To set the auto-lock function for the Excelle, press the lock button for about 5 seconds until the hazard warning lights flash twice, indicating successful activation. The Excelle is an entry-level family sedan introduced by SAIC-GM Buick. Taking the 2020 Buick Excelle as an example, its body dimensions are: length 4468mm, width 1765mm, height 1469mm, with a wheelbase of 2611mm and a fuel tank capacity of 40 liters. The 2020 Buick Excelle is equipped with a 1.3L naturally aspirated engine, delivering a maximum power of 79kW and a maximum torque of 133Nm, paired with a 5-speed manual transmission.

I remember setting the automatic locking function for the Excelle was quite simple. Having driven for over a decade, I've encountered this issue often. Just sit in the driver's seat, close all doors properly, and then turn on the ignition without pressing the brake—meaning powering up the car without starting the engine. Next, press and hold the unlock button on the door for about five to six seconds until you hear a beep or see the dashboard light flash, which means the setting is successful. After that, the doors will automatically lock when the car reaches around 10-20 km/h, providing great security against theft. A friend of mine failed the first time setting it up on his new car, but later found out it was because the door wasn't fully closed or the battery was low—just a simple retry fixed it. If you're still unsure, it's best to check your car's manual, as there might be slight variations in the setup process for different model years of the Excelle, but this method solves 90% of the issues. Don't worry, it's not too complicated—just a minor daily adjustment to enhance driving convenience.

Setting up the auto-lock feature requires step-by-step execution: First, ensure all doors are securely closed, including the trunk. Then, enter the car and turn the key to the ACC position without starting the engine. Locate the unlock button on the driver's side door handle or the center console, press and hold it firmly for about 4-5 seconds until you hear a beep or see the lights flash before releasing. Now, when the car starts and accelerates to around 20 km/h, the doors will automatically lock. The key is not to rush the process, as the system may fail to detect the signal. I've seen owners complain about malfunctions, mostly due to not holding the button long enough or incorrect ignition positioning—just repeat the steps and it should work. Additionally, regularly check if this feature is functioning, especially after maintenance, to avoid issues during long trips. It's a simple process that takes just 2-3 minutes, significantly enhancing driving safety.

Setting the auto-lock feature on the Excelle is quite simple and easy to learn: turn the key without starting the engine, then press and hold the unlock button for a few seconds to confirm. Personally, I'm more concerned about the safety implications of this feature, especially when driving with kids or traveling to unfamiliar places, as it helps prevent accidental door openings or theft. Remember to test it after setup by driving until the doors lock at speed—it's convenient and worry-free. If it doesn't respond, try the procedure again or check the battery; don't worry about complexity.

The automatic locking function operates via the speed sensor, and setting it up on the Excelle is incredibly simple. After getting in the car and sitting down, turn on the power without starting the engine, then press and hold the unlock button for five seconds until you hear a confirmation sound to complete the setup. The principle is that the system receives the signal and automatically activates the door locks. I've seen other cars with different setup menus, but the Excelle basically just uses this one method. After setting it up, test it by driving on the road—the doors will lock once the speed reaches the required threshold. If you encounter any issues, consult the manual or ask a repair shop, and don't spend too much time troubleshooting to avoid delaying your trip.
