GWARNING
At high speeds the raised sliding sunroof auto-
matically lowers slightly at the rear. This could
trap you or other persons. There is a risk of
injury. Make sure that nobody reaches into
the sweep of the sliding sunroof whilst the
vehicle is in motion.
If somebody becomes trapped, immediately
pull back the sliding sunroof switch. The slid-
ing sunroof lifts during opening.
!Only open the sliding sunroof if it is free of
snow and ice. Otherwise, malfunctions may
occur.

sliding sunroof. Otherwise, the seals could
be damaged.
!The weather can change abruptly. It could
start to rain or snow. Make sure that the
sliding sunroof is closed when you leave the
vehicle. The vehicle electronics can be
damaged if water enters the vehicle inte-
rior.
Resonance noises can occur in addition to the 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.
Sliding sunroof reversing feature
In the following section, the term "sliding sun-
roof" refers to the panorama roof with power
tilt/sliding panel.
The sliding sunroof is equipped with an auto-
matic reversing feature. If a solid object
blocks or restricts the sliding sunroof during
the closing process, the sliding sunroof opens
again automatically. The automatic reversing
feature is only an aid and is no substitute for
your attention when closing the sliding roof.
GWARNING
The reversing feature does not react:
Rto soft, light and thin objects, e.g. small fin-
gers
Rover the last 1/6 in (4 mm) of the closing
movement
Rduring resetting
Rwhen closing the sliding sunroof again man- ually immediately after automatic reversing
This means that the reversing feature cannot
prevent someone being trapped in these sit-
uations. There is a risk of injury.
Make sure that no body parts are in close
proximity during the closing procedure.
If somebody becomes trapped:
Rrelease the switch immediately, or
Rpress the switch in any direction during the
automatic closing process
