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.<

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.<

Convertible: top
The fully automatic convertible top combines
secure weather protection with simple and con-
venient operation.
So that you get the maximum pleasure from
your convertible, here are a few tips:
>It is advisable to close the convertible top
when the vehicle is parked. The closed con-
vertible top not only protects the passenger
compartment against unforeseen weather
damage, it also provides a certain amount of
protection against theft. Nonetheless, even
if the convertible top is closed, only keep
valuables in the locked luggage compart-
ment.
>Do not attach luggage rack systems to the
convertible top.
In order to avoid damage, do not operate
the convertible top at temperatures
below + 147/–106.
Do not leave the convertible top in its storage
compartment for longer than one day when wet,
as otherwise damage from moisture can occur.
Do not place any objects on the convertible top,
as otherwise if the top were to be operated,
these objects could fall off and lead to damage
or injury.
Never move the convertible top when the roll-
over protection system is raised.
Driving without having completed the opening
or closing action can lead to damage or injury.
Do not place hands in the top mechanism dur-
ing the opening and closing action. Keep chil-

Opening and closing
40 dren away from the travel path of the convert-
ible top.
For safety reasons, only operate the convertible
top when the vehicle is at a standstill.<
If you have initiated top operation with the
vehicle at a stop and then start to drive,
e.g. at a traffic light, you can continue the ini-
tiated operation up to a speed of 20 mph/
30 km/h:
To do so, press and hold the corresponding
button.<
Partial vacuums that occur at higher
speeds in the passenger compartment
can make the convertible top flap. Use the auto-
matic climate control to increase the air supply
so that a partial vacuum in the vehicle does not
occur.<
Prior to opening and closing
>Read carefully and comply with the safety
precautions that appear above.
>Ensure that the convertible top compart-
ment floor in the luggage compartment is
folded down, refer to page34, as otherwise
the convertible top cannot be opened.
>Ensure that the luggage compartment lid is
closed.
Opening and closing
With the ignition key in position 1 or greater,
refer to page54, and the vehicle stationary:
So as not to place an excessive load on
the battery, only operate the convertible
top with the engine running, if possible.
Before closing the convertible top, remove for-
eign bodies from the windshield frame, as these
might inhibit closing of the convertible top.<1Closing

When the button for top operation is
pressed, the side windows move down-
ward slightly; the rear window is lowered com-
pletely.
If you hold down the button after the LED2
goes out, the windows are raised again.
If the opening or closing action is not com-
pleted, the luggage compartment lid cannot be
opened.<
LED
In the following situations, in addition to the
LED, a message is displayed on the Control
Display and an acoustic signal may sound:
>During convertible top operation, the LED
lights up green. It goes out as soon as the
opening or closing action is ended.
> If the LED flashes red when you release the
button, the opening or closing action has
not yet finished.
>If the LED lights up red when the button is
pressed, either the floor of the convertible
top storage compartment in the luggage
compartment is in the raised position or a
malfunction has occurred. The convertible
top cannot be moved.
Interruption
The automatic sequence of movements is
interrupted immediately if the button for top
operation is released. The sequence can be
continued in the desired direction using the
button.
If the opening or closing action is interrupted for
a longer period, the convertible top remains in
that position for approx. 15 minutes before it
slowly moves to a stable position.
A convertible top which is not completely
opened or closed presents a danger.
Do not interrupt and continue the closing action
several times in succession, as otherwise the
top mechanism can be damaged.<
