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 tilted. The system
must be initialized. BMW recommends having
this work performed 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 trunk.
> 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 trunk. If necessary, remove items from
the trunk 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 + 14 7/–10 6. 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. <

Vehicle equipment
In this chapter, all production, country, and
optional equipment that is offered in the model
range is described. As a result, some equip-
ment described may not be available in a partic-
ular vehicle, for example due to the options or
national-market version selected. This also
applies to safety related functions and systems.
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 ob serve the instructions
contained in the following section.
For additional information on transporting chil-
dren safely, refer to page 56.
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 page 104.
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 page 49.
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 page 52.
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 page 49, and on damaged safety
belts on page 53.
Manual adjustment
Observe the adjustment instructions on
page 47 to ensure the best possible per-
sonal protection.<

Head restraints
Correctly adjusted head restraint
A correctly adjusted head restraint reduces the
risk of neck injury in the event of an accident.
Correctly adjust the head restraints of all
occupied seats; otherwise, there is an
increased risk of injury in an accident. <
Height
Adjust the head restraint so that its center is
approximately at ear level.
Distance
Adjust the distance so that the head restraint is
as close as possible to the back of the head.
Front active head restraints
In a rear collision of a sufficient strength, the
active head restraint reduces the distance to
the head. Do not use seat or head restraint covers
that could impair the function of the active
head restraint.
Do not hang any items, e.g. clothes hangers,
directly on the head restraints. Attach only
BMW approved accessories to the seat or head
restraint.
Otherwise, the protective function of the active
head restraint will not be ensured and its full
potential in reducing the risk of injury in the
event of a rear collision may not be realized.
In the event of faults, immobilization, or after the
active head restraints have been triggered,
have the testing, repair, or disassembly per-
formed only by your BMW center or a workshop
that has the required explosives licenses.
Unprofessional attempts to work on the system
could lead to failure in an emergency or to
undesired airbag activation, either of which
could result in personal injury.<
For technical reasons, the head restraint
cannot be removed. <
