functions 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
fluctuations in the vehicle interior. Change
the position of the sliding sunroof or open a
side window slightly to reduce or eliminate
these noises.
Only for vehicles with panorama sliding
sunroof: G
WARNING
At high speeds the raised sliding sunroof auto- matically lowers slightly at the rear. This could
