement. The reason why stepping on the brake isn't required when shutting down is that the system ensures the gear is in P (Park) or another safe position before executing the shutdown. In my own car, I always make it a habit to confirm the gear is in P before pressing the button to shut down the engine, which takes just a few seconds and is very convenient. If you forget to shift gears and attempt to shut down directly, some cars will automatically alert or sound an alarm to ensure safety. Overall, this design simplifies driving by eliminating extra steps. I also recommend that new drivers familiarize themselves with their car's manual to understand specific operations, as different models may have slight variations, but most modern cars follow this design.
