Hold down the ignition switch, press the lock button for about 5 seconds until the hazard warning lights flash twice to confirm successful setup. This anti-theft feature enables quick door locking after starting the vehicle, preventing door-pulling robberies during traffic jams or at red lights, providing certain security protection.

I just bought a new car last year and researched the auto-locking settings. For most models, after starting the vehicle, look for "Vehicle Settings" or "Safety Settings" on the central control screen, enter the door lock options, and turn on the "Auto-Lock While Driving" function. Some cars require shifting to D gear and holding the driver's side lock button for 5 seconds until you hear a confirmation beep. This feature is very practical—it automatically locks the doors when the speed exceeds 15 km/h, preventing anyone from pulling the door open at red lights. After setting it up, remember to test it by driving a short distance. If you can't find the option, check the car's manual or visit the 4S dealership for free activation.

I usually enjoy studying automotive electronic systems, and the auto-locking settings actually vary by vehicle. German cars typically enable it in the vehicle settings menu on the steering wheel; Japanese cars may require entering maintenance mode to program it; domestic new cars can usually activate it with one touch on the touchscreen. The principle is that the onboard computer detects the wheel rotation signal to trigger the lock. It's recommended to use it in conjunction with the window anti-pinch function to prevent passengers from getting their hands caught. If the central console doesn't have this option, you can buy an OBD auto-lock device and plug it into the interface under the steering wheel—it takes just three minutes to enable the auto-lock feature, and the compatibility is quite good.

Having sold cars for ten years, I often teach customers to set up this feature. After starting the engine, don't shift gears. Just look at the dashboard menu, select 'Settings - Door Locks - Auto Lock' to turn it on. Some models require operation in the central control screen system settings. Modern vehicles basically come with this feature. Once set, the car will automatically lock with a click about ten seconds after starting. This feature is especially useful in the city, preventing passengers from accidentally opening the door by touching the handle, particularly when traveling with elderly or children. The setup is super simple. If you really can't figure it out, just go to the dealership and let the salesperson help you—it takes just a minute to get it done.
