Alarm system
41n
> If the indicator lamp flashes for
10 seconds when the system is
disarmed: 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
The tilt alarm sensor and interior motion
sensor may be switched off at the same
time. By doing this, you can prevent
false alarms on garage ramps or when
the vehicle is transported by trailer or
train, for instance.
Lock the vehicle twice (= arm the system).
In other words, press button 2 of
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 for as long as the system
remains armed.

Interior motion sensor
The transmitter and receiver of the interior
motion sensor are located in a trim
panel in the vehicle's headliner.
In order for the interior motion sensor to
function properly, the windows and
sliding/tilt sunroof must be completely
closed.
Nevertheless, you should deactivate the
interior motion sensor whenever
> children or animals are left in the
vehicle
> the windows and/or sunroof are left
open.
Emergency deactivation
procedure
If the car is locked and it is not possible
to disarm the system in the normal
manner, proceed as follows:
1 Use the key to unlock the door (the
alarm sounds for 30 seconds when
opening the door)
2 Turn the key to ignition key position
1; the central locking system
unlocks the remaining doors.
The alarm system is now disarmed. Refer
the problem to your BMW center.
