Alarm system
The concept
The vehicle alarm system responds:
>To the opening of doors, the hood, or the
luggage compartment lid
>To movements in the vehicle interior: inte-
rior motion sensor, see below
>To changes in the vehicle's tilt if someone
attempts to steal the wheels or tow the
vehicle
>To interruptions in battery voltage
The system responds to unauthorized vehicle
entry and attempted theft by simultaneously
activating:
>An acoustic alarm, which lasts for a period
of approx. 30 seconds
>The hazard warning flashers for approx.
5minutes
>The high beams, which flash on and off in
the same rhythm
Arming and disarming alarm system
When you lock or unlock the vehicle, either with
the remote control or at the door lock, the alarm
system is armed or disarmed at the same time.
The system indicates that it has been correctly
armed by switching on the hazard warning
flashers for a single cycle and by emitting an
acoustic signal.
You can also open the luggage compartment lid
with the system armed using the button on
the remote control, refer to page30. When the
luggage compartment lid is closed, it is locked
again and monitored.
Switching off alarm
>Unlock the vehicle using the remote control,
refer to page29,
>or turn the ignition key to position 1, refer to
page54.

Indicator lamp displays
>The indicator lamp below the interior rear-
view mirror flashes continuously: the sys-
tem is armed.
>The indicator lamp flashes after locking:
door(s) or luggage compartment lid are not
completely closed. Even if you do not close
the alerted area, the system begins to mon-
itor the remaining areas, and the indicator
lamp flashes continuously after approx.
10 seconds. However, the interior motion
sensor is not activated.
>The indicator lamp goes out after unlocking:
no manipulation or attempted intrusions
have been detected in the period since the
system was armed.
>After unlocking, the indicator lamp flashes
until the key is inserted into the ignition
lock, but will not do so for longer than
roughly 5 minutes: an attempted entry has
been detected in the period since the sys-
tem was armed.
Tilt alarm sensor and interior motion
sensor
Tilt alarm sensor
Monitors the inclination of the vehicle. The
alarm system reacts, for example, if someone
attempts to steal the wheels or tow the vehicle.
Interior motion sensor
Coupe:
In order for the interior motion sensor to func-
tion properly, the windows and glass sunroof
*
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 sensor, is armed
even if the convertible top is open. Falling
objects, e.g. leaves, can trigger false alarms,
refer to Avoiding unintentional alarms.
Avoiding unintentional alarms
The tilt alarm sensor and interior motion sensor
may be switched off at the same time. This pre-
vents unintentional alarms, e.g. in the following
situations:
>In stacking garages
>When transporting on car-carrying trains
>When animals are to remain in the vehicle
Switching off the tilt alarm sensor and
interior motion sensor
Press the button on the remote control
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 prevent chil-
dren from operating the power windows and
injuring themselves.<

Rear window
Ignition key in position 1 or greater, refer to
page54:
1.Briefly press button1:
The LEDs in button 1 and switch 2 light up.
2.Press switch 2:
>Up to the resistance point:
The rear window continues to open for
as long as you hold the switch.
You can close the rear window in the
same manner by pulling the switch.
>Briefly press the switch beyond the
resistance point:
The rear window opens automatically.
Briefly press the switch again to stop the
opening movement.
Briefly press button 1 again to deactivate the
function. The LEDs go out.
The rear window opens and closes auto-
matically when you open or close the con-
vertible top.<
After switching off ignition
You can still operate the windows:
>for approx. 15 minutes when the ignition
key is in position 1.
>for approx. 1 minute when the ignition key is
in position 0 or has been removed; but in the
convertible, only for as long as a door has
not been opened.
For information on using the convenience oper-
ation mode at the door lock or with the remote
control, refer to page30 or31.
Anti-trapping mechanism
If the closing force rises beyond a predefined
threshold during closing, the system will imme-
diately stop moving the window prior to lower-
ing it slightly.
Convertible: the back windows and rear
window are not equipped with an anti-
trapping mechanism.<
Despite the anti-trapping mechanism,
you should inspect the travel path of the
front side window prior to closing it, as the
safety feature could fail to detect certain kinds
of obstructions, such as very thin objects, and
the window would continue 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 pull the switch past the resistance point
again within approx. 4 seconds and hold it there,
the anti-trapping mechanism will be deacti-
vated.<
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 contact your BMW center for
assistance.
Coupe:
Glass sunroof, electric
with raise function*
To prevent injuries, exercise care when
closing the glass sunroof 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 sunroof and injure them-
selves.<

Raising and closing glass sunroof
Ignition key in position 1 or greater, refer to
page54:
>Briefly press the switch:
The sunroof opens and the sliding visor
moves back approx. 2 in/5 cm
or
press the switch twice past the resistance
point toward the rear:
The sunroof opens and the sliding panel
moves completely back.
>To close, briefly press the switch or push it
twice beyond the resistance point toward
the front:
The sunroof and sliding panel close.
Opening and closing sliding panel
Ignition key in position 1 or greater, refer to
page54:
>Push the switch up to the resistance point in
the desired direction:
The sliding panel continues to move for as
long as you hold the switch.
>Push the switch beyond the resistance
point in the desired direction:
The sliding panel moves automatically.
Briefly press the switch again in any direc-
tion to stop the movement.
After switching off ignition
You can still operate the sunroof:
>for approx. 15 minutes when the ignition
key is in position 1.
>for approx. 1 minute in position 0 or with the
ignition key removed, as long as a door has
not been opened.For information on using the convenience oper-
ation mode at the door lock or with the remote
control, refer to page30 or31.
Anti-trapping mechanism
If the glass sunroof encounters resistance when
closing, the closing action is interrupted and the
glass sunroof opens.
If the sliding panel encounters resistance when
closing within the last approx. 8 in/20 cm, the
closing action is interrupted and the sliding
panel opens again slightly.
Despite the anti-trapping mechanism,
you should inspect the sunroof's travel
range prior to closing it, as the safety feature
might fail to detect certain kinds of obstruc-
tions, such as very thin objects, and the sunroof
would continue closing.
Pressing the switch beyond the resistance
point and holding it deactivates the anti-trap-
ping mechanism.<

power supply
