Anti-theft alarm system

Once the alarm system has been armed, a
visual and audible alarm is triggered when
someone opens:
a door
the trunk
the hood
The alarm will stay on even if the activating
element (a door, for example) is immedi-
ately closed.
The alarm system will also be triggered
when
the vehicle is opened with the
mechanical key.
a door is opened from the inside.
the trunk is opened with the
emergency release button.
To cancel the alarm after it has been trig-
gered, see "Canceling the alarm"
( page 67).

If the alarm stays on for more than
30 seconds, a call to the Response Center is
initiated automatically by the Tele Aid* system
( page 295) provided Tele Aid* service was
subscribed to and properly activated, and that
necessary mobile phone, power supply and GPS
coverage are available.
