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 remote control or the driver's
door lock, the alarm system is also
simultaneously armed or disarmed.You can have different acknowl-
edgment signals set to confirm
arming and disarming.<
You can open the luggage compart-
ment lid when the system is armed by

Indicator lamp displays>The indicator lamp below the interior
rearview mirror flashes continuously:
The system is armed
>The indicator lamp flashes immedi-
ately after the vehicle is locked: doors
or 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 immedi-
ately after the vehicle is unlocked: no
manipulation or attempted intrusions
have been detected in the period
since the system was armed
>The indicator lamp flashes for
10 seconds immediately after the
vehicle is unlocked: an attempted
entry has been detected in the period
since the system was armed.
Following triggering of an alarm, the
indicator lamp will flash continuously.Tilt alarm sensor and interior
motion sensorTilt alarm sensor:
The tilt of the vehicle is monitored. The
alarm system reacts, for example, to
attempts to steal the wheels or tow the
vehicle.
Interior motion sensor:
The vehicle interior is monitored up to
the height of the seat cushions. Even
when the convertible top is open, the
alarm system including the interior
motion sensor is armed. Objects falling
into the vehicle, e.g. leaves, can trigger
unintentional alarms, refer to Avoiding
unintentional alarms.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, e.g. in the following situations:
>In garages with elevator ramps>When the vehicle is being trans-
ported by train
>When animals are to remain in the
vehicle.
To deactivate the tilt alarm and
interior motion sensors>Press the button on the remote con-
trol twice.
The indicator lamp lights up briefly and
then flashes continuously. The tilt alarm
sensor and the interior motion sensor
are deactivated until the vehicle is
unlocked and locked again.
You can have the tilt alarm sensor
and the interior motion sensor
permanently deactivated.<
The system inadvertently deacti-
vates the tilt alarm sensor and the
interior motion sensor if the conve-
nience closing of windows and glass
sunroof is interrupted within the first
10 seconds and then restarted. The
vehicle must then be unlocked and
relocked before the sensors will resume
operation.<

Despite trap protection, always
make sure that the windows can
close without obstruction, otherwise in
some cases, e.g. with thin objects, it is
not guaranteed that the closing opera-
tion will be interrupted.
Trap protection is restricted when the
switch is pulled and held beyond the
pressure point. In this instance, if the
closing force exceeds a certain value,
the window will re-open just a few milli-
meters.
If the switch is pulled and held beyond
the pressure point again within approx.
4 seconds, trap protection is overrid-
den.<
After a power lossAfter the battery has been discon-
nected, the trap protection must be
reinitialized. Perform the following pro-
cedure twice:
>Open and close the window com-
pletely
>With the window closed, keep pulling
the switch for approx. 1 second.
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.<

tion of a combination lap/shoulder belt.

restraint systems can increase the risk
of injury to children. Always read and
follow the instructions that come with
the system.
Correct location for installingIn your BMW, all seats equipped with a
three-point safety belt – except for the

sponding anchorage point to secure the
child-restraint system, as shown in the
illustration.
1. Open the convertible top compart-
ment lid, refer to page 39 or 44
2. Lift the headrest and pass the tether
strap between the headrest and the
