Opening and closing
When the vehicle is stationary and at radio
readiness or beyond, refer to page50:
If possible, conserve the battery by only
operating the retractable hardtop when
the engine is running.
Before closing the retractable hardtop, remove
all foreign objects from the windshield frame as
these could prevent the hardtop from closing
properly.<

hardtop is opened or closed. Convenient
closing
* If you continue pressing the buttons
after the LED 3 goes out, the windows move
back up.<
If the windows pause briefly as they move, this
is for technical reasons and is not a malfunction.
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
green LED lights up. It goes out as soon as
the top is fully opened or closed.
>If the red LED flashes when you release the
switch, the opening or closing action has
not yet finished.>If the red LED lights up when the switch is
pressed, the cargo area 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.
Open or close the hardtop fully; other-
wise, there is a risk of injury or damage
when driving.
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 and31.
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.

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 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.

Lumbar support*
You can also adjust the contour of the backrest
to obtain additional support in the lumbar

nations of driver's-seat and exterior-mirror
positions.

for the remote control currently in use.
You can select whether the seat should be reset
to that position.
When this Personal Profile function is
used, first make sure that the footwell
behind the driver's seat is free of obstacles.
Failure to do so could result in damage to the
objects if the seat were to move rearward.<
The adjusting procedure is halted immediately
when you touch a seat adjustment switch or
one of the memory buttons.

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.

'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 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.<

mirror and windshield, and do not affix adhesive
labels or stickers of any kind to the windshield
directly in front of the mirror.
