Lowering the storag e bay bas e
-Move the lever to pos ition @ to lower the var iab le
storage bay=> fig. 56 .
The storage bay bottom can only be lifted when the top i s clos ed
and NOT folded up in side the ba y.
This creates more space in the
luggage compartment . The storage bay base must be in the lowered
position before the top can be lowered.
When the top
o pe ns it folds down completely into the storage bay
des igned to contain it. Only with the storage bay expanded is it
poss ible to open the top . This feature prevents the top from forcing
i t s way down agains t objects blocking its storage space . For this
reason your vehicle has less luggage capacity when the top is down
than when it is up and closed . It is not possible to lift the base of the
storage bay when it contains the folded down top .•
Messages in the instrument cluster display
If the power top fails to activa te when you operate the
control switch, a message will appear in the display to
indicate what is wrong.
Before the power top can start to open or close automatically, a
number of conditions must be met . The systems checks, for
instance, if the storage bay has been expanded before the power
top opens.
The instrument c luster disp lay will generate a message if one of
these condi tions does not check right or if a malfunction occurs .
Power top: ple ase clo se rear lid
The lid on the trunk must always be closed when opening or closing
t he power top . This message will appear in the display if the trunk
lid is not closed .
Power top: pl ease low er stor age ba y
The variable storage bay must be in the lowered (expanded) posi ­
tion before the power top can be opened=> page 64 . This message
will appear in the display if the variable storage bay is not in the lowered position (lever to the right) when opening the power top. ..,

Power top: ca nnot b e use d
Power top not operating
This message wi ll appear in the display if the power top has been
deactivated for safety reasons or if there is a malfunction. Possible
causes are:
• vehicle speed t oo high: the power top operation is deactivated
for safety reasons if the vehic le is mov ing at a speed above 3 mph
(5 km/hi.
• battery voltage too low: the power top wil l not operate if the
battery voltage is too low . This is a precautionary feature to make
s u re that the re is always enough battery power avai lable to start the
engine. The power top can be activated again once the engine has
been started and is running.
• ove rload cut -off: if the power top is operated repeatedly the
hydraulic actuator components will be severely stressed . In this
case the over load cut -off will safeguard the system against damage.
This safeguard deactiva tes the system fo r abou t 15 to 30 minutes.
After this time the power top can be operated again as usual=> & .
• Malfunction: One possible cause of a malfunction is the fai lure
of a system component. In this case the power top can a lso be
manual ly operated =>
page 68. Turning off the ignition during the
opening or closing process may cause a malfunction. You can
correct this yourself=>

Wind deflector
Applies to veh icles: with wind def lector
General notes
The wind deflector reduces turbulent airflow inside the
vehicle for greater comfort when driving with the power top open.
The optional wind deflector is stored in a bag in the luggage
compartment. To prevent damage it should always be kept in this
bag when not installed. Do not place heavy objects (e.g. crates or
heavy shopping bags) on top of the wind deflector.
& WARNING
• The two rear seats must not be occupied when the wind
deflector is installed.
• Do not place any objects on the horizontal surface of the wind
deflector. The deflector is not designed to support loads. Be also
aware that objects left there could be blown off by the airstream
when the vehicle is moving. -Risk of injury!
0 Note
When you adjust the front seats when the wind deflector is
installed, be careful not to push the backrests into the wind
deflector when reclining the seats or when moving them back. This
can damage the deflector, especially the locking mechanism. •

the rear seatbench and lift the power top up by grabbing it at the
center. •
