Soft top
Important safety notes
GWARNING
If you do not fully open/close the soft top, the
soft-top hydraulics depressurize after a short
time. This causes the soft top to lower unex-
pectedly and may cause you or others to be
trapped. There is a risk of injury.
Always open or close the soft top completely.
!Never sit on the soft-top compartment
cover or stow heavy objects there. You will
otherwise damage the soft top and soft-top
compartment cover of the vehicle.
!When opening and closing the soft top,
make sure that:
Rthere is sufficient clearance above it, as the soft top swings upwards.
Rthe trunk is only loaded to below the trunk
partition.
Rthe trunk partition is not pushed up by the
load.
Rthe trunk lid is closed.
Rthere are no objects on the soft-top com-
partment cover
Rthe fabric is not dirty, wet or frozen. You could otherwise damage the soft top,
trunk and other parts of the vehicle.
Take the height of the vehicle into account when
opening and closing the soft top (
Ypage 334).
Make sure that the soft top is dry and clean
before opening it. Otherwise, water or dirt could
enter the vehicle interior or trunk.
You can open or close the soft top:
Rwhen the vehicle is stationary or
Rwhen you do not exceed a speed of 31 mph
(50 km/h) (Max. 35 mph (60 km/h), to avoid
interrupting the closing process while slightly
exceeding the speed limit).
If there is a strong head wind, it may not be pos-
sible to close the soft top fully. In this case,
reduce speed or stop in order to close the soft
top fully.
For safety reasons, Mercedes-Benz recom-
mends that you only open or close the soft top
when the vehicle is stationary.
If the soft top does not open or close fully, the
soft-top hydraulics are depressurized and the
soft top is lowered:
Rafter approximately 7 minutes when the igni-
tion is switched on
Rafter about 20 seconds if the ignition is
