Opening and closing

!Only open the sliding sunroof if it is free of
snow and ice. Otherwise, malfunctions may
occur.
Do not allow anything to protrude from the
sliding sunroof. Otherwise, the seals could be
damaged.
!The weather can change abruptly. It could

ing sunroof is closed when you leave the vehi-
cle. The vehicle electronics can be damaged if
water enters the vehicle interior.
Resonance noises can occur in addition to the
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.

If somebody becomes trapped, immediately
pull back the sliding sunroof switch. The slid-
ing sunroof lifts during opening.
