Important safety notes
In the following section, the term "sliding sun-
roof" refers to the panorama sliding sunroof. G
WARNING
While opening and closing the sliding sunroof, body parts in close proximity could become
trapped. There is a risk of injury.
Make sure that no body parts are in close
proximity during the opening and closing pro- cedures.
If somebody becomes trapped:
R release the switch immediately, or
R during automatic operation, press the
switch briefly in any direction
The opening or closing procedure will be stop- ped. G
WARNING
If children operate the sliding sunroof they
could become trapped, particularly if they are left unsupervised. There is a risk of injury.
When leaving the vehicle, always take the key
with you and lock the vehicle. Never leave
children unattended in the vehicle. G
WARNING
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 panorama sliding sunroof if it
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.
i Resonance noises can occur in addition to
the usual airflow noises when the sliding sun-
roof is open. They are caused by minor pres-
sure fluctuations in the vehicle interior.
Change the position of the sliding sunroof or
open a side window slightly to reduce or elim-
inate these noises. Panorama sliding sunroof

Reversing feature of the sliding sun-
roof
In the following section, the term "sliding sun-
roof" refers to the panorama sliding sunroof.
The sliding sunroof is equipped with an auto-
matic reversing function. If a solid 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. G
WARNING
The reversing feature does not react:
R to soft, light and thin objects, e.g. small fin-
gers
R over the last 4 mm of the closing movement
R during resetting
R when 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.
When closing make sure that no body parts
are in the closing area.
If someone is trapped:
R release the switch immediately or
R press the switch in any direction during the
automatic closing process

as a result.
At low speeds, it rises again automatically.
You can also temporarily deactivate automatic
lowering. To do so, press the 3switch. The
sliding sunroof raises again automatically.
You can continue to operate the sliding sunroof
after switching off the engine or removing the

carrier is fitted. In order to allow ventilation of
the vehicle interior, you can raise the sliding
sunroof.
If contact is made with a roof carrier approved
by Mercedes-Benz, the sliding sunroof lowers
slightly but remains raised at the rear. 102
