Alarm System - BMW SERIE 3 SEDAN 2001 Manual

Alarm system

*
42n
The concept
The vehicle's alarm system responds:
> When a door, the hood or the
luggage compartment lid is opened.
> To movement inside the vehicle
(interior motion sensor).
> To a change of the vehicle's tilt – 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 system responds to unauthorized
vehicle entry and attempted theft by
simultaneously activating the following:
> Sounding an acoustical alarm for
30 seconds.
> The hazard warning flashers are acti-
vated for approx. five minutes.
> The high beams flash on and off in
the same rhythm.
To activate and deactivate the
alarm system
When the vehicle is locked or unlocked
by using a key or with the remote
control, the alarm system is also simul-
taneously armed or disarmed.
The interior motion sensor and the tilt
alarm sensor are activated approx.
30 seconds after you have finished
locking the vehicle.
If the alarm system has been armed
correctly, the hazard warning flashers
flash once.
You can have a signal set as
acknowledgment for both acti-
vating and deactivating the

compartment lid when the system is
armed by pressing button 3 of the
remote control (refer to page 37). When

> 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 remaining
areas, and the indicator lamp flashes
continuously after 10 seconds.
However, the interior motion sensor
is not activated.
> If the indicator lamp goes out when
the system is disarmed: no manipula-
tion or attempted intrusions have
been detected in the period since the
system was armed.
