– if the led continues flashing, but at dif-

2 flashes:

cables
7 flashes:

bles or cutting emergency

at least three causes of

WHEN THE ALARM
IS TRIGGERED
When the system is on, the alarm comes
into action in the following cases:
– opening of one of the doors, bonnet or
tailgate;
– disconnection of the battery or section-
ing of electric cables;
– intrusion in the passenger compartment,
for example breakage of windows (volu-
metric protection);
– attempt to start the engine (key in
MAR position);
– abnormal car lifting/sloping (for ver-
sions/markets where applicable).
Depending on the markets, the cutting in
of the alarm causes operation of the siren
and hazard warning ligths (for about 26 sec-
onds). The ways of operating and the num-
ber of cycles may vary depending on the
markets.
A maximum number of cycles is however
envisaged.
Once the alarm cycle has ended, the sys-
tem resumes its normal control function.

VOLUMETRIC PROTECTION

To make sure that the protection system
works correctly the side windows and sun-
roof (if fitted) must be properly shut.
The function can be cut off (if, for exam-
ple, leaving animals in the car) carrying out
the following operations in rapid succession:
starting from the condition with the igni-
tion key at MAR, move the key to STOP,
then immediately back to MAR and then
to STOP again, then remove the ignition
key.
The deterrent led (A-fig. 7) on the dash-
board lights up for about 2 seconds to con-
firm that the function has been cut off.
To restore volumetric protection, move the
and keep the ignition key at MAR for over
30 seconds.
If, with the volumetric protection function
deactivated, an electric control controlled by
the ignition key at MAR (e.g. power win-
dows) turn the ignition key to MAR, op-
erate the control and move the key to
STOP in a maximum time of 30 seconds.
This way volumetric protection is not re-
stored.
