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.
Hints▷The trunk lid cannot be opened if the
convertible top is not fully opened or
closed.▷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
vehicle interior causes the convertible top
to begin to flutter. Increase the amount of
air via the automatic climate control so that
no vacuum is produced in the vehicle.▷It is not possible to start the engine and
operate the convertible top simultane‐
ously. When the engine is started using the
Start/Stop button or using the Auto Start/
Stop function, the convertible top move‐
ment is briefly interrupted.

Speed limit detection
The concept
Speed limit detection
Speed limit detection uses a symbol in the
shape of a traffic sign to display the currently
detected speed limit. The camera in the area of
the interior rearview mirror detects traffic signs
at the edge of the road as well as variable over‐
head sign posts. Traffic signs with extra sym‐
bols for wet road conditions, etc. are also de‐
tected and compared with the vehicle's
onboard data, such as for the rain sensor, and
will be displayed depending on the situation.
The system takes into account the information
stored in the navigation system and also dis‐
plays speed limits present on routes without
signs.
Hints Personal judgment
The system cannot serve as a substitute
for the driver's personal judgment of the traffic
situation.
The system assists the driver and does not re‐
place the human eye.◀
