Old Mazda6 auto-lock setting method is: 1. Turn the ignition switch to the ON position (power on but engine not started); 2. Press and hold the lock button on the driver's door for about 5 seconds until you hear a beep, then release the lock button; 3. Press the unlock button 5 times consecutively until you hear 5 confirmation beeps. Taking the 2013 Mazda6 as an example, its body structure is a 4-door 5-seater sedan with dimensions of: length 4670mm, width 1780mm, height 1435mm, wheelbase 2675mm, front track 1540mm, rear track 1540mm, fuel tank capacity 64L, and curb weight 1427kg.

Having driven an old Mazda6 for over a decade, I'm quite familiar with setting up the auto-locking feature. Here's how it works: Get seated, close all doors, turn the key to the ACC position without starting the engine. Then, press and hold the unlock button on the driver's door for about 3-4 seconds until you hear a beep, indicating successful setup. During a test drive, the doors will automatically lock with a click when speed exceeds 10 km/h, effectively preventing accidental openings. Why bother? This feature acts as a lifesaver when kids fidget at high speeds or during sharp turns. Also, remember to check the fuse during routine maintenance to ensure the setting remains functional. The whole process takes just minutes – convenient and safe.

I often tinker with cars, and setting up auto-lock is super simple and fun. Sit in the driver's seat, make sure all doors are closed, turn the key to the ON position (don't start the engine), then press and hold the unlock button on the door panel for a few seconds. Wait for the confirmation beep, and you're done! Some models even allow customizing the speed trigger point, like setting it to lock at 15 km/h. After setup, take a short drive to test it—the satisfying click is awesome. If it doesn’t work, don’t panic; try different button combinations or check the user manual. This feature is supported on most older Mazda6 models, though occasionally low battery voltage might affect the setup. If needed, charge the battery and try again.

As a safety-conscious driver, I must emphasize the importance of setting up auto-locking. The procedure is simple: close all doors, turn the key to the ON position, hold the unlock button for a few seconds until the confirmation beep sounds. Once activated, doors will automatically lock when driving, significantly reducing accidental risks. It's advisable to check the system during regular vehicle maintenance and remind passengers not to manually unlock doors while moving. Minimal maintenance provides substantial safety benefits.
