switched offAfter the ignition has been switched off:
You can still use the electric power win-
dows for up to 15 minutes, as long as

Convertible topThe completely automatically operated
convertible top combines assured pro-
tection against the elements together
with simple and easy handling.
So that you will get the most out of
enjoying your convertible, here are a
few tips:
>It is advisable to close the convertible
top when the vehicle is being parked.
The closed convertible top not only
protects the passenger compartment
from unforeseeable damage from the
weather, it also provides a certain
degree of theft protection. In addi-
tion, keep valuables only in the
locked luggage compartment, even
with the convertible top closed
>Never mount a roof-mounted luggage
rack on the convertible top
>At temperatures below 147/–106
do not operate the convertible top to
prevent damage.
Never store the convertible top
while it is wet to avoid permanent
damage from moisture.<

Driving with the opening or clos-
ing operation not completely
ended can lead to damage and/or inju-
ries.
Traffic laws applicable in your area take
precedence when you operate the con-
vertible top, otherwise you may be
breaking the law.
Do not lay objects on the convertible
top, since they would fall off when the
convertible top is operated and cause
damage or injuries.
Do not reach into the convertible top
mechanism during opening and closing.
Keep children away from the moving
parts of the convertible top during
operation.<
If possible, only operate the con-
vertible top with the vehicle
stopped, as otherwise the process may
be interrupted.
If you set the convertible top in motion
with the vehicle stationary and then
have to start suddenly – for instance, at
a traffic light – you can still complete
the operation by driving as slowly as
possible and again pressing and main-
taining pressure on the button.
Before closing the convertible top,
remove any objects from the windshield
frame that could keep the convertible
top from closing properly.<
To close the electric power win-
dows while driving, always be
sure to first close either the rear win-
dows, or all 4 windows at the same
time, otherwise, at high speed, the win-
dows may not close tightly.<
At higher speeds, the ensuing
vacuum in the passenger com-
partment can cause the convertible top
to begin fluttering. Increase the air sup-
ply via the ventilation controls so that a
vacuum does not occur in the vehicle.<

vertible top if the engine is running. This
saves unnecessary battery wear.
1. Read and comply with the preceding
safety precautions
2. Before opening the convertible top,
make sure that the convertible top

4. Press and hold the corresponding
button for convertible top operation.
The red indicator lamp will light up
while the convertible top is in motion.
It goes out as soon as the opening or
closing operation has been com-
pleted.
If the red indicator lamp flashes after
the button is released, then the
opening or closing operation is not
yet completed. The sequence can be
continued in the desired direction by
pressing this button.
If the yellow indicator lamp lights up
continuously with the button
pressed, then the convertible top
compartment panel is raised and the
convertible top cannot be moved,
refer to step 2.
The automatic sequence will be
interrupted immediately if you
release the button that operates the
top. The sequence can be continued in
the desired direction by pressing this
button.<
During convertible top operation
the rear window moves toward the
passenger compartment. To prevent
injuries, make sure that the closing path
of the convertible top is unobstructed.<
When operating the convertible top, the
windows will lower slightly when you
press the button, and after the opening
or closing operation has finished, they
will go back up, if you keep holding the
button down for more than 2 seconds
after the indicator lamp has gone out.
The luggage compartment lid cannot be
opened while the convertible top is in
motion.
Do not close the side power win-
dows using the buttons if the con-
vertible top operation has been inter-
rupted.<
If the convertible top has been
stored in the convertible top com-
partment for longer periods, e.g. during
the winter months while the hardtop is
being used, it may be necessary to
manually support the first automatic
closing operation: if the convertible top
should halt right before the closing
phase is completed, press against the
front part of the convertible top frame
from the outside to help the closing
process along. Keep pressing the but-
ton while doing so until the top starts
up again on its own.<
Operate the convertible top manu-
ally in emergency situations only
to avoid causing damage due to incor-
rect operation.<
If the opening or closing operation
is interrupted, the convertible top
remains in the respective position for
15 minutes, and the sequence can be
continued in the desired direction with
the button. After that, the convertible
top can be moved again and, if it is an
emergency situation, you may have to
help the top along manually. This can
also be done in ignition key position 0.
In certain cases, the luggage compart-
ment lid cannot be opened if the open-
ing or closing operation has been inter-
rupted.<

3Recess
Only actuate the convertible top
manually to close it, however
never to open it, as the convertible top
compartment lid cannot be locked and
would open during driving.<
Manual closing is best carried out
with two persons from outside
with the driver's door open and the
driver's seat folded forward. No one is
to be in the rear seat while you are
doing this.<
1. Remove the center piece between
the rear seats. Take the trim off of the
guide rod and flip it forward. Press
down hard on the emergency lock 1
– see arrow. After a brief pause, the
mechanisms for the convertible top
compartment lid will be unlocked
If the mechanisms for the convert-
ible top compartment lid do not
unlock, then insert the Allen wrench 2
into the recess 3 and turn clockwise
until the mechanisms unlock.<
2. If the luggage compartment lid is
closed, open the convertible top
compartment lid up as far as the stop
will allow
3. Grasp the convertible top by the lat-
eral guide section – see arrow 1 –
and the front convertible top frame –
see arrow 2. Lift out the top and
swing forward until you encounter a
perceptible resistance at a stop.

Wind deflector*With the convertible top open, the wind
deflector keeps air movement in the
passenger compartment to a minimum,
thus providing you with a pleasant
drive, even at higher speeds. The wind
deflector comes in a protective sleeve,
and because of its slim dimensions, can
be easily stored in the luggage com-
partment.Installation1. Remove wind deflector from the pro-
tective sleeve
2. Flip out both sides and lock into
place. It is essential for the two com-
ponents marked in the illustration –
see arrows – to mesh at this point
3. Hold the wind deflector so that the
smaller half points toward the front
and guide the mounting pin for the
side piece into the proper opening
4. Pull back on the mounting pin for the
other side piece by using a slide, so
that the mounting pin can be guided
into the opening provided

ment lid via the convertible top con-
trol button, refer to page 42, and
open the convertible top compart-
ment lid

48To adjust
Safe seating positionFor relaxed and fatigue-free driving you
should select a sitting position that
reflects your personal requirements. In
combination with the safety belts and
airbags, the correct seating position
plays an important role in enhancing
occupant safety in the event of an acci-
dent. To ensure that the vehicle's safety
systems provide you with optimal pro-
tection, we request that you direct your
careful attention to the following sec-
tion.
For supplementary information on
transporting children, refer to page 59.Sitting safely with airbags
Always maintain an adequate dis-
tance between yourself and the
airbags. Always hold the steering wheel
by the rim to keep any chance of injury
to hands or arms to an absolute mini-
mum should the airbag be deployed.
Never allow any objects, individuals or
animals to obstruct the areas between
passengers and airbags. Never use the
front airbag's cover as a storage tray or
support for objects of any kind. Never
allow front passengers to rest their feet
or legs on the airbag cover.<
For airbag locations and additional
information on airbags, refer to
page 57.Sitting safely with safety belts
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. Avoid twisting the
belt while routing it firmly across the
pelvis and shoulder, wear it as snugly
against your body as possible. Do not
allow the belt to rest against hard or
fragile objects in your pockets. Do not
route the belt across your neck, or run it
across sharp edges. Be sure that the
belt does not become caught or
jammed. Avoid wearing bulky clothing
and pull on the lap belt periodically to
retension it over your shoulders. In the
event of a frontal impact, a loose lap
belt could slide over the hips, leading to
abdominal injury. In addition, the safety
belt's restraint effectiveness is reduced
if the belt is worn loosely. Expectant
mothers should always wear their
safety belts, taking care to position the
lap belt against the lower hips, where it
will not exert pressure against the
abdominal area.<
For information on using the safety
belts, refer to page 52.

SeatsWhen adjusting your seat, always
observe the following precautions
Never try to adjust your seat while
operating the vehicle. The seat
could respond with an unexpected
movement, and the ensuing loss of
vehicle control could lead to an acci-
dent. Never ride with the backrest
reclined to an extreme horizontal angle
– important for front passengers to
remember. Keep the backrest relatively
upright to minimize the risk of sliding
under the safety belt and sustaining
injury in an accident.
With the wind deflector in place: never
push the front seats all the way back to
avoid damaging the wind deflector.<
