The solar cells in the roof provide energy to operate the ventilation system for the c limate control. It is activated automatically after the
veh ic le is parked. Depending on solar i rradiation , the interior
temperature of the vehicle is lowered in the summer, in the winter
the interior is dehumidified.
So la r pr otec tion with slidi ng glass su n roof
The slid ing glass sun roof is equ ipped with an adjustable sunshade
to reduce the effects of strong sunl ight . The so lar protection can be
moved at the recessed handle to open and close it. To prevent the
vehic le interior from heating up, you should close the solar protec­
tion when you park your vehicle in the sun.
When the roof is

When the roof is closed, the sunshade can be closed manually.
When the roof is
