2006 Alfa Romeo Brera/Spider sensor

If a failure is indicated, stop the car, turn
the engine off and then clean the sen-
sors. Make sure to be far from possible
ultrasound sources (e.g.: truck pneu-
matic brakes or pneumatic hammers).
If failure cause has been eliminated the
system will resume regular operation
and message + symbol on the display
will turn off.
If the warning light stays on, contact Al-
fa Romeo Authorized Services to have
the system inspected, although the sys-
tem keeps on working. If the failure de-
tected does not impair system operation,
the system keeps on working and fail-
ure is stored in order to be then detect-
ed by Alfa Romeo Authorized Services
at next inspection.GENERAL WARNINGS
When parking, take the utmost care to
obstacles that may be set above or un-
der the sensors. Objects set close to the
car, under certain circumstances are not
detected and could therefore cause dam-
ages to the car or be damaged.
Indications sent by the sensors can be
altered by dirt, snow or ice deposited on
the sensors or by ultrasound systems
(e.g.: truck pneumatic brakes or pneu-
matic hammers) set nearby the car.
TOWING TRAILERS
Sensors are reactivated automatically
when removing the trailer cable plug.
FAILURE INDICATIONS
The system control unit checks every
system component each time the key is
fitted into the ignition device. Sensors
and relevant electrical connections are
then constantly monitored during sys-
tem operation.
Sensor failure is indicated by message
+ symbol on the display (see section
“Warning lights and messages”).
Sensors operation is de-
activated automatically
when the trailer electric
cable plug is fitted into the car
tow hook socket.

The devices for curtailing diesel fuel en-
gine emissions are the following:
❒oxidising catalytic converter;
❒exhaust gas recirculation system
(E.G.R.);
❒diesel particulate filter (DPF).
PROTECTING THE
ENVIRONMENT
The devices for curtailing petrol engine
emissions are the following:
❒three-way catalytic converter;
❒Lambda sensors;
❒fuel evaporation system.
In addition, do not let the engine run,
even for a test, with one or more spark
plugs disconnected.
During normal service
the diesel particulate
filter (DPF) reaches high tem-
peratures. Do not therefore
park the car over inflammable
materials (grass, dry leaves,
pine needles, etc.): fire hazard.
