Arming and disarming
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.
You can open the luggage compartment lid
using the button of the remote control even
if the alarm system is armed, refer to page20.
The lid is locked and monitored again as soon
as it is closed.
Panic mode
You can trigger the alarm system if you find
yourself in a dangerous situation.
Press the button for at least three seconds.
To switch off the alarm: press any button.
Switching off an alarm
>Unlock the car with the remote control, refer
to page19, or
>insert the remote control all the way into the
ignition lock.
Indicator lamp displays
>The indicator lamp under the inside rear-
view mirror flashes continuously: the sys-
tem is armed.
>The indicator lamp flashes after locking:
doors, hood or luggage compartment lid are not properly closed. Even if you do not
close the alerted area, the system begins to
monitor the remaining areas, and the indi-
cator lamp flashes continuously after
approx. 10 seconds. The interior motion
sensor and the tilt alarm sensor are not acti-
vated.
>The indicator lamp goes out after unlocking:
your vehicle has not been disturbed while
you were away.
>If the indicator lamp flashes after unlocking
until the remote control is inserted in the
ignition, but for no longer than approx.
5 minutes: your vehicle has been disturbed
while you were away.
Tilt alarm sensor
The tilt of the vehicle is monitored. The alarm
system reacts, e.g. to attempts to steal a wheel
or tow the vehicle.
Interior motion sensor
Coupe
In order for the interior motion sensor to func-
tion properly, the windows and glass roof must
be completely closed
*.
Convertible
The interior of the car is monitored up to the
height of the seat cushions. Thus the alarm sys-
tem is activated together with the interior
motion sensor even if the convertible top is
open. The alarm can be triggered unintention-
ally by falling objects such as leaves, 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 duplex garages
>During transport on car-carrying trains,
boats/ships or on a trailer
>When animals are to remain in the vehicle

prior to closing it, otherwise the safety system
might fail to detect certain kinds of obstruc-
tions, such as thin objects, and the window
would continue closing.
Do not install any accessories that might inter-
fere with window movement. Otherwise the
pinch protection system could be impaired.
Convertible: the rear windows are not equipped
with pinch protection. Therefore, watch them
closely when closing to avoid personal injury.<
Closing without pinch protection
If there is an external danger, or if ice on the win-
dows, etc., prevents you from closing the win-
dows normally, proceed as follows:
1.Pull the switch past the resistance point and
hold it there. Pinch protection is limited and
the window reopens slightly if the closing
force exceeds a certain value.
2.Pull the switch again past the resistance
point within approx. 4 seconds and hold it
there. The window closes without pinch
protection.
Coupe: glass roof*, electric
To prevent injuries, watch the glass roof
while closing it.
Take the remote control with you when you
leave the car, otherwise children could operate
the roof and possibly injure themselves.<
Raising
Press the switch.
>The closed glass roof is raised and the slid-
ing visor opens slightly.>The open glass roof automatically travels
into the raised position. The sliding visor
remains completely open.
Do not close the sliding visor forcibly with
the roof in the raised position, as this
would damage the mechanism.<
Opening, closing
>Press the switch backwards to the resis-
tance point.
The glass roof and the sliding visor open
together as long as you hold the switch in

visor remains open and can be closed by hand.
For information on convenient operation via the
remote control or the door lock, refer to page19
or22. For information on closing with conve-
nient access, refer to Locking on page26.
After switching off the ignition
When the remote control is removed or the igni-
tion is switched off, you can still operate the roof
for approx. 1 minute as long as no door has
been opened.
Pinch protection system
If the glass roof encounters an obstruction dur-
ing closing from approximately the middle of
the opening in the roof, or during closing from
the raised position, the closing movement is
interrupted and the glass roof is opened again
slightly.
Despite the pinch protection system
check and clear the roof's travel path prior
to closing it, otherwise the safety system might
fail to detect certain kinds of obstructions, such
as very thin objects, and the roof would con-
tinue closing.<

LEDs
>While the convertible top is being operated,
the left LED lights up green. It goes out as
soon as the top is fully opened or closed.

The automatic sequence of movements is
interrupted if the button for the convertible top
operation is released. The sequence can be
continued in the desired direction by pushing or
pulling the buttons.
If the opening or closing procedure is inter-
rupted for an extended period, the convertible
top remains in the raised position for approx.
10 minutes and then slowly moves to a stable
position.

not be opened and the windows cannot be
moved.<

Lamps and bulbs
Lamps and bulbs make an essential contribu-
tion to vehicle safety. They should, therefore,
be handled carefully. BMW recommends hav-
ing your BMW center perform any work that you
do not feel competent to perform yourself or
that is not described here.
Never touch the glass of new bulbs with
your bare fingers, as even minute
amounts of contamination will burn into the
bulb's surface and reduce its service life. Use a
clean tissue, cloth or something similar, or hold
the bulb by its base.<
You can obtain a selection of replacement bulbs
at your BMW center.When working on electrical systems,
always begin by switching off the con-
sumer in question, otherwise short-circuits
could result. To avoid possible injury or equip-
ment damage when replacing bulbs, observe
any instructions provided by the bulb manufac-
turer.<
If the routine for changing a particular
bulb is not described here, please contact
your BMW center or a workshop that works
according to BMW repair procedures with cor-
respondingly trained personnel.<
Light-emitting diodes LED
Light-emitting diodes installed behind translu-
cent lenses serve as the light source for many of
the controls and displays in your vehicle. These
light-emitting diodes, which operate using a
concept similar to that applied in conventional
lasers, are officially designated as Class 1 light-
emitting diodes.
Do not remove the covers or expose the
eyes directly to the unfiltered light source
for several hours, otherwise this could cause
irritation to the retina.<
Xenon lamps*
These bulbs have a very long service life and are
highly unlikely to fail. If a xenon bulb fails never-
theless, switch on the fog lamps and continue
the journey with great care, provided that local
legislation does not prohibit this.
Have any work on the xenon lamp system,
including bulb replacements, performed
only by a BMW center or a workshop that works
according to BMW repair procedures with cor-
respondingly trained personnel. Otherwise, if
such work is carried out improperly, the high
voltage in the system presents the danger of
fatal injuries.<
