The side windows are equipped with an auto- matic reversing feature. If a solid object
blocks or restricts a side window during the
closing process, the side window opens again automatically. However, the automatic
reversing feature is only an aid and does not
relieve you of the responsibility of paying
attention when closing a side window. G
