Clothes hooks
Clothes hooks1 are located on the wind deflec-
tor panels in the rollover bars.
Do not hang heavy objects on the hooks.
If you do, they could endanger the pas-
sengers, for example during braking or evasive
maneuvers.<
Storage
For storage, e.g. to achieve a better view to the
rear when the convertible top is closed, there
are two brackets on the inside of the luggage
compartment lid.
Insert the wind deflector into the brackets.
Make sure that the wind deflector cannot
be damaged by objects in the luggage
compartment.<
Alarm system*
The concept
The vehicle alarm system responds:
>When a door, the hood or the luggage com-
partment lid is opened
>When attempts are made to start the vehi-
cle
>When there are movements in the vehicle
interior: interior motion sensor, refer to
page26
>To alterations in the vehicle tilt, e.g. as
would occur during attempts to steal the
wheels or tow the vehicle
>To interruption of battery voltage.
The alarm produced by the system in the event
of unauthorized vehicle entry and attempted
theft depends on the country version:
>Sounding of an acoustical alarm for
30 seconds
>Activation of the hazard warning flashers for
approx. five minutes.
Arming and disarming the alarm
system
When the vehicle is locked or unlocked either
with the remote control or at the driver's door
lock, the alarm system is simultaneously armed
or disarmed.
The hazard warning flashers blink once when
the alarm system has been properly armed.
You can have different acknowledgment
signals set to confirm arming and disarm-
ing.<
You can still open the luggage compartment
even when the system is armed by pressing the
button on the remote control, refer to
page17. When it is closed, the lid is once again
secured.
Manual operation of the luggage com-
partment lid triggers the alarm. Refer to
page18.<

Opening and closing

Stopping the alarm
>Unlock the vehicle with the remote control,
refer to page16
>or turn the ignition key to position 1, refer to
page36.
Indicator lamp displays
>The indicator lamp beneath the interior mir-
ror flashes continuously:
The system is armed
>The indicator lamp flashes immediately
after the vehicle is locked:
Doors or luggage compartment lid are not
completely closed. Even if you do not close
the area causing the alert, the remaining
areas are secured and the indicator lamp
flashes continuously after 10 seconds.
However, the interior motion sensor is not
activated
>If the indicator lamp goes out immediately
after the vehicle is unlocked:
No manipulation or attempted intrusions
have been detected in the period since the
system was armed
>If the indicator lamp flashes for 10 seconds
immediately after the vehicle is unlocked:
An attempted entry has been detected in
the period since the system was armed.
After an alarm has been triggered, the indicator
lamp will flash continuously.
Tilt alarm sensor and interior motion
sensor
Tilt alarm sensor
The inclination of the vehicle is monitored. The
alarm system reacts, e.g. to attempts to steal
the wheels or tow the vehicle.
Interior motion sensor*
The system monitors the footwells and the
seating areas of the driver and passenger. Even
when the convertible top is open, the alarm sys-
tem including the interior motion sensor is
armed. Objects falling into the vehicle, e.g.
leaves, can trigger unintentional alarms, refer to
Avoiding unintentional alarms.
Avoiding unintentional alarms
The tilt alarm sensor and interior motion sensor
can be deactivated at the same time. In this way
you can avoid unintentional alarms, e.g. in the
following situations:
>In duplex garages
>When the vehicle is being transported on a
car-carrying train
>If animals are to be left in the vehicle.
To deactivate the tilt alarm and interior
motion sensors
Press the button on the remote control
a second time immediately after locking.
The indicator lamp lights up briefly and then
flashes continuously. The tilt alarm sensor and
the interior motion sensor are deactivated until
the vehicle is again unlocked and locked.

Adjustments
Safe seating position
For relaxed driving with as little fatigue as pos-
sible, you should select a seating position that
reflects your personal requirements. In combi-
nation with the safety belts and airbags, the cor-
rect seating position also plays an important
role in enhancing occupant safety in the event
of an accident. To ensure that the vehicle's
safety systems provide you with optimal pro-
tection, we request that you direct your careful
attention to the following section.
For supplementary information on transporting
children refer to page33.
Airbags
Always maintain an adequate distance
between yourself and the airbags. Always
hold the steering wheel by its rim with hands at
the 9 and 3 o'clock positions to minimize the
r i s k o f i n j u r i e s t o y o u r h a n d s o r a r m s i n t h e e v e n t
of airbag deployment.
Never allow any objects, individuals or animals
to obstruct the areas between passengers and
airbags.
Never use the front airbag's cover as a storage
tray or support for objects of any kind. Ensure
that the passenger is correctly seated, i.e. does
not prop feet or legs against the dashboard.
Otherwise, leg injury could result if the knee air-
bag and front airbag suddenly deployed.
Never let an occupant's head rest near or on a
side airbag because the inflating airbag could
cause a serious or fatal injury.<
Even when all these guidelines are observed,
the risk of injury as a result of contact with the
airbags cannot entirely be ruled out in some sit-
uations. In sensitive individuals, the ignition and
inflation noise may induce a mild hearing loss
that is temporary in most cases.
For airbag locations and additional information
on airbags, refer to page53.
Safety belts
Always fasten your safety belt before starting
off. As supplemental restraint devices, the air-
bags are designed to enhance the effective-
ness of the safety belts, and not to replace
them.
Your vehicle offers two sitting positions, each of
which is equipped with a safety belt.
At all times, occupants should sit upright
and be properly restrained: infants and
small children in appropriate child-restraint sys-
tems; larger children and adults using the safety
belts.
Expectant mothers should always wear their
safety belts, taking care to position the belt in
the pelvic area against the lower hips, where it
will not exert pressure against the abdomen.
N e v e r a l l o w m o r e t h a n o n e p e r s o n t o w e a r a si n -
gle safety belt. Never allow infants or small chil-
dren to ride in a passenger's lap.
Do not route the belt across your neck, or run it
across sharp edges. Be sure that the belt does
not become caught or jammed. Avoid twisting
the belt while routing it firmly across the hips
and shoulder; wear it as snugly against your
body as possible. Do not allow the belt to rest
against hard or fragile objects. Otherwise, the
belt in the pelvic area could slide over the hips in
the event of a frontal impact, leading to abdom-
inal injury. Avoid wearing bulky clothing and pull
the belt in the upper-body area upward periodi-
cally to retension it. Otherwise, the restraining
effect of the safety belt could be diminished.<
For information on using the safety belts, refer
to page30.

Seats
Before adjusting your seat, always
observe the following precautions
Never try to adjust your seat while operat-
ing the vehicle. The seat could respond
with an unexpected movement, and the ensu-
ing loss of vehicle control could result in an
accident.
Never ride with the backrest inclined to an
extreme angle – this also applies to the passen-
ger seat. If you do, there is a risk that you will
slide under the safety belt in the event of an
accident, thus reducing the protection provided
by the safety belt.<
In addition, observe the instructions regarding
damaged safety belts on page30.

Damaged safety belts
If the safety belts are damaged or
stretched in an accident: have the entire
belt system, including the tensioning mecha-
nisms, replaced at your BMW center. Have the
belt anchorage points inspected for damage at
the same time. Failure to observe this precau-
tion may prevent the safety belts from effec-
tively providing optimal protection when
needed.<
