Is it necessary to press the brake for one-key start/stop?

One-key start/stop does not require pressing the brake, but it is necessary to press the brake pedal when starting the engine. If the brake pedal is not pressed during startup, the engine cannot be started. Many vehicles are equipped with one-key start systems, which enhance convenience and user experience. For cars with this system, the driver only needs to carry the key fob, get in the car without inserting or turning a key, and simply press the brake pedal along with the start button to ignite the engine. Some vehicles not only feature one-key start but also come with keyless entry, allowing the owner to unlock the doors without pressing any buttons on the remote.

I've been driving for over a decade and have used various push-button start systems. When turning off the engine, you usually don't need to press the brake pedal - just push the start button directly. This differs from starting the engine, which requires brake pedal depression to prevent accidental movement. However, shutting down the engine only requires stopping it, making additional brake pedal input unnecessary. Remember to ensure the vehicle is parked on level ground in P (Park) position before turning off for added safety. I've seen people confuse these operations - mainly because starting requires brake pedal input, leading them to think stopping does too. Developing good habits can prevent incorrect operations. If the button is accidentally pressed while driving, the vehicle will either warn you or handle it safely. Overall, push-button start systems are designed with great ergonomics - turning off the engine is simple and straightforward without worrying about complicated procedures.

From a safety perspective, pressing the brake pedal is absolutely unnecessary for one-button engine start/stop. Pressing the brake during startup is to prevent vehicle movement when the engine starts, but the shutdown process is the opposite—engine stoppage doesn't pose a movement risk. Having tested various models, all require only pressing the button to shut down without brake involvement. The safety reminder is to ensure the gear is in P or N position before exiting after shutdown. Some vehicles will sound an alarm if the gear isn't properly positioned, where pressing the brake won't help. The key is to familiarize yourself with the vehicle manual, as certain premium models might require additional operations in specific modes, but 99% of cases don't need brake pressing. This design reduces misoperation probability and enhances daily convenience.

When I first bought my car, I was also unfamiliar with the one-button start/stop. Don't worry, you usually don't need to press the brake to turn off the engine—just press the button once. Starting the engine requires pressing the brake because it's for safety. Turning off the engine is simple—just press the button and the engine stops. However, if the car isn't fully stopped or the gear isn't in P (Park), there might be issues. So, I recommend always stopping the car, shifting to P, and then turning off the engine—safety first. The whole process takes just a few seconds, and as a beginner, you'll get used to it after practicing a few times.
