sunroof lowers slightly but remains raised
at the rear.

When the SmartKey is in position 0in the
ignition lock or is removed, the sliding sunroof
closes automatically:
R if it starts to rain
R at extreme outside temperatures
R after six hours
R if there is a malfunction in the power supply
The sliding sunroof remains raised at the rear
in order to allow ventilation of the vehicle
interior.
iIf the sliding sunroof is obstructed while
being closed by the rain-closing feature, it
opens again slightly. The rain-closing fea-
ture is then deactivated.

Operating the roller sunblind for the
sliding sunroof
Important safety notes
GWARNING
When opening or closing the roller sunblind,
parts of the body could be trapped between
the roller sunblind and the frame or sliding
sunroof. There is a risk of injury.
When opening or closing make sure that no
parts of the body are in the sweep of the roller sunblind.
If somebody becomes trapped:
R release the switch immediately, or
R during automatic operation, push the
switch briefly in any direction
The opening or closing procedure will be stop-
ped.
The roller sunblind shields the vehicle interior from sunlight. The roller sunblind can only be
opened and closed when the sliding sunroof
is closed.
Roller sunblind reversing feature
The roller sunblind is equipped with an auto-
matic reversing feature. If a solid object
blocks or restricts the roller sunblind during
the closing process, the roller sunblind opens
again automatically. The automatic reversing
feature is only an aid and is not a substitute
for your attentiveness to the roller sunblind
while it is closing.
GWARNING
The reversing feature does not react:
R to soft, light and thin objects, e.g. small fin-
gers
R when closing the roller sunblind 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 parts of the
body are in the sweep of the roller sunblind.
If somebody becomes trapped:
R release the switch immediately, or
R during automatic operation, push the
switch briefly in any direction
