Anti-theft alarm system*

Once the alarm system has been armed, a
visual and audible alarm is triggered when
someone opens
a door
the tailgate
the hood
The alarm will stay on, even if the
activating element (a door, for example) is
immediately closed.
The alarm system will also be triggered
when
someone attempts to raise the vehicle
opening the vehicle with the
mechanical key
i
If the alarm stays on for more than
20 seconds, an emergency call is
initiated automatically by the Tele Aid
system* ( page 222) provided
Tele Aid service was subscribed to and
properly activated, and that necessary
cellular service and GPS coverage are
available.
Arming the alarm system
The alarm system is armed after locking
the vehicle with the SmartKey. The turn
signal lamps flash three times to indicate
that the alarm system is activated. A red
indicator lamp in the switch for the
tow-away alarm ( page 81) begins to
flash after approx. ten seconds after
arming the alarm system.
