Initializing after a power failure
After a power failure during the opening or closing process, the roof can only be operated to a limited extent.
Initializing the system
The system can be initialized when the vehicle is stationary and the engine is running.
Danger of pinching
Monitor the closing process and make sure that the closing path of the glass sunroof is clear; otherwise, injuries may result.

Press the switch up and hold it until the initialization is complete:
- Initialization begins within 15 seconds and is completed when the sunroof and sliding visor are completely closed.
- The roof closes without pinch protection.
