Alarm system
*
The conceptThe vehicle's alarm system responds:
>When a door, the hood or the lug-
gage compartment lid is opened
>To movement inside the vehicle
(interior motion sensor)
>To a change of the vehicle's tilt Ð if
someone attempts to steal the wheels
or tow the vehicle without authoriza-
tion, for example
>If there is an interruption of battery
voltage.
The alarm system signals unauthorized
access to the vehicle or an attempted
theft in different ways:
>Sounding an acoustical alarm for
30 seconds
>The hazard warning flashers are acti-
vated for approx. five minutes.
To activate and deactivate the
alarm systemWhen the vehicle is locked or unlocked
by using a key or with the remote con-
trol, the alarm system is also simulta-
neously armed or disarmed.
The interior motion sensor is activated
approx. 30 seconds after you have fin-
ished locking the car.
If the alarm system has been armed
correctly, the hazard warning flashers
flash once. An acoustic warning signal
sounds at the same time.
You can have different acknow-
ledgment messages set to confirm
arming and disarming.<
You can also open the luggage com-
partment lid when the system is armed
by pressing button 3 of the remote con-
trol (refer to page 37). When it is closed,
the lid is once again secured.
Indicator lamp displaysThe indicator lamp is located under the
interior rearview mirror.
>When the indicator lamp flashes con-
tinuously: The system is armed.
>If the indicator lamp flashes during
arming of the system: The door(s),
the hood or luggage compartment lid
are not completely closed. Even if
you do not close the alerted area, the
system begins to monitor the remain-
ing areas, and the indicator lamp
flashes continuously after 10 sec-
onds. However, the interior motion
sensor is not activated.
>If the indicator lamp goes out when
the system is disarmed: No manipu-
lation or attempted intrusions have
been detected in the period since the
system was armed.460de105

Do not work on your vehicle
without appropriate skills. Always
switch off the engine and allow it to
cool down before working in the engine
compartment. Always disconnect the
battery before working on any electrical
systems or equipment, especially when
these are located within the engine
compartment. Comply with all applica-
ble instructions and warnings. Failure to
work in an informed, professional man-
ner when servicing components and
materials constitutes a safety hazard
for vehicle occupants and other road
users. If you are not familiar with the
guidelines, please have the operations
performed by your BMW center.<
