Alarm system
The concept
The vehicle alarm system responds:
>
When a door, the hood, or the luggage
compartment lid is opened
>
To movement in the vehicle's interior –
interior motion sensor
>
To changing the vehicle's tilt if someone
attempts to steal the wheels or tow the
vehicle
>
To interruption of battery voltage.
The system responds to unauthorized
vehicle entry and attempted theft by simul-
taneously activating:
>
An acoustic alarm, which lasts for a
period of approx. 30 seconds
>
The hazard warning flashers for approx.
five minutes
>
The high beams, which flash on and off
in the same rhythm.
Arming and disarming the alarm
system
When you lock or unlock the vehicle, either
with the remote control unit or at the door
lock, the alarm system is armed or dis-
armed at the same time.
The system indicates that it has been cor-
rectly armed by switching on the hazard
warning flashers for a single cycle and by
emitting an acoustic signal.
You can have different acknowledg-
ment signals set to confirm arming
and disarming.
<
You can open the luggage compartment
lid even if the alarm is armed using
button 3
of the remote control, refer
. It is armed once again when
the lid is closed.
Pressing the Panic mode button for a
longer period triggers the alarm, refer
.
<
Indicator lamp displays
>
The indicator lamp below the interior
rearview mirror flashes continuously:
the system is armed
>
The indicator lamp flashes when the
system is armed: door(s), the hood or
luggage compartment lid are not com-
pletely 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
>
The indicator lamp goes out when the
system is disarmed: no manipulation or
attempted intrusions have been
detected in the period since the system
was armed
>
If the indicator lamp flashes for roughly
5 minutes when you disarm the system,
or until the remote control unit is
inserted in the ignition lock: an
attempted entry has been detected in
the period since the system was armed.
Following triggering of an alarm, the indi-
cator lamp will flash continuously.
Avoiding unintentional alarms
The tilt alarm sensor and interior motion
sensor may be switched off at the same
time. You can do this to prevent a false
alarm from being triggered in garages with
elevator ramps, for instance, or when the
vehicle is transported by trailer or train:
