If the warning light
comes on when the ve-
hicle is in movement,
switch the engine off immediate-
ly and contact Alfa Romeo Au-
thorized Services.v
Low engine oil level
This warning light stays on for approx.
15 seconds, after the check, when the
engine oil level is low.
With the ignition key at MAR, pressing
the check button, the warning light turns
on but must go out after approx. 6 sec-
onds.
The oil level is checked only pressing
the check button with the engine
stopped. If the engine is started during
the check, the check procedure is inter-
rupted.k
If the warning light
stays on after the
check, do not try to get
peak performance out of the en-
gine and top up the oil as soon
as possible.k
Insufficient oil pressure
This warning light should be out when
the engine is running.
When the ignition key is turned to the
MARposition the warning light comes
on and should go out as soon as the en-
gine is started. vLow battery charge
This warning light should be out when the
engine is running (a slight delay is permitted
when the engine is running at idle speed).
If the warning light comes on, Alfa
Romeo Authorized services should be con-
tacted immediately.
When the ignition key is moved to the
MARposition the warning light comes
on and should go out as soon as the en-
gine is started.w

76
Engine control system
(EOBD) failure
(optional for versions/
markets where applicable)
Normally, when you turn the ignition
key to MAR, the warning light must
come on but must switch off when the
engine is running. It initially lights up to
indicate that the warning light is working.
If the warning light stays on permanent-
ly or comes on when the car is moving:
1)With a fixed light- indicates
that the supply/ ignition system is mal-
functioning that could cause high exhaust
emissions, possible loss of performance,
bad driveability and high consumptions.
In these conditions, you way continue
to drive while avoiding asking a lot from
the engine or high speeds. The prolonged
use of the car when this warning light is
on could cause damage. Contact an Alfa
Romeo Authorized Service Station as
soon as possible. The warning light turns
off if the malfunction disappears, howev-
er the system stores the warning anyhow.
U
2)Flashing light - indicates that the
catalytic converter could be damaged
(see paragraph on “EOBD System” in
this chapter).
If the warning light is on and flashing,
take your foot off the accelerator and dri-
ve at low speeds until the warning light
stops flashing; continue travelling at a
moderate speed trying to avoid driving
conditions that could cause the warning
light to flash again. Contact an Alfa
Romeo Authorized Service Station as
soon as possible.
If, when turning the ig-
nition key to MAR, the
Uwarning light does
not switch on or if, when dri-
ving, the light flashes or emits a
fixed light, contact an Alfa
Romeo Authorized Service Sta-
tion as soon as possible.
Engine control system
(versions for markets where
applicable)
1) In normal conditions, turning the ig-
nition key to MAR, the dial warning
light turns on but it should go off when
the engine has started. The initial turning
on indicates that the warning light is
working properly.
2) If the warning light stays on or turns
on when travelling, it indicates a fault in
the supply /ignition system which could
cause high exhaust emissions, possible
lack of performance, poor handling and
high consumption levels.
In these conditions, it is possible to con-
tinue driving without however demanding
heavy effort or high speeds.
Prolonged use of the car with the warn-
ing light on may cause damage. Contact
an Alfa Romeo Authorized Service as
soon as possible.
The warning light turns off if the fault
disappears, but it is still stored by the sys-
tem.
U

77
Faulty ABS anti
wheel-locking
This warning light comes on when the
system is inefficient. In this case normal
braking is ensured without though, mak-
ing use of the ABS system. Alfa Romeo
Authorized Services should however be
contacted as soon as possible.
When the ignition key is turned to
MARthe warning light comes on but
must go out after approx. 4 seconds.>
Presence of water
in the fuel oil filter
(JTD 20V Multijet versions)
When the ignition key is turned to the
MARposition the warning light should
come on and must go out after approx. 4
seconds.
The warning light switches on fixed
when driving, to indicate the presence of
water in the fuel oil filter.
In case the indicator light switches on,
even if just for a few seconds, we recom-
mend to contact an Alfa Romeo Autho-
rised Service as soon as possible in order
to purge the water from the fuel oil filter
and avoid severe damages to the injec-
tion pump and to the fuel oil supply cir-
cuit as well as the engine irregular opera-
tion.
c
Glowplugs
(JTD 20V Multijet versions)
The warning light comes on
when the ignition key is turned to MAR
position. When the glowplugs have
reached the established temperature the
warning light will go out. Start the en-
gine as soon as the warning light has
gone out.
For versions/markets where applica-
ble, the warning light flashes for approx.
30 seconds after starting the engine
meaning that there is a fault to the glow
plug warning system, in which case,
contact Alfa Romeo Authorized Services.
With a high ambient temperature the
warning light may turn on imperceptibly.
m
The car is fitted with an
electronic braking device
(EDB). If the
>andxwarning
lights turn on at the same time, this
means that there is an EBD system
fault; in this case violent braking
may be accompanied by early rear
wheel locking, with the possibility
of skidding. Drive the car ex-
tremely carefully to the nearest
Authorized Alfa Romeo workshop
to have the system checked.
WARNING

79
Main-beam headlights
This warning light comes on when the
main-beam is switched on.
Cruise Control
(on request for versions/
markets where applicable)
The warning light turns on, with the
control switch in the ONposition, when
the device starts to act on the engine.
1VDC System (Vehicle
Dynamics Control)
(on request for versions/
markets where applicable)
Turning the ignition key to MAR, the
warning light on the instrument cluster
lights up and must go out after about 4
seconds.
If the warning light does not go out or s-
tays on when travelling, contact Autho-
rised Alfa Romeo Services. Although the
absence of the VDC function does not af-
fect the car safety, it is however recom-
mended to drive at moderate speed.
Flashing of the warning light when travel-
ling means that the VDC system has cut in.
áPassenger’s Air bag
deactivated
This warning light turns on when the
passenger’s Air bag is deactivated.
Warning light Findi-
cates also warning light
¬failure. This is indicated by in-
termittent flashing, over 4 sec-
onds, of warning light F. In this
event, warning light ¬could be
not up to indicate restraint system
failures, if any. Stop the car and
contact Authorized Alfa Romeo
Services have the system checked.
WARNING

90
The dust/pollen filter should be checked
over at least once a year by Alfa Romeo
Authorized Services, preferably at the be-
ginning of summer.
If the vehicle is habitually driven in pol-
luted areas or on dusty roads the system
should be checked and if necessary
changed more often.If the filter is not re-
placed the efficiency of
the climate control sys-
tem may be seriously compro-
mised.ACTIVATED CARBON
DUST/POLLEN AIR FILTER
The filter has the specific capability to
combine the mechanical air filtering func-
tion with an electrostatic effect so that
the outside air admitted to the passenger
compartment is purified and free of parti-
cles such as dust, pollen etc.
In addition to the above-mentioned
function there is also an effective reduc-
tion of the concentration of pollutants
owing to a layer of activated carbons on
the lower surface of the filter.
The filtering action takes place when air
is admitted from outside (recirculation
off) and when the air is recirculated (re-
circulation on).

92
The temperature near
the heater should never
exceed 120°C (e.g. dur-
ing body painting operations in
the workshop oven). Higher tem-
perature could damage the elec-
tronic control unit components.
For maintenance and repairs con-
tact only Authorized Alfa Romeo
Services and only use original
spare parts.
The burner exhaust gas
is released in the centre
floor area: therefore never park
the car with the engine running
over inflammable surfaces, fire
hazard!
WARNING
IMPORTANT When the heater is
working with the vehicle stationery and
the engine running, standing outside the
car near the rear wheel arch a low noise
caused by normal operation of the heater
can be heard.MAINTENANCE
Have the additional heater checked at
regular intervals by Authorized Alfa
Romeo Services. This will ensure safe,
cost-effective working of the heater and
also long life.

SECURING THE LOAD
The loads carried may be blocked with
straps hooked to the special rings in the
boot corners (fig. 140). The rings also
serve to secure the luggage retaining net
(available on request c/o Alfa Romeo Au-
thorized Services).
fig. 140
678PGSm
Do not load the luggage
compartment above the
permitted maximum (see “Techni-
cal specifications”). Also make sure
that the objects contained in the
boot are well secured to prevent
them from being thrown forward
causing harm to the passengers in
the event of sharp braking.
WARNING
A heavy load that has not
been secured may cause
serious harm to passengers in the
event of an accident.
WARNINGIMPORTANT Travelling at night with
a load in the boot it is necessary to adjust
the height of the low beam headlights
(see next paragraph “Headlights” in this
chapter). For correct use of the aiming
device, also make sure that the load does
not exceed the values given in the same
paragraph.

111
GAS DISCHARGE HEADLIGHTS
(optional for versions/markets where
applicable)
Gas discharge headlights (xenon) work
with a voltaic arc, in an atmosphere satu-
rated with pressurised xenon gas, instead
of the incandescent filament.
The lighting produced is remarkably
higher than that of the conventional light
in both terms of the quality of the light
(lighter) and of the amplitude and posi-
tion of the lit area.
The advantages offered by better light-
ing are noted (due to less sight fatigue
and better orientation capability of the
driver, thus of travelling safety) especially
in bad weather, fog and/or insufficient
signs, because of the higher lighting
of the side beams which are normally
shaded.
The heavy increase of lighting in the
side beams considerably increases driving
safety because it allows the driver to bet-
ter see other users at the sides of the
road (pedestrians, cyclists and motorcy-
clists).Very high voltage is needed to trigger
the voltaic arc, after which the supply can
be at low voltage.
The headlights reach their maximum in-
tensity after about 15 seconds from
switching on.
The high luminosity produced by this
type of headlight calls for the use of an
automatic system to keep the headlight
beam aiming constant and prevent daz-
zling other vehicles when braking, accel-
erating and carrying loads.
The electromechanical system for auto-
matic constant beam aiming makes the
headlight aiming device superfluous.
Xenon lights are very long-lasting and
failure is unlikely.
If necessary, have the
system checked and any
repairs done only by Authorized Al-
fa Romeo Services.
