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
The closing process is stopped. Operating the panorama sliding sun-
roof
Opening and closing :
To raise
; To open
= To close/lower
The panorama sliding sunroof can only be oper-
ated when the roller sunblind is open.
X Turn the key to position 1or2 in the igni-
tion lock (Y page 144).
X Press or pull the 3switch in the corre-
sponding direction.
If you press/pull the 3switch beyond the
pressure point, automatic operation is started in
the corresponding direction. You can stop auto-
matic operation by pressing/pulling again.
After opening the sliding sunroof, the roller sun- blind automatically closes slightly. This reduces drafts in the vehicle interior.
If the sliding sunroof is raised at the rear, it
automatically lowers slightly at higher speeds.
The noise level in the vehicle interior is reduced
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
key. This function remains active for five
minutes or until you open a front door.
The sliding sunroof cannot be opened if a roof
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
