How to set the Volvo C30 side mirrors to automatically fold when locking the car?

The vehicle must come with a side mirror folding feature in order to set it.

You can set it up in the small screen of the central control. There's an option for rearview mirror settings. Just select it. If it's in English, you can use a translation tool like Google Translate. Press the menu button to set it up.

Doesn't it automatically fold when you lock the car?
