cle. The vehicle electronics can be damaged if

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 to reduce or eliminate these noises.

matic reversing feature. If a solid object blocks or restricts the sliding sunroof during the closing

gers
