Do You Need to Press the Brake for One-Button Start in Automatic Transmission?
2 Answers
Automatic transmission one-button start requires pressing the brake. Definition of One-Button Start: The car one-button start belongs to the keyless start system, which upgrades the traditional mechanical start to a button start. In addition to some original manufacturer model configurations, it can also be installed at the original car key lock. Precautions for Using One-Button Start: Using one-button start when the car is in P or N gear does not harm the engine, but turning off the engine while the car is in gear can cause some damage to the vehicle. Additionally, for safety reasons, it is recommended to press the brake before using one-button start to turn off the engine. Moreover, one-button start models must be turned off in P gear to completely cut off the power.
When I bought my new car with a one-touch start feature, I didn't understand it at first. After trying a few times, I realized the engine wouldn't start without pressing the brake pedal—only the sound of the dashboard powering on could be heard. Automatic transmission vehicles are designed this way for safety, preventing accidental movement due to mishandling, such as when the gear is in R (Reverse) or if a child is playing with the controls. Now, I've developed the habit of pressing the brake pedal first before pressing the start button, ensuring the one-touch start works properly. Sometimes, in cold weather, the brake pedal feels stiff, and I have to press it firmly all the way down for it to work. If the start fails, besides checking whether the key is inside the car, I also look to see if the brake lights are on. If they aren't, it might be an issue with the brake switch, requiring a diagnosis at the repair shop. Understanding these details makes driving safer and more efficient.
