is free of snow and ice. Otherwise, malfunc-
tions may occur.
Do not allow anything to protrude from the
sliding sunroof. Otherwise, the seals could be damaged.

usual airflow noises when the sliding sunroof is
open. They are caused by minor pressure fluc-
tuations in the vehicle interior. Change the posi- tion of the sliding sunroof or open a side window
slightly. This will lessen or eliminate the noise. Sliding sunroof reversing feature

matic reversing feature. If an object blocks or
restricts the sliding sunroof during the closing
process, the sliding sunroof opens again auto-
matically. The automatic reversing feature is,
however, only an aid and is no substitute for your attention when closing the sliding roof. Sliding sunroof
