Indicator lamp displays
>The indicator lamp below the interior
rearview mirror flashes continuously:
the system is armed
>The indicator lamp flashes on locking:
door(s) or luggage compartment lid are
not completely closed. Even if you do
not close the alerted area, the system
begins to monitor the remaining areas,
and the indicator lamp flashes continu-
ously after approx.10 seconds. How-
ever, the interior motion sensor is not
activated
>The indicator lamp goes out on unlock-
ing: no manipulation or attempted intru-
sions have been detected in the period
since the system was armed
>The indicator lamp flashes on unlocking
before the remote control is inserted in
the ignition lock, but for no more than
roughly 5 minutes: an attempted entry
has been detected in the period since
the system was armed.
Following triggering of an alarm, the indica-
tor lamp will flash continuously.
Tilt alarm sensor and interior motion
sensor
Tilt alarm sensor
Monitors the inclination of the vehicle. The
alarm system reacts, for example, if some-
one attempts to steal the wheels or tow the
vehicle.
Interior motion sensor
Coupe:
In order for the interior motion sensor to
function properly, the windows and glass
roof must be completely closed.
Convertible:
Monitors the interior up to the height of the
seat cushions. This means that the alarm
system, including the interior motion sen-
sor, is armed even if the convertible top is
open. Falling objects, e.g. leaves, can trig-
ger false alarms, refer to Avoiding uninten-
tional alarms.
Avoiding unintentional alarms
The tilt alarm sensor and interior motion
sensor may be switched off at the same
time. This is how you prevent unintentional
alarms, e.g. in the following situations:
>In garages with elevator ramps
>During transport on automobile trans-
port trains
>If animals are to remain in the vehicle.
Switching off tilt alarm sensor and
interior motion sensor
Press the button on the remote con-
trol once again directly after locking.
The indicator lamp lights up briefly and
then flashes continuously. The tilt alarm
sensor and the interior motion sensor are
switched off until the vehicle is unlocked
and locked again.
Windows
To prevent injuries, exercise care
when closing the windows and keep
them in your field of vision until they are
shut.
When leaving the vehicle, always remove
the ignition key and close the doors to pre-
vent children from operating the windows
and injuring themselves etc.<

2.Press switch 2:
>Up to the resistance point:
The rear window continues to move
downward as long as you continue

remote control, refer to page 27 or 29.
Anti-trapping mechanism
If the closing force rises beyond a pre-
defined threshold during closing, the sys-
tem will immediately stop moving the win-
dow prior to lowering it slightly.
Convertible: the back windows and
rear window are not equipped with an
anti-trapping mechanism.<
Despite the anti-trapping mechanism,
you should always inspect the front
side window's travel path prior to closing it,
as the safety feature might fail to detect
certain kinds of obstructions, such as very
thin objects, and the window would con-
tinue closing.
Pulling the switch beyond the resistance
point and holding it limits the response of
the anti-trapping mechanism. Under these
conditions, the window will respond to
forces beyond a defined threshold by only
opening a few inches/millimeters.
If you again pull the switch past the resis-
tance point and hold it in position within a
period of roughly 4 seconds, the anti-trap-
ping mechanism will be deactivated.<
Accessories in window area
After installing any accessory – such as a
clamp-on antenna for a portable phone –
within the window's travel range, you will
need to have the system reinitialized for
use under the new conditions. Please con-
tact your BMW center for assistance.
Coupe:
Glass roof, electric with
raise function*
To prevent injuries, exercise care
when closing the glass roof and keep
it in your field of vision until it is shut.
When leaving the vehicle, always remove
the key and close the doors, as otherwise
children could operate the roof and injure
themselves etc.<

Seats
Note before adjusting
Never attempt to adjust your seat
while operating the vehicle. The seat
could respond with unexpected move-
ment, and the ensuing loss of vehicle con-
trol could lead to an accident.
On the front passenger side as well, do not
tilt the backrest too far toward the rear
while driving. Failure to observe this pre-
caution can prevent the belt from providing
effective protection against injury, as the
passenger could slide under the belt in an
accident.
Make sure that the footwell behind the
driver's and front passenger's seat is empty
and unobstructed. If you fail to do so, any
persons or objects behind the seat could
be injured or damaged by a rearward
movement of the seat.<
Also observe the instructions regarding
damage to the safety belt on page 47.
Convertible: with the wind deflector
fitted, do not incline the front seat
backrests too far backwards if the seat is to
be moved back to the end position, as oth-
erwise the wind deflector will be dam-
aged.<
Seat adjustment
To ensure that the safety systems
continue to provide optimized protec-
tion, please observe the adjustment
instructions above.<

Transporting children safely
The right place for children
Children always in the rear
Accident research shows that the safest
place for children in a vehicle is in the rear
seat.
Older children should be tightly secured
with a safety belt, after they have outgrown
a booster seat that is appropriate for their
age, height and weight.
Child-restraint system in the rear
Children under 13 years of age and
children less than 5 ft/150 cm tall
should always ride in the rear and the
restraint systems should be secured with
the vehicle's safety belts.<
Younger children should be secured in an
appropriate forward-facing child-restraint
system that has first been properly
secured. We strongly urge you to carefully
read and comply with the instructions for
installation and use provided by the child-
restraint's manufacturer whenever you use
such a device.
All rear sitting positions in your vehicle
meet the recommendations of SAE J1819,
an industry-recommended practice for
securing child-restraint systems in motor
vehicles.
Exception for front passenger seat
Should it become necessary to use
a child-restraint system on the front
passenger seat, the airbags on the passen-
ger's side must be deactivated. Deactivat-
ing the passenger airbags is only possible
on the Coupe. Your BMW center will be
glad to advise you. restraint system in the front passen-
ger seat of this vehicle if the passenger air-
bag is not deactivated. If you do so, the
child could be severely injured when the
airbag is triggered.
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 Ibs./9 kg – would be within the air-
bag's deployment range, you should never
mount such a system in the front passenger
seat, since the impact of the airbag against
the child restraint's backrest could lead to
serious or fatal injuries.<
Installing child-restraint
systems
Before installing any child-restraint system
or child seat, read the following:
Observe the child-restraint system
manufacturer's instructions for instal-
lation and use. Otherwise the degree of
protection can be reduced.
After an accident, have all parts of the
child-restraint system and of the relevant
vehicle safety belt system checked by a
BMW center and replaced if necessary.<
Commercially-available child-restraint sys-
tems are designed to be secured with a lap
belt or with the lap belt portion of a combi-
nation lap/shoulder belt. Improperly or
inadequately installed restraint systems
can increase the risk of injury to children.
Always read and follow the instructions that
come with the system.
