Alarm system*The conceptThe vehicle alarm system responds:
>When a door, the hood or the lug-
gage compartment lid are opened
>To movement inside the vehicle –
interior motion sensor
>To variations in the vehicle's tilt angle
such as those occurring during
attempts to steal the wheels or tow
the vehicle – tilt alarm sensor
>To interruption of battery voltage.
The system responds to unauthorized
vehicle entry and attempted theft by
simultaneously activating the following:
>The acoustic alarm sounds for
30 seconds
>The hazard warning flashers are acti-
vated for approx. five minutes
>Flashing the high beams on and off in
rhythm with the hazard warning flash-
ers.To arm and disarm the alarm
systemWhen the vehicle is locked or unlocked
via the remote control or the driver's
door lock, the alarm system is also
simultaneously armed or disarmed.You can have a signal set as con-
firmation that the alarm system
has been armed or disarmed.<
You can also open the luggage com-
partment lid when the system is armed
by pressing the button of the remote
control. When it is closed, the lid is
once again secured.
Extended pressure on the button sets
off the alarm – Panic mode, refer to
page 30.

Indicator lamp displays>The indicator lamp below the interior
rearview mirror flashes continuously:
the system is armed
>The indicator lamp flashes immedi-
ately after the vehicle is locked: doors
or luggage compartment lid are not
completely closed. Even if you do not
close the alerted area(s), the remain-
ing areas are secured, and the indi-
cator lamp will flash continuously
after 10 seconds. However, the inte-
rior motion sensor is not activated
>The indicator lamp goes out immedi-
ately after the vehicle is unlocked: no
manipulation or attempted intrusions
have been detected in the period
since the system was armed
>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.
Following triggering of an alarm, the
indicator lamp will flash continuously.Tilt alarm sensor and interior
motion sensorTilt alarm sensor:
The tilt of the vehicle is monitored. The
alarm system reacts, for example, to
attempts to steal the wheels or tow the
vehicle.
Interior motion sensor:
The vehicle interior is monitored up to
the height of the seat cushions. Even
when the convertible top is open, the
alarm system 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 alarmsThe tilt alarm sensor and interior motion
sensor may be switched off at the same
time. You can do this to prevent a false
alarm, e.g. in the following situations:
>In garages with elevator ramps>When the vehicle is being trans-
ported by train
>When animals are to remain in the
vehicle.
Deactivating the tilt alarm and
interior motion sensors>Press the button on the remote con-
trol twice.
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
unlocked and locked again.
You can have the tilt alarm sensor
and the interior motion sensor
permanently deactivated.<
The system deactivates the tilt
alarm sensor and the interior
motion sensor if the convenience clos-
ing of windows and glass sunroof is
interrupted within the first 10 seconds
and then restarted. The vehicle must
then be unlocked and relocked before
the sensors will resume operation.<

Transporting children safely
Leave the rear safety belts in the
holders if they are not needed to
avoid unwanted movement from the
safety belts at high speeds.<
Commercially available child seats
complying with the legal standard are
designed to be secured with a seat belt
or with the seat belt portion of a combi-
nation lap/shoulder belt. Improperly or
inadequately installed restraint sys-
tems can increase the risk of injury to
children. Always read and follow the
instructions that come with the system.
Correct location for installingIn your BMW, all seats equipped with a
three-point safety belt – except for the
driver's seat – are suitable for installing
universal child-restraint systems of all
age classes and which have been
approved for the age group in question.
Child-restraint system with tether
strapIf you use a child-restraint system with
a tether strap, two additional tether
anchorage points have been provided.
Depending on the location selected for
seating in the rear passenger area,
attach the tether strap to the corre-
sponding anchorage point to secure the
child-restraint system, as shown in the
illustration.
1. Open the convertible top compart-
ment lid, refer to page 39
2. Lift the headrest and pass the tether
strap between the headrest and the
seat back. It is recommended that
you return the head restraint back to
its lowest possible position
3. Adjust the tether strap according to
the child-restraint manufacturer's
instructions
4. Close the convertible top compart-
ment panel.

59
It is recommended to cover the child-
restraint attaching clip with a soft mate-
rial to prevent damage to the stored
soft top.
Should a hard top be installed, the
fitting of child harness tether
strap/s – if child seat is required – is
necessary before installation of the
hard top.<
Before installing any child-
restraint device or child seat,
please read the following:
Never install a rearward-facing child-
restraint system in the front passenger
seat of this vehicle.
Your vehicle is equipped with an airbag
supplemental restraint system for the
front passenger. Because the backrest
on any rearward-facing child-restraint
system – of the kind designed for
infants under 1 year and 20 lbs/9 kg –
would be within the airbag's deploy-
ment range, you should never mount
such a device in the front passenger
seat, as the impact of the airbag against
the child restraint's backrest could lead
to serious or fatal injuries.
If it is necessary for a child – not an
infant – to ride in the front seat, certain
precautions should be taken. First,
move the passenger seat as far away
from the instrument panel as possible.
This important precaution is intended to
maximize the distance between the air-
bag and the child. Older children
should be tightly secured with the
safety belt after they have outgrown a
booster seat that is appropriate for their
age, height, and weight.
Younger children should be secured in
an appropriate forward-facing child-
restraint system that has first been
properly secured with a safety belt.
Never install a rearward-facing child-
restraint system in the front passenger
seat.
We strongly urge you to carefully read
and comply with the instructions for
installation and use provided by the
child restraint's manufacturer when-
ever you use such a device.
Do not attempt to modify child-restraint
systems. If you do this, the protection
provided by these systems could be
impaired.
Be sure that all occupants – of all ages –
remain properly and securely restrained
at all times.<
All rear seating positions in your vehicle
meet the recommendations of
SAE J1819, an industry-recommended
practice for securing child-restraint sys-
tems in motor vehicles.
