The side windows are equipped with an auto- matic reversing feature. If a solid object
blocks or restricts a side window from trav-
eling upwards during the automatic closing
process, the side window opens again auto-
matically. During the manual closing process,
the side window only opens again automati-
cally after the corresponding switch is
released. The automatic reversing feature is
only an aid and is no substitute for your atten- tion when closing a side window. G

R to soft, light and thin objects, e.g. small fin-
gers
