Soft top emergency operation
If the soft top cannot be automatically
closed, check the following:
Is the luggage cover engaged in place
(page 262)?
Have the roll bars been released? If so,
lower the roll bars manually
(page 424).
Is the trunk lid closed (
page 110)?
Is there sufficient on-board voltage?
Start the engine if necessary.
These messages will also appear in the
multifunction display (

If automatic operation still does not func-
tion properly, you can close the soft top
manually.
This procedure should be performed with
great care by two persons.
!Manually closing the soft top is a com-
plicated and technically demanding
procedure. Close the soft top manually
in emergency cases only. Otherwise,
visit an authorized Mercedes-Benz
Center. Please read the instructions
fully before beginning operation and
only undertake it with another person
and if you feel fully capable of perform-
ing the tasks involved. Warning!

helps you. Otherwise, you could become
trapped or injured.
Remove any wristwatches or jewelry
such as rings or bracelets. Otherwise,
they could get caught in the vehicle
mechanism, causing personal injury to
yourself or damage to the vehicle.
Always use the grips provided as indi-
cated. Otherwise you could injure your-
