Important safety notes
G
WARNING
While opening the side windows, body parts
could become trapped between the side
window and the door frame as the side
window moves. There is a risk of injury.
Make sure that nobody touches the side
window during the opening procedure. If
somebody becomes trapped, release the
switch or pull the switch to close the side
window again. G
WARNING
While opening the side windows, body parts
in the closing area could become trapped.
There is a risk of injury.
Make sure that no body parts are in close
proximity during the closing procedure. If
somebody becomes trapped, release the
switch or press the switch to open the side
window again. G
WARNING
If children operate the side windows they
could become trapped, particularly if they are
left unsupervised. There is a risk of injury. When leaving the vehicle, always take the

leave children unsupervised in the vehicle.
The side windows are equipped with an
automatic reversing feature. If an object
blocks or restricts a side window during the
closing process, the side window opens again
automatically. G
WARNING
The reversing feature does not react:
R to soft, light and thin objects, e.g. small
fingers
R over the last 4 mm of the closing movement
R during resetting
R when closing the side window again
manually immediately after automatic
reversing
This means that the reversing feature cannot
prevent someone being trapped in these
situations. There is a risk of injury.
Make sure that no body parts are in close
proximity during the closing procedure. If
someone becomes trapped, press the switch
to open the side window again.

Important safety notes
G
WARNING
If you do not lock the closed soft top, it may
open during a journey. This could cause you
to lose control of the vehicle. There is a risk
of an accident.
Only drive with the soft top fully open or
locked closed. G
WARNING
If you do not fully open/close the soft top, the
soft-top hydraulics depressurize after a short
time. This causes the soft top to lower unexpectedly and may cause you or others to
be trapped. There is a risk of injury.
Always open or close the soft top completely.
You can open or close the soft top:
R if the vehicle is stationary or
R if the speed does not exceed 30 mph
(50 km/h)
If there is a strong head wind, it may not be
possible to close the soft top fully. In order to
close the soft top fully, reduce speed or stop.
For safety reasons, Mercedes-Benz
recommends that you only open or close the
soft top when the vehicle is stationary. 78
