when the windshield is dry. Dust that
accumulates on a windshield might
scratch the glass and/or damage the
wiper blades when wiping occurs on a dry
windshield. If it is necessary to operate
the windshield wipers in dry weather
conditions, always operate the
windshield wipers with windshield
washer fluid.
! If anything blocks the windshield
wipers (leaves, snow, etc.), switch them
off immediately.
For safety reasons, stop the vehicle in a
safe location and

intermittent setting when the vehicle is
taken to an automatic car wash or during
windshield cleaning. Windshield wipers
will operate in the presence of water
sprayed on the windshield, and
windshield wipers may be damaged as a
result.
! Vehicles with rain-light sensor*:
If you have set intermittent wiping, dirt
on the surface of the sensor or optical
effects may cause the windshield wipers
to wipe in an undesired fashion. This
could then damage the windshield wiper
blades or scratch the windshield. You
should therefore switch off the
windshield wipers when weather
conditions are dry.
X Make sure the key is in starter switch
position 1.
X Activating intermittent wiping: Turn the
wiper switch to position 0004.

fabric may tear. This may result in an
opening in the roof.
In a vehicle rollover, occupants not
wearing their seat belts or not wearing
them properly may be thrown out of the
opening. Such an opening also presents a

transport any objects with sharp edges
which can stick out of the retractable
soft top.
Do not open the retractable soft top if
there is snow or ice on the roof, as this
could result in malfunctions.
If you cannot open or close the
retractable soft top due to a malfunction
