The voice control is an especially futuristic highlight: using the keyword “Hey Mercedes”, the roof can be extended or retracted, the seat bench can be converted into a comfortable sleeping surface and the electrically driven awning operated along with a diverse range of lighting scenarios. The filling level of the water tank can also be called up. Another revolutionary detail: the automatic window tinting. Liquid crystals integrated into the side windows ensure that the glass becomes opaque and blocks out the light in a matter of moments. This function can also be controlled via voice command, app or the multimedia system.
