How to Turn Off One-Key Start?
3 Answers
The method to turn off one-key start: First, disable the start-stop function on the instrument panel to the right of the steering wheel. The switch indicator light should be off, and the start-stop function icon on the instrument panel should not have a slash. Then, drive in D gear for a while. One-key start, also known as keyless start, refers to pressing the AC button to start or stop the vehicle when it is in a stationary state. For safety reasons, the AC button defaults to the factory settings while driving, making operation more convenient and efficient, and reducing the frequency of needing to handle the car key. Features of one-key start: 1. Stay within the monitoring range, and the owner can directly start the car door by carrying the sensing device card, eliminating the need to search for the car key; 2. Whenever the owner opens the car door and gets inside, they need to press the brake and lightly press the one-key start button to start the engine; 3. One-key start has all the functions of an anti-theft device, and also includes unique features such as a microcomputer automatically closing windows and opening the trunk.
Having driven a car with one-button start for six years, I was initially confused by this issue too. The key is understanding the system logic—turning off the engine doesn't depend on the start button itself. The correct procedure is: after the vehicle comes to a complete stop, shift into P or N gear (some models allow neutral), fully release the accelerator pedal, then press the start button once to power off. Important: never attempt this while driving! In emergencies requiring immediate shutdown, quickly press the button twice consecutively or hold for 3 seconds (refer to your vehicle's manual—procedures vary). If the transmission remains in D gear, the system will usually force shutdown. After turning off, always check the dashboard to confirm all indicator lights are off for successful shutdown. Common beginner mistakes include pressing the button without firm brake pedal pressure (system won't respond) or improper gear selection leading to incomplete shutdown.
Last time while waiting for someone in the supermarket parking lot, I tried keeping the engine running but turning off the AC. The beauty of one-button start systems lies in their layered functionality: a light press without braking powers up the infotainment for radio; holding the brake with a short press ignites the engine; while shutdown depends on gear position—it must be in P (or neutral for manuals), then one button press initiates automatic shutdown. For quick shopping trips, simply engaging P gear plus handbrake and walking over 3 meters away with the key will trigger auto shutdown/lock on most models. Once in my friend's EV, pressing start in D gear only turned off multimedia while the motor kept running—I immediately corrected to P gear, highlighting significant manufacturer differences in this design detail.
