Opening, closing
Ignition key in position 1 or higher:
>Press the switch downward to the resis-
tance point.
The window continues to open as long as
you press the switch.
>Press the switch beyond the resistance
point.
The window opens automatically. Press the
switch again to stop the opening move-
ment.
You can close the window in the same manner
by pulling the switch upward.
If you wish, you can have this special fea-
ture activated/deactivated.<
After switching off the ignition
You can still open or close the windows for
approx. 1 minute, as long as no one opens any
of the doors.
For convenience operation via the remote con-
trol or the door lock, refer to page19 or20,
respectively.
Pinch protection system
If the closing force exceeds a certain value while
a window is being raised, the system responds
by stopping the window and then retracting it a
short distance.
Despite the pinch protection system
check and clear the window's travel path
prior to closing it, otherwise the safety system
might fail to detect certain kinds of obstruc-
tions, such as thin objects, and the window
would continue closing.
Do not install any accessories within the win-dows' range of movement; otherwise the pinch
protection system could be impaired.<
The closing force can change as a result
of extreme temperature fluctuations. The
window then opens slightly after closing even if
there is no obstacle within the window's travel
path. If this occurs, override the pinch protec-
tion system.<
Pulling the switch beyond the resistance point
and holding it there overrides and deactivates
the pinch protection system.
After a power supply interruption
After a power supply interruption, for instance
after disconnecting the battery, the pinch pro-
tection system must be reinitialized.
Roadster: when the convertible top has
been stored in the convertible top com-
partment for an extended period of time, e.g. in
the winter months because the hardtop was
being used, it may also be necessary to reinitial-
ize the pinch protection system.<
Ensure that the doors and the Roadster's con-
vertible top are closed before initializing.
1.Open the window completely.
2.Press the switch 4 times within approx.
10 seconds.
Afterward, perform the following procedure
twice for each window:
1.Close the window completely by pulling the
switch.
2.After the window is closed, keep pulling the
switch for approx. 2 seconds.
3.Open the window completely by pressing
the switch.
Roadster: manual convertible
top
The fabric top offers perfect protection against
the weather and can be opened easily and
quickly by one person alone.
