Can the Engine Start Without Pressing the Brake in One-Key Start?
2 Answers
No, the engine cannot start. One-key start requires pressing the brake to ignite and start the engine, which is a safety design in cars to prevent accidental activation of the switch that could cause the vehicle to suddenly move forward. When the vehicle is turned off, pressing and holding the one-key start button for 3 seconds without pressing the brake will only power on the vehicle without starting it. Some models require pressing the ignition switch twice consecutively. Below are the correct steps for starting and stopping the engine with one-key start: 1. After the driver sits in the driver's seat, press the start button once—the ACC light will turn on. Press it once more, and the vehicle will perform a self-check. 2. Press the brake and press the one-key start button to ignite and start the engine. 3. Release the foot brake; you can choose to warm up the engine in place, with the duration depending on the environment. 4. Press the brake again, shift to D gear, and release the handbrake (for electronic handbrakes, simply press the button briefly). 5. Slowly release the foot brake, gently press the accelerator, and the vehicle will start moving.
Last time I borrowed my friend's car, I made this exact mistake. Pressing the start button without stepping on the brake only powered up the electronics—the engine didn't start, and the dashboard lit up with various warning lights. At this point, the windows and stereo would work, but the engine remained completely off. Only by pressing the brake pedal and then hitting the start button could I hear the engine ignite. It took me several tries to figure this out. Veteran drivers might find it obvious, but it's genuinely confusing for beginners. The principle is simple: it's a safety measure designed by manufacturers to prevent accidents caused by accidental operation. As a side note, leaving the car powered on without starting the engine for extended periods drains the battery heavily—I once nearly ruined the battery doing just that.
