IMPORTANT If the car is to remain i-
nactive for a prolonged length of time
(over three weeks) and security condi-
tions permitting, it is advisable to operate
central locking turning the key in the door
lock to avoid engaging the alarm and
draining the battery.
VOLUMETRIC PROTECTION
To guarantee correct operation, all the
windows and the sunroof (optional for
versions/markets where applicable)
should be closed. This function can be ex-
cluded (for example when leaving ani-
mals on-board the vehicle) by performing
the following operations in quick succes-
sion: when the ignition key is at the
MAR position, move the key to the
STOP position and then return the key
to the MAR and then once again to the
STOP position. Remove the ignition key.
The led in the vehicle will come on for
about 2 seconds to confirm that the func-
tion has been excluded.
To restore volumetric protection move
the ignition key to the MAR position
and hold it in this position for more than
30 seconds.
If requiring to activate an electric control
operated by the ignition key at MAR
(e.g. electric windows) with the volumet-
ric protection deactivated, turn the igni-
tion key to MAR, operate the control
and return the key to STOP within a
maximum time of 30 seconds. This way
volumetric protection is not restored.
CUTTING OUT OPERATION OF
THE SIREN
(optional for versions/markets where
applicable)
When requiring to dispense with the
siren acoustic signalling in the alarm con-
dition, simply keep the remote control
button (A-fig. 13) pressed for 4 sec-
onds when engaging the system.
This condition is shown by a series of 5
beeps in quick succession after the nor-
mal acoustic/visual signals when the sys-
tem is operated.
The next time the system is activated,
normal operation of the siren is restored
automatically.
