After switching off the ignition
When the remote control is removed or the igni-
tion is switched off, you can still operate the
windows for approx. 1 minute as long as no
door has been opened.
Convenient operation
For information on convenient operation via the
remote control or the door lock, refer to page29
or32. For information on closing with conve-
nient access, refer to Locking on page36.
Pinch protection system
If the closing force exceeds a specific value as a
power window closes, the closing action is
interrupted and the window reopens slightly.
Despite the pinch protection system
check and clear the window's travel path
prior to closing it, otherwise the safety system
might fail to detect certain kinds of obstruc-
tions, such as thin objects, and the window
would continue closing.
Do not install any accessories that might inter-
fere with window movement. Otherwise the
pinch protection system could be impaired.
Convertible: the rear windows are not equipped
with pinch protection. Therefore, watch them
closely when closing to avoid personal injury.<
Closing without pinch protection
If there is an external danger, or if ice on the win-
dows, etc., prevents you from closing the win-
dows normally, proceed as follows:
1.Pull the switch past the resistance point and
hold it there. Pinch protection is limited and
the window reopens slightly if the closing
force exceeds a certain value.
2.Pull the switch again past the resistance
point within approx. 4 seconds and hold it
there. The window closes without pinch
protection.

tion is switched off, you can still operate the roof

Opening and closing
40 for approx. 1 minute as long as no door has
been opened.
Pinch protection system
If the glass roof encounters an obstruction dur-
ing closing from approximately the middle of
the opening in the roof, or during closing from
the raised position, the closing movement is
interrupted and the glass roof is opened again
slightly.
Despite the pinch protection system
check and clear the roof's travel path prior

The following tips will enhance your driving
pleasure in your convertible:
>It is advisable that you close the convertible
top when you park the vehicle. Not only
does the closed top protect the vehicle inte-
rior against unanticipated weather damage,
it also offers a certain amount of theft pro-
tection. However, even when the top is
closed, valuables should only be stored in
the locked cargo bay.
>Do not attach roof-mounted luggage sys-
tems to the convertible top.
>When opening a wet top, e.g. after driving in
the rain, water may drip into the cargo bay. If
necessary, remove items from the cargo
bay beforehand to avoid water stains or soil-
ing.
At temperatures below +147/–106, do
not move the convertible top or damage
may occur.
Do not keep the convertible top in the convert-
ible top box for longer than one day if it is wet,
otherwise the moisture may cause damage.
Do not place objects on the convertible top, as
otherwise they may fall off when you operate
the convertible top and cause damage or injury.
Never move the convertible top when the roll-
over protection system is in the activated posi-
tion.
Always fully complete a convertible top move-
ment. Driving with the convertible top incom-
pletely opened or closed can result in damage
or injury.
Do not reach into the mechanism during the
opening or closing procedure. Keep children
away from the opening/closing path of the con-
vertible top.
For safety reasons, only move the convertible
top when the vehicle is stationary, if possible.<
The convertible top swings upward when
opening and closing. When operating the
convertible top in a garage, under a bridge, etc.,
ensure that there are at least 6 ft 7 in/2 m of
headroom, otherwise the vehicle may be dam-
aged. >Comply with the safety precautions
described above.
>Ensure that the cargo bay partition is folded
down and engaged on both sides, refer to
page109, otherwise it will not be possible
to open the convertible top.
>Ensure that the cargo does not press
against the cargo bay partition from below.
>Ensure that the luggage compartment lid is
closed.

The side windows move down slightly
when the buttons for convertible top
operation are pressed.<
Operation while driving
You can open or close the convertible top while
driving, as long as the car is not moving faster
than approx. 25 mph/40 km/h.

Opening and closing
42 If you accelerate to over 30 mph/50 km/h while
the convertible top is moving, the procedure is
interrupted.
When operating the convertible top while
driving, pay extra attention to the traffic to
avoid an accident. If possible, do not move the
convertible top while driving in reverse gear,
because your view to the rear is severely limited
during the procedure. Do not operate the con-
vertible top while driving in windy conditions.
Do not drive faster than 30 mph/50 km/h, other-
wise damage to the vehicle can occur.<

the left LED lights up green. It goes out as
soon as the top is fully opened or closed.
In the following situations, a message appears
on the Control Display or an acoustic signal
sounds in addition to the LED lighting up:
>If the right-hand LED flashes red when you
release the button, the opening or closing
action has not yet finished.
>If the right-hand LED lights up red when the
button is pressed, the cargo bay partition is
raised, the luggage compartment lid is not
closed or there is a malfunction. The con-
vertible top cannot be moved.
Interruption
The automatic sequence of movements is
interrupted if the button for the convertible top
operation is released. The sequence can be
continued in the desired direction by pushing or
pulling the buttons.
If the opening or closing procedure is inter-
rupted for an extended period, the convertible
top remains in the raised position for approx.
10 minutes and then slowly moves to a stable
position.
A convertible top that is not fully opened
or closed is a safety hazard.<

Sitting safely
The ideal sitting position can make a vital con-
tribution to relaxed, fatigue-free driving. In con-
junction with the safety belts, the head
restraints and the airbags, the seated position
has a major influence on your safety in the event
of an accident. To ensure that the safety sys-
tems operate with optimal efficiency, we
strongly urge you to observe the instructions
contained in the following section.
For additional information on transporting chil-
dren safely, refer to page55.
Airbags
Always maintain an adequate distance
between yourself and the airbags. Always
grip the steering wheel on the rim, with your
hands in the 3 o'clock and 9 o'clock positions,
to minimize the risk of injury to the hands or
arms in the event of the airbag being triggered
off.
No one and nothing is to come between the air-
bags and the seat occupant.
Do not use the cover of the front airbag on the
front passenger side as a storage area. Make
sure that the front passenger is sitting correctly,
i.e. not resting feet or legs on the dashboard,
otherwise leg injuries can occur if the front air-
bag is triggered.
Make sure that passengers do not lean their
heads against the side or head airbag, other-
wise serious injuries could result if the airbags
suddenly deployed.<
Even if you follow all the instructions, injuries
resulting from contact with airbags cannot be
fully excluded, depending on the circum-
stances. The ignition and inflation noise may
provoke a mild hearing loss in extremely sensi-
tive individuals. This effect is usually only tem-
porary.
For airbag locations and additional information
on airbags, refer to page89.
Head restraint
A correctly adjusted head restraint reduces the
risk of neck injury in the event of an accident.
Adjust the head restraint in such a way
that its center is at approx. ear level. Oth-
erwise, there is an increased risk of injury in the
event of an accident.<
Head restraints, refer to page47.
Safety belt
Before every drive, make sure that all occupants
wear their safety belts. Airbags complement the
safety belt as an additional safety device, but
they do not represent a substitute.
Your vehicle has four seats, each of which is
equipped with a safety belt.
Never allow more than one person to
wear a single safety belt. Never allow
infants or small children to ride in a passenger's
lap. Make sure that the belt in the lap area sits
low across the hips and does not press against
the abdomen.
The safety belt must not rest against the throat,
run across sharp edges, pass over hard or frag-
ile objects or be pinched. Fasten the safety belt
so that it sits as snugly as possible against the
lap and shoulder without being twisted. Other-
wise the belt could slide over your hips and
injure your abdomen in the event of a frontal
collision. Avoid wearing bulky clothing and reg-
ularly pull the belt in the upper-body area taut,
otherwise its restraining effect could be
impaired.<
Safety belts, refer to page51.
Seats
Note before adjusting
Never attempt to adjust your seat while
the vehicle is moving. The seat could
respond with unexpected movement, and the
ensuing loss of vehicle control could lead to an

46 accident.
On the front passenger seat as well, do not
incline the backrest too far to the rear while the
vehicle is being driven, otherwise there is a dan-
ger in the event of an accident of sliding under
the safety belt, eliminating the protection nor-
mally provided by the belt.<
Comply with the instructions on head restraint
height on page47, and on damaged safety
belts on page51.
