Alarm System - BMW X3 2004 Owner's Manual

If the glass roof and sliding panel are
closed:
Press the switch once.<
Anti-trapping mechanism
If the glass roof and sliding panel encoun-
ter resistance when closing from roughly
one third of the roof opening or when clos-
ing from the raised position, the closing
action is interrupted and the glass roof and
sliding panel reopen a little.
Despite the anti-trapping mechanism
you should always inspect the roof's
travel path prior to closing it, as the safety
system might fail to detect certain kinds of
obstructions, such as very thin objects, and
the window would continue closing.
The anti-trapping mechanism for closing
the panorama glass roof is deactivated if
the switch is pressed beyond the resis-
tance point and held there. The closing
action is interrupted when you release the
switch.<
Following interruptions in electrical
power supply
Following interruptions in electrical power,
for instance, when the battery is discon-
nected, it is possible that the glass roof will
extend to its tilt-up position, but fail to
respond to other commands. For initializa-
tion, please contact your BMW Sports
Activity Vehicle Center.
Manual operation
In the event of an electrical malfunction,
you can operate the glass roof manually:

Alarm system*

The concept
The vehicle alarm system responds:
When a door, the hood, or the tailgate is
>
opened
To movement in the vehicle's interior –
>
interior motion sensor
To variations in the vehicle tilt angle
>
such as occur during attempts to steal
the wheels or tow the vehicle
To interruption of battery voltage.
>
The system responds to unauthorized vehi-
cle entry and attempted theft by simulta-
neously activating:
An acoustic alarm, which lasts for a
>
period of approx. 30 seconds
The hazard warning flashers for approx.
>
5 minutes
