Alfa Romeo 147 Manuale Proprietario

– if the led continues flashing, but at dif-

ferent intervals than normal, this means that
different attempts to break in have occurred.
Through the number of flashes it is possi-
ble to identify the type of attempt:

one or more doors

tailgate

bonnet

ultrasounds

abnormal car lifting/slop-
ing (for versions/markets
where applicable)

tampering with car starting
cables

tampering with battery ca-
bles or cutting emergency
key cables

connection line to sensors
and siren

at least three causes of
alarm.

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.

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.
