What is the hidden function of the horn sound when locking the Tiguan L?

[OEverly]

Here is the introduction to the hidden function of the horn sound when locking the Tiguan L: 1. One-touch window control via remote key: This function needs to be manually activated and is a hidden feature. Without activation, the Tiguan L's key cannot remotely control the windows. 2. Automatic braking when reversing: Reverse radar and camera have become standard features in most cars, but automatic braking when reversing is not available in all vehicles. Needless to say, this function is very practical and can effectively avoid many accidents and dangers. According to tests, the Tiguan L 2019 Panorama Comfort Edition and above models have this function. For lower trim levels, you can test whether this function is available.
