With the VW T-Roc, you have the option of activating the automatic window closure function in the event of rain, via the on-board network control unit.
The windows and panoramic roof are linked to the rain sensor, so the doors close automatically. The operating mode can be activated or deactivated in the CAR menu on the Discover infotainment system.
