wise, the closing action may not stop in certain
situations, e.g., if thin objects are present.
◀
Window accessories
Do not install any accessories in the range
of movement of the windows; otherwise, the
pinch protection system will be impaired.◀
Closing without the pinch protection
system
Danger of pinching
Monitor the closing process and make
sure that the closing path of the window is clear;
otherwise, injuries may result.◀
For example, if there is an external danger or if
ice on the windows prevents a window from
closing normally, proceed as follows:
1. Pull the switch past the resistance point and
hold it there.
Pinch protection is limited and the window
reopens

slightly if the closing force exceeds
a certain value.
2. Pull the switch past the resistance point
again within approx. 4 seconds and hold it
there.
The window closes without pinch protec‐
tion.
Convertible top
General information
The convertible top can be opened or closed at
speeds up to approx. 25 mph/40 km/h.
If the vehicle is accelerated above a speed of
approx. 30 mph/50 km/h while the convertible
top is being moved, the convertible top move‐
ment stops.
Tips about the convertible top:
▷ If possible, close the convertible top when
the vehicle is parked. A closed convertible
top protects it from weather-related dam‐
age and to some extent from theft. ▷
Event when the convertible top is closed,
only

store valuables in the locked cargo area.
▷ At higher speeds, vacuum produced in the
passenger compartment cause the conver‐
tible top to begin to flatten. Increase the
amount

of air via the automatic climate con‐
trol so that no vacuum is produced in the ve‐
hicle.
Notes
The
trunk lid cannot be opened if the convertible
top is not fully opened or closed.
Safety information about the convertible
top
▷ With temperatures below +14 ℉/-10 ℃ do
not open the convertible top; otherwise
damages could result.
▷ Do not leave the open convertible top in the
convertible top well longer than one day
while the top is still wet; otherwise, damage
could result due to moisture.
▷ The convertible top pivots up during open‐
ing

and closing. When the top is moved, e.g.
in garages, make sure that there is a mini‐
mum height of 79 inches/2 meters; other‐
wise, it damages may result.
▷ Do not place any objects on the convertible
top, otherwise, they could fall and cause
damage or injuries.
▷ When the rollover protection system is ex‐
tended, do not under any circumstances
move the convertible top.
▷ Always open or close the convertible top
completely.

Convertible top and convertible
top well storage cover are locked in the final
positions. Driving with the convertible tope
or convertible top well storage cover un‐
locked can result in damage.
▷ Do not reach into the convertible top mech‐
anism

during the opening and closing oper‐
ation. Keep children away from the opening
path of the convertible top, otherwise, there
is a risk of injury. Seite 45
