Alarm system*The conceptThe vehicle alarm system responds:
>When a door, the hood or the lug-
gage compartment lid is opened
>To movements 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
>The high beams flash 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 driver's door lock or with the
remote control, the alarm system is also
simultaneously armed or disarmed.You can have different acknowl-
edgment signals set to confirm

ment lid when the system is armed by

rearview mirror flashes continuously:
The system is armed
>The indicator lamp flashes during
arming: the door(s), the hood or the
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 when the
system is disarmed: no manipulation
or attempted intrusions have been
detected in the period since the sys-
tem was armed
>The indicator lamp flashes for
10 seconds when the system is dis-
armed: an attempted entry has been
detected in the period since the sys-
tem was armed.
Following triggering of an alarm, the
indicator lamp will flash continuously.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 from being triggered in garages
with elevator ramps, for instance, or
when the vehicle is transported by train:
Lock the vehicle twice to arm the sys-
tem. Press the button on the remote
control twice in succession or lock the
vehicle twice with the key.
The indicator lamp lights up briefly and
then flashes continuously. The tilt alarm
sensor and the interior motion sensor
are deactivated as long as the system is
armed.
You can have the tilt alarm sensor
and the interior motion sensor
permanently deactivated.<
Interior motion sensor*Deactivate the interior motion sensor –
refer to Avoiding unintentional alarms –
if persons or animals are to remain in
the vehicle.
The system deactivates the tilt-
alarm sensor and the interior
motion sensor if the convenience clos-
ing of windows is interrupted in the first
10 seconds and then restarted. The
alarm must then be disarmed and reac-
tivated before it will resume opera-
tion.<

After the ignition has been
switched offYou can still use the electric power win-
dows for up to 15 minutes, as long as
no one opens any of the doors.Safety featureIf the closing force of a front window
exceeds a certain value as the window
is being closed, the closing procedure
is immediately interrupted and the win-
dow opens again slightly.
Despite this protective function,
you must still make sure that there
are no obstacles within the closing
range of the windows. Otherwise, it
cannot be guaranteed that the closing
procedure will be interrupted in certain
cases, e.g. when very thin objects are
in the closing range.
This protective function is deactivated
when the switch is pulled past the
resistance point and held there. nected, the protective function must be
reinitialized. Please refer the problem to
your BMW center.
Manual convertible topThe fabric top offers the perfect protec-
tion against weather and one person
can open and close it easily and simply.
To gain maximum satisfaction from your
convertible, please observe the follow-
ing: we strongly recommend that you
close the convertible top before leaving
the vehicle parked. When closed, the
top not only guards the passenger
compartment from unforeseeable dam-
age from the weather, but also affords a
degree of protection against theft.
However, even when the top is closed
valuables should always be stored in
the locked luggage compartment.
Never attempt to mount any kind of roof
rack or luggage carrier on the convert-
ible top.
Closing the electric power win-
dows: to help ensure that the win-
dows seal securely, you should either
close the rear windows first or close all
four windows at the same time.<
