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
area.
>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 trunk lid,
and in particular do not attach magnetic
racks.
>When the retractable hardtop is operated,
the trunk lid swings back and up. Before
operating the retractable hardtop, ensure
that there is enough clearance, 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 area. If necessary, remove items
from the cargo area beforehand to avoid
water stains or soiling.
Do not place any objects on the retract-
able hardtop or on the trunk lid; other-
wise, they could fall during movements 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 during the
opening or closing procedure. 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 area partition is
folded down and engaged on both sides,
refer to page110; otherwise, it will not be
possible to open the retractable hardtop.
>Do not place any objects next to or on the
cargo area partition and close the storage
compartment on the left side of the cargo
area.
>Do not exceed the maximum loading height
under the cargo area partition; refer to the
label in the cargo area showing a line indi-
cating the maximum height.
>Ensure that the trunk lid is closed.
>The vehicle should be parked on fairly level
ground. Excessive angle is indicated by a
lamp.

closed, the trunk lid cannot be opened
and the windows cannot be moved.<
Convenient operation with remote
control or via door lock
Refer to pages28 and30.
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 area. Brief instructions for
operation can be found on the protective cover.
1.Remove the wind deflector from the protec-
tive cover and unfold it, arrows1.

Adjustments
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 page52.
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 should come between the
airbags 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 deploys.
Make sure that passengers keep their heads
away from the side airbag and do not lean
against the cover of the head airbag; otherwise,
serious injuries can result if the airbag
deploys.<
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 page90.
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 page44.
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 page48.
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

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
danger in the event of an accident of sliding
under the safety belt, eliminating the protection
normally provided by the belt.<
Comply with the instructions on head restraint
height on page44, and on damaged safety
belts on page49.

"Fasten safety belts" reminder for
driver's and front passenger seat
The indicator lamps light up and an
acoustic signal sounds. In addition, a
message appears on the Control Dis-
play. Check whether the safety belt
has been fastened correctly.
The "Fa sten safety belts " reminder is iss ued a s
long as the driver's safety belt has not been fas-
tened. The "Fasten safety belts" reminder is
also activated at road speeds above approx.
5 mph or 8 km/h if the front passenger safety
belt is not fastened, if objects are placed on the
front passenger seat, or if driver or front pas-
senger unfasten their safety belts.
Damage to safety belts
If the safety belts are damaged or
stressed in an accident: have the belt sys-
tem, including any belt tensioners or child
restraint systems, replaced and the belt
anchors checked. Have this work done only by
your BMW center or at a workshop that works
according to BMW repair procedures with cor-respondingly trained personnel. Otherwise, it is
not guaranteed that the safety devices will func-
tion properly.<
Coupe: belt hand-over
The concept
The belt hand-over makes it easier for you to
fasten your safety belt. When you close the
door and switch on radio readiness or the igni-
tion, the belt hand-over extends automatically
and presents the in a position that is convenient
for fastening it around you. After you have fas-
tened your safety belt, the belt hand-over
retracts to its original position.
Even if you have not yet fastened your safety
belt, the belt hand-over will retract if you:
>Wait for more than approx. one minute
>Open the corresponding door
>Start driving.
Closing the respective door reactivates the belt
hand-over if the ignition or radio readiness is on.
Front passenger seat
The belt hand-over will extend only if the seat is
occupied and after the front passenger door is
closed.
Pinch protection system
If the belt hand-over encounters resistance on
moving in or out, it moves back slightly in the
opposite direction and stops in this position. To
reactivate the belt hand-over: open and close
the door or switch the ignition off and on.
Although there is a pinch protection sys-
tem, always check that the maneuvering

Transporting children safely
The right place for children
Do not leave children unattended in the
vehicle; otherwise, they could endanger
themselves and/or other persons by opening
the doors, for example.<
Children always in the rear
Accident research has shown that the safest
place for children is on the rear seat.
Children under the age of 13 or smaller
than 5 ft/150 cm may be transported only
in the rear in suitable child restraint systems
appropriate for their age, weight and size. Oth-
erwise, there is an increased risk of injury in the
event of an accident.<
Children 13 years of age or older must be buck-
led in with a safety belt as soon as there no
longer is any child restraint system that is
appropriate for their age, size and weight.
Exception for front passenger seat
Should it be necessary to use a child
restraint system on the front passenger
seat, the front and side airbags for the front pas-
senger must be deactivated. Otherwise, a child
traveling on that seat will face a significant risk
of injury if the airbags are triggered off, even
with a child restraint system.<
For more information on automatic deactivation
of the front passenger airbags refer to page90.
Installing child restraint
systems
Observe the child restraint system manu-
facturer's instructions when selecting,
installing and using child restraint systems.
Otherwise, the protective effect may be dimin-
ished. <
Standard child restraint systems are designed
to be secured with a lap belt or with the lap-belt
section of a lap-and-shoulder belt. Incorrectly or improperly installed child restraint systems
can increase the risk of injury to children.
Always follow the installation instructions for
the system with the greatest care.
On the front passenger seat
After installing a child restraint system on
the front passenger seat, make sure that
the front and side airbags for the front passen-
ger are deactivated; otherwise, there is an
increased risk of injury if the airbags deploy.<
Seat position
Before installing a child restraint system, move
the front passenger seat as far back and up as
possible to obtain the best possible position for
the belt. Do not change the seat position after
this.
Backrest width*
The backrest width of the front passenger
seat must be at its widest possible set-
ting. Do not change the setting after installing
the child seat. Otherwise, the child seat's stabil-
ity on the front passenger seat is limited.<
1.Adjust the backrest width to its widest set-
ting, refer to page44.
2.Install the child seat.
Child seat security
The rear safety belts and the front passenger
safety belt can be prevented from being pulled
out in order to fasten child restraint systems.
