Pinch protection system
If the closing force exceeds a specific value as a
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
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
to closing it, otherwise the safety system might
fail to detect certain kinds of obstructions, such
as very thin objects, and the roof would con-
tinue closing.<
Closing without pinch protection
If there is an external danger, press the switch
forward past the resistance point. The roof
closes without pinch protection.
Following interruptions in electrical
power supply
After a power failure, there is a possibility that
the glass roof can only be raised. The system
must be initialized. BMW recommends having
this work done by your BMW center.

Convertible: retractable
hardtop
The retractable hardtop combines reliable
weather protection with simple and convenient
operation.
The following tips will enhance your driving
pleasure in your convertible:
>It is advisable that you close the retractable
hardtop when you park the vehicle. Not only
does the closed hardtop protect the vehicle
interior against unanticipated weather dam-
age, it also offers theft protection. However,
even when the hardtop is closed, valuables
should only be stored in the locked cargo
bay.
>Do not attach roof rack systems to the
retractable hardtop, and in particular do not
attach magnetic racks.
>Do not attach rack systems to the luggage
compartment lid, and in particular do not
attach magnetic racks.
>When the retractable hardtop is operated,
the luggage compartment lid swings back
and up. Before operating the retractable
hardtop, ensure that there is enough clear-
ance, e.g. when parked in front of a wall.
>If you open the hardtop while it is wet, 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 soiling.
Do not place any objects on the retract-
able hardtop or on the luggage compart-
ment lid, otherwise they could fall during move-
ments of the retractable hardtop and cause
damage or injury.
Never move the retractable hardtop when the
rollover protection system is in the activated
position.
Driving when the hardtop is not fully opened or
closed may result in damage or injury.
Do not reach into the mechanism while the
hardtop is opening or closing. Keep children
away from the swiveling area of the retractable
hardtop.<
The retractable hardtop cannot be moved
at temperatures below + 147/–106. A
message appears on the Control Display.<
The retractable hardtop can only be
opened and closed when the vehicle is
stationary. To avoid causing damage, do not
drive off until the hardtop has stopped mov-
ing.<
Before opening and closing
>Comply with the safety precautions
described above.
>Ensure that the cargo bay partition is folded
down and engaged on both sides, refer to
page117, otherwise it will not be possible
to open the retractable hardtop.
>Do not place any objects next to or on the
cargo bay partition and close the storage
compartment on the left side of the cargo
bay.
>Do not exceed the maximum loading height
under the cargo bay partition; refer to the
label in the cargo bay showing a line indicat-
ing the maximum height.
>Ensure that the luggage compartment lid is
closed.
>The vehicle should be parked on fairly level
ground. Excessive angle is indicated by a
lamp.

The side windows move down slightly
when the switch for hardtop operation is
pulled or pushed.<
If you push or pull the switch for a longer period
after the LED2 goes out, the windows move up
again.<
LEDs
In the following situations, a message appears
on the Control Display or an acoustic signal
sounds in addition to the LED lighting up:
>While the hardtop is being operated, the left
LED lights up green. It goes out as soon as
the top is fully opened or closed.
>If the right-hand LED flashes red when you
release the switch, the opening or closing
action has not yet finished.
>If the right LED lights up red when the
switch is pressed, the cargo bay partition is
folded up, the luggage compartment lid is
not closed, the vehicle is standing on a
strong incline or there is a malfunction. The
retractable hardtop cannot be moved.
Interruption
The automatic sequence of movements is
interrupted if the switch for hardtop operation is
released. The sequence can be continued in
the desired direction by pushing or pulling the
switch.
A hardtop that is not fully opened or
closed is a safety hazard.
Do not interrupt and resume the closing proce-
dure several times in close succession as this
could damage the mechanism.<
If the hardtop is not fully opened or
closed, the luggage compartment lid can-
not be opened and the windows cannot be
moved.<
Convenient operation with remote
control or via door lock
Refer to pages30 and32.
Wind deflector*
The wind deflector keeps air movements in the
passenger compartment to a minimum when
the hardtop is open and provides an even more
comfortable ride, particularly at high speeds.
Installation
The wind deflector is stored in a protective
cover in the cargo bay. Brief instructions for
operation can be found on the protective cover.
1.Remove the wind deflector from the protec-
tive cover and unfold it, arrows 1.

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 page56.
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,
e.g. 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 airbags, 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 page97.
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 regularly 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.
Manual adjustment
Observe the adjustment instructions on
page45 to ensure the best possible per-
sonal protection.<
