EOBD SYSTEM
(for versions/markets,
where provided)
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.
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 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.
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 may be equipped with a Tyre
Pressure Monitoring System, which in-
dicates to the driver the tyre pressure
status by two different indications:
“Check tyre pressures” and “Low tyre
pressures”. For a detailed description of
the two indications, see the “Warning
Lights and Messages” section. This sys-
tem consists of a radio-frequency sen-
sor, installed on each wheel (on the rim
inside the tyre) that sends pressure in-
formation 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 MONITORING SYSTEM -
T.P.M.S.
(for versions/markets, where provided)
The T.P.M.S. does not
exempt the driver from
checking tyre pressure, includ-
ing the space-saver spare
wheel (for versions/markets,
where provided) at regular in-
tervals.
WARNING
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”).
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.

CAR INACTIVITY
If the car is to be left inactive for longer
than a month, the following precautions
should be noted:
❒ park the car in covered, dry and if
possible well-ventilated premises;
❒ engage a gear;
❒check that the handbrake is not en-
gaged;
❒disconnect battery negative terminal
and check the battery charge. This
check is to be repeated every three
months when the car is left inactive.
Recharge if the optical(where pro-
vided) indicator shows a dark colour
without the central green area (see
paragraph “Battery” in “Car main-
tenance” section);
❒clean and protect the painted parts
using protective wax;
❒clean and protect the shiny metal
parts using special compounds read-
ily available;
❒sprinkle talcum powder on the rubber
windscreen and rear window wiper
blades and lift them off the glass;
❒slightly open the windows;
❒cover the car with a cloth or perfo-
rated plastic sheet. Do not use sheets
of non-perforated plastic as they do
not allow moisture on the car body
to evaporate;
❒inflate tyres to +0.5 bar above the
normal specified pressure and check
it at intervals;
❒if you don’t disconnect the battery
from the electric system, check its
charge every month and recharge it
if the optical indicator shows a dark
colour without the central green area;
❒ do not drain the engine cooling sys-
tem.
IMPORTANTIf the car is fitted with
alarm system, switch off the alarm with
the remote control.

– Car heavy duty (e.g.: towing trail-
er uphill or fully laden car): decrease
speed, if the warning light stays on, stop
the car. Wait for 2 or 3 minutes leaving
the engine on and slightly accelerated to
further activate the circulation of the
coolant fluid, then switch the engine off.
IMPORTANTUnder severe use of the
car, keep the engine on and slightly ac-
celerated for few minutes before switch-
ing it off.ENGINE COOLANT
HIGH TEMPERATURE
(red)
Fitting the key into the ignition device,
the warning light (set on engine coolant
gauge) turns on but it shall go off after
a few seconds.
The warning light turns on (on certain
versions a dedicated message is dis-
played) to indicate engine overheating.
If the warning light comes on, proceed
as follows:
– Normal driving conditions: stop
the car, switch off the engine and check
whether the water level in the reservoir
is not below the MINmarl. Otherwise
wait for few seconds to allow engine
cooling, then open slowly and carefully
the cap, top up coolant and check
whether its level is falling between MIN
and MAXmarks in the reservoir. Check
visually any leak. If when restarting the
warning light comes on again, contact
Alfa Romeo Authorized Services.
u
With engine hot, do not
remove the cap: risk of
burnt.
WARNING

When the electronic key is inserted into
the starting device,
the warning light switch-
es on and should go out as soon as the en-
gine is started.
1. Low engine oil pressare
The warning light turns on and stays on con-
stantly (for versions/markets, where pro-
vided) along with the message on the dis-
play when the system detects that engine
oil pressure is low.– use of the vehicle for short drives, in which
the engine does not have time to reach its
regular operating temperature
– repeated interruption of the regeneration
process, signalled by the DPF warning light
coming on.
LOW BATTERY
CHARGE (red)
The warning light (where pro-
vided) turns on, but it should go
off as soon as the engine has started (with
the engine running at idle speed a brief de-
lay in going out is allowed).
If the warning light (or as an alternative, on
certain versions, a symbol and a message
are displayed) stays on glowing steadily or
flashing contact immediately Alfa Romeo Au-
thorized Services.w
v
If the warning light vturns on when the vehicle
is travelling (on certain versions
together with the message on the
display) stop the engine immedi-
ately and contact a Alfa Romeo
Authorized Services.
WARNING
2. Exhausted engine oil
(only Diesel versions with DPF)
The warning light will flash and a specific mes-
sage will appear on the display (for ver-
sions/markets, where provided). The warn-
ing light may flash in the following ways, de-
pending on the version:
– for 1 minute every two hours;
– for 3 minute cycles with the warning light
off for intervals of 5 seconds until oil is
changed.
After the initial warning, each time the engine
is started up, the warning light will continue
to flash in the above mentioned modes, un-
til the oil is changed. A specific message will
appear on the display (for versions/markets,
where provided) in addition to the warning
light. If the warning light flashes, this does
not mean that the car is defective but sim-
ply informs the driver that it is now necessary
to change the oil as a result of regular vehi-
cle use.
Note that engine oil is exhausted faster un-
der the following circumstances:
– use of the vehicle prevalently for city driving,
requiring more frequent regeneration of DPF
MINIMUM ENGINE
OIL LEVEL (RED)
When the electronic key is in-
serted into the starting device the
display will show the engine oil level for
a few seconds.
On some versions the display will show
a message and a symbol if the engine oil
level is too low. In this case, top up the
engine oil to the correct level (see “Check-
ing fluid levels” in “Car maintenance”
chapter).k
Exhausted engine oil
should be replaced as soon
as possible after the warning light
comes on, never more than 500
km after the warning light first
comes on. Failure to change the oil
within the first 500 km may result
in severe damage to the engine
and will result in forfeiture of the
warranty. Remember that when
the warning light flashes, it does
not mean that the level of engine
oil is low, so if the light flashes you
must not top up.
