What is the correct start-stop sequence for keyless ignition?

When using keyless ignition, you need to press the foot brake and press the start-stop button to ignite the car. Introduction to the keyless ignition system: The keyless ignition system allows you to start the vehicle without inserting or turning a key. As long as the smart key is inside the car, pressing the START button can directly ignite or turn off the engine. The keyless ignition system is a more advanced configuration than the keyless entry system. Vehicles equipped with the keyless ignition system also have the keyless entry system, but vehicles with the keyless entry system may not necessarily have the keyless ignition system. Keyless ignition steps: First, after the driver sits in the driver's seat, without pressing the brake, press the start button once—the ACC light will turn on. Next, the driver presses the brake and presses the one-touch start button to ignite the engine. Then, release the foot brake; you can choose to warm up the car in place. Press the foot brake again, shift into D gear, release the handbrake, and finally, slowly release the foot brake while gently pressing the accelerator to complete the start.
After driving cars with one-button start for so many years, I've summarized the correct sequence: Before starting the engine, you must firmly press the brake pedal, then press the start button to get the engine running; When stopping, first make sure the vehicle is completely stationary, shift into P gear (automatic transmission) or N gear (manual transmission), then press the button to turn off the engine. The system is designed with a brake sensor to prevent accidental starts and a gear position sensor to confirm a safe shutdown position, avoiding vehicle slippage or unintended movement. If you press the button without stepping on the brake, it may only activate the power supply and enter accessory mode, without starting the engine, which drains the battery and is impractical. Forgetting to shift into P gear when stopping may trigger an alarm. I always remind my novice friends to practice more, as this sequence can protect the starter motor and transmission, extending the lifespan of the components.
As someone who prioritizes safety, I pay special attention to the keyless start-stop procedure: To start the engine, firmly press the brake pedal first, then press the ignition button to ensure the car doesn't lurch forward unexpectedly. After coming to a complete stop, shift into P (Park) before pressing the button to turn off the engine, preventing any rolling incidents. This sequence relies on the electronic system monitoring brake status and gear signals for safety—for example, failing to press the brake may allow the car to start under unsafe conditions, while ignoring P (Park) when turning off could damage the transmission. Through testing across multiple car models, I've found the operation consistent. Making it a habit enhances driving peace of mind and reduces unexpected risks. When parking on slopes, I additionally engage the handbrake for extra security. Remember, simple actions protect everyone!
