How to turn on the Jetta's car locking sound?

If you want the horn to sound when locking the car, connect the alarm's trigger signal wire to the horn wire to enable this function. After enabling this feature, when you hear the horn sound upon locking, you don't need to worry about the doors not being locked.

The locking sound is a useful indicator to confirm whether the Jetta's doors are securely locked, and I frequently use this feature. The activation method is simple: take out the remote key, press and hold both the unlock and lock buttons simultaneously for about 5-7 seconds until the car lights flash once or a slight beep is heard, indicating successful activation. If there is no response, it may default to the off state, requiring an in-car operation—sit in the driver's seat without starting the engine, turn the key to the power-on position, and use the buttons on the steering wheel or the dashboard menu to navigate to the comfort settings under vehicle settings, then check the box to enable the locking feedback sound. Remember to check the key battery's charge level; low battery power can cause malfunction—if the sound doesn't activate, try replacing the battery. Additionally, developing the habit of enabling it can help avoid locking mistakes, making it very practical.
