tions, the symbols appear one after the other for about two
seconds.

& WARNING
• When you lock your vehicle from outside, nobody -especially
children · should remain inside the vehicle. Remember, when you
lock the vehicle from the outside the windows cannot be opened
from the inside.
• When you leave the vehicle, always remove the ignition key and
take it with you. This will prevent passengers (children, for example) from accidentally being locked in the vehicle should they
accidentally press the power locking switch.
• Do not leave children inside the vehicle unsupervised. In an
emergency it would be impossible to open the doors from the
outside without the key.
[ i J Tips
• In the event of a crash with airbag deployment all locked doors
will be automatically unlocked to give access to the vehicle occu ­
pants from the outside .
• If the power locking system should malfunction, you can lock
each door individually using the vehicle key.
• If the power locking system should fail, you can still open the
fuel tank flap in an emergency=>
page 218.
• You are well advised not to keep valuables inside an unattended
vehicle, visible or not . Even a properly locked vehicle cannot provide
the security of a safe! •

Folding top
Folding top
Folding top
General
The comprehensively engineered design of the fabric folding top
allows it to be operated quickly and simply. When open, the folding
top is stowed completely in a tonneau provided specifically for this
purpose.
In normal operating conditions, the folding top is wind -and water ­
proof. Under certain circumstances, a small quantity of droplets might form, but only in extremely inclement weather, e.g. torrential
or continuous heavy rain. This is normal and not a cause for
concern .
Follow the care instructions =>
page 203, "Folding top care" to main ­
tain the folding top's attractive appearance and to keep it wind- and
waterproof. Please follow these instructions as well:
• Stow and open the folding top only when it is clean . When the
top is folded away, sharp -edged contaminants can build up as silt
and cause wear spots on the rear window, which may damage the
folding top over time. Of course, ice and snow should also be
removed before opening the folding top.
• Under no circumstances should you use sharp -edged or abrasive
objects to remove ice and snow. Use a commercial ice scraper to
remove ice from of the rear window.
• The folding top should be opened only if it is completely dry . If
the folding top is opened and then stored wet, unattractive indenta ­
tions may develop. In addition, over time, mold and mildew stains
can develop.
• Do not leave the folding top open for several weeks at a time;
instead, open and close it from time to time so that the fabric does
not discolor where it folds, and to prevent creases from forming. This is especially
important if it happens to be stowed while still
damp on occasion.
• Because the fabric becomes less flexible when temperatures
drops below zero, we recommend not operating the folding top
below0°C.
& WARNING
• When operating the folding top, make sure that any external
factors {e.g. the wind) do not impair its function or endanger other
drivers.
• Never drive while the folding top is not properly secured. Other­
wise, it may be pulled open by the wind. This can cause injuries
and damage to the vehicle -danger of an accident!
• When opening and closing the folding top make sure to keep
yourself and others clear of all moving parts. Risk of injury!
0 Note
• Always make sure that there is enough clearance above the
vehicle so that the folding top is not damaged when opening and
closing.
• Do not place any objects in the tonneau to avoid damage when
opening the folding top.
[ i] Tips
• The folding top should be operated only with the ignition
switched on.
• When parking the car with the folding top open, bear in mind
that the vehicle's interior is not protected from damage due to unex­ pected weather conditions, or unauthorized access. It is therefore
advisable to close the folding top before leaving the vehicle. If

& WARNING
When opening and closing the power top make sure to keep your­
self and others clear of all moving parts. Risk of injury! •

Emergency Operation of the Folding
Top
A pp lies to vehicles: wit h p owe r fo ld ing t op
General information
The folding top can be closed manually if it malfunctions.
- Set the parking brake.
- Open the windows.
- Remove the key from the ignition.
Close the folding top manually only in an emergency situation . The
best way course of act ion is to contact your dealership to have the
cause of the malfunction corrected. .,

The folding top's emergency operation basically consists of the
following steps:
• Depressurize the hydraulic system for operating the folding top:
The hydraulic system pump must be depressurized.
• Unlock the covers : The covers must be manually unlocked and
positioned.
• Raise the folding top: The folding top must be manually lifted out
of its well and raised.
• Lock the folding top: The latches for the folding top must be
locked with the emergency lock key.
• Close the hydraulic system's emergency operation bolt: Turn the
emergency operation bolt=> fig. 54 to the right to close the
hydraulic system that operates the folding top.
& WARNING
• When raising the folding top, take care not to reach into the
linkage that operates the folding top or any of its other moving
parts. Otherwise, your hands may be trapped in the mechanism -
risk of injury!
• Never drive while the folding top is not properly secured . Other­
wise, it may be pulled open by the wind. This can cause injuries and damage to the vehicle -danger of an accident!
[ i] Tips
Get a second person help you to close the folding top. It is much
easier to raise the folding top with the help of a second person. •
