EOBD SYSTEM
The EOBD system (European On Board
Diagnosis) allows continuous diagnosis
of the components of the car correlat-
ed with emissions.
It also alerts the driver, by turning on the
warning light
Uon the instrument pan-
el (on certain versions together with the
message on the display) (see section
“Warning lights and messages”), when
these conditions are no longer in peak
conditions.
The objective is:
❒ to keep system efficiency under con-
trol;
❒ to warn when a fault causes emission
levels to increase;
❒to warn of the need to replace dete-
riorated components.
If when fitting the key
into the ignition device,
the warning light
U
does not turn on or if, while
travelling it turns on glowing
steadily or flashing, contact Al-
fa Romeo Authorized Services
as soon as possible. Warning
light
Uoperation can be
checked by means of special
equipment by traffic agents. Al-
ways comply with the traffic
regulations in force in the coun-
try where you are travelling.
The system also has a diagnostic con-
nector that can be interfaced with ap-
propriate tools, which makes it possible
to read the error codes stored in the con-
trol unit, together with a series of spe-
cific parameters for engine operation
and diagnosis. This check can also be
carried out by the traffic police.
IMPORTANTAfter eliminating the in-
convenience, to check the system com-
pletely, Alfa Romeo Authorized Services
are obliged to run a bench test and, if
necessary, road tests which may also
call for a long journey.

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 warning
tand the corresponding
warning message 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 front or rear part, under certain cir-
cumstances are not detected and could
therefore cause damages 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
Rear sensors are reactivated automati-
cally 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 turning on
of warning light
t(where provided)
on the instrument panel (on certain ver-
sions together with the message on the
display) (see section “Warning lights
and messages”).
Rear sensors operation
is deactivated automat-
ically when the trailer
electric cable plug is fitted into
the car tow hook socket.

The car can be equipped with the
T.P.M.S. (Tyre Pressure Monitoring Sys-
tem). This system consists of a radio-fre-
quency sensor, installed on each wheel
(on the rim inside the tyre) that sends
pressure information to the control unit.IMPORTANT NOTES
Failure indications will not be stored and
therefore will not be displayed when
turning the engine off and on again. If
failure persists, the control unit will send
warning indications to the instrument
panel only after a few seconds when the
car is moving.
Tyre pressure should be checked with
tyres cold. Should it become necessary
for whatever reason to check pressure
with hot tyres, do not reduce pressure
although it is higher than the prescribed
value but repeat the check when tyres
are cold (see section “Wheels” in sec-
tion “Technical Specifications”).
TYRE PRESSURE MONITORING SYSTEM -
T.P.M.S. (where provided)
The T.P.M.S. does not
exempt the driver from
checking tyre pressure, includ-
ing the space-saver spare
wheel (where provided) at
regular intervals.
WARNING
T.P.M.S. cannot indicate sudden tyre
pressure drops (e.g.: tyre burst). In this
event, brake the car cautiously and
avoid sudden steering.
The T.P.M.S. system requires special
equipment. Consult Alfa Romeo Autho-
rized Services to know what type of ac-
cessories are compatible with the sys-
tem (wheels, wheel caps, etc.). Using
other accessories could cause system
malfunctioning. Due to inflation valve
special characteristics, use only tyre re-
pair sealants approved by Alfa Romeo;
other sealants could cause system mal-
functioning.

CORRECT USE
OF THE CAR
Climate control
The air conditioner is an additional load
which greatly affects the engine leading
to higher consumption. When the tem-
perature outside the car permits it, use
the air vents where possible.
Spoilers
The use of aerodynamic optional extras
which are not certified for the specific
use on the vehicle, may reduce the aero-
dynamic penetration of the vehicle and
increase consumption. Unnecessary loads
Do not travel with too much luggage
stowed in the boot. The weight of the
car (especially when driving in town)
and its trim greatly affects consumption
and stability.
Roof rack/ski rack
Remove the roof rack or the ski rack
from the roof as soon as they are no
longer used. These accessories lower air
penetration and adversely affect con-
sumption levels. When needing to car-
ry particularly voluminous objects, prefer-
ably use a trailer.
Electric devices
Use electric devices only for the amount
of time needed. Rear heated window,
additional headlights, windscreen wipers
and heater fan need a considerable
amount of energy, therefore increasing
the requirement of current increases fu-
el consumption (up to +25% in the ur-
ban cycle).CONTAINING
RUNNING COSTS
Here are some suggestions which may
help you to keep the running costs of
your car down and lower the amount of
toxic emissions released into the at-
mosphere.
GENERAL CONSIDERATIONS
Car maintenance
Have checks and adjustments carried out
in accordance with the “Service sched-
ule”.
Tyres
Check the pressure of the tyres routine-
ly at an interval of no more than 4
weeks: if the pressure is too low, con-
sumption levels increase as resistance
to rolling is higher.
