The method for the Nissan Teana to automatically lock the doors is: in the vehicle settings, select the 'auto-lock while driving' option and set a speed threshold. When the vehicle exceeds this preset speed, the doors will automatically lock. Additionally, for the 'auto-unlock' function, you can choose to unlock when shifting to P gear or when turning off the engine. The purpose of the auto-lock feature is anti-theft; the doors only lock after reaching a certain speed to prevent door-pulling robberies during traffic jams or at red lights, providing a certain level of security. Taking the Teana 2021 2.0LXE Fashion Edition as an example: it is a mid-size car launched by Dongfeng Nissan, with dimensions of 4901mm in length, 1850mm in width, and 1450mm in height, and a wheelbase of 2825mm. It is equipped with a 2.0L naturally aspirated engine with a maximum power of 115kw, paired with a CVT continuously variable transmission.

I've been driving a Nissan Teana for several years, and the auto-lock feature is incredibly practical and not complicated to set up. Typically, you operate it through the vehicle settings menu: after starting the car, locate the settings option on the dashboard or center screen, scroll to the door or lock section, and enable the auto-lock function. The doors will automatically lock when the speed exceeds around 15km/h, saving you the hassle of manual operation—especially useful when you're busy and might forget, preventing theft or accidental door openings by children. The setup path might vary slightly across different model years of the Teana; for my 2020 model, it's done through menu navigation. I recommend setting it up while parked before driving to avoid distractions. This feature also enhances driving safety by reducing the risk of doors popping open after a collision. Regular system maintenance ensures better reliability.

As a family driver who frequently takes kids out, I particularly value the Nissan Teana's auto-lock feature for its simple setup and enhanced safety. Here's how I operate it: Press the setup button on the main control panel to enter the vehicle menu, locate the door lock option to enable automatic locking. Once activated, the doors automatically lock when the speed increases, eliminating the hassle of forgetting to lock or accidental door openings – especially reassuring when kids are fidgeting in the backseat. I find this feature more user-friendly than manual locking, making daily commutes and grocery runs with full hands worry-free. However, it's advisable to check the user manual for model-specific details before setup, as configurations may vary slightly (e.g., some Teana model years bury this setting deeper in the system). Enabling auto-lock also boosts anti-theft performance, making every trip more convenient and secure.

Setting up the Nissan Teana's automatic door locking is simple and quick. I usually do it through the center console screen: start the car, tap the settings menu, select the vehicle options and open the door lock settings, then enable the auto-lock switch. The doors will lock automatically when the vehicle reaches the set speed, eliminating the need for manual operation. This smart feature is particularly convenient during busy driving situations, such as highway driving where you don't have to worry about forgetting to lock the doors, and it also reduces accident risks. From personal experience, setting it up before test driving is the safest approach, and details may vary by model year—consult the owner's manual for specifics.
