Retractable hardtop
The retractable hardtop combines reliable
weather protection with simple and convenient
operation.
Please note:
>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 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., in tight parking spaces.
>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 luggage compart-
ment lid; otherwise, they could fall during move-
ments of the retractable hardtop and cause
damage or injury.
Driving when the hardtop is not fully opened or
not fully 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. opened and closed when the vehicle is
stationary. To avoid causing damage, do not
drive off until the hardtop has stopped
moving.<
Before opening and closing
Do not let the hardtop stop in an interme-
diate position when opening or closing.
Otherwise, there is the danger of personal injury
since the hardtop will be lowered automatically
after a few minutes.<
>Comply with the safety precautions
described above.
>Ensure that the luggage compartment lid is
closed.
>The vehicle should be parked on fairly level
ground. Excessive angle is indicated by
alamp.
>Fold down the cargo area partition and
make sure it engages, refer to the instruc-
tions below.
>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.

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 page48.
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
passenger side as a storage area. Make sure
that the passenger is sitting correctly, e.g.,
keeping his or her feet or legs in the footwell
and not on the dashboard; otherwise, leg inju-
ries can occur if the front airbag deploys.
Make sure that passengers do not lean their
heads against the side airbag; otherwise, seri-
ous injuries could result if the airbag 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 page85.
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 two 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 page44.
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 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.<
Note the information on safety belt damage
on page 45.

Closing
Make sure you hear the latch plate engage in
the belt buckle.
The upper belt anchor is suitable for adults of
any stature as long as the seat is adjusted prop-
erly, refer to page41.
Opening
1.Grasp the belt firmly.
2.Press the red button in the buckle.
3.Guide the belt into its reel.
'Fasten safety belts' reminder for driver
and passenger*
The indicator lamp comes on 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 'Fasten safety belts' reminder is issued as
long as the driver's safety belt has not been fas-
tened. In some country-specific versions, the
'Fasten safety belts' reminder is also activated
at road speeds above approx. 5 mph or 8 km/h if
the passenger safety belt is not fastened, if
objects are placed on the passenger seat, or if
driver or passenger 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.<
Mirrors
Exterior mirrors
The passenger's mirror is more convex
than the driver's mirror. The objects seen
in the mirror are closer than they appear. Do not
gauge your distance from traffic behind you on
the basis of what you see in the mirror; other-
wise, there is an increased risk of an accident.<

The setting for the exterior mirrors is stored for
the remote control currently in use
*. The stored
position is called up automatically when the
vehicle is unlocked.
Manual adjustment
The mirrors can also be adjusted manually:
press the edge of the glass.
Folding mirrors in and out*
At driving speeds up to approx. 12 mph/
20 km/h, you can fold the mirrors in and out by
pressing button2. This can be beneficial in nar-
row streets, for example, or for moving mirrors
that were folded in by hand back out into their
correct positions. Mirrors that were folded in are
folded out automatically at a speed of approx.
25 mph/40 km/h.
Before entering an automatic car wash,
fold in the exterior mirrors by hand or with
button2 to prevent them from being damaged
due to the width of the vehicle.<

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 on the passenger seat
Always transport children under the age
of 13 or smaller than 5 ft/150 cm in a child
restraint system suitable for their age, weight
and size, and with the passenger airbag deacti-
vated. Otherwise, there is an increased risk of
injury in the event of an accident or if the airbags
deploy.<
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.
For more information on automatic deactivation
of the passenger airbags refer to page86.
Installing child restraint
systems
After installing a child restraint system on
the passenger seat, make sure that the
front and side airbags for the passenger are
deactivated; otherwise, there is an increased
risk of injury if the airbags deploy.
Observe the child restraint system manufac-
turer's instructions when selecting, installing
and using child restraint systems. Otherwise,
the protective effect may be diminished.<
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 passenger seat
After installing a child restraint system on
the passenger seat, make sure that the
front and side airbags for the passenger are
deactivated; otherwise, there is an increased
risk of injury if the airbags deploy.<
Seat position
Before installing a child restraint system, move
the passenger seat as far back and up
* as pos-
sible to obtain the best possible position for
the belt.
Backrest width*
The backrest width of the passenger seat
must be at its widest possible setting. Do
not change the setting after installing the child
seat. Otherwise, the child seat's stability on the
passenger seat is limited.<
1.Adjust the backrest width to its widest set-
ting, refer to page43.
2.Install the child seat.
Child seat security
The safety belt for the passenger can be locked
to prevent it from being pulled out when it is
used to secure child restraint systems.
