Retractable hardtop
Opening and closing the retractable hardtop
For safety reasons, the retractable hardtop
can only be opened and closed when the
vehicle is standing still.Warning!
G
To prevent possible accidents, only drive the
vehicle with the retractable hardtop either
completely closed and locked, or fully low-
ered into its storage compartment.
If the retractable hardtop does not com-
pletely open or close, the roof hydraulics will
lose pressure and the retractable hardtop is
lowered

after approximately 7 minutes when the
ignition is switched on


after approximately 15 seconds when
the ignition is switched off
Shortly before the retractable hardtop is
lowered, a warning will sound and in the left
multifunction display you will see K, in
the right multifunction display you will see
the message
being lowered
.
Lock the retractable hardtop again before
driving any further (
page 202). Otherwise,
the unlocked hardtop could open while the
vehicle is in motion and cause you to lose
control of the vehicle. You or others could
be injured as a result.
Warning!
G
Before operating the retractable hardtop
switch, make sure there is no danger of any-
one being injured by the moving parts (re-
tractable roof, roof frame, and trunk lid) due
to inattention.

frame, upper windshield area, hardtop, shelf
behind roll bars, or trunk lid while the re-
tractable hardtop is being raised or lowered.
Serious personal injury may occur.
If potential danger exists, release the re-
tractable hardtop switch. This immediately
interrupts the raising or lowering procedure.
